Logic World news & patch notes

Single-file mods - Ecconia

Ever since Logic World released in early access, mod loading has been supported. Mods generally are dropped in the GameData/ folder.

Most mods are distributed as folders containing all their assets. But Logic World always offered to also load mods as archive files (.zip, renamed as .lwmod). But due to how Logic World was structured internally, archive mods have been missing much of the functionality available to folder mods. This made them unattractive for modders that knew of them.

At the beginning of 2025, I had enough of distributing my mods as folders, and I decided I wanted to use archive mods from then on. So, I set out to fix the deficiencies of archive mods. Now a year later, I can announce that archive mods are now fully supported by the game!

Why do we want to support archive mods?

Modders have always used folder mods. Folders are easy to edit, restructure and view, exactly what modders need. Even if you are not the creator of a mod, you can open up any mod and tweak it to your preference.

On the other side, if you wish to share a folder mod you will have to create an archive first. If you wish to download it, you must extract the archive you download. Most mods are distributed via GitHub, you can't just download a folder from a browser, it has to be archived. With folders mods you easily can move files into the wrong place and then enjoy wondering why things are not functional. Some modders host multiple mods in the same Git repository. Finding and selecting the right mods and folders from there has always caused confusion.

These are a lot of unnecessary steps for mod users. Why have these extra steps?

Archive mod files can be downloaded from a browser and used without file extraction. You can easily search for them due to the .lwmod file ending. If you ever wish to tweak an archive mod, simply extract it to convert it to a folder mod.

What did I need to fix?

There were two main problems with archive mods:

Localizor is no more more

Press F to pay respects to Localizor, which is shutting down on March 31.

We've been using Localizor to crowdsource translations for Logic World since 2020. Over the years, more than 200 people have contributed to Logic World translations. Thanks to this incredible community effort, today you can choose to play Logic World in 24 different languages!

This is quite amazing, and we'd like to extend our heartfelt gratitude to everyone who's volunteered their time to translate Logic World. Thank you all! You are very awesome!

We'd like to keep community translations going, so with Localizor's shutdown we'll have to find another system for it.

We're leaning towards self-hosting an instance of Weblate. Weblate is very widely used, and it has a bunch of features that actually make it an upgrade over Localizor. To see how Weblate looks and feels, check out this instance where Weblate itself is localized.

If you've helped translate Logic World in the past, or if you're interested in doing so in the future, we'd like to hear from you:

• Do you like Weblate? Do you think it's a good choice for us?

• If you used Localizor, or if you've used another translation tool, what did you like and dislike about it? What would you like to see in our new translations system?

I'm thinking about starting a Patreon - Jimmy

Progress on Logic World is frustratingly slow right now because I am not able to commit much time to the project. Logic World has a long way to go, and I really really want to spend all my time and energy turning it into the game it's meant to be. However, I do not have the money to do so.

Several people from the LW community have offered to help me out financially. I've been reluctant to accept donations due to a bunch of complicated emotions, but after a lot of reflection I think it might actually make sense.

Here's a candid breakdown of my finances:

• After Steam's cut, sales of Logic World sales bring in roughly $1000/month, although this is very unstable and fluctuates significantly.

• Some of that ~$1000 is distributed among the other developers, and some goes to business expenses like hosting costs for logic.world. In the end I make roughly $800/month from LW.

• In my part of the world, a small studio apartment costs about $1100/month, and spartan groceries are about $250/month, for a total barebones living expense of ~$1350/month.

(For simplicity, all $ values are presented in USD, although I live in Canada.)

So, I'm about $500/month away from having enough money to sustain a minimal existence on LW income. If I had the security of a reliable extra $500/month, I think I would feel comfortable working on LW full-time again. The game would get done a lot faster, and I would be a lot happier in life.

$500/month in crowdfunding feels achievable to me. This would only take 100 people giving $5/month, or 50 people giving $10/month. Am I crazy for thinking that this could happen? Logic World's community isn't huge or anything, but a couple hundred people play the game at least once a month, and about twice that number read the discord.

We (myself and the other devs) were discussing what perks we could offer to patrons. Here's some ideas we had:

• In-game cosmetics for your character.

  • We joked about giving patrons a gold chain necklace with a dollar-sign-shaped pendant. The dollar-sign pendant gets bigger the longer you've been a patron, until it's bigger than your entire head.

• Access to nightly builds of the game, so patrons can try new features as soon as we merge them in our development repository.

• A special role on Discord, and a special trophy for your profile page on logic.world.

• Access to a patron-only Discord channel and a patron-only Logic World server.

• Monthly patron-only streams/calls with myself and other developers.

• Names of patrons added to the in-game credits.

• Top patrons given a shout-out in these blogs.

So, here are my questions for you:

• Do you find this list of perks compelling?

• Would you contribute to my Patreon to support Logic World development? If you're on the fence or skeptical, what would sway you?

• Do you personally think it makes sense for me to try starting a patreon? Do you have any other ideas for how I might achieve financial stability while working on Logic World full time?

Please let me know in the comments or in a private message. I am seriously very interested in hearing from you.

I'm super nervous to post this for some reason!! But thanks for reading it. Ok bye.

New loading bars - Ecconia

Starting the game used to take a lot of time, especially with 30 mods installed. Think of a Windows installer with its loading bar stuck at 99%. It's probably working, but it feels broken. In Logic World, there were no loading bars during startup.

The real issue wasn't speed. It was perception. If something moves or spins, you know progress is happening and you're more patient. If nothing happens, it feels like the program froze.

Nothing was shown because LogicWorld completed most of its initialization before rendering the first frame. That meant staring at a blank screen for more than 15 seconds.

There were other issues as well. If you tried to close the game during startup, it kept loading anyway and only exited after finishing initialization. On Windows, you might even get the beloved and pointless "LogicWorld is not responding" popup.

The solution is to load the game over multiple frames, which I have now finished implementing.

Profiling - Ecconia

I've also added a new profiler to measure what's taking up time while the game is starting. This has already allowed me to make some improvements in startup time, which you can see in the video above.

Here's some example output from my new profiler. You can make the game save a log file with profiler output by launching the game with the new startup argument --profile-startup.

As you can see, the profiler allows us to measure precisely how long it takes to get between two points in the code. This system is available for modders as well, using the LogicProfiler API.

I was motivated to add the profiler by my work on making .lwmod files fully functional so modders can easily distribute their work as single-file drop-into-the-mods-folder packages. I had most code done, but encountered a performance regression. The game loaded even slower than before. I started optimizing slow parts, but did not achieve good results. Now that I have the profiler, I can figure out why .lwmod files are loading slower than folder mods, and hopefully .lwmod files will be fully supported soon.

Get the preview now!

You can try the improved game startup in a new preview version we released today! Just opt into the "Public Previews" Steam beta.

Changelog: v0.92.3 Preview 57

Here are all the changes in today's preview since v0.92.2 (the current stable version).

Game startup

• Added loading screen with progress bars for game startup (applies once Unity has finished loading, which takes about 5 seconds).

• Fixed not being able to quit the game during startup quickly (via common window/process controls).

• Game start is much more robust and will show errors in settings files as well.

• Improved language loading performance by ~2.7x.

• Improved settings loading performance by ~3x.

• Improved debug command loading performance by ~6x.

Launch options

• Client startup arguments now start with two dashes -- instead of one dash -.

• Added client startup argument --help which prints command help on startup.

• Added client command argument --profile-startup which generates a profiler log file of the startup.

• Startup arguments for Unity and mods must now be appended after a -- separator argument. Example for Unity argument --screen-fullscreen: ./Logic_World --open-save "demo_world_official" -- --screen-fullscreen.

Modding

• Added ClientMod.GameStartupCompleted(). This is called after the game has finished loading, but before it starts background tasks (like game loop / networking).

• A new LogicProfiler API is now available for measuring the execution time of your code. Currently, it only works while the game is starting up.

• Improved error message if a component type is missing placing rules.

Miscellaneous

• Updated engine version to Unity 6000.0.65f1.

• Improved Unity physics settings to increase performance in very large worlds.

• Made some code more robust when the error-screen is opened during world load.

• Fixed demo world prompt causing an exception in main menu (once seen).

• Fixed some DOTween warnings in console.

Hello and welcome to the first Logic World Wednesdays of 2026! I hope this year brings you peace and joy. It will certainly be a big year for Logic World, so let's get into the blog!

Sometimes we have multiple writers on these blogs, but this one is written entirely by and from the perspective of me, Jimmy.

New schedule!

You may recall from this video that in September 2025 I switched to working on Logic World full-time. I gave myself the deadline of January 1st by which to grow Logic World revenue enough to cover my rent and food. In the months since, we shipped the Subassembly update, the Demo World, subassemblies on the Creation Hub and many other improvements to the game & website; I also learned a lot about marketing and distribution, and we successfully got Logic World in front of new audiences, driving up sales significantly.

However, January 1st has come and gone, and I was not able to make enough money through LW for it to sustain my full-time work on it. I believe we'll get there eventually, but for the time being I'll be joining the rest of the team in working on LW part-time only. I remain dedicated to getting it done, and I'll continue to be the project lead until we hit 1.0 (+ probably also beyond 1.0).

With my reduced hours on the project, Logic World Wednesdays is switching from a weekly blog to a monthly blog. For the foreseeable future, we'll publish a new LWW on the last Wednesday of each month, updating you on the progress we've made during that month.

I'm already feeling way better about my work on this game now that I'm not staking my entire financial future on it. Although I'll be working fewer hours on Logic World, I'm more excited and energized for those hours, and I will make them count!

New music!

Markku is working on new music for the game! The first single from Logic World: Volume 2 just came out. Listen to it while you read the rest of this blog:

You can get Now, We Fly on Spotify, Apple Music, Youtube Music, and several other music places.

Volume 2 will be similar in length to volume 1, around 40 minutes in total. I think you'll love what he's cooking up for volume 2 -- Markku does phenomenal work, he's so good at driving the emotions immanent to the Logic World experience, and I couldn't be more excited to be working with him again.

Markku's music from volume 1 plays at arbitrary intervals during gameplay, but with the music of volume 2 we're looking at playing the pieces more contextually and intentionally. For example, Now, We Fly has this sense of grandeur, epicness and triumph to it. We want to really maximize the emotional impact by waiting to play it until you've spent many hours building up a huge and complicated machine. Everything has come together, your big project finally works, you're marveling at the expansive yet intricate operation of the whole thing, and BAM we hit you with this music. I think it's gonna work really well!!

One more thing: the cover art for this single was made by Markku himself! He started learning Blender specifically to make it. (Ecconia joked that it's more like "now, we swim" but Markku explained that the inverter is nervous about flight, and the music will give it the courage to fly up out of the water :))

New codebase!

We've mentioned this before, but never outlined it in detail: we are rewriting Logic World from scratch.

Among other reasons, we're doing this in order to dramatically increase performance & scalability. Logic World is about beholding and exploring the majesty of emergent computational complexity: many simple logic gates working in tandem come together to form astonishingly capable machines, and the core of LW is to apprehend such phenomena. With the rewrite, we're pushing this pillar to the next level.

Currently, Logic World can handle around 10 million simulated components before performance issues make it impossible to continue building. Our initial goal for the rewrite is to increase that number by a factor of 100, achieving 1 billion simulated components at a stable 60fps. Hence, our name for the overall effort is Project One Billion, or POB for short. However, in the long term, we believe we can get that number significantly higher than just one billion.

Here's a little preview where I'm testing the data structures we've designed for this purpose. A billion components, initialized in 30ms, using <50MB of real-world RAM.

POB isn't just about enabling singular builds with a huge amount of RAM or CPU cores or a giant display or whatever. It's also about enabling vast shared worlds for multiplayer. Our ambition is to turn Logic World into an MMO-scale experience. Think of a big computer you've seen in LW -- this one, perhaps. Now imagine you and a hundred other people each have your own computer like it in one shared world, and you've connected them to an in-game internet where you can send code and data between the different computers. Visions like this inspired me as I began development on Logic World all those years ago, and this is the kind of paradigm shift that POB will make possible.

Now that we've shipped subassemblies and the Demo World, we've done everything we wanted to do with the legacy codebase, and the majority of development effort is now focused on the rewrite. We started planning the architecture of POB in December of '23, and we started writing the code for it in February of '25. Now it's finally our full focus, and '26 will be the year that POB blossoms into glory!

I'm really, really excited about this. With POB, I think we're going to make a game that is truly magical and totally unprecedented. We've learned so many important lessons through building Logic World the first time, and our second take on this game is going to be so much better in every way. We'll share lots more on the blog this year as POB takes shape.

I want to end this introduction to POB by giving due credit to my colleague Zoey. She was the first to realize that something on the scale of POB is actually possible, and she conceived many of the core concepts that the new codebase is being built around. When we're all playing with gigabytes of simulated RAM in LW, it will be thanks to Zoey's efforts and inventiveness. I'm extremely grateful that I get to collaborate with someone so brilliant on this ambitious next stage of Logic World's development.

New runtime!

One thing I love about being a .NET developer is that it's fast. It gives developers an extensive and well-designed suite of high-level tools that provide huge productivity boosts unavailable in lower-level languages, but even so, apps written for .NET can match or (in some very specific cases) even exceed the performance of bare-metal languages like C++ and Rust.

Every year, a new version of .NET is released that makes it even faster. If your hyperfixations overlap with mine, you might enjoy Stephen Toub's blog posts about the performance improvements in each new version of .NET. When I started writing code for POB, it was on .NET 9, but .NET 10 has since released and so I took some time this week to upgrade the project for those sweet sweet performance gains.

In the new codebase, we're investing in robust diagnostics, including a comprehensive benchmark suite to track performance changes over time. This is useful for ensuring that accidental performance regressions don't sneak in, and also for measuring the gain from performance improvements.

I ran the benchmark suite on .NET 9 and .NET 10, and I was pleased to see a number of benchmarks with significant performance improvements! Here are the results for our most-improved benchmarks. Each of these functions may be run millions of times per second, so improvements of even a few % lead to serious gains.

New freedom from twitter!

We're officially quitting twitter. There will be no more tweets from Logic World or Mouse Hat Games!

Thanks for reading! We'll see you on January 28th for the first LWW of the new monthly schedule. If you want to make sure you don't miss it, you can sign up for our newsletter.

Ciao!

For the first time ever, Logic World is on sale! Until January 5, you can save a massive 42% on the best 3D logic simulator around.

If you don't own Logic World yet, you can get it now for an incredible bargain!

You can also get Logic World for your friends! Studies show that Logic World makes the perfect holiday gift. Plus, when both you and your friends have Logic World, you can play it together in multiplayer!

Hey gamers! There's a new Logic World update out, and you can download and play it now.

The highlight of update 0.92.2 is the Demo World. This is a world we've put together to introduce new players to the game. It's got information about how to play Logic World, a guide to getting started with digital logic, and a bunch of cool things to check out as you wander around.

In addition to the Demo World, this update has a number of minor tweaks and fixes. As usual, you can read the full details below :)

Let us know in the comments what you'd like to see in the next Logic World update!

Full 0.92.2 changelog

Demo World

• Added the Demo World, a pre-built save file with an introduction to the game and some cool stuff to look at.

• The first time you start the game, there's now a little bubble on the main menu that says "Check out the demo world!" which points to the 'Singleplayer' button.

• The Demo World can be reset by deleting the save, or renaming the file on disk, and restarting the game.

• Added secret setting: MHG.Secret.RecreateDemoWorldWhenNotFound

Graphics

• Tweaked Ambient Occlusion to look better.

• Ambient Occlusion is now enabled by default again.

Building

• You can now confirm a Grab or Clone placement by pressing the return key.

• Fixed an issue where wire ghosts could display the incorrect state.

UI

• Action Wheel: changed the default size of the Action Wheel from 1.0 to 0.85.

• Color picker: changed the default value for the setting "Quick Picker Open State" back to "Always Open to Quick Menu".

• Chat: fixed a crash to error screen if you receive a chat message while you have the UI hidden.

The number of this week's LWW is a Mersenne prime. Savour the feeling, because this may be the last time it will ever happen.

The Demo World

Logic World is extremely cool once you sit down and spend several hours building stuff, but when you first start playing, it's pretty empty and unexciting. While there's a certain charm to watching everything grow from nothing, and bringing about that transformation entirely by your hand, the initial emptiness is a pretty bad and underwhelming experience for new players who are just getting started with the game. We can definitely do better.

If you ever played TUNG, the old prototype for Logic World, you may have fond memories of the "Demo World" that we built for that game. When you start up TUNG for the first time, it prompts you to "Check out the demo world!", and in that demo world there are a series of simple circuits laid out for you to explore, analyze, and learn from.

We're brining this idea back in Logic World. We're making a new demo world for players to drop into when they first boot up the game. It has an overview of the different features of the game, an introduction to some beginner digital logic concepts, and a few big & complex circuits to show how cool the game can get. We hope it'll be a great introduction to Logic World.

In the long term, we'll be adding interactive tutorials, challenges, and a campaign mode to give people a rich and polished first-time experience, but that will all take a while to design and develop. In the short term, adding a demo world is something we can do pretty quickly to dramatically improve the first-time player experience.

Here's a quick teaser screenshot of the demo world we're working on:

We're trying to move fast with this. We aim to release a preview version of LW with this demo world in the next few days, then release it as a finished game update next week.

New trailer & screenshots - Jimmy

The Logic World trailer, and the screenshots shown on the store page, are some of our most important marketing assets, giving many people their first impression of the game. Both of these have not been updated since 2021, before the game first launched in Early Access. I'm working on a new trailer, and a new set of screenshots, to better showcase the game and reflect the changes to Logic World over the last four years.

So I'm asking you now: have you built something cool in Logic World, or do you know of a cool build, that you'd like to see in official promotional material? I'd truly love to include your work in the new trailer, and make it a showcase of this community's best creations.

Let me know in the comments, or DM me on Discord.

That's all for today! See you next week for Logic World Wednesdays #2^7.

Welcome back to Logic World Wednesdays, your weekly digest of everything the Logic World team has been up to.

We released update 0.92.1 last week, and it seems to have gone over well, with no reports that the update catastrophically broke anybody's computer and deleted all their data. Hooray!

Anyways, here's what's new with us.

Ambient occlusion tweaks - Jimmy

Our ambient occlusion has looked kind of grainy and bad ever since we updated to Unity 6. This week I took some time to tweak it and reign it in to look more normal and good.

After

You might have to open these images separately to see the difference; it's pretty subtle. Look at the edges where two surfaces meet.

Creation revisions - Felipe

This week I added a highly requested revision system for creations that allows you to upload an improved version of your world or subassembly without having to make a separate creation:

Pictured: @Sc0ttB0x's Hard disc V1

This means that it's now much easier to fix an issue about your circuit that you only found after uploading, all you have to do is click the "Upload new revision" button in the revisions tab of your creation, then go back to the game window and upload the subassembly or world as usual.

We also hope to use this system in the future when mods are introduced to the Hub, along with some improvements like more granular version numbers and game compatibility.

Store page work - Jimmy

I've been working on our Steam store page. My goal is to present Logic World in a way that efficiently communicates what's so great about this game. It's an important part of my broader goal to increase revenue from Logic World enough to cover my rent and groceries. When people who would enjoy Logic World see the store page, I want them to think "this game looks great, I will buy it immediately!"

The most notable change since the last LWW is that I redid the "About this game" section. I completely rewrote the text, and I recorded + edited three videos of LW gameplay to embed in the text.

My favorite part is a section I added at the end with three of my favorite quotes about Logic World. I'm very proud to have received these endorsements, and I personally think this section is quite convincing!

I'd love to get your feedback on the store page. In particular, I'd like your opinion on whether three embedded videos right next to each other is too overwhelming, or whether it works for you.

Please check it out and let me know what you think:

The multiplayer event was great and there were no bugs at all

On Saturday, we hosted a multiplayer server and invited anyone who wanted to join. The purpose was to get some screenshots and videos of multiplayer gameplay for use in promotional materials.

We announced this casually on Discord a few days in advance, so I figured maybe four or five people would show up. Instead, TWENTY-EIGHT PEOPLE JOINED THE SERVER.

This was astonishing and utterly chaotic. We absolutely smashed the world record for the most people on a single Logic World server, which I think was previously around ten.

You can clearly see the event in this graph of the Steam player count, courtesy of SteamDB:

Thanks to everyone who joined! Some of the footage from the event is already live in the "Multiplayer" video if you scroll down on the Steam page. Maybe you can spot yourself there?

Next-gen networking tech (and a very important request)

The previous heading was a lie. There were actually a lot of bugs. People were out of sync with each other, there was severe server lag, and occasionally people's games would straight up crash.

Most of the issues seemed to stem from our networking stack. We use Lidgren.Network for networking, and neither Lidgren itself nor the way we're using Lidgren are well-optimized for a large number of players. When we stress-tested the game by connecting 28 players to a single server, the networking just couldn't handle it.

In the long run, this simply won't do. Our ambition for this game is to scale it to MMO levels, with hundreds or thousands of people playing in one shared world.

We've been discussing what our next-gen networking solution will look like for a while, but as we watched the current networking solution fall apart this week, those discussions became a lot more serious and we started forming an actionable plan.

It looks like we're going to write a brand new, bespoke networking library that's tailor-made for Logic World. It's very early right now, but we have three goals with this project:

Hello! We're releasing a game update today to fix some issues. There isn't much else to say about it so I'll wrap it up here lol. More updates soon!

Here's everything new in 0.92.1:

Outlines

• Added setting: "Outline Style"

• Added two new outline styles, "Fast" and "Balanced". These are alternative outlining techniques that look worse in exchange for more performance. The old outline style is now called "Beautiful".

• The default outline style is now "Balanced".

• Changed the default outline thickness from 5 to 4.

• Fixed a visual issue where the color of outlines would be affected by the Resize Component UI.

Graphics

• Fixed some shadows not disappearing if you disable shadows after they were previously enabled.

• Fixed the hole at the top of the mountain in the Test World not rendering correctly.

• Fixed the multiplayer avatar preview looking like crap if accessed in the main menu with SHINY BOBBY enabled and real-time reflections disabled.

• Realtime reflections are now disabled by default.

• Added settings preview image for Realtime Reflections Enabled.

Help menu

• Flip is now shown while placing/grabbing/cloning a flippable object.

• Board Rotation Up/Down is no longer shown when placing/grabbing/cloning a flat board.

UI

• Fixed the text box for sliders sometimes showing the wrong value after manual modification.

• Fixed a small booger-shaped visual artifact in the text box for sliders.

• Fixed not being able to bind some keys (i.e. Escape, Back Mouse Button) because they close the keybind edit UI.

• Fixed some UI errors when selecting certain languages in the Languages menu (Estonian, Brazilian Portuguese and Hebrew).

Networking

• The client now prefers connecting via IPv4 if both IPv4 and IPv6 appear to be available for the client and the server that you want to connect to.

• Fixed client-side configuration of 'MHG.Networking.Secret.InternetProtocolOverride: IPv4' not working in a certain edge case.

Protocol

• The Download Menu now supports logicworld:// v1 links.

• Fixed an issue with incorrect protocol handling when the game is launched with a logicworld:// link.

Building

• When you place a subassembly with multiple roots, the game now properly saves the placement info (i.e. rotation, flip state, etc) for all the roots. When you place a multi-root subassembly multiple times, all roots will be placed the same way you set it on the preceding placement.

• Fixed a bug where a peg could visually show as being in the wrong state after it was moved, if the move deleted a wire that was powering it.

• Fixed a StackOverflowException when a very large number of pegs are connected.

• Slightly improved the performance of calculating the circuit graph.

Miscellaneous

• Fixed an issue that prevented worlds from loading if they contained a modded component with more than 255 output pegs.

• Improved the code for verifying player identities, which appears to have fixed an issue some people would sometimes see where attempting to join a verified server would fail with a "failed to obtain challenge response" error.

• Improved the help text for a few command-line parameters of the dedicated server.

• Changed the internal name of the Shadow Cascades setting, which prevents errors with trying to parse the old value.

• Fixed the Back Mouse Button and Forward Mouse Button being swapped on Linux.

Is it Wednesday again already? Yes it is. Wow. Nice. Cool. Good.

Update next week!

We're basically done Logic World update 0.92.1, which fixes many minor issues with update 0.92. We intend to release 0.92.1 next week.

You can test the almost-finished update right now in the public-previews branch. Instructions for that along with a changelog for today's preview update are at the end of this post.

Are there any last minute changes or fixes you really want to see in this update? Let us know!

New outline styles - Jimmy

Logic World uses an "outline" effect to highlight certain objects in the world. The outlines have been problematic recently and so this week I staged an intervention.

A brief history of outlines in Logic World

In the earliest prototypes for Logic World, then called The Ultimate Nerd Game, I used a library called Outline Effect by Cakeslice. When I had performance problems, I ended up forking Outline Effect into a library called Outline Effect But It's Faster. This was my very first time doing open source work!

Later, TUNG/LW was moved to Unity's Universal Render Pipeline, which broke all graphics effects made for earlier Unity versions, so we had to find a new outline solution. We ended up going with a modified version of PRO Outline by Knife Entertainment.

However, PRO Outline was made before 2020. In 2020, Unity broke all graphics effects made for earlier Unity versions (again). We put off updating Unity for a long time because of annoying crap like this, but in Logic World 0.92 we finally updated Unity and so PRO Outline didn't work anymore and we had to find a new solution.

We ended up going with the Wide Outline from Ameye's Linework, which uses a really cool jump flood algorithm to give us exceptionally high-quality outlines.

While these outlines look great, they unfortunately have some performance issues. Lag from these outlines is especially noticeable by folks on integrated GPUs and especially when there are a lot of outlines visible simultaneously (such as when using the Resizing building mechanic).

Fixing the lag

To improve performance on the devices that aren't suited to the new and expensive outlines, I decided to add a new setting to choose the outline algorithm the game uses. We'll keep the existing outlines around as the high-end option while adding an option to use a faster outline method instead.

Initially I wanted to code up a brand new outline system for this, with a balance of visual quality and performance perfectly tailored to Logic World's use case. I started working on this, but it was taking way too long, and I sort of lost motivation on it because A) Unity's APIs are super annoying to work with and B) this system, being closely tied to Unity APIs, would have to be completely thrown out when we switch to Godot in 0.100.

So I instead looked into premade options for outlines, and I determined that the best option was to add the other two outline options from Linework. The old jump-flood outlines are now called "Beautiful", and there are two new options: "Balanced" which looks fine and is much faster, and "Fast" which looks like crap but has only a very small performance impact.

In this table you can see what the new outline options look like and their relative performance. I've elected to do this comparison with the Resizing UI since that's where you see some of the most technically complex outlines in the game.

Seeing these numbers, I decided to make Balanced outlines the new default. If you want to retain the same outline visuals (and performance impact) from 0.92, you'll have to manually change the Outline Style setting to "Beautiful" after updating to 0.92.1.

This should solve all those performance issues for people! Now, hopefully I don't have to touch outlines ever again. Until we move to Godot and it has to all be redone from scratch.

Creation Remixes - Felipe

A few days ago I was browsing the Logic World Discord server and noticed a few people iterating on the design of a circuit, sharing each attempt as a subassembly on the Hub. When I opened each one to see the implementation, I realized that it would be great if you could properly link two creations and say "this one is based on that one" without having to manually write this in the description and add a link.

Thus, when uploading a creation you may now specify which existing creation it is based on (or "remixing"), which will show a link to the original creation on the sidebar of the new one:

Pictured: @CrispyPin's Game of Life: 36 components

It's worth noting that this is different from the concept of creation versioning (which will be coming soon 🤞): a remix implies that the new creation is based on another but doesn't unconditionally improve on it (maybe different tradeoffs were made, e.g. it's faster but also bigger), whereas a new version means that the older versions should generally not be used and that the new one is plain better (e.g. it fixes the output not being correct).

0.92.1 Preview 41 changelog

Here's everything new in 0.92.1 Preview 41, since Preview 21 last week. You can play it right now by opting into the 'Public Previews' Steam branch. opting into the 'Public Previews' Steam branch.

Outlines

• Added setting: "Outline Style"

• Added two new outline styles, "Fast" and "Balanced". These are alternative outlining techniques that look worse in exchange for more performance. The old outline style is now called "Beautiful".

• The default outline style is now "Balanced".

• Changed the default outline thickness from 5 to 4.

• Changed the minimum outline thickness from 1 to 2.

• Changed the maximum outline thickness from 50 to 20.

• Fixed a visual issue where the color of outlines would be affected by the Resize Component UI.

Other stuff

• When you place a subassembly with multiple roots, the game now properly saves the placement info (i.e. rotation, flip state, etc) for all the roots. When you place a multi-root subassembly multiple times, all roots will be placed the same way you set it on the preceding placement.

• Fixed the Back Mouse Button and Forward Mouse Button being swapped on Linux.

• Fixed not being able to bind some keys (i.e. Escape, Back Mouse Button) because they close the keybind edit UI.

• Fixed StackOverflowException when a very large number of pegs are connected.

• Slightly improved the performance of calculating the circuit graph (disclaimer: you won't notice).

0.92.1 Preview 54 changelog

Editing to add this section 2025-11-15: we just released Preview 54 as a followup to Preview 41. Here's what's new.

Graphics

• Fixed some shadows not disappearing if you disable shadows after they were previously enabled.

• Fixed the hole at the top of the mountain in the Test World not rendering correctly.

• Fixed the multiplayer avatar preview looking like crap if accessed in the main menu with SHINY BOBBY enabled and real-time reflections disabled.

• Realtime reflections are now disabled by default.

Outlines

• Balanced outlines no longer have configurable width. Their width is locked to a low value to ensure good performance. (Other outline styles don't get significantly slower with high widths, but it absolutely tanks performance on Balanced.)

• Reverted the changes to min/max outline thickness from the last preview.

Help menu

• Flip is now shown while placing/grabbing/cloning a flippable object.

• Board Rotation Up/Down is no longer shown when placing/grabbing/cloning a flat board.

Miscellaneous

• Added settings preview image for Outline Style.

• Added settings preview image for Realtime Reflections Enabled.

• Fixed the text box for sliders sometimes showing the wrong value after manual modification.

Hello gamers! It's been two weeks since update 0.92 came out. We've seen a positive reception to it, with player numbers we haven't seen since launch and many new people joining the Logic World discord. Most of all, we've enjoyed all the subassemblies you've uploaded to the Creation Hub. Thank you for playing!

Improvements and fixes for 0.92.1

Despite 0.92 not being very old at this point, we have already noticed and fixed a few issues for 0.92.1, as you can see in the remainder of this section. On this note, when you read this, the new preview version should already be live, so if you want to help us test (or would like the latest fixes and are not afraid of potential new bugs), please, once again, select the public-previews branch in steam.

Networking - GHXX

Almost 30 years ago, IPv6 was conceptualized and now, thanks to a new modem, it appears that I can finally use it. Logic World also supports IPv4 and IPv6, but in 0.92 (and before) preferred IPv6 if both were available. There was no real reason for this choice, however it does pose a bit of an issue if a server is wrongly advertising that they support both v4 and v6 (by having an A and AAAA DNS record respectively). This is because Logic World at some point needs to decide between using the v4 or v6 address when connecting, and may choose the wrong one. Technically both should work, but in this special case the v6 address for some reason did not work, likely due to a networking issue unrelated to Logic World. Unluckily, as the DNS entries are provided by a third party, it is not possible to remove the AAAA (IPv6) entry and thus fix the problem. Regardless though, preferring v4 by default is probably a better approach any way as v4 is supported everywhere whereas v6 is not, and as a side-effect, it also fixes that one misconfiguration. Therefore Logic World now prefers v4, unless only v6 is available.

Speaking of preferring v4, turns out that the secret setting MHG.Networking.Secret.InternetProtocolOverride: IPv4 was also broken if v6 was available, but that is also fixed in the preview version.

World loading - GHXX

On Saturday, one person also reported that they could not load their modded save file anymore, as it turns out the Logic World save loading code somehow only supported components with less than 256 outputs due to a tiny oversight, but that is fixed now, so now you can make even crazier modded components!

Dedicated server cleanup - Ecconia

Not sure if you've been affected by it. There was some confusion because the dedicated server binaries were stored in versioned folders (net6.0 through net9.0). We did this a while ago to take advantage of the latest .NET performance improvements and still allow players to use Harmony, which required an older version. We've reverted that change. The folder with the server binaries is now called Server again, same as in the normal game.

Circuit state chaos - Ecconia

The never-ending hunt for circuit states that visually have the wrong state... This week @colon_three managed to reproduce a bug that led to wires and pegs showing the wrong state — thanks a lot. This has now been fixed. But I bet there are still more bugs causing incorrect circuit states.

Old settings startup issues - Ecconia

We have a lovely, capable settings framework. But it wasn't designed to handle value migration between versions. However, the game breaks if you update from the last main version to the current one. This was because the setting for ShadowCascades used different values. When we updated Unity, those values changed, causing a crash. To fix this, we renamed the settings key for shadow cascades. That way, the old value is no longer parsed. We so gonna improve this with Godot rewrite.

0.92.1 Preview 21 changelog

Here's everything new in 0.92.1 Preview 21, which you can play right now by opting into the 'Public Previews' Steam branch.

• Fixed broken world loading for modded components that have more than 255 outputs.

• Fixed client-side configuration of 'MHG.Networking.Secret.InternetProtocolOverride: IPv4' not working in a certain edge case.

• The client now prefers connecting via IPv4 if both IPv4 and IPv6 appear to be available for the client and the server that you want to connect to.

• Fixed a bug where a peg which got moved had visually wrong state, when a wire powering it got deleted by the move.

• Corrected server startup argument description for working / root directory.

• The Download Menu now supports logicworld:// v1 links.

• Fixed an issue with incorrect protocol handling when the game is launched with a logicworld:// link.

• Renamed the setting MHG.Graphics.ShadowCascades to MHG.Graphics.ShadowCascadeCount. This prevents the game crashing trying to parse the old value.

Steam page experimenting - Jimmy, Eliana

Our Steam page hasn't really been updated since the early access launch in 2021. It's looking pretty outdated and crufty, which is bad for us. We want people arriving to the Steam page to have a good impression that makes them likely to wishlist or purchase.

Thus, we're going to overhaul the Steam page, and we've already started experimenting with a new capsule image (brighter, more "fun") and a new short description (less cringe, more descriptive).

Old

New

Something I'm interested in hearing from you: what qualities of a Steam page make you want to wishlist/purchase a game? What could we change about Logic World's steam page to make it better, in your opinion?

Goodbye

We'll keep working on more fixes, as we've got a pretty long list of details to tidy up. We're also working on some bigger things for beyond 0.92.1, but we will tell all about them next Wednesday -- see you then :)

Hello gamers,

We've been hard at work on a new Logic World update for you, and it's out now!

Highlights of update 0.92:

• Added Subassemblies: groups of components and wires that you can save and reuse elsewhere.

• Subassemblies can be uploaded and shared on the Creation Hub.

• Added Fixed Perspective: by pressing a keybind (default: double-tap Left Alt) you can freeze the camera in place, but still interact with the world by moving the mouse around on the screen.

• Tons of bug fixes.

• Tons of performance improvements, especially for very large builds.

• Lots and lots small details have been improved and polished.

The full changelog is at the bottom of this post.

Playing and yapping with us, the dev team

To commemorate this update, we sat down to play it together. While we played, we read through the changelog and gave our commentary as well as behind-the-scenes info on the development of this update.

Thank you

A huge thanks to the many people who played the 0.92 previews. Your feature feedback and bug reports got this update over the finish line. We couldn't have done it without you!

More to come

We've got lots more to do on this game. We're determined to make Logic World the best circuit-builder ever.

More updates are coming soon. If you want to be the first to know, subscribe to our newsletter and join the Logic World discord.

Full 0.92 Changelog

Here's everything new in Logic World 0.92, since 0.91.3.

Subassemblies

• You can now save "Subassemblies" -- groups of components and wires that you can reuse across different worlds and servers.

• You can save subassemblies with the Action Wheel or with a keyboard shortcut (default Ctrl+K).

• Added a new tab to the Selection Menu for your saved subassemblies.

• Added a menu for viewing and editing details of a saved subassembly.

• You can press a button in that window to upload your subassembly and share it online.

• Subassemblies shared online can be downloaded in-game. If you're playing in a world when a download completes, the downloaded subassembly will be added to your hotbar.

• Subassembly thumbnails are cached on disk. You can edit these files to make custom thumbnails if you want to!

• Via manual editing of a subassembly's meta.jecs file, you can add custom search tags to a subassembly.

• Added command: Subassemblies.SaveCurrentSelection \

• Added command: Subassemblies.AddToHotbar

Building

• Added "Fixed Perspective" feature. By pressing a keybind (default: double-tap Left Alt) you can freeze the camera in place, but still interact with the world by moving the mouse around on the screen.

• When you've confirmed a placement, it will now immediately become solid. Previously you would need to wait for the server to process the placement, which could take a while when there are a lot of changes.

• Significantly improved performance of Resizing operations for components with many children.

• Significantly improved performance of Grab and Clone operations for large objects.

• Improved performance when selecting a large number of components.

• The "Place Wire" input action is now marked "tap to toggle" by default, so you can either click-and-drag to place wires like before, or you can click on one peg to select it and then click on a second peg to create a wire between them.

• Pressing the Delete key (default R) while drawing a board will now cancel that action.

• The "failed action" sound now plays when you fail to place an item from the hotbar.

• The "delete item" sound now plays when a Clone action deletes a wire.

• Placing wire ghosts is now smoother visually, especially when there is server lag.

• The Help menu will now inform you that you can hold Ctrl for free rotation when Grabbing or Cloning on a smooth surface.

• Changed the default binding of Offset Hold to H.

• Fixed visual flickers when toggling board flatness during board drawing.

• Fixed resizing or rotating a board never working when a very large number of components are placed on it.

• Fixed an exception with Resizing that could happen if you tried to resize an object before the server finished confirming a previous building operation. In these cases, the Resize operation will fail now (and you can try again a moment later).

• Fixed an exception when you finish a Resizing operation when another player moved that component while you were resizing it.

• Fixed a crash to error screen when resizing a component where a wire is attached at both ends to that component.

• Fixed not being able to undo placing or deleting a wire after deleting an object attached to the wire.

• Fixed a placing issue with Standing Displays that have four pegs where they would act like 2x1 components instead of 2x2.

• Fixed game-killing StackOverflow errors when building with deeply nested component trees.

• Fixed the Edit Display Menu closing instantly if you're editing multiple Displays and you change their peg counts.

Components

• Updated the default Display configurations. In order to see the new defaults, you have to start a new sandbox, and delete your DefaultExtraData/MHG.DisplayConfigurations folder if you have one.

• Fixed new display configurations sometimes being a grayscale gradient instead of the intended rainbow.

• If a Key is hacked to not be bound to an input, it will now display "\" on its label. (Previously it would display "FancyInput.RawInputType.None" which was way too long and looked bad. Don't worry, hackers, we're looking out for you.)

• The text on top of Keys is now flush with the surface of the key, so it doesn't float in the air above.

• Fixed the text on top of Keys being outlined when you look at the base of a Key.

• Fixed anomalous behavior when trying to place an object on the very top of a Flag.

• Flags will now continue to flap in the wind uninterrupted when you change their color.

• Fixed the Flag's thumbnail looking too dark.

• Fixed typo in the name of the Drum instrument "Splash Cymbal" (it was previously called "Splash Cymba l").

• Fixed Label text escaping its bounds in some cases where there's a lot of whitespace in the text (#271).

• Fixed a minor UI issue where the shown state of inputs would be incorrect when you start editing a display configuration.

• The hint text that shows up while sitting in a chair, telling you how to leave the chair, is now localized. Also, the hint now shows the correct key if you change it to something other than escape. Also, it has a little shadow now to make it easier to read.

Music

• The in-game music is now less repetitive, and a given track will now never play if it was in the previous 5 played tracks. This number can be configured with the new secret setting MHG.Secret.MinSongHistoryDistance

• Music files are now distributed as ogg vorbis instead of mp3, meaning smaller files with better quality.

• The music player will now ignore non-music files inside music folders instead of trying to play them.

• New music won't start playing anymore if the pause menu is open.

Graphics

• Added an option for 8192x8192 shadow maps.

• Added an option for three shadow cascades (previously only 1, 2, and 4 were available).

• Added new anti-aliasing options for FXAA and SMAA.

• (Temporarily) removed the anti-aliasing options for MSAA.

• Added setting: "Motion Blur" (disabled by default).

• Tweaked the Bloom and Ambient Occlusion effects to be more subtle.

• Ambient Occlusion is now disabled by default.

• Text that appears physically in the world (the text on Labels, Keys and Singers) is now affected by the lighting in the world.

• SHINY BOBBY now properly reflects HDR content such as the teleporting VFX.

• Removed the setting for drawing shadows on additional lights, which was confusing and unnecessary as there are no additional lights in the game.

• Added new settings preview image for the Bloom setting.

Graphics APIs

• Vulkan is now the default graphics API on Linux. This gives a substantial performance increase and all the stability issues should be fixed now. If you still need to use OpenGL, it's available with --force-glcore.

• Removed support for OpenGL on Windows. The only backends available on this platform now are Direct3D 11 (used by default) and Vulkan (available with --force-vulkan).

Outlines

• Overhauled outline visuals. They are now much crisper and higher quality.

• Adjusted the layering of outlines to improve clarity in situations where many objects are outlined.

• Added settings for having a different outline intensity where the object being outlined is obscured.

• Added settings for all the built-in outline colors.

• Removed the settings for "Outline Fill" (which might come back later) and "Outline Corners" (which is meaningless in the new system).

• Looking at a player no longer outlines an object that's hidden behind that player.

• Fixed many cases where outlines were incorrect, missing, or flickering.

• Added secret setting: MHG.Secret.Outline.NoWorldMeshing. This reverts a new outline optimization (in case of issues).

Simulation speed

• Improved client-side performance and fixed a memory leak when the simulation speed is very high.

• You can now pause, resume, and step the simulation using keyboard shortcuts while the UI is hidden. (#512)

• Many aesthetic tweaks to the Simulation Speed menu, including new icons to make it more clear whether the simulation is running or frozen. The "running" icon is animated.

• Added secret setting: MHG.UI.SimulationSpeedMenu.RunningIconRotationDegreesPerSecond

• Fixed some layout issues with the Simulation Speed menu.

Hotbar

• The hotbar is now hidden during Grab and Clone operations, during Multi-Select, and during wire placing.

• Pressing a number key that is higher than the number of items in the hotbar will now select the last item in the hotbar, instead of doing nothing.

• Major improvements to scroll input handling for scrolling through the hotbar in environments where scroll input is not discrete. This includes MacOS with the default system settings, and all OSes when using a touchpad.

• The "next hotbar slot" and "previous hotbar slot" bindings now have options for horizontal scrolling by default (in addition to the existing options for vertical scrolling). This is mostly relevant when using a touchpad, as it allows you to scroll through the hotbar by scrolling the touchpad along the same axis as the hotbar is laid out.

• Fixed being able to hover over and interact with hotbar items while the chat window is open.

• Fixed being able to hover over the hotbar item in-between areas while not dragging a hotbar item.

Upload menu

• Improved the layout of the Upload menu.

• Pressing the "Cancel" button during an upload no longer closes the Upload menu.

• Pressing the "Back" keybind (default escape) during an upload now cancels the upload and closes the Upload menu.

• If an error occurs during an upload, the error will now be shown on screen along with a "Retry" button.

• Fixed broken text on the "Cancel" button while a download is in progress.

• Removed the button to go to your singleplayer sandbox list after a successful download.

• Added a character limit to the download URL text box, also made the text box wider.

Color chooser

• Tweaked the Quick Color Chooser so there's no longer any "dead" space between the Big Clicky Colors.

• Color picker: the setting "Quick Picker Open State" now has a default value of "Remain in Previous State" (was previously "Always Open to Quick Menu").

• Quick Color Chooser: fixed an issue where one or more Big Clicky Colors could incorrectly display as selected after resetting the list of saved colors.

• Fixed the "show/hide sliders" toggle in the Color Picker menu having a WAY too-big icon.

Misc menu changes

• Main Menu: added a link to the Logic World Discord

• Added secret setting: MHG.Secret.MainMenu.ShowDiscordLink

• Improved the layout of the online services UI (in the top left of the Main Menu). (#234)

• Minor tweaks to the Multiplayer Menu (tabs are smaller, moved count to right side of tab, refresh button aligned better)

• We've reworked the screen you see when you're disconnected from a server. When the server sends a long disconnection message, the screen now handles it better, giving you a scrollbar instead of making the message tiny.

• The Help menu no longer states whether a binding is tap-to-toggle (this information was just visual noise/clutter).

• Fixed report bugs menu not opening when an error occurred during startup.

General UI

• Multiplayer settings avatar preview: fixed the location of the sun not being aligned with where Bobby is being lit from

• Multiplayer settings avatar preview: fixed the lighting from the world affecting the preview

• Fixed long localized text being displayed weirdly in settings tabs. (#80)

• Hotbar: fixed some weird visual glitchiness when trying to insert an item into the middle of a full hotbar.

• Added keyboard shortcuts for changing the selected tab while in a menu with tabs. By default these are ctrl+tab to go to next tab, ctrl+shift+tab to go to previous tab, and ctrl+\ to select a specific tab.

• Fixed an issue where links in text would be stuck in the "hovered" state if you move your mouse directly from one link onto another link with no time in-between where you're not hovering over any link.

• Several buttons in the game which open a URL when clicked ("Browse Creations" in the Main Menu and Download Creation Menu, the "Help Translate Logic World" button in the Languages menu, the new Discord button in the Main Menu) now show a tooltip of the URL the button opens when the cursor hovers over the button.

• Fixed the cursor looking way to big on Linux and MacOS when custom cursors are displayed, i.e. when hovering over the edge of a resizable menu.

• Added secret setting: MHG.Secret.CursorModeWhenCustomCursorActive

Input and controls

• When an input action is marked as "tap to toggle", that property is now optional. This means you can either tap once to turn it on, then tap again later to turn it off, or hold the button down and release later to turn it off.

• Added setting: "Tap to Toggle Time"

• Fixed weird behavior when editing controls while the game is paused, where no matter how long you waited between tapping the same key multiple times, it would always be considered a double tap (or a triple tap, or (much) more).

• Added secret setting: FancyInput.ScrollDeltaThreshold

• When displaying a binding for an arrow key, it will now show an icon of an arrow instead of text that says "Up"/"Down"/"Left"/"Right".

• When displaying a binding on MacOS, the Control, Option, and Command keys will use symbols instead of text (in accordance with Apple's Human Interface Guidelines)

• Several UI-related keybindings which were previously not editable have been added to the settings menu. You can find them under Controls -> User Interface.

Zoomies

• You can now only use the Zoom function (bound to Y by default) in the regular Building game state. It won't work in other first-person game states like Resizing and Grabbing.

• Fixed the Zoom binding conflicting with other input actions (it would previously conflict with Ctrl+Y for Redo).

• Fixed being able to get stuck zoomed-in if you opened a menu while zoomed-in.

Servers and Multiplayer

• The server will no longer print a "\ left the game" message when the player disconnects before fully loading into the world.

• Fixed the existence of duplicate, frozen players in multiplayer that would appear when multiple players join or leave the server within a short period of time.

• Fixed a server exception when a player gets kicked or joins with another client.

• Fixed the server console printing "Simulation speed set to TPS" whenever a new player joins. It now is only printed when the TPS actually gets changed.

• Fixed log spam when closing the server's input stream.

• Fixed the server command stats.server usually printing the incorrect value for server TPS.

• Improved the help text for some server command-line arguments.

• Removed the command-line arguments that would let you run the Dedicated Server in plaintext mode (--plain-text and -t). The dedicated server now always runs in plaintext mode. This is less buggy, more consistent between platforms, and it fixes an issue where text couldn't be entered on Windows 11.

Saving and Backups

• When the game saves, it now first writes the save data to a temporary file, preventing file corruption if the save process is interrupted.

• The backup creation timer is now saved and thus short sessions will no longer keep resetting the backup timer.

• Backup deletion is now more intelligent, discarding backups more slowly the older they are, meaning there will be many recent backups but also some quite old ones available in case you need to revert at some point. The behaviour is fully customizable in the server config.

• Merged config settings DoAutosaveWhileServerIsEmpty and DoAutoBackupsWhileServerIsEmpty into DoAutosaveAndBackupsWhileServerIsEmpty.

• The file paths to Backups have been made much shorter, which helps prevent issues on a certain operating system that limits paths to 260 characters.

• Fixed chance of a backup being corrupted when it was created at the same time as a save was created.

Online

• Updated the game to use the new HTTP-based Logic World Online Services API, which replaces the legacy gRPC API.

• Updated the protocol handling for logicworld:// links to use our new format for them (now called "logicworld:// v1").

• Added secret setting: MHG.Secret.Online.Endpoint

• Added server config value: OnlineEndpoint

Modding

• Reworked how dynamic prefabs and placing rules are defined in GameData and implemented in code. The new system is much cleaner and more flexible, and allows generating prefabs or placing rules based on all properties of the component, not just the peg counts. Mods that add components with dynamic prefabs or placing rules will need to be updated.

• Modders can now start the MultiSelector with an initial selection. Write some fancy selection modes!

• Added InjectTriggersInto to FancyInput context definitions. The MHG mod context definitions make use of this now. Modders can use it to inject keybindings to input contexts in the base game or in other mods. Very useful for adding custom building operations.

• Added a new property, ShouldBeOutlined, to component decorations and blocks. When set to false, these objects will not be outlined under any circumstances. This can improve outlining performance of complex modded components that don't need every part to be outlined.

• Added ability for modders to have CircuitBoard-like components which directly inherit the CircuitBoard class. These custom boards will behave like normal boards, but can't have extra custom data.

• Mods can now use C# language version 13 (was previously C# 7).

• Made the error message more helpful when a mod dependency cannot be found because that mod is not installed.

• Mod stacktraces now contain line numbers (a PDB file is generated).

• New Keybindings can now be added to the building game state via the FirstPersonInteraction class.

• Added some new methods to the JECS API.

• Added ModRegistry which allows modders to easily check which mods are installed/loaded and access their files.

• The client now sends mod versions to the server. Server-side mods can now deny connections from clients with an outdated version of the mod.

• Fixed mod BuildingOperations not being loaded consistently.

• Fixed mod GameStates not being loaded at all.

• When placing modded components on a server which does not support them, you now get an error sound and a console message instead of ghost components.

• The Selection Menu now hides components which are not available on the server.

• Fixed modded network packets failing to parse due to inconsistent mod load order between client and server.

• Packet IDs are now set authoritatively by the server. This allows optional mods to add new packet types, without breaking packets for clients that don't have the mod installed.

• Client-only mods will no longer be announced to the server (keeps network packet smaller & nice for mod-list privacy).

• When placing modded components/subassemblies on a server which does not support them, you now get an error sound and a console message instead of ghost components.

• Improved the disconnection message when the server rejects a client for not having the required mods. The message now contains mod versions, and it has some formatting to make the list easier to read. It also includes any not-installed optional mods as "suggested". Also, the list of missing mods is now ordered alphabetically.

• Add 'ClientDependencies' and 'ServerDependencies' to mod manifest files.

• Replaced mod manifest properties 'ClientOnly' & 'Optional' with 'Type'. The new property can have values: Normal (this is default), Optional, Independent, ClientOnly, ServerOnly.

Localization

• Updated translations and translator credits for Bulgarian, Chinese (Simplified), Croatian, Czech, Dutch, Estonian, Finnish, French, German, Hebrew, Hungarian, Japanese, Korean, Pirate, Polish, Portuguese (Brazil), Romanian, Russian, Slovene, Spanish (Spain), Swedish, Turkish, and Ukrainian.

• Slovene is no longer incorrectly called "Slovenia" in the game files.

Thumbnails

• Errors when rendering thumbnails are now handled properly and will result in a pink-and-black error texture.

• Added command: Thumbnails.RenderComponentToDisk \ \

• Added command: Thumbnails.RenderSubassemblyToDisk \ \

• Added secret setting: MHG.Secret.DiskRenderCommands_ThumbnailRenderProperties

• Replaced many of the MHG.Secret.Thumbnails secret settings with one mega-setting, MHG.Secret.ThumbnailRenderProperties

• Added secret setting: MHG.Secret.BigThumbnailRenderProperties

• Renamed the command ExportThumbnailCache to Thumbnails.ExportCache

• Renamed the command RegenerateThumbnailCache to Thumbnails.RegenerateCache

Export

• Removed OBJ export and the associated objexport commands.

• Added 3dexport commands, which support glTF and glb export of worlds and subassemblies.

Platforms

• MIDI input is now supported on Apple Silicon devices.

• The MacOS version of the game now has native binaries for Apple Silicon.

• Fixed links not properly opening in a web browser on some Linux systems.

Stability

• Significantly improved server performance when cloning or placing objects with large clusters (i.e. a lot of pegs all connected together). Previously this caused players to be stuck until they rejoind.

• Fixed that when the game tries to send very large network packets it would corrupt the network state instead of crashing.

Technical updates

• Upgraded engine version to Unity 6.

• Upgraded the server runtime to dotnet 9.0, which gives us about 10% more performance in server-side tasks like loading saves and running the simulation.

• Upgraded most of our DLLs to use netstandard 2.1.

• Updated Font Awesome to 6.7.2, which comes with dozens of new icons and many tweaks to existing icons.

• The game's config file format has been changed from .succ to .jecs. Your old config files will be automatically converted.

• Various fixes to JECS file formatting.

Commands and stuff

• Added command: Debug.ListBuildingOperations

• The command Debug.TargetInfo now additionally prints a component's depth in the tree and its number of nested children.

• Added secret settings: MHG.Secret.TrimStalePartialWorldsIntervalSeconds, MHG.Secret.MaxAgeOfStalePartialWorldsSeconds, MHG.Secret.PartialWorldDownloadTimeoutSeconds

• Added server config values: TrimStalePartialWorldsIntervalSeconds, MaxAgeOfStalePartialWorldsSeconds, CullStalePartialWorldActionsIntervalSeconds, MaxAgeOfPartialWorldActionSeconds

• Renamed the subassemblycache.* commands to partialworldcache.* and fixed them all not working.

Miscellaneous

• Improved player spawning: instead of spawning into the world at the origin and then immediately teleporting to your player location, you will now properly spawn into the world at your player location. This can significantly improve performance when loading into the world if your player location is far away from the origin and there is a lot of complicated stuff at the origin.

• Fixed occasional exceptions related to the help menu being spammed in the console.

• Fixed the ground becoming colorless and distorted during the teleport sequence if the teleport is to somewhere far away.

• Fixed your own shadow teleporting immediately when the teleport sequence is initiated. Your shadow now teleports at the same instant that you do.

• Fixed your own reflection teleporting immediately when the teleport sequence is initiated. Your reflection now teleports at the same instant that you do.

• Fixed the client's and server's data about world structures getting out of sync sometimes, leading to various bugs.

• Fixed issues where palette loading crashed the game on startup when palette was corrupted or not installed. (#448)

• When a Sandbox or Subassembly has a very long name, previously the game would create files/folders on disk with very long names. These file/folder names are now capped at 200 characters, which prevents crashes on Linux.

• Errors with the Integrated Server which occur before the server initializes (e.g. missing libraries) now show up in the game logs and debug console.

• Added Herobrine.

...and all through Mouse Hat Games, all the developers were blogging, writing sections and attaching their names.

Okay, but seriously, we're finishing up the next game update (0.92, The Subassembly Update) after exactly 19 months of work. It's a big update and we're very proud of it. It's the start of a new era for Logic World: the game has graduated from a janky proof-of-concept to a polished, stable experience. (In our opinion, at least.)

v0.92 will officially release one week from today, on October 22nd, 2025. We have a release candidate ready for testing now (more details at the bottom of this blog).

It's been a busy week for us as we prepare for the update. Here's some of what we've been working on!

Subassembly uploads - Felipe, Jimmy

We've added subassemblies to the Creation Hub! You can them check out live on the website at

https://logic.world/creations/subassemblies. Here's a video demonstration of uploading and downloading subassemblies from the hub:

We also did some polishing up of creation pages. There's a new sidebar, a refined carousel for screenshots, a new "Details" tab, and subassembly pages get an interactive 3D model!

Better Backups - GHXX

As some of you (unfortunately) may already have seen, Logic World automatically creates backups at regular intervals. I say unfortunately, as that generally implies that something went really wrong and you had to restore your world from a backup. And that is precisely the point. If something horrible happens we want to make sure there is a very high chance you won't lose your save -- especially since some people poured hundreds of hours into them.

In the past, the approach was rather simple, every now and then create a backup and if we have too many, throw the oldest ones away. Sadly the configuration was limited to just being able to determine how often backups are made and how many should be kept.

This comes with a bit of an issue, imagine you are running a multiplayer server with people playing every now and then and you don't realize that someone deleted important stuff. As the server does not crash, eventually all backups will be deleted that contained those now deleted builds.

A naive solution could be to simply extend the time between backups. While this would have been easily possible with the old system, this may cause your newest backup to be much older, making you lose more progress than before (if you decide to restore it).

Ideally we would combine the benefits of those two ways, so, keeping a few very recent backups and also some long-term ones. And this is exactly what the new system does!

There is now a so called Backup Schedule defined in the server config.jecs:

As already explained in the comments, there will be 4 very recent backups, and then the amount of backups per time is gradually decreased until the one-backup-per-week segment. You can add as many segments as you like.

For instance, when choosing 4*30s; 2*1m; 2*10m; 2*1h, you would end up with something along the following in your backups folder:

Keep in mind that making a backup twice a minute is way overkill, though helpful for developing so we don't need to wait for ages.

Now, the way it works is that based on this schedule, certain backups are dropped, and this happens more often in the smaller segments (30s, 1m) compared to the longer ones (10m, 1h). When a backup is created and there are now too many within such a segment, the extra ones in that segment are deleted, having the effect that few gradually move up into the longer segments. While nobody is playing, backups effectively do not age, so even if the server is inactive for a long time it will retain the proper scheduling.

So now you can finally have both short- and long-term backups which should make running multiplayer servers a bit less stressful. Or, if you ever accidentally delete a build that you really wanted, you can still dig it up in the backups folder potentially, provided you realize within 2-ish weeks of game time (if you are using the default schedule).

Perhaps as a small note, turns out backups had a chance of being incomplete if a backup was created exactly when an autosave happened. Though luckily that was never reported -- so likely nobody ran into it. Anyway, now it should be good.

To end on a positive note though, the timer responsible for triggering backup creation is now saved. Previously, when playing for short periods of time, e.g. 10 minutes, the backup timer would not trigger if it was set to, e.g. 15 minutes. When you would then reload the world, this timer would start out at 0 again, so no backup might ever have been made if you never played for long enough. Now this is properly saved between sessions (on a per-world basis), so you will always have backups now!

Bobavatars - Felipe

While browsing through some comment threads in the website I came across a couple discussions between users where none of them had uploaded an avatar of their own, which made it quite difficult to tell them apart and follow the conversation. To remedy this, I thought about adding identicons, which are little autogenerated icons that give each user a unique look based on something like their username or email. They’re a simple way to tell people apart without needing everyone to upload their own profile picture, and what better way to portray Logic World users than the very character they control in-game?

To that end, I've added automatically generated Bobby faces as the default avatar for all users, using colors derived from your username.

In the future we may add ways to customize your Bobby, and maybe even sync your in-game appearance settings with your logic.world settings!

Are you a logic.world user without a custom profile picture? What do you think of your new Bobavatar? Comment on this post to show it to the world!

Decrappifying the simulation speed menu - Jimmy

Since we introduced a menu to control the simulation speed, it's been a mess. To indicate that the simulation was running, we used a "play" icon, and to indicate that the simulation was paused, we used a "pause" icon.

This is actively confusing! In UIs like video players, it's standard convention to show the play icon while the video is paused, and show the pause icon while the video is playing. People expect the button icon to indicate what action is taken when the button is pressed, not the current state.

I've watched players get confused by this countless times, and I would constantly get confused myself while using the menu!

So to fix it, I changed the icons to a spinning "three connected nodes" to indicate a running simulation, and a snowflake to indicate a "frozen" simulation. I also added tooltips that should help reduce confusion further.

What do you think of these icons? How would you design this menu?

New boardlike API for modders - Ecconia

This year, @Astronand created a mod that adds transparent circuit boards to the game. Seeing this, I realized there is no way for modders to create components that behave like circuit boards.

Circuit boards have custom handling in the building code. This includes how they are drawn and placed or how components are placed on them. None of this is exposed through the API, and exposing this would require a significant refactor of the build system. This is something we should handle during the Godot rewrite.

For now, I added a workaround which allows modders to inherit the CircuitBoard class in their client component classes directly, letting their components behave exactly like normal circuit boards. With this workaround, it is not possible to extend them with additional custom data or change their shape. This limits what you can do with them. However, it is now possible to tweak the board's visuals.

LW-Glass by Astronand

Discord on the main menu - Jimmy

Pretty frequently, we get people who join the Logic World Discord who say something like "wow, I've been playing this game for ages and I never knew there was a discord." The number of people in the LW discord is also much smaller than the number of people who own the game. So, I think it's a safe assumption that lots of people don't know about the discord. Which is a shame, because the discord is the most vibrant and active part of the community right now, and anybody who wants to be part of the community ought to know about it.

To that end, I added a button to the main menu that you can click on to join the discord. Hopefully everybody will know it exists now!

This was a surprisingly challenging design problem. How do you make the button impossible to miss, without being annoyingly in the way? The main menu is starting to get pretty cluttered. What do you think of the placement?

Help us translate 0.92!

Logic World is translated by community volunteers into over 40 different languages! Every person who's helped translate the game is extremely cool.

We've pushed all the new translations from game update 0.92. There are 65 new things to translate, and 10 old translations that need updating. So, if you speak a non-English language and you'd like to help bring Logic World to that language, click here to check out the Logic World community translations.

A HUGE thank-you to everybody who's helped with translations, which is far too many to list here. You are all amazing!

v0.92 Release Candidate 1 is now available for testing

As we predicted last week, we have a release candidate for update 0.92 ready, and it definitely isn't a day later than we planned. The Release Candidate stage means that the update is 100% done and ready to go.

We need your help to make sure that RC1 is stable and bug-free. Please test this release, and send us any bugs you find forthwith, so we can have a maximally smooth update next Wednesday.

Get the release candidate by selecting properties -> betas -> public previews.

RC1 Changelog

Here are all the changes in Release Candidate 1 (v0.92.0.827) since the preview version we released last week (v0.92.0.731). The full changelog for update 0.92 (since 0.91.3) will be posted to our blog next week along with the release of the update.

Subassemblies

• Added an "upload" button in the Subassembly Details Window where you can upload your subassemblies to the Hub.

• The Download Creation Menu now supports downloading subassemblies from the Hub. If you're in-game when a download completes, the downloaded subassembly will be added to your hotbar.

Saving and Backups

• When the game saves, it now first writes the save data to a temporary file, preventing file corruption if the save process is interrupted.

• The backup creation timer is now saved and thus short sessions will no longer keep resetting the backup timer.

• Backup deletion is now more intelligent, discarding backups more slowly the older they are, meaning there will be many recent backups but also some quite old ones available in case you need to revert at some point. The behaviour is fully customizable in the server config.

• Merged config settings DoAutosaveWhileServerIsEmpty and DoAutoBackupsWhileServerIsEmpty into DoAutosaveAndBackupsWhileServerIsEmpty.

• Fixed chance of a backup being corrupted when it was created at the same time as a save was created.

Building

• When you've confirmed a placement, it will now immediately become solid. Previously you would need to wait for the server to process the placement, which could take a while when there are a lot of changes.

• Changed the default binding for "Use Fixed Perspective" to "double tap left alt"

• Reverted the change to the default binding for "Offset Hold" which is once again "left alt"

• For real this time, fixed the issue with mutli-wire placing where it could sometimes look like a miniature sun exploding on your screen, which it turns out was not actually related to outlines at all.

UI

• Minor tweaks to the Multiplayer Menu

• Multiplayer settings avatar preview: fixed the location of the sun not being aligned with where Bobby is being lit from

• Multiplayer settings avatar preview: fixed the lighting from the world affecting the preview

• The keyboard shortcuts for navigating menus with tabs (ctrl+tab, ctrl+shift+tab, and ctrl+numberkey), which were added for the new Selection Menu tabs, now work in all the other places with tabs (Settings Menu, Multiplayer Menu, and About Menu).

• Many aesthetic tweaks to the Simulation Speed menu, including new icons to make it more clear whether the simulation is running or frozen. The "running" icon is animated.

• Added secret setting: MHG.UI.SimulationSpeedMenu.RunningIconRotationDegreesPerSecond

• You can now press F5 to reload subassemblies menu.

• Download menu: the textbox is a bit wider now.

• Quick Color Chooser: fixed an issue where one or more Big Clicky Colors could incorrectly display as selected after resetting the list of saved colors.

• Fixed an issue where links in text would be stuck in the "hovered" state if you move your mouse directly from one link onto another link with no time in-between where you're not hovering over any link.

• Fixed an error screen you could get sometimes related to the subassembly categories.

• Main Menu: added a link to the Logic World Discord

• Added secret setting: MHG.Secret.MainMenu.ShowDiscordLink

• Several buttons in the game which open a URL when clicked ("Browse Creations" in the Main Menu and Download Creation Menu, the "Help Translate Logic World" button in the Languages menu, the new Discord button in the Main Menu) now show a tooltip of the URL the button opens when the cursor hovers over the button.

• Fixed the cursor looking way to big on Linux and MacOS when custom cursors are displayed, i.e. when hovering over the edge of a resizable menu.

• Added secret setting: MHG.Secret.CursorModeWhenCustomCursorActive

Settings

• Added new settings preview images for all outline settings and for the Bloom setting.

• Fixed outdated information in the description of the "Outline Thickness" setting.

Modding

• Added ability for modders to have CircuitBoard-like components which directly inherit the CircuitBoard class. These custom boards will behave like normal boards, but can't have extra custom data.

Miscellaneous

• Errors with the Integrated Server which occur before the server initializes (e.g. missing libraries) now show up in the game logs and debug console.

• Removed the command-line arguments that would let you run the Dedicated Server in plaintext mode (--plain-text and -t). The dedicated server now always runs in plaintext mode. This is less buggy, more consistent between platforms, and it fixes an issue where text couldn't be entered on Windows 11.

Release

• The game is no longer marked as a Preview version.

• Updated the text on the various About screens (Credits, Changelog, Roadmap).

We've been working on Logic World for eight years, and we've been sharing our progress on this blog for six of those. This week, we've decided to start counting our blogs, and it turns out this is the one hundred and twenty-second Logic World Wednesday. Numbering the blogs gives them a sense of their place in our overall journey. This blog is #122, so you can tell we've done a lot of work before today! And it makes us consider the future. What will this game look like when we reach LWW 200? or 300? We were inspired to start doing this by the Factorio crew, whose most recent blog is Factorio Friday Facts #438. If they never release another blog and we don't miss a single week, it will only take us 6 years to catch up 😉 Anyways, on to this week's news about Logic World, the indie video game we're building where you can invent a new computer!

The next update is just around the corner!

We're nearly ready to release Logic World v0.92, The Subassemblies Update. We're done adding features, and now we're just applying minor polish and fixes to the update to make sure it's rock solid stable and has great usability. We have a new preview version you can try out today (more info at the bottom of this blog) which is very close to the final 0.92 release. Our intention is to have a release candidate next Wednesday (October 15th). If no major issues are found in that release candidate, the update will be fully released the following week, on October 22nd. The Subassemblies Update has spent a long time in the oven and we're very excited to finally get it done and out :)

New URLs!

As we move to expand the scope of the online services we offer for Logic World, we've just completed a pass on all the URLs on our website. The new URLs are prettier, give more context for where they lead, and are future-proofed for new features we want to add later. Notably, our domain has changed from https://logicworld.net to https://logic.world. I think we can all agree that `logic.world` is far hotter and more awesome compared to `logicworld​.net` Here are some URLs before and after, let us know what you think!

Old URL

New URL

https://logicworld.net/hub

https://logic.world/creations

https://logicworld.net/view/frm-gnrldisc

https://logic.world/forum/general

https://logicworld.net/view/ctn-670fd9f9

https://logic.world/creations/worlds/4t8fUP/paint-processor-v2

https://logicworld.net/wishlist

https://logic.world/get-the-game

All the old logicworld.net URLs should redirect to their new home on logic.world. If you find any broken links, please let us know. There were a lot of details to consider with the new URLs, and it took a lot of team discussion to get it right, but we're very happy with where we landed. Here are a few new things we'll highlight:

The blog is special now

Gotos

Shortlinks

Fixed Perspective UX improvements

Better keybinding displays

New services API, now in the game

• It's easier for us to manage, maintain, and expand on.
• You don't need to maintain a constant connection to our server while using it.
• Your login token can automatically refresh, so if you open the game regularly, you'll never be logged out. (Currently "regularly" means at least once per year, but we may tweak this.)

Notification of upcoming price increase

v0.92 Preview 731 is now available for testing!

• Updated the game to use the new HTTP-based Logic World Online Services API, which replaces the legacy gRPC API.
• Added secret setting: `MHG.Secret.Online.Endpoint`
• Added server config value: `OnlineEndpoint`

• Outline thickness is no longer based on the screen resolution. Outlines should now look like they have the same thickness at 480p and 2160p.
• Updated the default outline thickness.
• Hopefully fixed the issue where outlines could sometimes become extremely bright and look like a miniature sun exploding on your screen.

• You can now only use the Zoom function (bound to `Y` by default) in the regular Building game state. It won't work in other first-person game states like Resizing and Grabbing.
• Fixed the Zoom binding conflicting with other input actions (it would previously conflict with `Ctrl+Y` for Redo).
• Fixed being able to get stuck zoomed-in if you opened a menu while zoomed-in.

• Changed the default binding for Fixed Perpsective from `` to ``
• "Use Fixed Perspective" is now a tap-to-toggle binding. This means that you can tap the key to toggle fixed perspective as before, but you can also hold it down to enable Fixed Perspective and then release it to disable Fixed Perspective.
• While Fixed Perspective is active, you can now use the player movement controls, as well as the keyboard looking controls.
• Moved "Use Fixed Perspective" to the "Looking" category of controls.
• Fixed the keybind hint for turning off Fixed Perspective not updating properly if Fixed Perspective is toggled while the UI is hidden.

• When displaying a binding for an arrow key, it will now show an icon of an arrow instead of text that says "Up"/"Down"/"Left"/"Right".
• When displaying a binding on MacOS, the Control, Option, and Command keys will use symbols instead of text (in accordance with Apple's Human Interface Guidelines)

• Fixed weird glitchiness with our "start typing to automatically focus a text box" functionality. This is used for search in the Selection Menu, the Edit Singer Menu and the Edit Drum Menu; as well as for the textboxes in the Chat window and the debug console. In all of these menus, you should now be able to start typing something without having the text box selected and it will Just Work again.
• The Help menu no longer states whether a binding is tap-to-toggle (this information was just visual noise/clutter).
• Hotbar: fixed some weird visual glitchiness when trying to insert an item into the middle of a full hotbar.
• Subassembly Detail Window: fixed some weird behavior when hitting return or escape while typing in the Title and Description text boxes.
• Missing mods disconnection screen: the list of mods is now ordered alphabetically.
• Download menu: fixed broken text on the "Cancel" button while a download is in progress.
• Download menu: removed the button to go to your singleplayer sandbox list after a successful download.
• Download menu: added a character limit to the URL text box.

• Removed OBJ export and the associated `objexport` commands.
• Added `3dexport` commands, which support glTF and glb export of worlds and subassemblies.
• After using the commands `Thumbnails.RenderComponentToDisk` and `Thumbnails.RenderSubassemblyToDisk`, the rendered image will now be shown in the system file manager after the render is complete.

• Updated engine version to Unity 6000.0.58f2.
• If a Key is hacked to not be bound to an input, it will now display "" on its label. (Previously it would display "FancyInput.RawInputType.None" which was way too long and looked bad. Don't worry, hackers, we're looking out for you.)
• Changed the default binding of Offset Hold to `H`.
• Fixed Font Awesome icons not rendering in regular text such as chat messages.
• Fixed the Flag's thumbnail looking too dark.
• Fixed the thumbnails of very large subassemblies being cut off.
• Fixed bug which prevents new subassemblies from appearing in the subassembly menu after the first rejoin.

The Rubening is Complete - Felipe

As I talked about previously, for the past couple months I've been working on rewriting the logicworld.net website and all our online services using the Ruby on Rails framework in order to tremendously simplify the whole codebase and development experience, thus making it easier to add new features.

I'm pleased to announce that everything is now running on the new codebase powered by Rails! The migration was performed on 2025-09-20 and it went pretty much as well as I could have hoped, there were only a couple minor issues that I sorted out soon after. Additionally, the server is now hosted in Germany, which means that our European-and-adjacent users should see an improvement in latency while hopefully still being quick enough for our friends over on the other side of the Atlantic Ocean.

This new website brings with it a bunch of miscellaneous improvements and bug fixes that I carried out along the way. They are mostly quality-of-life and reliability things, like not being able to change your profile picture at times, but there are a couple exciting things: you can now see the number of views on all posts, creations and tickets, as well as the number of downloads in creations! We unfortunately only started tracking them on the migration last week and as such we don't have data for views and downloads before that, but we hope this will make it easier to see how popular your uploads are in the future.

I also threw together a status page for this website, you can check it out by clicking the link at the page footer or by going to https://status.logicworld.net.

All in all, I'm very excited about the things that the new website will allow us to do to improve the Logic World online services!

Modding Mischief - Ecconia

Besides being a developer, I am also a modder. My contributions to the game often focus on making the modding API both easier to use and more powerful.

I made a bunch of mods, whose only purpose was to make modding easier. Over the last few months, I've integrated some of these mods directly into Logic World. Mods that have been integrated include ServerOnlyMods, FlexibleComponentModUsage, and one feature of EccsLogicWorldAPI.

The main thing I want to address today is the new Mod Type system. Modding in Logic World is complex because the game is multiplayer, meaning mods can exist on the client, the server, or both. We've previously handled this complexity with the ClientOnly and Optional boolean properties in the mod manifest, but in my opinion this is not granular enough and doesn't cover all the cases modders need.

After thinking it over, I came up with a new system where we have a single Type enum property in the mod manifest. Here is an overview of the different options.

Mod type

Normal

Optional

Independent

Client Only

Server Only

The table above shows how client and server treat mod loading and how the mod negotiation between both sides is configured.

Client and server both load mods on startup. Once a player joins a server, the client sends a list of loaded mods to the server. The server checks if all required mods are installed. If a required mod is missing the server disconnects the client with a message that lists missing mods.

Description

Example Usage

Normal

The mod needs to be installed on client & server. This is the default mod type.

A mod that adds new components.

Optional

The mod runs on both client and server, but clients without this mod can still join servers that have this mod.

A mod adding client-side tools that require support from the server-side.

Independent

The mod is loaded on client & server, but these sides don't talk to each other.

A mod adding a framework/library that other mods can use.

Client Only

The mod will only be loaded on the client.

A mod adding themes, new UIs, or new building mechanics.

Server Only

The mod will only be loaded on the server.

A mod that interacts with the game chat or adds server administration features.

If you have ideas or suggestions for Logic World modding, I'd love to talk about them with you! You can ping me in the #modding-general channel of the Logic World discord.

The Logic World modding API is a work-in-progress, and we do officially say that mod support is unofficial (for now). Despite this, there are an impressive quantity of mods for the game already, and I'm happy to be supporting the existing mod ecosystem. We're committed to building a 10/10 modding API for Logic World, and the recent modding updates bring us closer to our goal!

The text can finally feel the warmth of the sun and the cool of the shade - Jimmy

I finally fixed it

v0.92 Preview 613

We're releasing a new preview update today! This builds on the previous previews we've released for update 0.92. You can opt-in to the preview versions by selecting properties -> betas -> public previews.

Here's everything new in preview 613, since preview 599 last week:

Modding

• Add 'ClientDependencies' and 'ServerDependencies' to mod manifest files.

• Replaced mod manifest properties 'ClientOnly' & 'Optional' with 'Type'. The new property can have values: Normal (this is default), Optional, Independent, ClientOnly, ServerOnly.

• The disconnection screen for missing mods will now suggest missing mods of type "Optional".

• Fixed crash when placing a subassembly with a display configuration not present in the current world.

Miscellaneous

• Text that appears physically in the world (the text on Labels, Keys and Singers) is now affected by the lighting in the world.

• Color picker: the setting "Quick Picker Open State" now has a default value of "Remain in Previous State" (was previously "Always Open to Quick Menu").

• Rearrange the order of some controls in the settings menu.

• Fixed some missing English localizations.

See you next Wednesday :)

• Added command: `OpenDownloadCreationMenu `
• Added secret setting: `MHG.Protocol.EnableProtocolListeningOnUDP`
• Added secret setting: `MHG.Protocol.ListeningUdpPort`

• When Grabbing or Cloning on a smooth surface like Grasslands, you can now hold the Mod key (by default left ctrl) to rotate the object freely.
• Pick Component will now try to match the full detail of the component, if possible. For example, if you have both a red and blue circuit board in your hotbar and you use Pick on a red board, the red board in your hotbar will now be selected.
• Fixed several exceptions with Grabbing that could happen if you tried to grab an object before the server finished confirming a previous building operation. In these cases, the Grab operation will fail now (and you can try again a second later).
• Fixed exception when canceling a Resize operation if another player has moved or resized that component while you were resizing it.
• Fixed Resizing still moving child components around in a few edge cases.
• Fixed Resizing an object with wires attached without changing the component size causing wire ghosts to remain.

• If an undo or redo fails, a message will now be printed to the debug console.

• Fixed redo crashing the client if an undo operation previously failed.
• Fixed redo silently failing when trying to delete wires that were already deleted as a side effect of a component deletion.
• Fixed missing wires after undoing and then redoing a Clone operation with internal wires.

• Added a "Report a Bug" button on the Main Menu, Pause Menu, and Error Screen. Pressing this button brings up instructions for how to report a bug or issue with the game.
• In the Singleplayer menu, the Details pane for a saved game will now show which mods are in that save's registry.
• Fixed various issues with hotbar item management.
• Fixed the volume sliders in the Edit Singer and Edit Drum menus having an incorrect maximum value.
• Fixed the color chooser in the Edit Label menu not properly showing the correct selected color about 50% of the time.
• Fixed the Help menu flickering for a frame when you start placing an item on the hotbar.

• Added an experimental "Component Action" API. It allows sending custom bytes to a component between server and client.
• Added new manifest property `IncludeModInfoInSave`, which allows mods to control when their info (ID and version) are stored in save files.
• Cache folders will now be automatically deleted when switching/updating to different game version. This triggers a mod recompilation.
• Modders can now create and inject undo history entries.
• Multi-Undo build request sending now allows callbacks. (#398)
• Improved "mod has no mod type" exception messages to mention the issues with inheriting Server/ClientMod class.
• Mod compilation errors are now shown on the error screen, so you don't need to check the logs to see these errors.
• Fixed (new) mod instance creation failure detection hiding some other common exceptions (e.g. "Mod has no mod-type").
• Fixed a game crash in multiplayer when your game has modded components that the server does not have and a component deletion is undone.

• If there is an error with starting up the game, the error screen will now be properly shown with information about that error, instead of an empty black screen.
• Added a "Copy Error" button to the error screen. Please make use of it when reporting issues :)
• The error screen can now show stacktraces and other details in an expandable info box.
• Added secret setting: `MHG.UI.ErrorScreen.OpenErrorDetailsByDefault`

• Everything you see in server or client console will now be added to the log files.
• Log files will now contain stacktraces for exceptions.
• Command executions by player or console or LSF will now be logged in the log files.
• Improved logging throughout the program.

• Added server command-line argument: `--ansi-rgb`. This will make the server use Ansi RGB color codes in the plain text console. If the terminal supports RGB, colors will be accurate.
• Removed server LICC log file (log.txt).

• Unused components will no longer be added to world or subassembly save's component registry.
• Mods which provide components placed in the world will now be automatically included in the save's mod registry.

• When teleporting to another player, you no longer teleport inside them: instead you teleport next to them, looking at them. This is similar to how teleporting to Flags works.
• Fixed the `tp ` command not working.

• Added command-line startup option: `-open-save `
• Added command-line startup option: `-join-server `
• Added command-line startup option: `-open-url `
• The new command-line startup options take precedence over equivalent startup secret settings.
• Added command: `debug.printcommandlinearguments`

• Added WIP translations for Pirate Speak.
• Updated translations and translator credits for Czech, Estonian, Finnish, French, German, Hungarian, Japanese, Korean, Polish, Portuguese (Brazil), Russian, Slovenian, Spanish (Spain), and Swedish.

• Enabling or disabling noclip will now only print a message to the debug console if you do it via the `noclip` command. This prevents the console being spammed with messages if you use the secret setting `MHG.Flying.Secret.AutoEnterNoclipOnStartFlying`.
• Fixed copying messages from the client console sometimes copying rich text tags.
• Fixed a server memory leak on game save when no players are online.
• Fixed a rare case where the client and server failed to properly exchange component CustomData, leading to mess and disaster.

• We now properly handle several situations where a crash could become even crashier when trying to remove outlines.

0.91.2 Changelog

• Significantly improved loading times for larger worlds (>100,000 components) by batching collider instantiations.
• Fixed an issue that made hot-loads slower than cold-loads for larger worlds. All worlds now load faster hot than cold.
• Limited the maximum physics delta time to prevent physics death spirals. This should significantly improve framerates in large worlds for most cases.
• Sockets find their connections faster now. This means that initial world loading times are faster in worlds with lots of Sockets, and furthermore, placing or moving a lot of sockets at the same time will create less severe lag spikes.
• Server tick scheduling has been improved to reduce the amount of time the server can spend idle and not simulating the circuitry. Faster simulation speeds can now be accessed before the server starts skipping simulation time.
• The simulation now tries to catch up lost time over multiple server ticks, and only begins skipping simulation time once the simulation tick debt crosses a configurable threshold.
• Removed the server config value `MaxAllowedTimeStepSeconds`, and replaced with with the new server config value `MaxAllowedSimulationTickDebtSeconds`, due to the new simulation catch-up system described above.
• Assorted additional optimizations.

• Improved item movement during Multi-Grab and Multi-Clone operations. Items are much better at finding nearby valid placements, have a far greater tolerance for vertical displacement, and conform more strictly to their target rotations.
• Added secret setting: `MHG.Placing.Secret.MultiPlacementMaxVerticalVariance`
• Added secret setting: `MHG.Placing.Secret.MultiPlacementCastHeightIncrement`
• Edge extensions are now only enabled during fine placement, so it's easier to place circuit boards into tight spaces.
• Fixed false-negatives when detecting valid placements; you should now never be erroneously prevented from placing objects next to each other.

• By default, servers will no longer automatically save the game or make auto-backups while no players are connected. However, these behaviors can be restored by enabling the new server config values `DoAutosaveWhileServerIsEmpty` and `DoAutoBackupsWhileServerIsEmpty`.
• If the server is started with the command-line argument `--help`, it will now print a help text with available command-line arguments, and then shut down.
• If the server is started with invalid command-line arguments, it will now display an error message followed by the `--help` text, and then shut down.
• Disabled terminal prompt prefix `>` when the `--plain-text` server argument is set.
• The server console no longer waits for input before closing if there is an error on startup.
• Fixed exception on server shutdown if `AnnounceOnLocalNetwork` is turned off. (#484)

• New format for save files, Blotter v7, with minor binary formatting tweaks.
• Added save converter from v6 to v7 (Blotter v6 was used from Logic World v0.91.0 to v0.91.1).
• Added save converter from v5 to v7 (Blotter v5 was used from Logic World v0.90.0 to v0.90.3).
• The game will now automatically back up a save before converting it to a new save format version.
• When you create multiple saves with the same title, the on-disk filenames will now use an incrementing counter (i.e. `world`, `world (1)`, `world (2)`) instead of appended dashes (i.e. `world`, `world-`, `world--`).

• Hotbar title text now fades out after a short time with the same slot selected.
• Added secret setting: `MHG.UI.Hotbar.FullTextDuration`
• Added secret setting: `MHG.UI.Hotbar.FadeTextDuration`
• Fixed some glitches and inconsistent behavior with hotbar item management.
• Fixed base building UI rendering behind world geometry when another menu is open.

• Updated translations and translator credits for Bulgarian, Croatian, Czech, Dutch, Estonian, Finnish, French, German, Hebrew, Hungarian, Korean, Polish, Portuguese (Brazil), Romanian, Russian, Spanish (Spain), Swedish, Turkish, and Ukrainian.

• Added preprocessor symbols `LW_SIDE_SERVER` and `LW_SIDE_CLIENT` for compiling a section of mod code only the server or only on the client. (#489)
• Added a hook for post-parse save transformation to `SaveReader`, which mods can use to update their components.
• If a server-side mod fails to compile, the server will now immediately shut down instead of continuing to load the save with a mod missing.
• Client-side mod compilation errors now get printed at INFO log level. (#310)
• When a mod instance fails to load, the error message is now more helpful, and instructs you to try deleting the cache folders.
• Fixed CS1701 warning spam on client compilation error.

• Improved handling of exceptions during application initialization to prevent outrageous error spam.
• Fixed some exceptions being logged twice.
• Fixed the client being spammed with exceptions if another player joins or leaves near a barrier.
• Fixed exceptions when disconnecting from a server.
• Fixed a crash that could occur with a particular easter egg that pops up on Markku's birthday.
• Fixed not being able to join singleplayer games when UsePassword is enabled in `config.succ`. (#400)
• Fixed occasional erroneous floating wires not being removed when the game is reloaded. (#482)
• Fixed client crash to error screen on server rejoin when the server's simulation is struggling if the Simulation Speed Menu was not previously opened.

A New Update

A New Engine

• fun to work with,
• NOT UNITY, and
• free and open source software, so once we've moved our game to Godot we will truly own it and have control over it.

0.91.1 Changelog

• Multi-Placement systems have been drastically improved. It should now be much easier to place multiple items where you want them to be, and items should always have the correct starting placement when you begin moving them now.
• The system for determining the rotation of items being Grabbed or Cloned has been reworked. These items should never change rotation unexpectedly now when you move them to a surface with a different orientation.
• Added secret setting: `MHG.Placing.Secret.MaxOffsetVariantAttemptsPerItemPerFrame`
• Fixed a crash to error screen that could occur when grabbing or cloning multiple components (#475)

• Fixed not being able to resize components when they're placed in very specific locations (#471)
• Fixed cloned objects sometimes containing input pegs that remain On without being connected to any outputs
• Fixed using Offset Hold on a Flipped component resulting in a mirrored X offset value

• Fixed inputs on Through Pegs and Sockets sometimes erroneously starting Off instead of On after loading a save
• Fixed Delayers' internal counter state not being saved, and resetting to 0 on save load (#473)

• FOR REAL THIS TIME, fixed the infamous "cuddle bug", where you'd sometimes be shoved around by other players while someone was in the process of joining the server (#474)
• Fixed visual glitches for a short time after someone joins or leaves the server where other players would appear to move around very far and fast
• Fixed connected clients sometimes erroneously seeing the default server closing message when the server is closed with a custom message
• Fixed missing server console message to confirm the world has been saved to disk when the server is closed and `SaveOnClose` is enabled
• Improved the phrasing of various messages printed to the server console

• Finding Parcels: tweaked the color of some sounds and fixed some audio artifacts
• Time and Science: fixed the ending note being cut off abruptly. It now fades out fully to silence.

• Translations for WIP languages now include non-approved Google Translate suggestions
• Updated translations and translator credits for Bulgarian, Chinese (Simplified), Croatian, Czech, Dutch, Estonian, Finnish, French, German, Hebrew, Hungarian, Japanese, Korean, Polish, Portuguese (Brazil), Romanian, Russian, Slovenian, Spanish (Spain), Swedish, Turkish, and Ukrainian 🇺🇦

• Fixed OBJ export not working at all lmao
• Added command: `objexport.currentworld `
• OBJ exports should have much less texture duplication compared to 0.90.3. Textures are now reused where possible.
• Exported .obj and .mtl files are more human-readable compared to 0.90.3 thanks to added whitespace between objects, better organization of the data, and a few other improvements

• `token.dat` is now stored in the game install directory, next to the executable. This means your login is now specific to your installation of the game, instead of being shared by all installations on your machine.
• `token.dat` is now stored encrypted, with an encryption key and IV stored in a separate location on your machine. This means that in order to impersonate you, an attacker would now need access to two files instead of just one.
• Fixed the `LogicWorld.Online.Auth.ClearedToken` event never being invoked (#476)
• Added a smiley face when you log in using the browser

• Fixed incorrect integrated server paths on the Itch.io version, which prevented Itch.io players from loading singleplayer worlds
• The game handles input much better now if your binding for Multi-Select overlaps with your binding for a Build Action
• Fixed a crash to error screen when the main menu loads if you have a corrupted save file
• Added a check on application startup for whether the environment supports compute shaders, which are required to draw component/wire geometry since 0.91. If not, an appropriate error message will be displayed.
• Removed OpenGL support on MacOS, since OpenGL on MacOS does not support compute shaders
• Enabled Graphics Jobs and GPU Skinning in the player, which should provide a modest rendering performance boost

• If you hold the Mod key while flipping a row of switches, they will all be set to the same state as the first switch flipped (#60)
• Added secret setting: `MHG.Secret.InvertMultiSwitchInteractionModKeyBehavior`
• The input pegs on XOR Gates, AND Gates, D-Latches, Oracles, and Relays are now slightly longer

• Fixed the simulation unpausing in multiplayer when a new player joins the server even if the players currently on the server have paused it (#347)
• Fixed the simulation unpausing in singleplayer when accessing a sub-menu of the Pause menu

• Outputs that should start on (such as the outputs of newly placed Inverters) now start on in the simulation
• Fixed Clone operations not properly copying the circuit states of the original objects, which would often result in flickers and broken feedback loops (#116)
• Fixed component outputs sometimes erroneously changing state when the number of inputs is changed
• Fixed weird simulation glitches (and occasionally server crashes) that would occur when changing the number of pegs on a component that has connected output pegs (#104, #250)

• Significantly improved loading times, especially for large worlds
• Improved game framerates for most scenarios, particularly for large worlds, and particularly if post-processing or shadow cascades are disabled

• Component positions are now stored as fixed point rather than floating point
• Component world positions are now calculated in the reference frame of the stack root component
• Rounding of component rotations is smarter and more consistent

• Thumbnails are now anti-aliased
• Thumbnail lighting is now independent of environment lighting, so thumbnails will now always look consistent
• When a single component has an output that is supposed to start on, such as the output of an Inverter, the output is now properly rendered as on in the thumbnail
• Added command: `ExportThumbnailCache`
• Added command: `RegenerateThumbnailCache`

• Fixed incorrect footstep sounds being played in some situations
• Fixed new player positions not being applied until all overlay UI is closed

• Added support for outlining Interactables that are not part of components. This is used for the big clicky button in the test world, which is now outlined when you look at it.

• Added secret setting: `MHG.Secret.Interactables.StopInteractionIfLookingAtNonInteractable`
• You can now interact with the same Switch multiple times during one interaction
• When interacting with a Chair to sit in it, the interaction will now immediately end, instead of continuing while you sit in the chair. Fixes #103

• Changing Music Frequency will no longer cause music to stop playing (except when setting it to “Never”)
• Reloading the settings (i.e. by switching settings profiles) no longer causes the music to stop playing
• Tweaked the default parameters for the fancy pause menu music effects
• Music is loaded from disk more reliably; fixed music playback issues on some systems (#422)

• Fixed `InputPeg.AddPhasicLinkWith` throwing a `NullReferenceException` in many cases

• Dedicated server binaries are now placed in a sub-folder, to keep the root directory clean
• Periodic server tasks no longer cause a server death spiral if they take too long. This was often presenting when autosave was enabled on a very large world.
• If the server fails to broadcast its existence on the local network, it will now disable local network broadcasting instead of just crashing
• Reduced the minimum time between connections to a server from a single IP from 30 seconds to 3 seconds
• Messages in the server console announcing player leaves/joins are prettier

• Removed `config_override` files. All server config values are now stored only in `config.succ`
• There are far fewer disk writes related to game settings, especially on startup, which should improve startup performance

• Fixed the game not properly detecting supported network protocols, which was causing various nasty bugs that made the game unplayable in certain network setups or when no external network interfaces are available (#204, #333, #229)
• Updated Unity version from 2019.4.17f1 to 2019.4.40f1
• Upgraded server runtime from .NET Core 3.1 to .NET 7.0. For now, .NET 6.0 binaries are also included with the dedicated server.
• Fixed there being an omega (Ω) in the name of a dll, which prevented the game from working properly in some environments. This also accidentally prevented the game from working if you got it from a particular game pirating service, so uh, you’re welcome, pirates. YAARRRRRR
• All error messages and APIs are now PG-13
• Added a system for updating CustomData in saves when the layout for a component’s CustomData changes between versions
• More kinds of errors in the game loop are now caught and trigger an error screen
• The `PrintUnityEnvironmentInfo` command now reports much more information, especially about the system hardware and the graphics API. The information is also now formatted much more nicely.
• Added command: `runtimeinfo`

• Added OpenGL as an optional graphics API on Windows and MacOS (used with the command-line argument `-force-glcore`)
• Added Vulkan as an optional graphics API on Windows and Linux (used with the command-line argument `-force-vulkan`). Vulkan still has issues on some systems, but once we work those out it will become the default graphics API on Windows & Linux.

• Linux: fixed mouse button presses sometimes registering as phantom scroll wheel events (#146)
• Linux: fixed the camera moving when the game window does not have focus and the cursor moves into the game window area (#148)
• Linux: fixed Action Wheel segments being invisible on Linux OpenGL (#41)
• MacOS: fixed keybindings in the UI sometimes displaying as empty/blank

• Changed default offline player names from “Citizen ” to “Bobby #”, and reduced the max size of the random numbers
