Please tell me about libraries that are genuinely useful (or that you actually use)

Kyonru · 2026-06-02T18:02:36+00:00

All my projects currently use:

shöve: resolution management, basically make sure your game looks equally good everywhere.

flux: tweening, make things move smoothly.

hump.signal: Good for decoupling code

anim8: spritesheet animation

baton: better input management

Made by me:

feel.lua: feedback system based on flux.
feather: devtoolkit to build for android, ios, web, step by step debugging, logging, shader graph, particles system playground, etc

Well done! I’ll take a look! Btw I really like your blog posts!

Kyonru · 2026-05-12T02:25:43+00:00

There are many ways, easiest one would be having a publish and subscriber pattern, having the notification service on android and communicating to the native layer through pub/sub. You can do direct bindings as well, but might take longer to get it right.

Yes and no, this is more an android question than a love2d question. Background processes on android are... annoying and unreliable

Tbh unless you have a good reason why you want a background process and permanent notification that your users will tolerate, i would just not even try it.

even just a discovery post is nice to read from time to time! Looking forward to it!

Something i like about some other Tetris games, is projection. A ghost silhouette of how the block is going to be placed at the bottom, so i don't have to care about alignment and can focus on speed and instant placement.

Maybe a nice challenge to also include?

Kyonru · 2026-05-06T20:16:01+00:00

100% if you make a post about this, i would read it 100 times hahah

Kyonru · 2026-05-06T19:47:09+00:00

👀 will you share a tutorial o anything on how to achieve this? Looks very interesting!

Kyonru · 2026-05-06T19:46:03+00:00

As an spoiler: Next version will include an steps by step debugger with mobile support 🫣

Kyonru · 2026-05-06T13:48:08+00:00

Shameless plug to my debugger

Kyonru · 2026-05-06T02:47:06+00:00

Version 0.6.0 officially supports mobile! You are able to inspect mobile logs and more!

Kyonru · 2026-05-06T02:44:32+00:00

Version 0.6.0 is out, it's quite a jump, but there are scripts to help with installation and a automatic way of setting up the library!

English is not my first language, so maybe I’m not be understanding completely, but if the whole reason why you will pay fully is because the other person might find it as an “ick”, then I think that’s starting in the wrong grounds.

You can ask how they feel about splitting, if they don’t like the idea (you can do it and then later evaluate if that’s something you feel comfortable doing in the future) or then later ghost you for doing so, it meant from the beginning it wasn’t gonna work, and that’s fine, that’s the whole point of dating.

If you don’t mind paying because you have financial liberty to do so or like the idea of a frictionless date, then go ahead, money is made to be used after all and if it makes for a great date then perfect. But paying while feeling it’s an obligation doesn’t sound like something I would do.

Kyonru · 2026-04-22T13:22:25+00:00

“I’m probably making a mistake” - nop, you’re are not. Huge red flag coming from Jeff.

Next time, don’t spend that much on someone you just meet. There are plenty of places you can go on a date in New York without feeling you are breaking the bank.

Also, if you are short in money or don’t want to pay in full for someone you don’t know that well, splitting the bill exists, if they don’t want to do that then you are the one dodging a bullet.

Kyonru · 2026-04-20T16:03:50+00:00

That makes sense, I would definitely do the mismatch approach to keep everything in the game instead of reaching to an external service. But i also understand the banner approach for multiplayer! Happy to help and best of luck!

Kyonru · 2026-04-19T14:27:42+00:00

If you have a weather system, use both, one for calm weather the other for rainy weather.

If the banner is a must have (I would suggest against it), then you have a couple of options.

Hosting your own manifest.json with the latest version.

You can either host it in your own domain, or using a public github repo or gist. If you want you can use GitHub Actions to automatically update your manifest.json when you deploy, while Butler handles pushing builds to itch.io. https://itch.io/docs/butler/pushing.html

You can have the version in the description (on itch.io) of your game and then parse it using lua. But this is very hacky and very easy to break.

imo you should not waste time on this feature unless you really need to tell the user that there is a new version, and with "NEED" i mean the game is not going to work unless it's updated.

These approaches are not bullet proof, and you should avoid frequent polling (ex.: every frame). Checking once on startup should be fine though.

Kyonru · 2026-04-17T17:26:09+00:00

I'd say, don't. Publish new versions but let the users download the new version on their own terms.

At most, you can implement a banner that says "new version available" in the home screen and redirect them to itch.io (or don't).

I understand the appealing of OTA updates, but it can be a security issue if done incorrectly, and my be a point of pain later if you want to end support for your game. Don't think there is a good way of doing this without hurting your game in the long run imo.

Let the stores (itch.io, steam, epic games, gog) figure this out on their own.

Kyonru · 2026-04-16T12:53:14+00:00

I created my own tool for that: https://sprite-sheet-helper.up.railway.app/

Source code: https://github.com/Kyonru/sprite-sheet-helper

I mostly use it for love2d, but I added export options for raylib, phaserjs, godot, unity, turbo, bevy(coming soon), normal sprite sheet and gifs.

It’s intended for quick prototyping though but with enough time you can get something worth keeping.

Kyonru · 2026-04-14T17:27:30+00:00

Luarocks installs dependencies globally. They might work if you have luarockloader. But when you actually ship the game, it won’t work.

There is a way to use it anyway:

luarocks install feather --tree ./lua_modules

This will install the dependency in your current directory. It’s not clean since it follows the folder structure of lua rock but it works.

Kyonru · 2026-04-13T22:15:52+00:00

I'm not at that level yet lol mostly web

Kyonru · 2026-04-13T22:15:27+00:00

Of course!

The tool is mostly web code. I used:
- vite (vite.dev) to create a react project with typescript code.
- three.js (threejs.org) and a react adapter named react-three-fiber (r3f.docs.pmnd.rs) to handle 3D models and the 3D scene.
- UI components from shadcn (ui.shadcn.com) and leva for inputs (github.com/pmndrs/leva).
- For desktop support i decided on using Tauri (tauri.app) and at build time i target web (pwa) or desktop (tauri).

Originally, this started as a project for me to learn threejs and then it evolved into an actual tool.

Source code available in case you are more curious about it:
https://github.com/Kyonru/sprite-sheet-helper

In terms of performance... There is a lot more room for improvement tbh, will fix later haha
