LittleJS now does 2D and 3D! 🚂🎉 The same tiny, fast, open source JavaScript engine. Now with a full 3D renderer in the same canvas as your 2D game, level editors built in, a particle effects library, a faster core, and tools for making games with AI. frankforce.com/littlejs-is-...

It's Small! The whole engine, with 3D, Box2D physics and sound, is about 150 KB gzipped. A bundled 2D game ships at about 26 KB, a lit 3D scene at 47 KB. Most engines this complete are a megabyte or more.

Integrated Level Editors The level editor is built into the engine now, in 2D and 3D. Press Escape while your game runs, edit the level in place with undo, autosave and prefabs, press Escape again and keep playing. Then make it an editor for your game: github.com/KilledByAPix...

Easy Particle Effects One line of code: particleEffect('fire', pos). Fire, smoke, sparks, explosions, rain and more, in 2D or 3D, each with scale, hue and saturation. Tweak them or build your own in the designer: killedbyapixel.github.io/LittleJS/exa...

Sunset Islands 🌅 www.dwitter.net/d/32957 this gif is a tiny tropical paradise with code so tiny it fits in a tweet! it has a sunset with distant islands and water reflections. i sometimes view of my work as a magic trick for programming and math.

javacript code published 12/18/2024 for(n=i=2e3;i--;x.fillRect(i,Y,-30,5))n+=S(n)*97,Y=i**4*t%1080,g=(Y-700)**2<n,s=Y<700,d=Math.hypot(i-960,s?Y-440:i**5%400),x.fillStyle=`hsl(${d<129?60:s?Y/5+g*29-79:309-Y/8} 99%${99-d/16-g*49}%`

you can make a voxel mining game with procedural textures in only about 100 lines of code using LittleJS. this is one of the short examples that comes with the engine.

Made a quick trailer for GoYomi, my free 9×9 Go trainer with an AI coach. New since last time: select "Their idea" to see what your opponent is planning, and you can play by keyboard or by ear with a screen reader. ▶ killedbyapixel.github.io/GoYomi

My new game Reversiology is out! Learn Reversi by playing, with a coach that grades every move. Free in your browser ▶ killedbyapixel.github.io/Reversiology

Don't let the friendly coach fool you. The top level is stronger than any human! It reads 22 moves ahead, plays the last 22 perfectly, and holds its own against Edax, one of the strongest Reversi programs. 🧠

The part I use most: hints when I'm stuck, and "their idea", which shows what the AI is planning to do to me. You can take back any move and try something else. There are 156 puzzles from real games too. 🚀

My new game Reversiology is out! Learn Reversi by playing, with a coach that grades every move. Free in your browser ▶ killedbyapixel.github.io/Reversiology

I made this because I wanted to get better at Reversi but had no idea what I was doing wrong. So the coach grades each move and tells you why, in plain words. Here it is catching me giving away a corner. 👍

It wasn't easy and I had to help solve some of the tougher bugs and weird graphical glitches we saw along the way. Everything is running smooth now!

The first boot was barely 11 fps. So we replaced the stock GL layer with a custom PowerVR renderer and did some other optimizations to get it to a solid 60 fps in the Flycast emulator.

I've seen some cool stuff made by Claude so I wanted to try an AI-assisted retro port. This game was the perfect candidate: small, self contained, everything procedural. So I let Claude hammer on it, rewriting it in C++ and testing it against the original.
