LittleJS is a super lightweight 2D JavaScript game engine with fast WebGL rendering. It is designed to be small, simple, and easy to use for various applications, from game jams to commercial releases. This engine has everything necessary to make high-quality games, including fast rendering, physics, particles, sound effects, music, keyboard/mouse/gamepad input handling, update/render loop, and debug tools. It is recommended that you start by copying the LittleJS Starter Project This file is mostly empty with just a few things you can use to get started or remove. You can also download and include engine.all.js or engine.all.min.js. In order to load files like images you will need to run a small web server like http-server on npm. I recommend an editor that does this for me automatically like Brackets or VS Code with the Live Server plugin.
Features
- Very small footprint with no dependencies
- Can update and render 10,000+ objects at 60fps, often many times more
- Object oriented system with fast 2D physics and collision handling for axis aligned boxes
- Positional audio effects with zzfx and music with zzfxm, mp3s, or wavs
