LittleJS Box2D Physics Plugin
- Box2dObject extends EngineObject with Box2D physics
- Call box2dInit() to enable
- You will also need to include box2d.wasm.js
- Uses a super fast web assembly port of Box2D v2.3.1
- More info: https://github.com/kripken/box2d.js
- Functions to create polygon, circle, and edge shapes
- Contact begin and end callbacks
- Wraps b2Vec2 type to/from Vector2
- Raycasting and querying
- Box2dTileLayer for grid based collision
- Every type of joint
- Debug physics drawing
- Box2D works per second: its velocities and accelerations are in units per second, and it reads the engine's gravity as units per second squared, where an EngineObject's are per frame
