Box2D

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
