HTML5 JavaScript 2D 物理引擎：Matter.js

Matter.js是一款采用JavaScript編寫的2D剛體物理引擎。

var Bodies = Matter.Bodies;
var Engine = Matter.Engine;
var engine = Engine.create(container, options);
var World = Matter.World;

World.addBody(engine.world, Bodies.rectangle(300, 180, 700, 20, { isStatic: true, angle: Math.PI * 0.06 }));
World.addBody(enigne.world, Bodies.rectangle(300, 70, 40, 40, { friction: 0.001 }));</pre>

特性：


Physical properties (mass, area, density etc.)

Rigid bodies of any convex polygon

Stable stacking and resting

Restitution (elastic and inelastic collisions)

Conservation of momentum

Friction and resistance

Constraints

Gravity

Composite bodies

Sleeping and static bodies

Original JavaScript physics implementation (not a port)

HTML5 canvas renderer

Mobile-compatible (touch, scaleable)

Cross-browser (chrome, firefox, IE8+)

World state serialisation (requires resurrect.js)

Built in GUI for testing (requires dat.gui.js)

Time scaling (slow-mo, speed-up)

Broad-phase, mid-phase and narrow-phase collisions
</ul>
