### Features

- Rigid bodies
- Compound bodies
- Composite bodies
- Concave and convex hulls
- Physical properties (mass, area, density etc.)
- Restitution (elastic and inelastic collisions)
- Collisions (broad-phase, mid-phase and narrow-phase)
- Stable stacking and resting
- Conservation of momentum
- Friction and resistance
- Events
- Constraints
- Gravity
- Sleeping and static bodies
- Plugins
- Rounded corners (chamfering)
- Views (translate, zoom)
- Collision queries (raycasting, region tests)
- Time scaling (slow-mo, speed-up)
- Canvas renderer (supports vectors and textures)
- [MatterTools](https://github.com/liabru/matter-tools) for creating, testing and debugging worlds
- World state serialisation (requires [resurrect.js](https://github.com/skeeto/resurrect-js))
- Cross-browser and Node.js support (Chrome, Firefox, Safari, IE8+)
- Mobile-compatible (touch, responsive)
- An original JavaScript physics implementation (not a port)

### Install

You can install using package managers [npm](https://www.npmjs.org/package/matter-js) and [Yarn](https://yarnpkg.com/) using:

    npm install matter-js

Alternatively you can download a [stable release](https://github.com/liabru/matter-js/tags) or try the latest experimental [alpha build](https://github.com/liabru/matter-js/tree/master/build) (master) and include the script in your web page:

    <script src="matter.js" type="text/javascript"></script>

### Usage

Visit the [Getting started](https://github.com/liabru/matter-js/wiki/Getting-started) wiki page for a minimal usage example which should work in both browsers and Node.js.  
Also see the [Running](https://github.com/liabru/matter-js/wiki/Running) and [Rendering](https://github.com/liabru/matter-js/wiki/Rendering) wiki pages, which show how to use your own game and rendering loops.

### Tutorials

See the list of [tutorials](https://github.com/liabru/matter-js/wiki/Tutorials).

### Examples

See the [examples](https://github.com/liabru/matter-js/tree/master/examples) directory which contains the source for all [demos](#demos).  
There are even more examples on [codepen](http://codepen.io/collection/Fuagy/).

### Plugins

The engine can be extended through plugins, see these resources:
