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)

- Collision queries (raycasting, region tests)
- Time scaling (slow-mo, speed-up)
- Canvas renderer (supports vectors and textures)
- MatterTools for creating, testing and debugging worlds

- 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 and Yarn using:
npm install matter-js
Alternatively you can download a stable release or try the latest experimental alpha build (master) and include the script in your web page:
<script src="matter.js" type="text/javascript"></script>
Performance with other tools (e.g. Webpack, Vue etc.)
Bundlers and frameworks may reduce real-time performance when using their default configs, especially in development modes.
When using Webpack, the default sourcemap config can have a large impact, for a solution see issue.
When using Vue.js, watchers can have a large impact, for a solution see issue.
Usage
Visit the Getting started wiki page for a minimal usage example which should work in both browsers and Node.js.
Also see the Running and Rendering wiki pages, which show how to use your own game and rendering loops.
Tutorials
See the list of tutorials.
Examples
See the examples directory which contains the source for all demos.
There are even more examples on codepen.
Plugins
The engine can be extended through plugins, see these resources:
Documentation
See the API Documentation and the wiki
Building and Contributing
To build you must first install node.js and pnpm, then run
pnpm install
This will install the required build dependencies, then run
pnpm run start
to spawn a development server. For information on contributing see CONTRIBUTING.md.
