- Designed specifically for 2D video games.
- Circle, convex polygon, and beveled line segment collision primitives.
- Multiple collision primitives can be attached to a single rigid body.
- Fast broad phase collision detection by using a bounding box tree with great temporal coherence or a spatial hash.
- Extremely fast impulse solving by utilizing Erin Catto's contact persistence algorithm.
- Supports sleeping objects that have come to rest to reduce the CPU load.
- Support for collision event callbacks based on user definable object types types.
- Flexible collision filtering system with layers, exclusion groups and callbacks.
- Can be used to create all sorts of effects like one way platforms or buoyancy areas. (Examples included)
- Supports point, segment (raycasting), shape and bounding box queries to the collision detection system.
- Collision forces can be retrieved for gameplay effects.
- Large variety of joints - easily make vehicles, ragdolls, and more
- Joint callbacks.
- Can be used to easily implement breakable or animated joints. (Examples included)
- Maintains a contact graph of all colliding objects.
- Lightweight C99 implementation with no external dependencies outside of the Std. C library.
- Many language bindings available.
- Simple, read the documentation and see!
- Unrestrictive MIT license
