The rigid-body physics engine for the unfinished game 'KFighter'.
It's written from scratch in C++ but it may as well be in C since it uses so few of C++ features. It's currently Windows only but it's designed to be extended to other platforms in the future. I started it by following a tutorial by the brilliant Casey Muratori. The physics engine is based off talks done by Erin Catto of Box2D fame and works by iteratively solving a set of constraints.
- Collision detection and resolution
- Rectangle collision
- Friction
- Collision islands (collections of objects typically connected by joints or other constraints that shouldn't collide with each other)
- Multiple collision points
- Stable stacking
- Joints
- Angle constraints
- Joint friction
- PID controlled motors
- Loop live code editing
- Pose matching
