Phyz

Phyz is a work-in-progress physics engine for 2D games, written in Zig. Goals are simplicity, speed and ease of use, in that order.

Non-goals

To keep the engine simple and fast, a number of things are purposefully not supported:

• Rotation and angular velocity
• Soft bodies
• Non-convex colliders (can be approximated using multiple convex colliders)
• Multiple colliders per object (can be approximated using constraints)

If you need support for these things, I recommend using a more complex physics engine such as Chipmunk2D or Box2D.
