The current bounding box of the shape.
The rigid body_ this collision shape is attached to.
Collision type of this shape used when picking collision handlers.
User definable data pointer. Generally this points to your the game object class so you can access it when given a cpShape reference in a callback.
Coefficient of restitution. (elasticity)
Group of this shape. Shapes in the same group don't collide.
Sensor flag. Sensor shapes call collision callbacks but don't produce collisions.
Surface velocity used when solving for friction.
Coefficient of friction.
Opaque collision shape struct.
