class simvx.core.physics._material.PhysicsMaterial

Surface properties for physics bodies.

Attributes: friction: Coefficient of friction [0..1]. Higher = more grip. restitution: Coefficient of restitution [0..1]. 1 = perfectly elastic bounce. density: Mass per unit volume. Used for auto-computing mass from shape volume.
