Function Documentation

float32 b2MixFriction ( float32  friction1, float32  friction2  )

inline

Friction mixing law. The idea is to allow either fixture to drive the restitution to zero. For example, anything slides on ice.

Definition at line 37 of file b2Contact.h.

float32 b2MixRestitution ( float32  restitution1, float32  restitution2  )

inline

Restitution mixing law. The idea is allow for anything to bounce off an inelastic surface. For example, a superball bounces on anything.
