Function Documentation
◆ b2MixFriction()
|
inline |
Friction mixing law. The idea is to allow either fixture to drive the friction to zero. For example, anything slides on ice.
Definition at line 42 of file b2_contact.h.
◆ b2MixRestitution()
|
inline |
Restitution mixing law. The idea is allow for anything to bounce off an inelastic surface. For example, a superball bounces on anything.
Definition at line 49 of file b2_contact.h.
◆ b2MixRestitutionThreshold()
|
inline |
Restitution mixing law. This picks the lowest value.
Definition at line 55 of file b2_contact.h.
