C# Class Box2D.Dynamics.Contacts.Contact

The class manages contact between two shapes. A contact exists for each overlapping AABB in the broad-phase (except if filtered). Therefore a contact object may exist that has no contact points.

Méthodes publiques

Méthode	Description
Evaluate ( Manifold manifold, Transform xfA, Transform xfB ) : void
GetWorldManifold ( WorldManifold worldManifold ) : void	Get the world manifold.
Init ( Fixture fA, int indexA, Fixture fB, int indexB ) : void	initialization for pooling
MixFriction ( float friction1, float friction2 ) : float	Friction mixing law. The idea is to allow either fixture to drive the restitution to zero. For example, anything slides on ice.
MixRestitution ( float restitution1, float restitution2 ) : float	Restitution mixing law. The idea is allow for anything to bounce off an inelastic surface. For example, a superball bounces on anything.
ResetFriction ( ) : void
ResetRestitution ( ) : void
SetFlagForFiltering ( ) : void	Flag this contact for filtering. Filtering will occur the next time step.
Update ( IContactListener listener ) : void
