Interface ContactListener

All Known Implementing Classes:

DeformableSpace, MultiBodySpace, PhysicsSoftSpace, PhysicsSpace

public interface ContactListener

Interface to receive immediate notifications when 2 collision objects come into contact.

Bullet implements persistent contacts, so manifold IDs and point IDs are sometimes reused from step to step.

Method Summary

Modifier and Type	Method and Description
void	onContactEnded(long manifoldId) Invoked immediately after a contact manifold is removed.
void	onContactProcessed(PhysicsCollisionObject pcoA, PhysicsCollisionObject pcoB, long manifoldPointId) Invoked immediately after a contact point is refreshed without being removed.
void	onContactStarted(long manifoldId) Invoked immediately after a contact manifold is created.

Method Detail

onContactEnded

void onContactEnded(long manifoldId)

Invoked immediately after a contact manifold is removed.

Parameters:

manifoldId - the native ID of the btPersistentManifold (not zero)

onContactProcessed

void onContactProcessed(PhysicsCollisionObject pcoA,
                        PhysicsCollisionObject pcoB,
                        long manifoldPointId)

Invoked immediately after a contact point is refreshed without being removed. Skipped for Sphere-Sphere contacts.

Parameters:

pcoA - the first involved object (not null)

pcoB - the 2nd involved object (not null)

manifoldPointId - the native ID of the btManifoldPoint (not zero)

onContactStarted

void onContactStarted(long manifoldId)

Invoked immediately after a contact manifold is created.

Parameters:

manifoldId - the native ID of the btPersistentManifold (not zero)
