Package com.jme3.bullet.collision

Interface ContactListener

All Known Subinterfaces:
ContactManager
All Known Implementing Classes:
DefaultContactManager, 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.

    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 Details

    • 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)
