Class GhostObject

java.lang.Object
  com.bulletphysics.collision.dispatch.CollisionObject
      com.bulletphysics.collision.dispatch.GhostObject

Direct Known Subclasses:

PairCachingGhostObject

public class GhostObject
extends CollisionObject

GhostObject can keep track of all objects that are overlapping. By default, this overlap is based on the AABB. This is useful for creating a character controller, collision sensors/triggers, explosions etc.
