Package com.jme3.bullet.objects

Class PhysicsGhostObject

java.lang.Object
com.jme3.bullet.collision.PhysicsCollisionObject
com.jme3.bullet.objects.PhysicsGhostObject
All Implemented Interfaces:
com.jme3.export.Savable
Direct Known Subclasses:
GhostControl
public class PhysicsGhostObject extends PhysicsCollisionObject
From Bullet manual:
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.
