PhysicsGhostObject (jMonkeyEngine3)

java.lang.Object
- com.jme3.bullet.collision.PhysicsCollisionObject
- - com.jme3.bullet.objects.PhysicsGhostObject

All Implemented Interfaces:

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.
