Class CollisionShape

java.lang.Object

com.jme3.bullet.collision.shapes.CollisionShape

All Implemented Interfaces:

Savable

Direct Known Subclasses:

BoxCollisionShape, CapsuleCollisionShape, CompoundCollisionShape, ConeCollisionShape, CylinderCollisionShape, GImpactCollisionShape, HeightfieldCollisionShape, HullCollisionShape, MeshCollisionShape, PlaneCollisionShape, SimplexCollisionShape, SphereCollisionShape

public abstract class CollisionShape
extends java.lang.Object
implements Savable

This Object holds information about a jbullet CollisionShape to be able to reuse CollisionShapes (as suggested in bullet manuals) TODO: add static methods to create shapes from nodes (like jbullet-jme constructor)
