Package com.jme3.bullet.collision.shapes

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 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)
