Class HeightfieldCollisionShape

java.lang.Object
com.jme3.bullet.collision.shapes.CollisionShape
com.jme3.bullet.collision.shapes.HeightfieldCollisionShape
All Implemented Interfaces:
com.jme3.export.Savable
public class HeightfieldCollisionShape extends CollisionShape
Uses Bullet Physics Heightfield terrain collision system. This is MUCH faster than using a regular mesh. There are a couple tricks though: -No rotation or translation is supported. -The collision bbox must be centered around 0,0,0 with the height above and below the y-axis being equal on either side. If not, the whole collision box is shifted vertically and things don't collide as they should.
