Class ConeJoint

java.lang.Object

com.jme3.bullet.joints.PhysicsJoint

com.jme3.bullet.joints.ConeJoint

All Implemented Interfaces:

Savable

public class ConeJoint
extends PhysicsJoint

From bullet manual:
To create ragdolls, the cone twist constraint is very useful for limbs like the upper arm. It is a special point to point constraint that adds cone and twist axis limits. The x-axis serves as twist axis.
