Class SoftBodyWorldInfo

java.lang.Object

com.jme3.bullet.NativePhysicsObject

com.jme3.bullet.SoftBodyWorldInfo

All Implemented Interfaces:

java.lang.Comparable<NativePhysicsObject>

public class SoftBodyWorldInfo
extends NativePhysicsObject

Physics-simulation parameters that can be customized for each PhysicsSoftBody, based on Bullet's btSoftBodyWorldInfo.

NOTE: When a PhysicsSoftBody is added to a PhysicsSoftSpace, it acquires the SoftBodyWorldInfo of that space. To customize a body, assign it a new info after adding it to the space.
