- Open
PhysicsKinematic.javaagain and make it implement thePhysicsTickListenerinterface.public class PhysicsKinematic extends SimpleApplication implements PhysicsCollisionListener, PhysicsTickListener {…} - The interface requires you to implement two methods:
prePhysicsTick()andphysicsTick(). Use theprePhysicsTick()method to apply a pushing force on the ball when the platform reaches the top floor.public void prePhysicsTick(PhysicsSpace space, float tpf) { if (isBallOnPlatform && isPlatformOnTop) { ballPhy.applyImpulse(new Vector3f(2, 0, 0), ...
