PhysicsJoint

public PhysicsJoint(PhysicsRigidBody nodeA,
 PhysicsRigidBody nodeB,
 Vector3f pivotA,
 Vector3f pivotB)

Parameters:

nodeA - the body for the A end (not null, alias created)

nodeB - the body for the B end (not null, alias created)

pivotA - local translation of the joint connection point in node A

pivotB - local translation of the joint connection point in node B
