public bool swapBodies ;

설명

If enabled, the two connected rigidbodies will be swapped, as if the joint was attached to the other body.

Prior to Unity 3.4, this was wrongfully applied to all ConfigurableJoints with the configuredInWorldSpace/ property set. If you want to restore the behaviour of older Unity versions and you are using configuredInWorldSpace, enable this property.
