The current distance between the RopeConstraint's two Attachment.
The maximum distance two Attachment can be when connected with a RopeConstraint. Measured in studs.
Restitution controls how elastic an Attachment connected by a RopeConstraint will be when reaching the end of the rope RopeConstraint.Length. The value of this property is constrained between 0 and 1.
A RopeConstraint with a Restitution of 0 will not bounce when its Attachments reach their maximum separation.
A RopeConstraint with a Restitution of 1 will be almost completely elastic when its Attachments reach their maximum separation.
