A rope joint enforces a maximum distance between two points on two bodies. It has no other effect.
Warning: if you attempt to change the maximum length during the simulation you will get some non-physical behavior.
A model that would allow you to dynamically modify the length would have some sponginess, so I chose not to implement it that way. See b2.DistanceJoint if you want to dynamically control length.
