So, as I understand it, a distance joint acts as a "pole" between two objects, allowing neither to move any further or closer then the distance between the two objects at the creation of the joint.
I am trying to get only a piece of this functionality. I am creating a fishing game, and I have a hook that I want to attach to a bobber. What I want is a rope, not a pole. The hook can get closer to the bobber, but not farther away.
Is there a way to do this?
