I've been interested in rope physics recently—I've successfully implemented a simple Verlet rope with moveable ends. Now I am trying something a little different: I want to start by recreating the mechanic from the game Sky Tourist (video here):
I assume Sky Tourist uses Verlet integration for its rope, but it also has the main character sliding along the rope as a moving weight. How can I recreate that?
Is it just done by applying different gravity to where the character is? Also, how is the collision detection handled between the character and the rope? If the game uses a physics engine like Box2D, how does it make it play nice with the rope, considering it's not a part of the Box2d world?
