Hello! I am developing a game together with my friends. If you have a 360-pad, you can play it here:

Anyhow, the player controls a walker thing with two legs, and each analog stick controls each leg. Right now, an invisible rigid body is attached via a configurable joint to the body of the walker. This invisible rigid body has the foot attached to it with a hinge joint, allowing it to rotate. The actual leg is purely visual, and is stretched between the foot and the body.
Now, I want the leg to interact with other things in the physics engine. I tried simply attaching colliders to the leg, though that created jerky behaviour. Adding a rigidbody did not help either. I suspect that you must somehow control these colliders with velocities, not simply setting their position depending on the location of the foot.
So, my question is then: How do you construct this kind of legs in a correct way, in order for the legs to work as proper physical entities, and making them stretch nicely?
