I have a kinematic rigid body (body A) that I move in a script forward and backward, along a platform. A separate rigid body is attached to body A with a hinge joint. I can move body A and body B follows as expected. however, if I change the anchor of the hinge at runtime, shouldn't the hinged body move along? It does not, and in fact the hinge anchor doesn't seem to have any effect. Any ideas on what is going on ?
