In the case of a rope attached to a kinematic rigidbody, this means the rope won't be able to prevent rigidbody movement once it's tensed up. Instead, the rigidbody will pull from it with infinite force. This will not only undo any knots in the rope, but also allow it to stretch indefinitely.
If you want the rope to be able to act upon the manipulator, you need to keep the manipulator non-kinematic and move it around using forces/accelerations.
I'm sorry to bother you again .
I've tried turning the manipulators non-kinematic, but unfortunately, since I'm working on the expansion of an existing simulator, this is causing me many problems. Is there, by any chance, some workaround to keep kinematic manipulators?
Actually, my goal is to replicate the movements of the pliers in the first video with the manipulators, so the students may train on that actions. I don't need to keep the rope in that position, but just to "close" the knot, so I'm thinking: is it possible to freeze a rope section or substitute it at run time (even with an input with the controller) with another one? Because in that case, maybe I could use a closed-loop blueprint to give the feedback a correctly done exercise.
