Help Re-enabling a rope solver makes the rope go crazy

[josemendez]

when I turn a solver back on, the rope connected to it acts like it just got hit with a massive amount of physical force and goes flying around, before coming to a rest where it originally was when I first turned the solver off. Is there a way to make it not do this? I want it to not move or react at all when I turn the solver back on.

Hi,

You mention a rigidbody is suspended from the rope. If you disable the solver, the rope will cease applying any forces to the rigidbody and it will fall to the ground. When you re-enable the solver the rigidbody will apply an enormous force to the rope (since it is probably down below, far past the rest length of the rope) and this will make the rope go "crazy" for a few seconds.

If you disable the solver or the rope, you need to disable any rigidbodies interacting with it too. Otherwise when you re-enable the rope, other objects might have moved far from the intended position/state and the solver will have to apply very large forces to both the rope and the rigidbodies to try and get them back into place.

let me know if you need further help. cheers!
