Help Replace pin constraint in runtime?

[Karlanton]

I have a rope and at both ends there is a pin constraint to two different objects. After a 'event' i would like one of the pin constraints to be attached to a new object. How do i do this? i tried copying the code from the Grappling hook scene by doing this:

Thanks in advance for any help!

Hi there,

You can remove the old constraint, then add a new one that uses the new object just like you are doing. However you must pass the index of a constraint to RemoveConstraint(), not the index of a particle. (i.e. If you only have one pin constraint added, you should pass "0" as the index).

Did this now. The pin constraint does get removed but the rope is still attached to the first object that had the pin constraint from the beginning and no new pin constraints were added to the last particle. I was not sure what to pass in the rope.addsolver(?) so i tried both with null and the pinconstraint. Where am i doing it wrong haha?

With this code the pin constraint gets removed from the seleted particle in the "edit particle" tab.

However, the rope is still attached to the gameobject. why is that?

They seem to have the same issue as i do.

You must remove the constraints component (constraints.RemoveFromSolver(null)) from the solver and re-add them (constraints.AddToSolver(null)) after. If you just remove, add or modify constraints while they're in the solver, the changes won't be pushed to the solver. Please read the docs:
