How to 'reset' physics constraints

Hi there,

I have an actor with two meshes and a physics constraint. The physics constraints has locked linear movement, and allows some orientation freedom. Sometimes I need to manually change the relative position (distance) between the meshes, but obviously the physics constraint pulls them back into their old position/distances. Does anyone know how to overcome this? I imagine something like disabling the constraints, manually updating position, and then re-enabling the constraint so that it takes the new positions/distance as the default. But I don’t see a way of disabling or enabling constraints, or resetting them or something. I asked about ‘break constraint’ on the answerhub, but as usual nobody answers :frowning:

Thanks!

No idea AT ALL? Sometimes I feel like there is absolutely no one who really understands how unreal engine works…

One thing you can do is enable motor on constrain and change its target. I have controls of Aerosled setup just like that. Angular motor keeps steering ski strength, when I need to turn them I just change motor’s target and constrain will turn them.
Can you be more specific of what you want to achieve?

As far as I remember you can “enable and disable” them by changing their settings but you need to wait for physics update for each setting to have effect.

Yeah I suppose the motor idea could work, if I would set up high values for the spring in the linear motor. thanks!
