Help  Need fixed width rope with no stretching at all

Think about what would happen in real life if you attached one end of the rope to a iron wall, the other end to a iron sphere (both absolutely immobile), then pushed an infinitely rigid iron bar across the rope with infinite force: the wall, the sphere and the bar can neither move or deform. So the only possible outcome is the rope breaking, no matter how strong.

Static colliders in all physics engines extern “infinite” force. Or rather, they don’t care about forces or physics of any kind. They just move to wherever you tell them to move, no matter if they’re colliding with other stuff.

You need to use rigidbodies and move them with forces, to give ropes and other objects a chance of pushing back and resist stretching.

I’d recommend familiarizing yourself with colliders/rigidbodies/forces/inertia/mass, etc before attempting to use Obi. There are the basic foundation of any physics stuff, otherwise you’re in for a very frustrating experience.

Thanks Jose. Will read more about all you suggest. Cheers!
