Help Apply random movement on scene start.

[josemendez]

My rope is affected by gravity so on start applying rotation wont do anything.

I meant before placing the rope under a solver, after you start the simulation rotation won't do anything indeed. If you start the scene with everything already under a solver it will start simulating immediately.

Using rigidbody.AddForce on a rope won't do anything, as Obi does not use rigidbodies at all, that's the whole point of a particle based engine. You'll need to apply forces to the particles themselves, see:

So simplest thing you could do is set initial velocities for all particles in each rope.
