Help Apply random movement on scene start.

I have multiple ropes with their respected particle attachment. When scene start i want to show random movement like rope hanging on scene start.

There's many ways you can do this, without a more detailed description it's hard to pick the best one. The most basic/easiest one probably being giving a random start rotation to each rope. See:

My rope is affected by gravity so on start applying rotation wont do anything. How can i apply random force for one frame so it would look like rope done some movement for couple of seconds? would it be with simple rigidbody and force?
edit: i tried that and didnt affect at all upto force in +y direction multiplied by 5000.

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.
