In more than one rope, it is not seen which ropes are in contact with each other. I have multiple ropes under the one solver.

Rope1 and Rope2 colliding but , Pa and Pb gives same Rope(Rope 1) , same blueprint ( not saying other interacted rope) . but it doesn't say which of the two interacting rope is which. how can i learn each of the collided rope

Quote:The ParticleInActor struct has two public variables:

Actor: A reference to the ObiActor to which this particle belongs. //<--- this is what you need
IndexInActor: The index of this particle in the actor's arrays.

Quote:ObiSolver.ParticleInActor pa = solver.particleToActor[particleIndex];
ObiSolver.ParticleInActor pb = solver.particleToActor[particleIndex];

ObiRope ropeA = pa.actor as ObiRope;
ObiRope ropeB = pb.actor as ObiRope;

if (ropeA == ropeB)
  // self-collision
else
  // inter-collision

You'll find the answer in the manual, in the "Retrieving the actor involved in a contact" section of "Scripting collisions":

So you can just access pa and pb's actor property to get a reference to the ropes. For instance:
