Help Detect specific rope collision.

Well, you're writing the collider name to console once per contact, no wonder performance goes down the drain  . Writing to the console is extremely slow.
Remove the print() line and it should run acceptably fast.

Edit: also, you're using the second index of the contact (which for particle-particle contacts, is a particle index) to access the collider handles array, which will result in an out of bounds exception.

I wasn't paying attention to the documentation, I believe. I wasn't being careful, because I thought it would work like CollisionStay callback but I forgot that I am actually calling for a particle collision which is very expensive considering that I have over 4000 particles on the scene  This code actually does what I want: 

Code:

private void Solver_OnParticleCollision(object sender, ObiSolver.ObiCollisionEventArgs e)
    {
        var world = ObiColliderWorld.GetInstance();
        foreach (var contact in e.contacts)
        {
            // this one is an actual collision:
            if (contact.distance < 0.01)
            {
                var pa = _solver.particleToActor[contact.particle];
                var po = _solver.particleToActor[contact.other];
                if (pa.actor.gameObject != po.actor.gameObject)
                {
                    Debug.Log(pa.actor.gameObject.name + " collides with: " + po.actor.gameObject.name);
                }
            }
        }
    }

I can now receive an information about who collides with whom. Therefore, I can now detect when a rope is colliding with another one and I can use it to expand the gameplay further. Thank you for putting out the obvious that I was missing out .
