Help Detect specific rope collision.

Oh, I missed that one. However, the outcome is still the same. FPS drop happens and the game becomes unplayable. This is the code: 

Code:

public class RopeCollision : MonoBehaviour
{
    private ObiSolver _solver;

    private ObiSolver.ObiCollisionEventArgs _collisionEvent;

    private void Awake()
    {
        _solver = GetComponent<ObiSolver>();
    }

    private void OnEnable ()
    {
        _solver.OnParticleCollision += Solver_OnParticleCollision;
    }

    private void OnDisable()
    {
        _solver.OnParticleCollision -= Solver_OnParticleCollision;
    }

    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 theCollider = world.colliderHandles[contact.other].owner;
                if (theCollider)
                {
                    print(theCollider.name);
                }
            }
        }
    }
}

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.
