Detect Collision between rope and collider

[Kifwat]

I have 3 ropes in my scene, all of them inside one Obisolver, and they collide with the ground and also some walls. I want to make a condition that return true when all those ropes didn't collide with any wall (but still colliding with the ground), I tried the script below but it didn't work properly, I mean the condition return false even a rope is still colliding with the wall, I think it's because there's 3 ropes in the same ObiSolver, how can I solve this please?

Code:

void Solver_OnCollision(object sender, Obi.ObiSolver.ObiCollisionEventArgs e)
   {
       frame = e;

       for (int i = 0; i < e.contacts.Count; ++i)
       {
           if (e.contacts.Data[i].distance < 0.1f)
           {
               Component thecollider;
               if (ObiColliderBase.idToCollider.TryGetValue(e.contacts.Data[i].other, out thecollider))
               {

                   if (thecollider.CompareTag("Wall"))
                   {
                       TouchingWall = true;
                   }
                   else
                   {
                       TouchingWall = false;
                   }

               }
           }
       }
