Help Rope not colliding with itself

[josemendez]

Hi Marat,

If you're using a rope cursor to extend the length of the rope, there's a known bug that will deactivate self-collisions between newly created particles. Fortunately the fix is easy. Open the ObiRope.cs file, and add this right at the end of the RebuildConstraintsFromElements() method:

Code:

RecalculateRestPositions();

Should look like this:

    //<...more stuff here...>
               loopClosingBatch.restBends[0] = 0;
               loopClosingBatch.bendingStiffnesses[0] = new Vector2(_maxBending, _bendCompliance);
               loopClosingBatch.ActivateConstraint(0);
           }

           RecalculateRestPositions();

       }// end of RebuildConstraintsFromElements.

Note that the cost of a rope increases with its length. Depending on what your use case is, a particle-based simulator like Obi might be a bad choice. Alternatives exist that, while much more limited, allow to have arbitrarily long cables/ropes with constant cost.
