Help Resetting Rope causing Error

[vrtraining]

Hi,

This is my old code that I got from this forum to reset the rope back to its original state.

Code:

float initialLength = 0.88f
ObiRopeCursor ropeCursor;
ObiRope rope;

public void ResetRope()
    {
        rope.RemoveFromSolver();
        rope.ClearState();
        rope.AddToSolver();
        ropeCursor.ChangeLength(initialLength);
    }

Now since the new update has changed the ChangeLength() method my new code becomes.

Code:

public void ResetRope()
    {
        rope.RemoveFromSolver();
        rope.ClearState();
        rope.AddToSolver();
        ropeCursor.ChangeLength(initialLength - rope.restLength);
    }

But its causing error, rope disappears and I get

Code:

ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
System.Collections.Generic.List`1[T].get_Item (System.Int32 index) (at <bae5e84a08394aad9eb61062d3ccb3ca>:0)

Obi.ObiSolver.LateUpdate () (at Assets/Obi/Scripts/Common/Solver/ObiSolver.cs:1163)

If I remove 

Code:

rope.RemoveFromSolver();
rope.ClearState();
rope.AddToSolver();

Then error goes away but I dont get starting initial state like before
