Help Get the rope REAL particle index on colliision

[lacasrac]

I have this oncollision code:

private void Solver_OnCollision(ObiSolver s, ObiSolver.ObiCollisionEventArgs e)
{
    var world = ObiColliderWorld.GetInstance();
    foreach (var contact in e.contacts)
    {
        if (contact.distance < 0.025f)
        {
            var collision = world.colliderHandles[contact.bodyB].owner;
...

            var particleIndex = solver.simplices[contact.bodyA];
            var contactedRope = (ObiRope)solver.particleToActor[particleIndex].actor;

and after

private int GetParticleNeighborIndex(int particleIndex, int offset)
{
    var solverIndex = rope.solverIndices[particleIndex];
    var elementCount = rope.elements.Count;
    int index;

    var e = 0;
    for (; e < elementCount; ++e)
        if (rope.elements[e].particle1 == solverIndex)
            break;

    if (e == elementCount - 1 && offset > 0)
        index = rope.elements[e].particle2;
    else
    {
        var n = Mathf.Clamp(e + offset, 0, elementCount - 1);
        index = rope.elements[n].particle1;
    }

    if (index > _lastParticleIndex && offset > 0) index = _lastParticleIndex;

    return index;
}

But as soon as I have 2 ropes in the same Solver, I get a crash:

IndexOutOfRangeException: Index was outside the bounds of the array.
 CreateClimbableObiRope2D.GetParticleNeighborIndex (System.Int32 particleIndex, System.Int32 offset) (at Assets/KLGames/ClimbObiRope/Scripts/CreateClimbableObiRope2D.cs:699)

What is the probleme here?


the crash is in this line


var solverIndex = rope.solverIndices[particleIndex];

IndexOutOfRangeException: Index was outside the bounds of the array.
(particleIndex is 130 but the solverIndices.length is only 87)

How can get back the REAL PARTICLE INDEX?

Thanks
