Help Rope connected 3d object and its weight

[kripa1415]

I tried your suggestion. setting stretching scale to 1 and stretchCompliance 0 causing unity to crash. Attached rope creation code snippet. Sometimes its working but extremely slow
frame by frame and rope also not in good shape. Attached video link here.

Code:

private IEnumerator CreateRope(ObiSolver solver, ObiRope rope)
{
    // Create a rope
   
    // Setup a blueprint for the rope:
    var blueprint = ScriptableObject.CreateInstance<ObiRopeBlueprint>();
    blueprint.resolution = 0.65f;
    blueprint.thickness = 0.45f;
    blueprint.pooledParticles = 100;


    Vector3 point = Vector3.zero;
    blueprint.path.Clear();
    int filter = ObiUtils.MakeFilter(ObiUtils.CollideWithEverything, 0);
    float mass = 1;
    for (int i = 0; i < points.Length; i++)
    {
        if (i == 0 || i == points.Length - 1)
            mass = .1f;
        else
            mass = .2f;
         
        if( i == 0 )
        {
            point = rope.transform.InverseTransformPoint(points[i].position);
            blueprint.path.AddControlPoint(point, -Vector3.zero, Vector3.zero, Vector3.up, mass, 0.5f, 1, filter, Color.white, "A");
        }

        Vector3 point2 = rope.transform.InverseTransformPoint(points[i].position);
        Vector3 direction = (point2 - point) * 0.25f;
       
        blueprint.path.AddControlPoint(point2, -direction, direction, Vector3.up, mass, 0.5f, 1, filter, Color.white, points[i].name);
       
       
    }

    blueprint.path.FlushEvents();
    yield return StartCoroutine(blueprint.Generate());

    rope.collisionMaterial = collisionMaterial;
    rope.ropeBlueprint = blueprint;

    // access the distance constraints currently simulated by the solver:
    var solverConstraints = rope.GetConstraintsByType(Oni.ConstraintType.Distance)
                as ObiConstraints<ObiDistanceConstraintsBatch>;
    int batches = solverConstraints.batches.Count;
    for (int k = 0; k < batches; k++)
    {
        int cnt = solverConstraints.batches[k].constraintCount;
        for (int i = 0; i < cnt; i++)
        {
            //solverConstraints.batches[k].restLengths[i] = length;
        }
    }
   
   

    var obiRopeExtrudeRenderer = rope.GetComponent<ObiRopeExtrudedRenderer>();
    // load the default rope section:
    obiRopeExtrudeRenderer.section = Resources.Load<ObiRopeSection>("DefaultRopeSection");
    obiRopeExtrudeRenderer.GetComponent<MeshRenderer>().material = material;
    obiRopeExtrudeRenderer.GetComponent<ObiPathSmoother>().decimation = 0.1f;
    obiRopeExtrudeRenderer.GetComponent<ObiPathSmoother>().smoothing = 3;

    cursor = rope.AddComponent<ObiRopeCursor>();
    cursor.cursorMu = 1;
    cursor.sourceMu = 1;

    obiRopeExtrudeRenderer.uvScale = new Vector2(2, 15);
    obiRopeExtrudeRenderer.thicknessScale = 1.1f;

    rope.distanceConstraintsEnabled = true;
    rope.stretchingScale = 1f;
    rope.stretchCompliance = 0f;
    rope.bendCompliance = .1f;
   

    PinRope(rope, points[0].GetComponent<ObiCollider>(), points[points.Length - 1].GetComponent<ObiCollider>(), new Vector3(0f, 0, 0), new Vector3(0f, 0, 0));

    //RopeAttachment(rope, points[0].GetComponent<ObiCollider>(), points[points.Length - 1].GetComponent<ObiCollider>());

    //AddDistanceConstrants(rope);

}

Code:

private void PinRope(ObiRope rope, ObiCollider bodyA, ObiCollider bodyB, Vector3 offsetA, Vector3 offsetB)
{
   
    // Pin both ends of the rope (this enables two-way interaction between character and rope):
    var pinConstraints = rope.GetConstraintsByType(Oni.ConstraintType.Pin) as ObiConstraints<ObiPinConstraintsBatch>;
    pinConstraints.Clear();
    var batch = new ObiPinConstraintsBatch();
    batch.AddConstraint(rope.solverIndices[0], bodyA, offsetA, Quaternion.identity, 0, 0, float.PositiveInfinity);
    batch.AddConstraint(rope.solverIndices[rope.activeParticleCount - 1], bodyB, offsetB, Quaternion.identity, 0, 0, float.PositiveInfinity);
    batch.activeConstraintCount = 2;
    pinConstraints.AddBatch(batch);
    rope.SetConstraintsDirty(Oni.ConstraintType.Pin);
