Releasing softbody particles from anchor

[blobman]

Thanks for your reply. For now we found a workaround using the Teleport method on the softbody. Will let you know if we try the anchor method again!

FYI: I don't think this bug got patched:

Had to manually patch it in Obi Softbody 6.5.1

Okay. The teleport work around seem work yesterday. However today, I'm running into index out of bounds at a different line:

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 <b6c5d0f08ddf477186f780f49bb14dee>:0)
Obi.ObiSoftbody.Teleport (UnityEngine.Vector3 position, UnityEngine.Quaternion rotation) (at Assets/Obi/Scripts/Softbody/Actors/ObiSoftbody.cs:198)
ModelAPI.Teleport (UnityEngine.Vector3 position) (at Assets/Scripts/Model/API.cs:22)
API.Start () (at Assets/Scripts/API.cs:86)

Code at Assets/Obi/Scripts/Softbody/Actors/ObiSoftbody.cs:198:

Code:

        public override void Teleport(Vector3 position, Quaternion rotation)
        {
            base.Teleport(position, rotation);

            if (!isLoaded)
                return;

            Matrix4x4 offset = solver.transform.worldToLocalMatrix *
                               Matrix4x4.TRS(position, Quaternion.identity, Vector3.one) *
                               Matrix4x4.TRS(Vector3.zero, rotation, Vector3.one) *
                               Matrix4x4.TRS(Vector3.zero, Quaternion.Inverse(transform.rotation), Vector3.one) *
                               Matrix4x4.TRS(-transform.position, Quaternion.identity, Vector3.one) *
                               solver.transform.localToWorldMatrix;

            Quaternion rotOffset = offset.rotation;

            var ac = GetConstraintsByType(Oni.ConstraintType.ShapeMatching) as ObiConstraints<ObiShapeMatchingConstraintsBatch>;
            var sc = solver.GetConstraintsByType(Oni.ConstraintType.ShapeMatching) as ObiConstraints<ObiShapeMatchingConstraintsBatch>;

            // rotate clusters accordingly:
            for (int i = 0; i < ac.GetBatchCount(); ++i)
            {
                int batchOffset = solverBatchOffsets[(int)Oni.ConstraintType.ShapeMatching][i]; // Line 198

                for (int j = 0; j < ac.batches[i].activeConstraintCount; ++j)
                {
                    sc.batches[i].orientations[batchOffset + j] = rotOffset * sc.batches[i].orientations[batchOffset + j];  // http://obi.virtualmethodstudio.com/forum/thread-3742-post-13810.html#pid13810
                }
            }

        }

Tried setting rotation to `Quaternion.identity` or rotation on the model's transform.

Update:
Teleport method seems to work when I invoke in `Update`, but does not in `Start`. So perhaps there is some softbody initialize at runtime I need to watch out for?

Update2: 
Perhaps the issue is here:

Code:

        public override void LoadBlueprint(ObiSolver solver)
        {
            base.LoadBlueprint(solver);
            RecalculateCenterShape();
            SetSelfCollisions(m_SelfCollisions);
        }

Where the softbody actor is set to loaded after running `base.LoadBlueprint(solver);` but needs to run `RecalculateCenterShape();` to be fully loaded?

Update3: 
Found the issue. It's due to application not yet playing ... so have to wait until that flag is flipped!
