Updating actor transforms in a grab end callback has unpredictable results

[in2dair]

On grab end, attempts to adjust the transform of the actor firing the grab end within the grab end handler are intermittently unreliable. Adding an artificial delay -- dispatching those transform adjustments in a setTimeout -- seems to improve the reliability of transform updates.

someActor.onGrab('end', () => setTimeout(() => {
    // mess with someActor parent and transform
    someActor.parent = this.somOtherActor;
    someActor.transform.local.position = Vector3.Zero();
    someActor.transform.local.position = somePosition.clone();
    someActor.transform.local.rotation = Quaternion.Zero();
    someActor.transform.local.rotation = Quaternion.Identity();
}, 0.2 /*shouldn't have to do this delay!*/));
