Disabling child scaling, when parent scales with Math

Question

I think this code is only simple math, but I'm posting it, because almost everyone fakes the scaling with unparenting, then parenting again.

Vector3 originalParentScale = new Vector3;
Vector3 originalScale = new Vector3;
void Awake(){
    originalScale = transform.localScale;
    originalParentScale = transform.parent.localScale;
}
void Update(){
    transform.localScale = (originalParentScale / transform.parent.localScale) * originalScale;
}

I think it can be even improved, so I would be happy if someone can improve it. It's challenge too, so happy programming :-)

Answer 1

I'm not very familiar with Unity3D, but are you absolutely 100% certain that transform.parent.localScale will never be 0? Otherwise, you should check for that before dividing.
