Add simple arithmetic methods to structs

Questions & Answers

I would have something like

public struct WorldPosition{
     public int x, y;
}

public void Start(){
     WorldPosition p = new WorldPosition(0,1) * 5f + new WorldPositon(5,-5);
}

Like vectors in fact.

Not sure I understand the question. Are you trying to do this?

public void Start(){
  Vector2 p = new Vector2(0,1) * 5f + new Vector2(5,-5);

}
