does the compiler optimize code like declarations in loops? seems lines 6, 7 are taken care of by what Dante/Zack told me before, to not worry about. Then what about redundant if statements inside my foreach loop lines 14, 15, which are only intended for initialization only. I bet THAT is wasteful, that the compiler wouldn't remove that. The com…

	void Update(){

		//find furthest apart X, Y
		//adjust camera accordingly

		Vector2 max;
