Yan can simply scale by position on X or Y
But you would have to coincide it with your level/layout background.
For instance, you have a layout level where you can walk down the street, and the view goes a bit up into the depth ...
if you used X,Y in the top left (0,0) as origin, the you could simply rely on the Y-axis, and base a small formula on how hgh up on the Y axis the image is and scale accodingly (or size)
