Relative 2D overlay (CopperCube Extension)

This is a very basic yet super helpful extension when working with 2D overlays in Coppercube. This extension does nothing special but simply change the position mode of 2D overlays during runtime from "absolute (pixels)" to "relative (percentage)", I have seen so many games, even the one that has been created by some advanced user, they all have the issue of overlays.

This will solve your issues, make sure you always develop your game with overlays in "Absolute (pixels)" mode and attach this behavior to the overlay, and it will solve the issue of dynamic overlays, that is when your game resolution changes or if the window size is changed.
