Looking at an old post here.

I want something similar to that, but instead of expanding, I want the load bar to shrink.

I am creating a graphical, animated loading bar, but I want to give the impression it is expanding whenever the game is loading. So What I have done is, made the actual graphic of the bar a separate layer. The one that is going to be shrinking is a solid color similar to the color of the background.

I thought about instead of shrinking it, maybe move the position of the solid bar forward until at the position that I need it to be, but that always ends up making it go off the screen.

Any help would be appreciated.
