I want to make a progress bar made of text! I have two images: One with the text in gray, the other coloured:
As my game is loading, I want the letters to "fill up" with color:
They would start out gray, then fill in.
I was thinking of overlaying a transparent rectangle over the gray image, then stretching the transparent rectangle to match the progress. But then the background will be coloured too. I want only the letters to be coloured!
How can I do this?
