I've heard about API before but haven't used or needed it to this point. But now, as I run into animation transparent gifs, I've fallen victim to the dreaded "Flicker" (lol). Now I'm looking over Pino's API tutorial for beginners and I'm still having problems. First off, what does the mask do? I know that it is a black image of the actual image (in my case a sprite for my game) with a white background, while the actual image has a black background? Does this always have to be like that? And does it matter what format I save the images as? I've been saving as Gif to this point. Thanks in advance. I'll post problems as they occur with API, but this is all that comes to mind at the moment .
