I'm trying to draw a few objects to an image, add an effect to it, then paste it over top the screen. Basically I only want the effect to affect certain objects, and not everything the player sees. But as those objects move and I repaste them to the image, it leaves trails behind because the image doesn't get clear. Overall image is a transparent background so that's why I can't just overwrite it with something else. Is there a simple and effective way to just clear an image?
