[quote="newt":3uq9sdhl]Why don't you just crop the circle?[/quote:3uq9sdhl]
I need the huge square to mask the rest of the screen. I don't want to see anything except for what's behind the circle. if I crop the circle, it won't hide the background. here I posted a cap to show the problem:
move around sprite3, so you can see what I mean. I want the pink square to only be revealed by the circle. I realize I could've made sprite three bigger, but that's what I'm trying to avoid. if I would have cropped it, it really wouldn't work at all. this cap also let's you see how distracting and difficult it is to move around an invisible mask with a huge border. I plan to have many on screen at once to create a variety of effects.
