hi jayjay and thanks for responding.
im afraid its a little more complicated than that.
i guess i wasnt making enough sense lol.
its hard to explain what im trying to achieve, but consider the sprite 1 as a sort of paint and sprite 2 as a part of environment. now, sprite 2 can be pretty much anything, not just one color block, but fully textured piece of environment, set as any possible angle and shape. problem comes because i want to make background environments and objects on layers behind the actual playing area/layer. so basically id like to paint the actual playing area with all kinds of sprites, while still having nice detailed background.
if im not making sense i can make a better picture to illustrate the masking effect in question <img src="smileys/smiley36.gif" border="0" align="middle">
heres a better example of what im trying to do. cant really get any more specific than that :D
oh and feel free to bask in my incredible artistic awesomeness <img src="smileys/smiley36.gif" border="0" align="middle">
