Ok, here's where I stand.
I have a picturebox with my sprite in it - picSprite
I have a picturebox with the mask in it - picMask
I have a picturebox to store the background in once it's tiled - picTiled
I have a picturebox to do my work in - picBuff
and then I have the final picturebox - picMain

I had some code to put the tiled map onto the buffer, then BitBlt the sprite on, and then copy it all to the main pic, but for some reason nothing would happen, so I just got rid of all the code, cause I tried many different things to fix it, but nothing. Any help people?
