or heres another alternative to that:
im trying to make it so when you click somewhere on the one side of the screen, it creates a splatter on the opposite side of the screen. so lets say the screen is 550 pixels wide, and I have a line running down the middle at 275. Im trying to make it so that when you click, let's say on the right side somehwere, it creates a splatter on the x opposite of the screen. So if i placed my click at X:276, right next to the middle, the splatter would appear at x:274, the mirror area.
So one way i could do it would be combining the middle line and the splatter on whatever side i clicked, horizontally flipping it, and centering the middle line.
Or so I think. I hope I didn't confuse anyone TOO much.
