@Nab1929(View Post) Basically, you're saying "us eletronix soemhaw", very explicative. And no, that's not what he meant. What he meant is how does he make a screen that if you spark a button a thing on the screen travels down it.
As for the screen, just copy/paste jacksonmj's epic screen. It works really well, and why reinvent the wheel? If you want to create one yourself, just break apart his one and see what it does, then replicate.
