I need help with animation. How do you animate where when you hold down a button, it animates. But when you let go it stops? (Just saying I know nothing on how to animate at all)

IF !BUTTON(0) THEN SPSTOP controlNumber should work. Although when I tried that it really messed up future animations...

Especially if you want to clip it. You should've put that in.

Can I have some help with normal animating/ preparing to animate?

Changing to a new frame is pretty easy but the simplest way I've found uses a bit more code than it used to. If FU and FV are the first frame UV coordinates, and EV and EU are the second, 'SPANIM controlN,"UV",-delay,FU,FV,1,EU,EV,-delay,EU,EV,1,FU,FV' will play a two-framed animation.
