I was curious as to how to flick overlays?

Like whenever I attack, it'll flick the "attack" state, but not on the overlay. How is this done?
I'm not sure this is possible, but why not remove a few overlays, add the attack one, then re-add the ones you removed.
When you flick("state",src) You flick the atom and its overlays. Pay attention. I believe that only doing this with overlays either involves having the atom in it's default icon_state and just flicking an icon_state that it doesn't have but it's overlay does. That or just add and remove overlays.
