hello,

i would like to know how to make a button to be used once only. for example, i made a button and it'll add score when i press it. i only want it to score once, but since i used a on(release), so it'll continue to add score when i keep clicking it. is there a way to make it happen once only?
here is the actionscrpit that i'm using.

on (release) {
_root.score += 100;
}

please help me!
