Hi,
I just want to ask for a code for actionscript3 in making a button that's ON CLICK, ANIMATES ONE OF THE OTHER BUTTONS ON STAGE ON CLICK AGAIN, STOPS THE ANIMATION OF THE BUTTON BEING ANIMATED.

tnx
That's actually pretty easy. You just use a Boolean Variable, toggle its value, and execute codes accordingly [my_btn = your button | animation_mc = movieclip with animation]:

Actionscript Code:
import flash.events.MouseEvent;

var playVar:Boolean = false;
animation_mc.stop();

my_btn.addEventListener(MouseEvent.CLICK, toggleAnimation);

function toggleAnimation(e:MouseEvent){
    playVar = !playVar;
    if(playVar == true){
        animation_mc.play();
    } else {
        animation_mc.stop();
    }
}

Hope this helps
