There are several ways to make delay functions in as3.0.

1. using EnterFrame(delay time depends on frame rate)

var count:Number = 0;
var delay:Number = 45;
this.addEventListener(Event.ENTER_FRAME, onenterframe);
function onenterframe(e:Event) {
  count++;
  if (count == delay) {
    this.removeEventListener(Event.ENTER_FRAME, onenterframe);
    trace("delay happenes");
  }
}

2. using Timer

var timer:Timer = new Timer(1500);
timer.start();
timer.addEventListener(TimerEvent.TIMER, onTimer);
function onTimer(e:TimerEvent) {
trace("delay happenes");
timer.removeEventListener(TimerEvent.TIMER, onTimer);
}

3. THE SIMPLEST: setTimeout

var timeId = setTimeout(completeHandler, 1500);
clearTimeout(timeId);
function completeHandler(){
trace("delay happenes");
}
