Execute functions in document class when main timeline reaches a frame

Question

Hi,
I have 3 functions in my main document class that I want to execute when the main timeline reaches a particular frame number.
how do I do that?
see the code and comments
public function mainClass()
//stage declaraction
stage.align = StageAlign.TOP_LEFT;
stage.scaleMode = StageScaleMode.NO_SCALE;
stage.addEventListener(Event.RESIZE, stageResized);
//wrap these next 3 lines in an if statement that says if maintimeline currentframe = x
position();
loadXml();
initArrowButtons();
slideTimer = new Timer(timer_delay);
slideTimer.addEventListener(TimerEvent.TIMER, nextSlide);

Answer 1

It's still undocumented, but something like this would do it:
package
    import flash.display.MovieClip;
    public class FrameScript extends MovieClip
        public function FrameScript()
            addFrameScript( 3, frameFour );
        private function frameFour():void
            trace( "you have reached Frame 4" );
You can test this as a documentclass.
