So i'm having a tiny bit of trouble adjusting to as3. i cant seem to call functions written on the root timeline from any nested movie clips.

for example:

on frame1 of the root timeline i write a simple function:

function greet(){
trace("hello");
}

i then create a movie clip and put it on the stage. on its first frame i call the previous function like so:

root.greet()

but instead of getting traced "hello" i get this compile error:

1061: Call to a possibly undefined method changeActiveFrame through a reference with static type flash.display:DisplayObject.

now, i somewhat understand whats going on, but i have no idea how to fix it. searching for this specific error yields a bunch of unrelated flex problems.

any help would be wonderful, thanks!

hello. i was struggling with the same thing and found an example that works. the code is posted below along with the link to the original post. i also attached the zip file of the working example.

Main swf--------
import flash.events.Event;
import flash.display.Loader;
import flash.net.URLRequest;

var loader:Loader = new Loader();

// find out when Loader has COMPLETEd and INITed (1st frame initialized)
loader.contentLoaderInfo.addEventListener(Event.INIT, loaderInitHandler);
loader.load(new URLRequest("Slides.swf"));

addChild(loader);

function loaderInitHandler(event:Event):void
{
// Access the "_root" timeline of the loaded swf with..
trace(loader.content);

// remember we've told the Events to bubble
loader.content.addEventListener("gotoNextSlide", gotoNextSlideHandler);
loader.content.addEventListener("gotoPrevSlide", gotoPrevSlideHandler);
}

function gotoNextSlideHandler(event:Event):void
{
var mainTimeline:MovieClip = MovieClip(loader.content);
mainTimeline.gotoAndStop(mainTimeline.currentFrame+1);
}

function gotoPrevSlideHandler(event:Event):void
{
var mainTimeline:MovieClip = MovieClip(loader.content);
mainTimeline.gotoAndStop(mainTimeline.currentFrame-1);
}


Nested swf --------
1st frame in file

import flash.events.MouseEvent;

stop();

nextBtn.addEventListener(MouseEvent.CLICK, nextBtnClickHandler);

function nextBtnClickHandler(event:MouseEvent):void
{
// notice I've set "bubble" to false, because we will be listening
// directly to the main timeline in which this function is defined and ran
dispatchEvent(new Event("gotoNextSlide", false));
}

3rd frame in file

import flash.events.MouseEvent;

prevBtn.addEventListener(MouseEvent.CLICK, prevBtnClickHandler);

function prevBtnClickHandler(event:MouseEvent):void
{
dispatchEvent(new Event("gotoNextSlide", false));
}

there is no "root", a MovieClip has a stage property, just call movieclip.stage.myfunction
