"_root.onLoad" replacement in AS3?

[Oldsage10]

Does anybody know the replacement for the AS2 _root. level method

_root.onLoad = function(){
// Do Stuff //
}

In AS3, I tried

function displayOpeningMessage (event:Event):void{
trace(openingMessage)
}

stage.addEventListener(Event.COMPLETE, displayOpeningMessage);

And "openingMessage" is a String which otherwise appears when running a trace(); This above code does nothing when I test the .swf

As far as I'm aware you don't need it, nor do you need it in AS2, except when loading a MovieClip. If you just put code on the timeline it will execute in the same manor as if it was in an onLoad function. If you want to use it when a MovieClip is loaded on to the stage you can give the class a constructor function.

Oh, ok... It's just that I wanted to organize it in a function... But I found a work-around, just put it in an ENTER_FRAME, and then within the function, remove the EventListener...

Look into using a document class. The constructor of the document class will fire exactly once, when the .swf is loaded. You can also fill the document class with functions that apply to the scope of the .swf file as a whole (like pausing a game for example)

you can do that too, no need for an enter_frame. just put this on the first frame.

function init():void
{
//stuff goes here
}

init();

if you're worried about the first frame being revisited, you can use a boolean to make sure that init can only get called once ever.

Thanks Afro, I'm trying to slowly move over to AS3, so I've gotta learn this kind of stuff!
