Hi Mendelshon,
You shouldn't use a singleton to take off, just use that main document
class to take of !
The main Document class is automatically your main stage as a MovieClip
- Displayobject.
That is always a static class and is a Singleton by itself I gues
becuase you only van have 1 stage :)
So if you want to reference that stage from a display-child of that
Documentclass( extends Sprite/MovieClip):
than from within that child call this.root.stage ; but this is not
used most of the time and you can't call functions in the main through
that ref.
When you add childs to it that need a reference to the main
Documentclass, just pass a reference to them when they are created.
like
package
{
import flash.display.MovieClip;
import flash.display.Stage;
import flash.display.StageAlign;
import flash.display.StageScaleMode;
[SWF( backgroundColor='0x454545', frameRate='30', width='471',
height='505')]
public class Main extends Sprite
{
private var app: MyApplication;
public function Main():void
{
app= new MyApplication(this); //here you create a child
from class MyApplication (which extends a Sprite or MC) , argument this
= reference to the main class
addChild(app)
}
}
that way you can start leafing.
If you don't want to overcomplicate and have a central point to put some
function stuff it isn't that bad to make MyApllication a Singleton which
you can easily reference.
That doesn't imply that you are advised too :)
If your app's start growing and you are adapted to AS3,take a look at
PureMVC for example or start playing with events (in AS3 you can extend
the Event Class en pass additional parameters).
Good Luck
Latcho

Hmm...I'm not sure what you mean by static class. Are you saying that
the other classes I instance via composition in my singleton should
themselves be static?
- MM
Why aren't you using a static class for that instead of a Singleton?

Thanks for the responses everyone.
Steven, I could use some constructive feedback:
Usually what I do is have a singleton instanced when the swf is
initialized, and using composition, other classes are instanced within
the singleton. So the singleton becomes a sort of tree trunk with
everything branching off of it. How would you say that this is a bad
idea? It's worked well for me. What would be a more effective
alternative to structuring my swfs?
