I imagine you're calling clearInterval with the appropriate interval ID upon

Sorry, I'm a newbie too but it seems to be a good practice to specify
clearly the scope you refer to.
It's clearly specified in chapter 6 to be aware about the scope.

As the coffee kicks in, that also looks like Composition, not Singleton.
Like, you have a Singleton class instantiating instances and returning them
of other classes from within itself.

The Idea of a getInstance method (Singleton), as you guys have been saying,

Just in case someone's wonders; creating a Singleton is nothing new in
ActionScript, it can be done in AS1, AS2 or AS3.

In AS1, I would write this a bit like that:
MyClass = function () {
this.someProperty = whatever;
}
MyClass.instance = null;
MyClass.getInstance = function () {
if(myClass.instance == null) {
MyClass.instance = new MyClass();
}
return MyClass.instance;
}
Well, actually there is a difference.
In AS3, class constructors can not be Private. In AS2 they can.
So in AS2 you can do this:
class MySingleton {
private function MySingleton() {
}
public static function getInstance() {
// bah blah..
}
}
Which is not allowed in AS3.

Muzak
Woah, I never noticed you can private your constructor!! Lol

I had an idea. Not sure if it's a good one.
Flash is pretty good with optimizing all local var names to shorter ones
like _1 and _2 which does make decompiled code a bit tougher to read.
What if I took it just a step further and in one or two of my main
classes I added something like this:
The idea is to use it (this) when you have two variables with the same
name, usually to distinguish between the class member and a locally
declared variable. You must know that :) The compiler won't know to
use this or not in those cases, so it is important to use it in those
contexts.
The thought of changing multiple lines of code to go from static to non

this can also be used to refer an instance's member variable explicitly.
Since scoping rules allow for a local variable (in a method) to be named the
same as an instance member variable, this is required to differentiate
between the two.
