Re: [Flashcoders] Re: Programmatically instantiating a class thatextends MovieClip
There's a really light class called Prototype which is free to download at
http://codext.com/code/9. It does the same thing except with full
constructor support. It also has a really simple/clean API:
mc = createEmptyMovieClip(mc, 1);
Prototype.makeInstanceof(mc, MyMovieClipClass);
thats it! I've loved it ... works on extending other elements too, like
TextFields or _root (I use that one constantly).

Then use in your code:

As a variant on the __proto__ method (which I gather is what
the compiler actually uses behind the scenes anyway) I also
bundle the code into a static method
Class A {
...
// dynamicMc (no library symbol) will be added and subclassed
to mcSubClass
dynamicMc:MovieClip = McSubClass.addInstance(baseMC);
}
class McSubClass extends MovieClip{
function McSubClass {
//empty constructor
}
function init(){
//initialize mc - add dynamic graphics etc
}
static function addInstance (base_mc) {
var newMc;
var nd = base_mc.getNextHighestDepth();
newMc= base_mc.createEmptyMovieClip(mcSubClass+nd,nd);
newMc.__proto__ = new McSubClass ();
newMc.init();
return newMc;
}
}
maybe mc.__proto__ == MyClass.prototype (below) is better
than my newMc.__proto__ = new McSubClass ()
my method (i picked up on this list) does have the side
effect that the constructor can't initialize the mc, hence
the separate init call after the __proto__ / constructor; all
wrapped in one method so I don't forget

Hello :)
it's easy, you must use __proto__
AS2 - MyClass extend MovieClip !!!
MyClass extends MovieClip {
// o Constructor
public function MyClass() {
}
}
var mc = createEmptyMovieClip(myInstance, 1) ;
mc.__proto__ == MyClass.prototype ;
MyClass.call(mc) ;
EKA + :)

That's exactly what I mean. As a result you can do cool
things like
reparenting -- like moving a button from one window to another. It
handles the MovieClip creation itself.
A code example really isn't too easy, because the framework that
allows this to be possible is quite large. If you were really
interested, you could look at the code. Here's a link:

It's a gigantic class...so it might be difficult to work through.
The
important method is createMovieClips(), which is called
when a view
(the type of object that encapsulates movieclips) moves to a new
superview.

this
way, then create movieclips on the fly. It's very nice
to work with.
So you never really subclass movieclip, you use
composition instead.
