Okay, here's the drill.
I have a MovieClip — call it FooA — that's been linked to an AS2
class — call it FooA_Class — (that extends MovieClip and does lots of
other useful things.)
In that MovieClip, I have another MovieClip — SubFooA — that's been
exported and given a proper instance name. In FooA_Class there's an
instance variable that has the same name as the instance name for
SubFooA (that idiom is weird, but okay..)
I would like to, in ActionScript, dynamically instantiate and render
onto the stage several instances of FooA — it's a MovieClip, after
all — it has some visual things in itself, like colored blocks and
stuff.
Now, I want to also, in ActionScript, call a bunch of the useful
methods that FooA_Class has.
What's the idiom for doing such a thing??
I've tried what the Java guy in me says to, like instantiate FooA and
do things with it:
var mFooA:FooA = new FooA();
mFooA.doSomeMethod();
But, now I can't get it on the stage properly, even with various
incarnations of attachMovie in either the constructor of FooA, or
right there after the constructor (registerClass/attachMovie)
Then I try this confusing idiom:
Object.registerClass("mFooA", FooA);
_root.attachMovie("FooA", "FooA", 1);
The MovieClip FooA appears on the stage, but that's it — I can't call
useful methods on it as I have no proper handle to the instance.
If I do this:
Object.registerClass("mFooA", FooA);
var aObject:Object = _root.attachMovie("FooA", "FooA", 1);
what is returned from attachMovie isn't properly cast to my class
type — which is a bit odd. I mean, if I do this:
Object.registerClass("mFooA", FooA);
var aObject:FooA_Class = _root.attachMovie("FooA", "FooA", 1);
Flash complains — whatever the equivalent of a class cast error it
spouts..type mismatch or something?
So, the basic question is this: how can I programmatically
instantiate and deliver to the stage a movie clip linked to my own
custom class (which extends MovieClip) and then actually call the
useful methods contained within that linked custom class?
This _has_ to be easy, no?
