Hey all,
Thanks for all the insights!
Sounds like you are trying to extend an instance of a MovieClip...
Yes, this mistake did creep into my thinking a bit-- thanks for
getting me back on track!
I'm trying to create code such that a graphic designer can hand me a
movieClip and I can slap a class on it to define behavior integral to
the movieClip ("extends MovieClip"). An instance of the movieClip
would then instantiate the class, with the possibility of passing
arguments to the constructor. I'd also like to use multiple
inheritence, but I think I can work around that by using sub-classes:
private var type1handler;
private var type2handler;
function blah( type1:String, type2:String ) {
switch(type1) {
case a: type1handler = new <class1_a>
case b: type1handler = new <class1_b>
}
switch(type2) {
case a: type2handler = new <class2_a>
case b: type2handler = new <class2_b>
}
}

class MyMenu extends MovieClip
{
var m_btnButton1:MovieClip; // or a derived-MovieClip class;
// I created a class for
buttons, for example
function init()
{
m_btnButton1.onRelease = function ()
{
// handle release here
}
}
}
Hmm... interesting thought... invert the thinking somewhat:
class superblah {
public var blah:MovieClip;
function superblah() {
blah = create and attach designer movieClip;
blah.onRelease = function...
}
}

Do you mean that setting the associated AS 2.0 class in the
MovieClip's linkage settings is not an option and you want to alter
the class of an existing MovieClip instance at run-time? It's possible
by utilizing the __proto__ property and reorganizing the prototype
chain.
But your code seems to be not optimal:
1. unnecessary and superfluous to create a wrapper function for each
instance's onRelease handler (it creates as many Function instances
as many blah instance is created)
Agreed it's unnecessary and superfluous, and looking for a better way...
Truthfully, I've never used the AS 2.0 class in the linkage box--
this may be what I was looking for!
Can this be set up so that instances can then pass parameters to the
class's constructor?
mucking with the __proto__ may work as well...
(And your example, of course, is more like what I'd meant:)
2. the same with setting the handler function in the constructor,
since it can be a simple class member
class blah extends MovieClip {
private function onRelease(): Void {
// handle release here
}
}
Thanks again,
--Dave
