Thanks David,
For some odd reason if I do in my coopy
public function init():Void
{
trace("init in copy class");
}
it wont fire but it will fire the init method from the Original Class (which
by the way seem very similar to inheritance :) ).... any ideas why this
could be happening?
Thanks again...

You'd basically create a 'wrapper' method:
class CopyClass {
private var original:OriginalClass;
private var mc:MovieClip;
public function CopyClass(mc:MovieClip)
{
this.mc = mc;
original = new OriginalClass(mc);
}
public function init():Void
{
original.init();
}
}
It's almost like calling super. However, if you're looking to override the
original class' init(), then you don't need to call original.init() and
just
create your logic in your CopyClass' init method. This is the one drawback
to using Composition over Inheritance, but I would say it's worth it in
the
long-run.

Subject: [Flashcoders] Composition access
I am slowly moving from inheritance to composition for a specific project,
one way to "extend" my classes is by creating a copy of them into the new
created classes...
class OriginalClass {
var mc:MovieClip;
function original(mc:MovieClip) {
this.mc = mc;
init();
};
function init() {
trace("original");
}
------ now trying to overwrite init
class CopyClass {
var original : OriginalClass;
var mc : MovieClip;
function CopyClass(mc:MovieClip) {
this.mc = mc;
original = new OriginalClass(mc);
}
//How do I access init from the original class? I know that doing
inheritance I can just declare a new init method in my CopyClass but in
this
case it doesnt work that way.
TIA
