Re: [Flashcoders] [as2] problem with super class on Tweener callback
Hello, Cory!
That is a nice one, I believe it would work for now!
Oh, the wonders AS2 forces you to do...
Thanks!

Re: [Flashcoders] [as2] problem with super class on Tweener callback
I don't have a solution, but I have an arguably less ugly workaround
that I've used in similar cases.
public class Superclass {
public function load():Void {
__load();
}
protected function __load():Void {
// "Base class" functionality here
}
}
public class Subclass extends Superclass {
public function load():Void {
Tweener.addTween(this, {onComplete: __load});
}
}

Yeah, I've looked at Tweener's code, even tried to tweak a little bit to see
if I could get through it, then I realized it's not Tweener's fault.
By issuing a:
trace(tScope);
on line 754, right before:
tTweening.onComplete.apply(tScope, tTweening.onCompleteParams);
it traces my current instance correctly.

Yes, I tried that. Just tried again right now to make sure I wasn't missing
anything ;)
Still, no success...
I've just pasted the code from the superclass inside the onComplete handler
(it's just a event dispatch anyway, works for now), but I really hate myself
for doing this, specially because this is a refactoring of some old crappy
code, and it's supposed to be made the right way.
Anyway, still trying to come up with something. (Boy, I really wish the boss
would let me use AS3 already, I'm sure these things wouldn't happen. AS2
really isn't made to serious programming)
Thanks for the help so far, Zeh! Valeu!

Re: [Flashcoders] [as2] problem with super class on Tweener callback
Hello there!
(...)
Well, what that does, in the same situation as above, is that when Tweener
is done, that very own load() function is called again.
I've tried using Delegate, delegating to himself, to the superclass, nothing
did it.
I've also tried creating a local function that just calls super.load() and
delegating to that, but no luck either.
My guess at the moment is that it's a side-effect to the "weird" AS2
implementation of static classes.
However I'm curious. Am I doing something completely wrong and not noticing
it? Is my implementation flawed?
Or there is a way to work that around?
Hm.. that's a good question. It runs functions inside of the instance
using .apply, but if you pass the super.load without wrapping it, I'm
sure exactly how the function reference is handled by actionscript.
Anyway, have you tried this instead?
public function load():Void {
var obj:Object = new Object({
_y: 200,
time: 1,
onComplete: function() { super.load(); }
});
Tweener.addTween(this, obj);
}
I believe your overall implementation is fine.
Zeh

[Flashcoders] [as2] problem with super class on Tweener callback
Hello there!
Here's the deal: I have the following class hierarchy
MovieClip // adobe
- BasicMovieClip // as2lib
-- GenericMovieClip
--- EventMulticasterMovieClip
GenericSection
- DropdownSection // abstract class, private constructor
-- *Several classes extending DropdownSection
That GenericSection is part of a section handling. It has basically two
functions: load() and unload(), both public, and they basically dispatch an
event, so my section handler can act properly.
Ok, so I have several "sections" who behave almost the same, so I'm writing
generic code in DropdownSection, so I can generalize it more cleanly.
Here comes the code:
When I have this on DropdownSection:
public function load():Void
{
super.load();
}
public function unload():Void
{
super.unload();
}
(these are not necessarily needed, but just to clarify)
then everything works perfectly, when my section handler calls load() and
unload() on any of the classes that extends DropdownSection.
However, when I code something like this:
public function load():Void
{
var obj:Object = new Object({
_y: 200,
time: 1,
onComplete: super.load
});
Tweener.addTween(this, obj);
}
(and the equivalent for the unload() function)
* Tweener is Zeh Fernando's tween class - http://code.google.com/p/tweener/
Well, what that does, in the same situation as above, is that when Tweener
is done, that very own load() function is called again.
I've tried using Delegate, delegating to himself, to the superclass, nothing
did it.
I've also tried creating a local function that just calls super.load() and
delegating to that, but no luck either.
My guess at the moment is that it's a side-effect to the "weird" AS2
implementation of static classes.
However I'm curious. Am I doing something completely wrong and not noticing
it? Is my implementation flawed?
Or there is a way to work that around?
Thank you very much for your time!
