[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!

Hm.. that's a good question. It runs functions inside of the instance

sure exactly how the function reference is handled by actionscript.
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.
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);
}
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
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});
}
}

Re: [Flashcoders] Re: AS2 vs. AS3: instantiate library symbols with a loop string concatenation
Hi Jonathon,
Your AS2 method is tried and true. Here's the new and improved AS3 way
of doing it.
for (var i:Number = 0; i 30; i ++) {
// build the String name
var symbol:String = sym + i;
// locate the class
var symbolClass:Class = getDefinitionByName(symbol) as Class;
// instantiate the clip using the class
var new_mc:MovieClip = new symbolClass() as MovieClip;
// add clip to stage
addChild(new_mc);
// do stuff with clip
}
You may or may not need the as MovieClip bit on the instantiation,
depending on how your class is actually defined.
hth,
Bob

Re: [Flashcoders] Hit Object Question
I think it's a typo but your BdrRep has no rectangle drawn, and even if
you did have the rectangle, toggling the alpha of Sprite underneath will
not give you any visual feedbacks...

Re: [Flashcoders] Hit Object Question
To make your approach work, you can draw a rectangle in ldrBdr and
bdrRep (one in red and one in green) and toggle the alpha of one of them
sits above the other (if you addChild() it goes above everything already
in the display list).
Or just change the colour of one border Sprite instead.

I think it's a typo but your BdrRep has no rectangle drawn, and even if

not give you any visual feedbacks...

Hi all
I am trying to implement hit object in my project. I have sprite
class and I
am loading multiple instances of UI Loader in my sprite class and
displaying
it on the main screen. The user can drag and drop those UILoaders
on the
main stage wherever they want.My aim was that if user drops one
UIloader on
top of already placed UiLoader, then the already placed UILoader
will be
replaced with the dropped UILoader. I am successful in
implementing that by
hitting hitTestObject method. All of my UIloaders are having
green color
border. Now my requirement is that as soon as the user places
UILoader on
top of already existing UILoader , the UILoader which is going to be
replaced changes border color from green to red showing the user
that the
UIloader is being replaced and on Mouse release the UiLoader is
going to be
replaced.
In short on mouse over, the border color has to be changed and on
mouse
release, object has to be replaced. I am adding my rectangle(in
Sprite
Container) as the border to the UILoader. Below is some code to
make things
little clearer
Please help me in figuring out the problem.
Any help will be appreciated.
Thanks

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!

Hm.. that's a good question. It runs functions inside of the instance

sure exactly how the function reference is handled by actionscript.
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.
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);
}
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] positioning along bezier curve
Hello Keith is there a way to calculate a point midway along the curve? private function findPointOnCurve(p1x:Number, p1y:Number, cx:Number, - this method can return midway along the curve if bezier curve is symmetrical only. finding point on curve by time iterator is very different thing than finding point by distance along the curve. It is difficult calculation using bisection of Newton algorithm: http://bezier.googlecode.com/svn/trunk/bezier/src/flash/geom/Bezier.as look at getTimeByDistance possible way using Bezier class: var myBezier:Bezier = new Bezier(.); var midwayTime:Number = myBezier.getTimeByDistance(myBezier.length/2); var midwayPoint:Point = myBezier.getPoint(midwayTime); also analog of findPointOnCurve is presented in Bezier class as getPoint method. good luck! -- iv http://www.bezier.ru http://bezier.googlecode.com ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] Re: AS2 vs. AS3: instantiate library symbols with a loop string concatenation
Thanks to everyone who chimed in with the answer!
Seems like there is a little disagreement between getDefinitionByName and
getClassByName.
From some basic searches it looks like getClassByName has been replaced by
getDefinitionByName, and I could only find
flash.utils.getDefinitionByNamein the Adobe LiveDocs.
Either way, thanks for those who helped - I didn't quite know where to loock
in my trusty moock.

Imagine I have in my library a series of MovieClips with linkage

sym0

sym29
In AS2, if I wanted to create instances of each one (or perhaps
decide
which symbol to use based on XML data, for example), I could use a
for loop:
for (var i:Number = 0; i 30; i ++) {
var new_mc:MovieClip = parent_mc.attachMovie(sym + i, sym +
i, i);
// do stuff with clip
}
and create each symbol via passing a concatenated string as
symbolName.
Now, in AS3, I can't think of a way to do this efficiently. In our
simple
example, I can only think of the following:
for (var i:int = 0; i 30; i ++) {
var sym:MovieClip;
switch (i) {
case 0: sym = new sym0();
case 1:sym = new sym1();
case 2: sym =new sym2();
...
}
// do stuff with clip
}
Is there a more efficient way to do this in AS3? You can't really
instantiate a class based on a stringname, can you?
Was I doing myself a disservice by using this technique in AS2 anyway?
Thanks,

[Flashcoders] ASDocDesktop - Easy documentation generation
Hello guys, I just developed a little application to easly generate the AS documentation of a project. You can find it herehttp://www.astorm.ch/blog/blogFiles/ASDocDesktop_bundle.zip(or on my blog http://www.astorm.ch/blog - FR). I'd like to have maybe some return about it ;) I tried to take out the files linked to asdoc from the FlexSDK and I have now a bundle of about 30Mo... maybe is there a way to do that more light :) Regards, Cedric ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
[Flashcoders] Lightweight Collision for Platform Game
What is the best collision system for a platform game? I've currently looked at box2D, but I think it runs amazingly slow on afew macs and other machines. Therefore I wonder if there is anything faster lightweight? I think I may need move towards a ray placed under the character instead of actually box-to-box collision. Any ideas?

The Flashplayer's native hitTest() is a fast bounding box test for two specific clips, or pixel-exact test for a point and a clip. But if you have several objects you need to test against each other, then minimizing the total number of tests should come first. A quad tree helps with that: http://en.wikipedia.org/wiki/Quadtree That should give you a small number of potential hits, which you can then test with a more exact (and expensive) operation.
