Some constructor methods I've seen have the return type :void, even though they can't actually return any values anyway. If it's not required, is there a standard/best practice for that?

I'm extending the AS3 class Rectangle with a class called Bin. I want to override the Rectangle clone() method with a method that returns a Bin object, not a Rectangle object. If I try to override the clone method but specify Bin as the return type, I get a #1023: Incompatible override error. Here's my Bin class:
package {
import flash.geom.Rectangle;
public class Bin extends Rectangle {
[Code].....
This class works, but when I use the clone() method to create a new Bin instance, I get type errors when I try to use the Bin methods on the new instance.
How do I override clone() and send an actual Bin instance?

I have a class. I can call the constructor (initialize the class), and the constructor can then call a function/method inside it's own class (so I know it works), but when I try to call the same function/method myself from the instance of the class I just initialized, I get an error.

I'm making a kind of image showcase, what has a fluid width and height, depending on browser window dimensions. Everything is okay, I have other kind of issue: in constructor function in this gallery class I can't use stage property, I have to get it from main class. Why Flash treats me this way and how I can avoid this currentStage variable?

import flash.display.Sprite;

View 1 RepliesIt doesn't appear to be possible to get the return type of a function. Is this correct?
View 1 Repliesi want to essentially classify a simple function in it's own .as file. the function compares integers. but i don't know how to call the class and receive a boolean return.
here's my class
package

public class CompareInts

so now i'd like to write something like this:
if (CompareInts(1, 5) == true). or output 'true' by writing trace(CompareInts(1, 5));

The call gets made and I get the alert of either "Returning TRUE" or "Returning FALSE" but the result in the boolean "visibleRet" is always "false" in my "throw" message. Is there something special I need to do in order to grab the return type correctly from the javascript call?

However, I expect that currentFig would contain a reference to a Figure object created in AddFig method, but it's not. What am I doing wrong? Why does an object exist only within a method?
is there a method to return the datatype of a variable?
View 3 RepliesI'm getting into actionscript3 and was wondering if there was a way to make an 'onclick' type function that returns an id or an instance name. For example in jQuery you can do the following, which is great for then passing the id into an array or whatever you choose.
$('.menuButton').click(function(){
var collectedID = $(this).attr('id');
Is there an equivalent to this in AS3? I'm assuming grabbing the instance name would be the goal? I haven't run across ids in Flash yet.

Using the web services panel, I've connected to a web service, but all the method calls will only show the param structures/types - not the result structures/types. To the best of my knowledge, I'm sending the right parameters, in the right structure, but always I get an empty response.The web services panel:

So there I was, creating a small app that allowed user to upload custom images. Everything went smooth, until......<insert horror music here> So you want to validate that its an image, and not something else. Well you restrict it with the File filter...but there are ways around that. So as a double check, you check the file type after a file is selected. <drum roll>
Awesome, the type method returns null if the image doesnt have the proper headers....what the hell....So most images are compressed for smaller file size, thus the headers are stripped out. So...Type method appears to be useless....There was a simple way around this using the name method..but what the hell...type method is weak!!
I have been away from actionscript for a long time and not 100% why this is happening, I will simplify the class below[code]...
call to a possibly undefined method through a refernce with a static type?
I need to know the best method to find an item inside a list (Vector, Array, Dictionary, whatever is faster) of complex type (extensions of Objects and Sprites). I've used "Needle in Haystack" method, but it seems that it isn't fast enough.
E.g. Suppose that I have a collection of Sprites (a pool, in fact). Each sprite will be added to the stage and perform some action. After that, it will die. I don't want to pay the cost to dispose it (garbage collect) and create another (new) one every time so I'll keep the dead sprites in a collection.
Sometimes times I'll call a method that will add a sprite to the stage. This sprite can be a old one, if it is already dead, or a new one, if the pool don't have any free sprite.
One of the scenarios that pushed me to this question was a Particle System. A "head" particle leaving a "trail" of particles every frame and exploding into a flashy multitude of particles... Every frame...
Some times this counts up to 50.000 PNGs with motion, rotation, alpha, event dispatching, scale, etc... But, this is JUST ONE scenario...
At the moment I'm trying to use a Object Pool with a Linked List... Hopes that it will be faster that running a whole Array/Vector or create new instances every frame an let them dye with Garbage Collection.
Error: Access of undefined method getStatus through reference with a static type Class.
Here's what's happening in the code. I'm trying to create a User class that is instantiated at the start of my app. I want the User class to have properties like mainStatus, with helper methods like setStatus etc. Pretty simple.
so on my HardDisk I have my flash_working folder with all my flash projects. I created my class file/package under the directory com.mypackage
[Code]....
That's all the code I have.
If I try to access the public var mainStatus through user.mainStatus that gives a similar error saying:
Error: Access of undefined property mainStatus through reference with a static type Class.
