I have a class which extends the Proxy class, and has a statically defined member variable called num:
public dynamic class TestProxy extends Proxy
{
private var num:Number = 100;
[Code]....
I want getProperty() to be called when I attempt access num. It works for any field which does not already exist, but not for fields that are predefined.
I have an actionscript project which uses visual symbols from an SWC. I have a CheckoutButton which has the following class associated with it (compiled into the SWC in Flash CS3).

is there a way to override a MovieClip's parent and stage properties? In a custom class extending the MovieClip class we can override the get parent() and get stage() methods. But is there a way to do it to existing MovieClip?
I mean I have an external swf content (loaded) and assigned to a movieClip. But now, how can I assign the loaded MovieClip to my custom class, so that it "doesn't see" the parent and stage properties?
Or can I override functions of existing classes? Sth like:
override public function myMovieClip["get parent"]():DisplayObjectContainer
{
...
}
I just need to prevent a loaded MovieClip from having access to the main movie's stage.
Is my understanding that there are no Abstract classes and you can't override or overload constructors of derived classes correct? Abstract classes aren't important for me but if it's possible I'd like to know how. But is there a way to overload default constructors and I'm just doing something wrong? Can we only override methods or can we overload them also.For a simple game I'm making, I'm not using FlexBuilder and don't want to for this project for specific reasons, so I'm using Flash and instead of using sprites and bitmaps I want to draw shapes in Flash and covert them into MovieClip symbols which I "link" for export as AS to use in my code. I want to make it a little modular so I can just change certain aspects of the code for different approaches.If I create a class Actor which extends MovieClip the default constructor has to be Actor() with no arguments. But I'd like my class to be able to have arguments like initial x and y coordinates. I know you can just create methods to initialize each part but I'd like to try and have a default constructor to do so.
In Flash I notice that if you derive a written class or built in class it requires the standard default constructor, "which I may be wrong about and I hope I am and someone could show me what I'm doing wrong", I found if you derive a class based on a symbol you linked for export as AS I can create a new constructor with whatever argument(s) I want (so this is why I'm making this post,if I can do this couldn't there be a way to override
constructors?).
1) So I create a base class called Actor which extends MovieClip save it as Actor.as and default constructor of Actor() add whatever properties I want.
2) Then I create an object in my library, let's call it mcShip, then I link that symbol for export as ActionScript and have it's base class as Actor and name the class ShipMC.
3) I then create a new .as file and call this one ShipActor.as, this class ShipActor extends ShipMC and then I create a default constructor ShipActor(gs:GameScreen, xA:Number,
yA:Number) and this works fine (also I create a method in Actor class called ActorSuper and call it from ShipActor with passed in arguments, since I don't know of a way to overload the parent class' constructor)
If I were to just have my mcShip with a base class of flash.display.MovieClip and I try to create ShipActor with the constructor above it says missing default constructor. The above 3 steps is the only way I can get it to work for now. Is there a way to overload the constructor? If not are there any other work arounds?
Is there any way to override static functions of Flash top level classes? Lets take Stage or Math for example. What if we want to change Stage.addListener functionality, is there any solution to this problem?

Note: This is an Actionscript project, not a Flex project.
I have class A defined in an RSL (technically, it's an art asset that I made in the Flash IDE and exported for actionscript. The entire .FLA was then exported as a SWC/SWF).
I my main project I have class B, which inherits from class A. The project compiles fine, with no errors.
However, when when the project runs and I try to create an instance of Class B, I get a verify error. Creating an instance of Class A works just fine, however:
import com.foo.graphics.A; // defined in art.swf / art.swc
import com.foo.graphics.B; // defined locally, inherits from A
...
<load art.SWF at runtime>

I just started using flashdevelop and I have some problems with importing all classes.
1. I used export all classes to SWC file and I added it to the library in FD. How can I import instances placed on the stage without creating AS linkages? I don't want to export these instances for AS, because some of them are textfields. By making linkages I'm forced to transform them to Sprite or MovieClip (am I right?) and my methods connected to these object don't work anymore.
2. When I export my project in FD, I get error 1065: variable Main is not defined. Main is my document class. I made this class my entry in FD.
I'm new to AS3. Learning how to create classes. Is comp = new HouseObjects creating a new class? Is comp creating an instance of the HouseObjects? I realize that this is inside public class TreeHouse. I'm thinking that HouseObjects, how I set it up is not a class...not sure what the correct way to set up classes and properties.
Also I noticed, that when I tried to link another movieclip using the same linkage name HouseObjects--it asked to enter a unique class. I'm trying to create multiple instances from the same class called HouseObjects.

View 2 RepliesIm building a project using an MVC pattern. I have (pseudo) abstract classes Model and View, each extended with particular models and views. But I cannot access properties on the extended classes of Model...Model simply distributes XML data, heres its constructor:
Code:
public function Model(data:XML)
{
_data = data; /*_data is a protected var of type XML in Model*/
}
MainModel extends Model, and has a property called _background of type Background which also extends Model:
Code:
private var _background:Background = new Background(some XML source);
public function MainModel(data:XML)
{
[code]....
The problem arises when I try to pass MainModel's background property as a parameter of _bgView (highlighted in red above). The compiler says there is no background property on Model, which is true, but I need it to look at its extended class MainModel, not Model. I've typed MainView's constructor parameter with MainModel, but it is still seeing it as Model.

I have a question about classes. I just learn that static means that functions and/or properties are specifics to a class, but is it a synonym of private? And why statics (not available to any instances?) properties and/or methods can have a public (available anywhere else (timeline)) access modifier? PS: I just start with classes.

View 3 RepliesI am using flex builder 3.2, Action Script 3 and develop for Flash Player 10 and am quite new to it. when I call a method of a self defined class, I get the 1061 error (not defined). But the class and the method exist and are public, so what the hell am I doing wrong? Flash Builder is even offering me this method in the auto-completion, so at least the builder knows it... I have already tried cleaning the project (as this is the common source of strange errors when working with java/eclipse),
edit: solved... The problem was that a package had the same name as the variable I used for the class. Very strange error message, thumbs down for this .
Just been playing around with the tutorials, on the Set properties/Get properties. Everything is all cool, except the "instance name" aspect. I dnt really understand that too well. Is it possible to change an Mc Name dynamically? If you look at my FLA when you hit the top left red button you will get a trace of the mcName as "square". Now if you input a new mc Name on the right hand side, you will see it change on the left hand side. But i want to know why it doesnt remain as the new mc Name, it still goes back to square.
View 3 RepliesI forgot to put it in the title so I'll just place it here; I am using AS 2.0. I know that there are other ways to accomplish the goal that am after, but I was wondering if anyone knows of a way to access the properties of an object's properties?
Here is the code that I thought of, even though it doesn't work
var a:Object = new Object();
a.bproperty = 0; //lowerlevel properties
a.cproperty = 1; // lowerlevel properties
[Code].....
This really just boils down to how I am organizing the code(I have ideas on what do next, and i am 99% sure that I can get them to work), and if there is a way to dynamically access the properties of the objects properties, It will save me from creating yet another large block of code for my project.

Is there any way to auto-import as3 classes (internal/intrinsic Flash Player classes at least) using Emacs ?
Looked for as3-mode and actionscript-mode but nothing working was found. as3-mode can import class if it is opened in buffer (but not *.mxml files)
The examples I'll use don't do anything - they're classes without ANY members - no variables, methods, anything.
Let's say I extends Sprite and call it MySprite.
I save it in test.core
[code]...
Now I create another custom class called MyWindow that extends MySprite.
I save it in test.windows
[code]...
Then I create another class that extends MyWindows (the example I'll use is a document class - but that doesn't matter - I've tested using an instance too).
[code]...
Notice that I'm not even trying to instantiate the helper classes - just having them there throws the error.
If there is only a single helper class, everything runs fine.
Also note that - as far as I can tell - this only happens when extending one class from another package, then extending that class with more than one helper object.I'm pretty sure there's no namespace bumps or typographical errors, as this is a very pared-down version of the original application.
EDIT: seems the problem exists even without the crossing packages - even extending MySprite in the document class with multiple internal classes generates this error.
I am creating a library in AS3. Inside the library I make use of a bunch of classes/packages that need not be exposed to the end user of my lib. I want to only expose one of these classes.
I guess my questions are:
1) How are libraries commonly distributed in AS3?
2) Is there a .jar equivalent in AS3 that developers can include, but will only have access/knowledge of the classes I've declared as public?
I'm trying to import a class from a class that is located in another folder. How do you move up a directory? Using./ or ../ doesn't seem to work. Essentially I want to access a TweenLite Class but not from the document class. My class is at com/myName and the class I want to access is at com/TweenLite. import ../TweenLite doesn't work... I realize I could just copy and paste the entire Tweenlite folder again, but there's got to be a less duplicative way of doing this..
View 2 Repliesinheritance and building classes from other classes.
I have 3 classes:
gfxRoomText - changeable colour
gfxRomInter - changeable colour - interactive
gfxRoomImg - interactive - only image / no colour
The first two incorporate the same text field and functions to change colour. The second and third incorporate another class to interactive with. What is the best way of creating these classes using inheritance and how?
