ActionScript 2.0 :: MX OOP Inheritance And Callback's
Sep 29, 2003
i made an example so i can explein the prob better.[code]I am making a class and if have another build in object in it. I what to add a callback to it but the inheritance is not right. I know how the set up inheritance
1) subClass.prototype.__proto__ = superClass.prototype;
2) subClass.prototype. = new superClass;
but its all messed up in my head so I was hoping someone could point me in the right direction on how to get the callback to work with out messing up the LoadVars class too much

I have a parent MC (I'll call this mcFrame) on the stage that is essentially a square "picture" frame which I have applied a 'drop shadow' filter to. I have a child MC (I'll call this mcChild) which I have added to the displayList via AS3. This child MC contains a couple of paragraphs of static text.
So here is my problem: The 'drop shadow' filter I applied to the parent MC also appears on the static text (or any other type of content) in the child MC, how do I keep this from happening? To re-word my question? How do I stop the Child MC from inheriting the filters applied to its Parent MC.

I'm having trouble getting my inheritance variables worked out. In 'plain English', this is what I want:
base class enemy:
{variable HP;
if(HP<=0){remove instance}[code].....
But when I try to do this, it just gives me some error either about conflicting namespace or about the variable not being defined. I've done stuff like this before in GM and Python, but I don't understand how it's supposed to be done in AS3.

I have three classes (shown below, after the problem description).The first class (InteractiveStrategy) is the main class definition. In there I declare and instantiate two variables, download and upload, both of DataTxRx class.
On instantiation the folowing error pops up>> 1203: No default constructor found in base class strategy:DataTxRx public function Question(){ The second class, DataTxRx does two things only, either to download data or to upload data. As shown in its constructor, if the required parameter 'direction' is equal to DOWNLOAD, it calls the DownloadData() function. Similary, it calls the UploadData() if the required parameter is equal to UPLOAD.
The third class, Question extends the DataTxRx class, but itself has no constructor. However it has other methods(not shown) for adding, modifying and deleting questions anomg others.
package strategy{
import flash.display.Sprite; import flash.events.*;
import strategy.*;

I'd like to create some kind of component's properties inheritance to create generic behaviors in my component.Imagine I work a lot with textfield based components (counters, animated text... and so on), I'd like my artist to custom these components without being scared by the "update" button. Today, when component's code is updated, my artist has to update every flas using these components, and all of them are re-set to original look (if he had customed font color, or font size by duplicating the component instance, everything is set back to the current look of component).
That's why I'd like to know if there is a way for a component to inherit some of its properties and behaviors from another component class ?

And then I have a class called "Target" that extends AbstractTarget...how do I access the __movement property? Do I have to write the getter and setter in my Target class also and override both functions/methods?

If you have a method in your base class that is protected, can you override this method in your subclasses?

My data is of mixed types like String, Array Collection, Boolean. I have to populate the data into appropriate UI component - for example Boolean to check box, Array to List. So we have created a factory class which will return 3 different type of component based on the input argument.
CTextfield -> extends mx.controls.Text
CList -> extends mx.controls.List
CCheckBox -> extends custom.MultiLineCheckBox
MultiLineCheckBox which extends mx.controls.CheckBox and few methods are overridden to bring the multiple line label. [URL]. It works perfect.Am using the MultiLineCheckBox in the entire application wherever I want check Box. Now I went into a scenario where I want check Box instead of MultiLineCheckBox. How to rewrite my CCheckBox to handle MultiLineCheckBox and also default CheckBox? Each of the CCheckBox class has lot of methods init.

Without being able to modify the prototype chain, is it possible to fake multiple inheritance in AS3?
Say I have three Window classes. One is a DraggableWindow, one is a ScalingWindow, and one is a BorderWindow.
I want to mix and match new subclasses at runtime without having to make tons of new permutations of Window subclass possibilities.
Sure, I can implement these behaviors of the Window class as interfaces, but I would still have to account for all the permutations of interface combinations.

I am working on inheritance for the first time. Here is the super class
SetBlank.as
Code:
import flash.text.*;
class SetBlank {
public var _textFieldName:TextField;
public var _defaultName:String;
public function SetBlank(textFieldName:TextField, defaultName:String) {
[Code] .....
I can see the trace function working but the method which sets the text field to blank is now working.

My problem is I wish to find the x and y position of certain child objects. however when i try to display these values I am only shown their position when the child is initially added to the stage.Once the child moves due to the parent object moving, visually the child is moving, however when tracing or displaying the childs x position it remains static.Here is an abstracted version of my problem, it is all code based so it should run fine. The problem area is highlighted using comments and you will notice that the child positions in the trace logs do not change.

I am writing a simple application which communicates with web services a lot So I am listening for success and fault events very often. When service returns a fault, I show an alert to a user saying something like: "Sorry there was a problem with a service, we will try to call it later"
But there is a problem. When user didn't notice an alert, and service is still dead before the second call the alert will be shown again, and again and again (so There will be very many alert objects which is bad)
I want to make alert a kind of singleton. So I am trying to produce a class something like

I have an issue when consuming a web service from a Flex app. In the backend I have a hierarchy, let's say I have an abstract class Fruit, and 2 implementations: Apple and Orange. Fruit has a property, name, Apple has a property color, and Orange has a property radius. Then, I have a service wich returns a collection of Fruit. When I consume it from Flex, this collection returns objects wich type are Fruit, with its name property; but I lose all the properties for the implementation classes (color nor radius). So, the question is, does Flex support inheritance mapping when using web services? If not, is there any workarround?

i've been reading a variety of tutorials on the subject of inheritance, and i felt ready to try creating a chain of a few classes.right now i have two similar classes, Avatar and Enemy, which extend movieclip. What i'm trying to do is move a lot of their common functionality into a parent class which i'm calling Actor. I want to make Actor extend MovieClip, then make Enemy and Avatar extend Actor instead of Movieclip.[code]
What it says is true. I have an object in my library which is a movieclip. It's Exported for Actionscript with it's class as Soldier, and a base class of Avatar. this is the continuation of the chain. However it doesn't seem to want to work.As far as i understand, the above setup is pretty much equivilant to making a .as file for Soldier that extends Avatar.

example:
Code:
class Dot extends Sprite {
public function Dot():void {
ring.scaleX = 1.0;
[Code]...
If I attach the class Dot to the movie clip everything is fine, but if I attach the class Dottle to the movieclip the pre-export complains saying it can't find 'ring'. however, if I use this['ring'] everything works fine. I understand WHY this is, but I don't know what I should do to make it so it works w/out have to put this[''] around everything.

I'm creating an isometric game in AS3, Flash CS4.I created a file named Units.as which contains the following:
Code:
package
{
import flash.display.MovieClip;[code]....
The postoffice and cornershop movieclips have been set to the corresponding class names above.The file is in the same folder as the .fla and can be seen in the project window.When I compile, it doesn't include the Units.as file. Even if it just contains:
Code:
package
{
import flash.display.MovieClip;[code]....
if i create a class from the project window and select the movieclip in the library, it does include that file.So I'm assuming the compiler only includes .as files with filenames corresponding to class names.

I have a class called BgItem that I want many other classes to extend. But I also want to be able to use instances the BgItem class itself. Within the BgItem class file, I want to be able to detect whether the specific instance is of the BgItem class or an extension of it. I know I can detect if a class is in an object's chain of inheritance using the "is" operator, but how do I detect if a class is at the end of the chain?

In the flash IDE I have the file class com.example.NewCore. The NewCore class extends my original class named Core and the Core class extends MovieClip. What I don't understand is why isn't the original Core class able to access the assets on the stage? Or am I doing it wrong and should go about another way for inheritance. Heres alittle more back story... I had a project and it was fully developed. Now I have built another project based on that project with differently styled assets on the stage with same instance names. I needed to override a few functions but the class I extended can't access anything on the stage. I tried researching this but I can't identify exactly what I'm doing.My last guess would be to take everything off the stage and make it a class available in the library, but I don't know what the right way to do this.

I'm having trouble accessing the variables of my main class from other class objects UNLESS the objects are extensions of the Sprite or MovieClip class, have been added to the display list as a child of the main class instance, and I am able to use the this.parent.variable syntax. What I'm wondering is, isn't it possible to have a simple Object declared and instantiated, residing in memory and able to access another object's properties, without it being a part of the display list? Am I doing something stupid here?
Let me explain the code a bit in case it's a design flaw on my part. (I'm still learning AS3 and am not completely fluent with it yet).
I have a project with about 15 custom classes. There are no frame scripts in the .fla file. I am using it basically as a library only. The document class (let's call it Calculator for this example) extends the Sprite class and specifies the properties for the SWF dynamically. All other classes are instantiated from this main class. I have a bunch of variables that I want accessible to the different classes, so to keep them in a central location, I have declared them in the Calculator class, and am trying to access them from the other object instances.
(It should be noted that there ARE animations that need to play at times, so I'm assuming I can't NOT extend the MovieClip or Sprite class when creating the document class.
For this example, let's say there's another class called XMLLoader.as, whos instance was created from within the Calculator class, that needs some information stored in the Calculator class' variables. Incredibly simplified code for the two classes might look like this:
Document class:
Code:
package {
import flash.display.*;
public class Calculator extends Sprite {
[Code].....
So, in the code above (I've bolded the most important lines in red), the only way I have been successful at accessing the variables declared in the document class from other classes is to extend the MovieClip or Sprite class when I create the custom class, add the object as a child of the document class (Calculator), create a generic variable cast to the datatype of the document class, and use it to access the variables.
This seems really excessive to me, and I'm wondering if it is, or if this is simply a limitation of ActionScript. Does, for instance, a URLLoader object actually need to be associated with a MovieClip included in the display list in order to access internal variables of the main class object? Is it me, or is that really convoluted? Shouldn't it be able to exist in memory separate of the display list and still have access to varibles declared from the main timeline (i.e. the document class in this case)? Is there no other syntax for accessing these elements? Have I done something limiting with how I've designed this or declared the variables?

I have made a Flash app in which there is an class called "MyGame.Person" which has multiple subclasses "MyGame.PoliceMan", "MyGame.FireMan", "MyGame.Doctor" etc. "MyGame.Person" is defined in the main .fla file, but the other classes are each defined in separate .fla files. I have split each into its own .swf file so that I can extend the game without having to reissue the main .swf file.I then use a Loader to download each .swf file and call
var assetClass:Class = myLoader.contentLoaderInfo.applicationDomain.getDefinition(assetClass Name) as Class;
