ActionScript 2.0 :: Set Superclass Variables From Within A Subclass?

May 8, 2007

1: Is there a way to set superclass variables from within a subclass? I can't seem to accomplish it.

2: Also, why does it seem when I call a function, the superclass version is called instead of the sub? I construct the class using the sub, so whats the matter?

3: In one of the classes, I want to push a MovieClip it creates into an array, it works, but I get an undefined, then the value.

4: I have 3 levels of inheritance in my classes Specials -> Human -> Player, who do i call each one correctly from one another?

ActionScript 3.0 :: Superclass / Subclass Movieclip Linkage

Oct 6, 2010

I have a Hero class that extends a Unit class that extends a SelectableObject class.[code]I have a movieclip in the library that links to the Hero. Inside the movieclip is another movieclip with the instance name "selector".In the Hero I can use selector.gotoAndStop (n) because the movieclip is linked to that class, but I can't do that for the SelectableObject because it's not linked to that.Is there a way to make selector.gotoAndStop (n) work for the SelectableObject? I can't even do var something:* = this.selector because the movieclip isn't linked to it.Or should I just remove the instance name for the selector in the movieclip so I can declare var selector:* = this.getChildAt (1) in the SelectableObject (the selector being the second child)?

Actionscript 3 :: Call A Superclass Method From A Subclass?

Aug 15, 2010

What I would like to do is to call a method from a superclass in a subclass. Specifically I want to be able to add the subclass as a child of the superclass but without physically having to type addChild in the superclass (but I will have to type it in the subclass). For now I'm just trying to call a method in the superclass that draws some text from a subclass.

Here is the MAIN class (the superclass)

package
{
import flash.display.*;
import flash.events.*;

[Code].....

The code doesn't compile, I get "Call to a possibly undefined method DRAWTEXT through a reference with a static type class".

I realize there are otherways to display text on the screen. I just need to learn how to call superclass methods.

Actionscript 3 :: Change Subclass' Variable From Superclass?

Jan 3, 2011

For some time now I have been making a very easy game for iPhone in flash using as3. Recently I came in contact with a small problem, which is why I am posting this!

The problem: I have a superclass from which everything derives. In the superclass I initiate and place an Object on stage.

1. var myObject:typeA = new typeA();

2. stage.addChild(myObject);

As you can see this object follows the class 'typeA' which, ocf, has its own actionscript file. Inside of this file I have declared a global variable of type string.

What I want to do is change the varbiable on the new object from the superclass. Therefor I tried as following:

1. myObject.myVariable = 'someSortOfString';

Unfortunatly it didn't work and so I wonder how to do this; change a subclass' variable from the superclass.

ActionScript 3.0 :: Superclass Logging Its Subclass Methods?

Feb 25, 2011

I have an abstract superclass which has around 300 subclasses. I would like to log when certain methods on this parent are called, and I'd like to know the name of the subclass thats making the call. Is there any way to do this without rewriting all my subclasses to explicitly pass their names upwards to the parent's logging method? E.g., let's say I have a superclass Foo with a method writeLog(str). Foo has a subclass called FooBar, which calls super.writeLog("hello"). Can writelog just inherently figure out that a FooBar called it, without the need to rewrite everything so that we have to call super.writeLog("hello", "FooBar") ???

ActionScript 3.0 :: What Passes To A Subclass Extending From A Main Or Superclass

May 3, 2010

What passes to a subclass extending from a main or superclass, be it document or extending from a general MovieClip class etc? Does it pass absolutely everything from the superclass? That is to say, instance functions, variables defined inside these functions etc? Or just constructor variables? What passes through and does 'static' affect the transference of these values?

ActionScript 3.0 :: Superclass Default Values Being Chosen Over Subclass Changes?

Sep 3, 2011

I've run into an extremely odd problem. I'll give a code example to start. This is the superclass Building.

Code:
public var allowsEnemyMovement:Boolean = true;
public var information:String = "";
public var buildingName:String ="";

[Code]...

Now here's the odd part. Only SOME of the variables defined in the superclass do this. the variable information, buildingName and health all will take the default value from the super class. But the variable defenseValue will take its value from Factory's constructor. What am I doing wrong here? I would like to keep default values in the superclass so that I don't end up with null pointer errors later just in case.

ActionScript 3.0 :: Calling Subclass Method Through Variable Typed To Superclass

Nov 26, 2008

It's early days in my AS3 learning, and I'm looking for a little clarification regarding a variable typed to a superclass (in this case var mySpinner:MovieClip) which contains a reference to an new instance of a subclass (in this case Spinner.) I am trying to get my head around why my code compiles and runs and I am able to call the method rotater() on mySpinner even though mySpinner is typed as MovieClip, and the MovieClip class does not contain the method rotater().

On page 163 of the official Adobe Programming ActionScript 3.0 documentation it says the following, which I believe is related to my situation, but I am still in need of clarification:
"Because each class defines a data type, the use of inheritance creates a special relationship between a base class and a class that extends it. A subclass is guaranteed to possess all the properties of its base class, which means that an instance of a subclass can always be substituted for an instance of the base class."

ActionScript 3.0 :: Overcasted Superclass Method Not Triggering Subclass Method?

Feb 1, 2011

I have a class called Animal that has a method foo() and I call it out within the Animal class.

Code:
protected function foo():void
{
trace("Animal");
}

I also have a class called Cat that extends Animal and overrides the method foo()

Code:
override protected function foo():void
{
trace("Cat");
}

However when calling the function foo() from the superclass it traces out Animal not Cat (using a Cat object).How can I make superclass call out methods in the subclass?

Actionscript 3 :: Access A Superclass's Superclass In Flex?

Jan 17, 2011

I'm trying to override a subclass's method but I think I need access to the superclass one higher up in the hierarchy. So I'd like to do something like super.super.methodName();

FYI, the actual problem I'm trying to solve should be explained by my code below:

public class A extends UIComponent{
override protected function keyDownHandler(event:KeyboardEvent):void{
super.keyDownHandler(event);

[Code]....

If I use the class A's KeyDownHandler method, you will see that remove() is called regardless. However, the docs state that I need to call UIComponent.keyDownHandler whenever I subclass UIComponent. Of course this works for the first subclass, but not that subclass's subclasses.

I realise that I could put the functionality all into A with something like if(this is B){...} but that seems to me to be a hack.

How To Make SuperClass Available In Flex And Flash

Feb 4, 2011

I am working on a project that is utilizing Flash Professional and Flash Builder. The art team creates assets in Flash Pro and publishes the project as a SWC. I then copy the SWC into my Flash Builder project's lib directory and access the assets through that. The art team is creating a lot of the same type of thing; let's say they're making lots of lizard symbols/components. All of these lizards have similar animations (walk_left, walk_right, etc.) and because of this they all have constants defined in ActionScript (WALK_RIGHT_START, WALK_RIGHT_END, etc.) relating to the keyframes in their animations.

From the Flex side of things, whichever Lizard I load, I want to be able to tell it to walk left. So I created a superclass in Flash Professional and now all of the AS classes for the lizards in Flash Professional extend this class - Lizard.as This is all fine and good, but when I want to add more complexities to my lizards, I don't want to have to open up the Flash Pro project, edit the class, recompile the SWC, send it back to Flex, and then test it out. I want to be able to have my Lizard superclass available for editing in Flex - so I made another superclass in Flex: Lizard.mxml

In Flex, each lizard component (like Gecko.mxml) currently extends Lizard.mxml, and each contains an AS component defined in the SWC (Gecko.as in this case). This seems pretty convoluted: An mxml component extending an mxml superclass, containing an AS component which extends an AS superclass. What I'd like to do is define one superclass in the Flex project, have my Flash Pro defined components extend this class (which is the part I believe to impossible), and then have my Flex Components (Gecko.mxml) extend those.

Actionscript 3 :: Determine Whether Superclass Implements A Particular Interface?

Apr 8, 2010

Is there any non-hacky way to determine wether a class' superclass implements a particular interface?

For example, assume I've got:

class A extends EventDispatcher implements StuffHolder {
protected function get myStuff():Stuff { ... };
public function getStuff():Array {

How could I perform that super is StuffHolder test in a way that, well, works? In this case, it always returns true.

Actionscript 3 :: Change A Sublcass Variable From The Superclass?

Aug 18, 2010

This is basically the opposite of what I was trying to do earlier. I just need to know how to change a subclass variable from it's superclass. So if I were to make an object in a class how would I dynamically change a variable in that object from the original class that I made it in?

Suppose this is the main function of my main class:

public function MAIN()
{
new OBJECT_square().CREATE(this,100,100);
OBJECT_square.X = 40;
}

Changing the X value in this way is not working. I realize I can set/change the X value when I make a new subclass but I need to be able to change it as I go. I also realize I can change it from within the subclass but this isn't what I want.

ActionScript 3.0 :: Accessing Superclass Methods On An Externally-loaded SWF?

Jul 27, 2009

I'm trying to set up a large project that has a "shell" application that preloads and eventually displays a bunch of SWFs as a "slideshow". Each SWF could be authored by different people but will reference a base document class so they exhibit consistent behaviour. One of these behaviours is to be able to localise the slideshow into different languages. Since each SWF could have a different number of textfields that need to be localised embedded into their main timeline, the SWFs each must declare their stage instances in their document class. In order to implement the common functionality (such as a "localiseText()" method), I have decided to package all common functionality into a superclass (what I'm calling "Base Class" in this example) and using a subclass as each slide's document class.

This Example:This is a simple example I set up because in my actual project my compiler was throwing a coercion error when I tried to cast the Loader.content as my external class. The structure of this example is the following:

+ loader.fla : this is the main "shell" application.
+ SWFLoader.as : the Document Class for loader.fla
+ external_1.fla : this is the external SWF file that will get loaded and displayed

[code]....

I've set it up this way because a hypothetical external_2.fla might have different public variables to declare its stage instances so would need a separate implementation of ExternalBase (presumably External2.as).

The code (in reverse):

base/ExternalBase

[code]....

This just sets up the localiseText() method which is used in this example to change the contents of the text field. Since we don't know the name of the text field in the particular slide's timeline, we have to ask for it from the subclass' implementation of getLocalisableTextField(). We declare an abstract function here that needs to be overridden in the implementation.
