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 :: 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 3.0 :: 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 :: TypeError: Error #1009 When Accessing A Method Or Property From A Subclass?

Jul 10, 2009

error When your accessing a method or property from a subclass. Here's what I have done so far but no luck in my script.

1. I tried waiting for my attached movieclip to be added to my stage using the setTimeout method but no luck.

var timedProcess:Number = setTimeout(initRevealDropDown, 1000);
private function initRevealDropDown():void
{
clearTimeout(timedProcess);
var myInterface:Interface = new Interface();
myInterface.revealDropDown();
}

2. I also tried extending my subclass to interface where my instance method is defined for revealing my dropdown menu, no luck on that one.

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 :: 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 :: Accessing Vars In SuperClass From SubClass?

So, how would you create a class that can access a variable in the class where the subClass was created(superclass), I realise this might be unclear so in example

PHP Code:
package {import flash.display.MovieClip;public class Main extends MovieClip {public va demoString:Strin = "TEST";public static var newClass:SubClass;public function

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.

Flex :: Sequence Flex/Actionscript Method/function Method Calls

Aug 11, 2011

OK, from what I know actionscript in Flex runs asynchronously. I need the ability to run a method in a loop synchronously. Consider this code:

public class CustomerContainer extends VBox
{
public function CustomerContainer ()
{

[Code]....

This is not my exact situation as it is a bit more complicated to explain here. There is an abstract class and several custom view objects derived from it. Some of the views are dependent on others being completed first but I cannot seem to order them in the correct order. TIMERS are not an option. Probably not explaining this correctly.

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.

What is the best way?  I discovered how to do it by loading a movieclip with the image, but that is risky because depending on the connection, it sometimes loads too late.
