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?

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?
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)?
View 3 RepliesWhat 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.
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.
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") ???
View 1 RepliesSo, 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

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.
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."
I'm getting
ActionScript Code:
1067: Implicit coercion of a value of type
__AS3__.vec:Vector.ie.aro.floorplanviewer.model.buildingVOs:ConfigurationVO>[code]....
which surprises me as ConfigurationVO inherits from NodeVO.Is the compiler really not able to figure out that a Vector of a superclass should be able to hold a reference to a Vector of a subclass?
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?
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.
so i'm working mostly in a main class file. up until now subclasses (or the class for objects that i'm using in my game) have really only contained methods that controlled property values, and properties. however, i'm now interested in making an enemy in my game, but doing almost all the code for the enemy in the class file. i need to figure out how to communicate and check the object instance of the class against an object instance being controlled by the main class.

I've gotten stuck on a sound issue where I want the sound to play when the mouse passes over a symbol, which I've managed to get working, but unfortunately it is also playing when the page first opens, which I certainly do not want.
The script is:
cow.addEventListener(MouseEvent.MOUSE_OVER,gomoo); function gomoo(evt:MouseEvent) { var entermoo:Sound = new Cowmoo(); entermoo.play(); }
Given this: if(myVar){}, what will pass as true or false?In JavaScript for example, false are values like null, undefined, 0, '' (empty string), false.

I've written an event listener that passes 2 arguments with it. Now, after the condition is met,I've to remove the event listener but with no success..Here's the code:
//Function animateChar called on Enter Frame event with 2 arguments
www.addEventListener(Event.ENTER_FRAME, animateChar(184, 86), false, 0, true);
//Here's where animateChar is defined
private function animateChar(__x, __y):Function { return function(e:Event):void { var t = e.target; t.x += (__x - t.x)/speed; t.y += (__y - t.y)/speed; if ((Math.round(t.x) == __x) || (Math.round(t.y) == __y)){ t.removeEventListener(Event.ENTER_FRAME, animateChar); // Not working.. } } }
I have a project I'm working on and I am really stumped on making a seemingly simple animation work.The animation is of a coin scratching off a layer to reveal the layer beneath. I have the coin animated, and the layers in place. I am wanting to know if there is a way to erase/delete every place the coin passes over the stage, revealing the layer beneath. I've seen animations where ActionScript is used to allow a user to control the coin/pointer and activate the "scratch-off" effect. However, I am trying to come up with a method that is not a user-initiated animation since I want the effect to repeat in several places in the timeline.For the life of me I cannot figure out how to make this work. I am a moderately skilled Flash user and an ActionScript novice.

How do I write my class so it passes all of its functions/methods to the calling movieclip? For example, the following code imports my graphics class and creates a square:

var newSquare = vGX.createVector(this, 'square', 'rectangle', 20, 20, 0xff0000, 1, 0x0000ff, true);
That I'd like to be able to do is this:
ActionScript Code:
import sprites.vectorGraphics;
var newSquare = createVector(this, 'square', 'rectangle', 20, 20, 0xff0000, 1, 0x0000ff, true);

View 3 RepliesI 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.
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 {
[Code].....
How could I perform that super is StuffHolder test in a way that, well, works? In this case, it always returns true.
