I am new to AS3 and am working on a project where I got stuck trying to figure out the best way to access a variable set in my MainDoc from a subclass. Nothing I've read has either made sense or seems like best practices. I understand a little about encapsulation to know that a subclass shouldn't be able to listen to a parent, but there has to be a way to do this with OOP in mind.[code]...

I'm trying to access a button through my subClass, the button I'm trying to access is located on timeline and this is the error I'm getting once I run the code:1120: Access of undefined property btn_Test., maybe someone could look at the following code and indicate what cause the error

I am trying to figure out how to get access to a display object that was created in one subclass from a different subclass. Here�s my example: I created PnkRabbit.as and BluRabbit.as as separate classes (both extending RabbitTemplate.as).
I called them from Client.as (document class for Rabbits.fla) using an addRabbits button. Then I created MovePinkRabbit.as and MoveBlueRabbit.as (both extending Move.as which is listed as a protected var in RabbitTemplate.as). With this setup I can run Rabbits.fla and get a trace statement to come from MovePinkRabbit.as and/or MoveBlueRabbit.as, but I can�t figure out how to get access to the PinkRabbit and BlueRabbit movie clips from MovePinkRabbit.as and MoveBlueRabbit.as, so that I can actually move the clips. Here�s some of the code, (complete code and FLA in zip file).
Client.as
Code:
package
{
[code]....
I've defined two classes, one of which extends the other. The superclass defines a constant and I can't seem to access it through the subclass.
Code:
public class BigClass
{
public static const BIG_CLASS_CONSTANT:String = "Hi Mom.";
[Code]....
Shouldn't polymorphism allow a subclass to access constants of the classes they extend? Does the subclass have to reference the parent constant in some other way than a simple extension? Do I actually have to declare that constant in each and every class that decided to extend from that parent (but then how would the parent refer to it?)? Or (and this is the most likely) is there something completely different that I'm missing?
I am calling on different types classes from within a loop. The objects can be of different types so therefore I am using the getDefinitionByName method. here is a piece of my code:
for(var y = 0; y < mapH; y++)
{
brickHolder[y] = new Array();
[Code]....
But I got an error when I tried to call on methods. The interface is blank; doesn't have any methods in it. I am not sure if that makes a difference. But the parent class inherits it and the subclasses inherit the parent class. Can I instead use the parent class?
var brick:ParentBrick2 = ParentBrick2(new classRef());
In a nutshell, what can I do to loosely cast these objects so I am able to use any subclass methods that get called?
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.
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."
Can I access a static variable of a subClass' subClass? I don't want to instantiate it, just looking to get the variable because it has already been initialized by the subClass.example:
package
{
public class A extends MovieClip {
private var classB:B = new B();
[code]....
It's too complicate to explain but I'll give you an example
I have an AS3 ResultEvent Object and this object has several propeties which can be accessed by this like:event.result.name or event.result.age and, I have this String variable: eventProperty:String that contains "name" or "age" How do I access to event.result. with the variable?
How can I access the member variable of an object by using a variable in the name.Example:
Entries Object has properties 1, 2, 3, 4, 5.
Normally I would access them by
var i : int = Entries.1;

i'd like to access a variable in an associated class from my Document class [code]in my document class im trying to see if the class has changed the variable... if it has changed i'd like to obviously do something.if this isn't possible what's the simplest way to check a variable in another class?

How to access a local variable from another class? I have this powerup class that changes the speed value of the enemy in enemy class(it's a game). For instance, if player hits the powerup it changes the local variable 'speed's value inside enemy class.
View 3 RepliesOn the first frame I have a string variable called "nextSection". When the user clicks on a menu item on the site then "nextSection" is populated with the name of that section. Later on in the fla I have a movieclip containing various sections for the site. The swf compiles without any problems.
I'm now attempting to make the file smaller and easier to update. Rather than have 8 different movieclips that load images, I thought I would just have the one. I changed the following lines in my fla
PHP Code:
// nested within 2 movie clips (sections.aboutUs)loadImage("aboutUs/mainImage.jpg");//nested within 2 movie clips (sections.outdoorAdvertising)loadImage("outdoorAdvertising/mainImage.jpg");// there are 8 of these in total.
[code]...
I'm now getting the error "1120: access of undefined property nextSection". The variable does not contain anything when the file compiles. Only when the user clicks on a menu item does the variable get filled (ie: if user clicks on the OutDoor Advertising button, the variable contains the string "outdoorAdvertising" which is also a folder in the site directory). I tried to populate it with the name of one of the sections on the first frame ( ie: nextSection:String="aboutUs"; ) just to see if it worked but still got the error.
i have variable a=0 and i want a movieclip that runs to change it to 2, what do i write in the movieclip code ? i tried parent.a=2 but it's error.
View 4 RepliesI have a MovieClip who's added on stage by code.I would like to access to rond2(which are an instance of rond on frame 10) but one error appeared like you can see.This the code that i've maked on first frame on the scene:
var monCarre:MovieClip = new mv_carres();monCarre.addEventListener(Event.ADDED_TO_STAGE, leDire);
addChild(monCarre);monCarre.x=275;monCarre.y=200;//monCarre.rond2.alpha=0; <<<<L'éxécution de cette ligne provoque une erreur
function leDire(e:Event):void{ trace("monCarre est ajouté");}
Normally, I declare a variable at the very top of all my code like, var myObj: Myobj = new Myobj();...
but for some reason the the new variable being declared is necessary to present within the function, like displaying same objects in the library using for loop.
I notice that variable declare within a function will not be accessible outside the function or from another event handler or from another function....
I have seen code that make it possible my declaring a new variable?
I have a class with a var textFieldObjets:Textfield in my class environment. What I'd like to do, is access this var from another class and change the text. I tried things like

View 1 RepliesI have 2 classes: A Main.as and XmlLoader.as. In Main.as I now want to access a variable of a XmlLoader-instance, which has been changed in run-time by a Event.COMPLETE EventListener.To make things clearer here some code:
Code:
Main.as:
package {
import flash.display.*;
[code]....
in Main.as I want to trace (trace(_xmlData._xml)) the xml file which is loaded.
function fn1(var2)
{
//here i want to trace the name of var1....ie output: "var1"
}
fn1(var1);
how to trace the variable name i am passing to fn1 (ie. var1) as string?
ie. output shoud be
"var1"
ie i want to trace the name of argument variable i am passing
[code]...
I keep on getting the output "undefined" everytime trace was called.
function loadHandler only runs one time .. since it runs only once it makes it very difficult for me to do anything with.I can only access the variable "myClip" inside of the function.... if I could access it outside of the function I would be able to write some if statements.Basically what I am trying to do ... is the first time this script runs ... I don't want "myClip.gotoAndPlay(2);" to run. Every other time this frame of code runs .. it wont run the function a second time. So I need to somehow tell it every time it runs after the first time to run the code myClip.gotoAndPlay(2);

I am trying to access a text object inside an MC inside a variable (with a corresponding Symbol name) after dynamically attaching an MC. the code that sets the "dockTemplate" variable is below. I'm trying to write to the "item" property called "label" on a rollover function called "dockRolls".
var dockTemplate = {
layout: 0
icon_size: 80,
icon_min: 50,

externally, there is another AS file that extends the MovieClip class which is setting up the functions, etc. in 'var dockTemplate'. that seems to be working fine. my question is:
HOW do I write to/access the text object 'orderEntry_txt' inside 'dockTemplate'?
