Actionscript 3 :: Access Variables In Main Application Class From Instantiated Class?
Apr 8, 2010
I have a initApp.as which instantiates a class which needs to access the "currentState" property and the States array as well. However we cannot get this to work as we cannot see how we can access this information.
Within initApp.as currentState is accessed via "this.currentState". This does not work in the class which is instatiated within initApp.as. The following error is thrown:
"Access of undefined property currentState."

I have question regarding removing instantiated objects. Let's say i have a main class in which i instantiate a custom video player (or whatever) class:
Code:
...
var videoPlayer = new VideoPlayer(...);
addChild(videoPlayer);
...
And inside VideoPlayer class i have of course dozens of objects (movie clips, sprites representing different parts of VideoPlayer) and dozens of event listeners attached to them. My question is, if i want to remove this VideoPlayer class from my main class is it enough to just do:

I have a MC with a class attached to it, and I have other MCs within that MC. I need those MCs to be able to access variables within the main MC class. Here is a quick'n'dirty:
Code:
class Foo extends MovieClip{private var h:Number;
private var subMC:MovieClip;function Foo(_h:Number){h = _h;}
subMC.onEnterFrame = function(){trace(h);}}
How can I access variables in the Foo class from another MCs scope? I have tried using static var but aren't they constant regardless of instance?

My first experience is build an aquarium with a lot of fish swimming, and they can be clicked. When one of them is clicked we should receive a trace message saying ("I�m a Fish!"). To do this, I thought that the best way will be:
1- create a document class, named Main.as
2- create a base class, named Clicked.as
2- create a movie clip with a fish.
3- export the movieclip to actionscript. In the mc properties set Class as "fish" and Base Class as "Clicked".

i have a game that i want to put load screen on, which i created a separate class for. first the main class is initialized and in the constructor function, it does an addChild(loadScreen) which places an instance of the loadScreen MC on the stage. within the loadScreen is a "Play Button" that when a user presses this button i want it to continue startGame in the Main class. the way i tried it was Main.startGame from the loadScreen class, but that obviously does not work. is it possible to call a function from a different class.i have three files:
Main.fla
Main.as
loadScreen.as
the Main.as file:
Code:
package
{
import flash.text.*;
import flash.display.*;

I'm wondering if anyone has experience with if there is a big difference in performance in ActionScript 3 between keeping a class with only public static functions, and utilizing those functions often (as in a frame event at 30fps), and in turning the class into a "normal" class of which I instead make an instance and call the functions via the instance instead.

I am making my way with AS3 in little steps and have hit a road block. This is what I have:
I have a document class called "Document Class" I have a custom class called "Game"
I have instantiated an object of "Game" class and I am able to trace a class method which return a simple "HELLO". within my Game class, I have a variable(type Array) called "questions" as instance variable.
I would like to add questions to "questions" array by using "Mutator" method, or count the current elements with the questions array and return the total number of questions. I am unable to add or access elements to the questions array.

I have a class called shapeC that only creates a rectangle and then addChild(rectangle);. That class is instantiated on the main timeline. Currently, the only way you can see that rectangle is to add the instantiated class to the stage via addChild(shapeC);. My question is, is there a way that the shapeC class can add the rectangle to the root stage without requireing the instantiated class to be added to the stage?

I'm trying to mediate the main application class ( the 'Document class' of a Flash *.fla project)I have this on the Application Context startup():
...
mediatorMap.mapView(MyApplication,MyApplicationMediator);
mediatorMap.createMediator(contextView);
The MyApplicationMediator:
public class MyApplicationMediator
extends Mediator {
[Inject][code]....
So onRegister() gets called, but view is null. Also when I try to add the eventListeners I get a null reference error.

I'm writing an Air application using only Actionscript, and Flex3 SDK as the compiler. Everything compiles and runs fine under adl, but when the final air file is built and installed, the main class is never initialized.[code]When run under ADL, "Init" will be output to the console, but when installed and run, nothing happens (the constructor for class main is never called).

Im a complete beginner in Flex programming. I have an application with a main .mxml file, and a certain class Foo that I call from the .mxml. In Foo, I make a URLRequest and listen for the Complete event. Then I found myself with the returned data in a Foo function, but I have no idea how to communicate it to the .mxml part of the application ! I looked into ArrayCollections but I can't seem to understand how they work. Isn't there a way to modify, from inside the class, a variable with a global scope ?

I am just writing this test code in AS1.0. Now the problem, I am not able to get access to my class variables. I am doing this stuff for learning As1.0. Although in 2.0 I get through those using static variable. But in As1.0 I don't know how to do this.
Code:
function main(){
this._xml=new XML();
this._arImages=[];
this._xml.ignoreWhite=true;
this._xml.onLoad=this.LoadData;
} main.prototype.showImage=function() {

I have a class, and I'm trying access an object outside of that class. For example, in my class I have function: onNodeLoad(node:Object)with that function I can access the properties of node just fine, but outside the class I cannot.In the function that is inside the class, I can trace (node. title)I want to be able to do that trace on the main timeline.[code]So right now, in my main timeline, trace(con.node) comes up null.I've tried to declaring _node public, private, public static.

I usually use if(object!=null) but it doesn't work well.
How can I verify if the class is instantiated. I want to get rid of the 'cannot access a property of a null object or reference'.
I mean, the 'var object:Object;' is just a reference to an Object class instance. When i initialize it with 'object = new Object()' it runs the code in the constructor, initializing it. How can I check if it has been initialized or not.

I've been struggling with this for almost a day now and I can't seem to find the problem. I'm making an instantiated FLV playback class in actionscript 2, but it just doesn't play the video
Here's the code, if I uncomment the camera parts and attach _cam instead of _stream it will show the camera feed, it just won't play my movie (and I get no errors whatsoever).

I'd like to access the stage of the main timeline from w/i a class that extends a movieclip. Basically, I have a button in the main timeline that makes a HUD appear. The HUD is an extended MovieClip class. When people click on a button in the HUD, I'd like to remove the object from the stage of the main MovieClip.I think your confusion may come from the fact that I am running this code from a class definition file. Clicking on a button w/i this object should remove it from the DisplayList of the MainTimeline. Here's the code from the class definition file:
package classes {
import flash.display.Stage;
import flash.display.MovieClip;[code]....
trace(e.currentTarget.parent.parent) gets me the MainTimeline, and trace(e.currentTarget.parent.parent.stage) appears to return the main stage, but I cannot use removeChild w/o getting an error that I am trying to coerce the stage to be a DisplayObject (which it ought to be).What's on the stage of the MainTimeline: A single button that, when clicked, adds an instance of the Answers class to the stage.

I have 3 dynamic textfields that are added to the stage through an external class, (I only add the main container from the Main.as) the textfields are nested under 5 MCs (that's what i see when i list objects in the debugger) how can i access those textfield from the Main document class?I've tried by path, by getchildbyname, i've exported the font for AS (the textfields have instance names)... and nothing works, i either get an error or it tells me it has no properties, or null..

Anyways, I've been trying to figure this out for quite some time.Let's say I have my document class. I'm guessing the document class can correspond to the first thing that gets run? (such as the "main" function in most C++/low level languages).If I set a variable in it:var myNumber:Number = 10;how would Iaccess: "myNumber" from other objects in my stage?Like a movieclip on my stage for example.If I go inside that movieclip into the movieclip's first frame, how would I say:trace(TheDocumentClass.myNumber);Another similar question is, what about the actual stage frame?If I click on frame 1 of my stage, set a variable:var aNumber:Number = 5;how would I access it from other objects?In my movieclip's first frame, what would I put?trace(root.aNumber); ?trace(stage.aNumber); ?

This is the class file:

public function setModule() {

When I access the getModule method from flash (on click of a button), I get modArray as undefined.
how I could get the data of modArray?
