ActionScript 3.0 :: Access Stage Objects From Class
Feb 24, 2010
I'm trying to access a MovieClip created within the authoring tool from an ActionScript class. Here is my code:
PHP Code:
package {
import flash.display.*;
public class MoreVideos extends Sprite {
[Code].....
I also tried changing that to [stage.moreVideosBox.visible = false;], but I then got "1119: Access of possibly undefined property moreVideosBox through a reference with static type flash.display:Stage."
Is it possible to directly alter items in the authoring tool from a class? If I move 'moreVideosBox.visible = false;' outside of the class, in the main .as file, it works fine.

I made a document class for a project that is similar to this:
package{
public class test1{
// stage assets : these are all objects that were put on the stage in CS4
public var object1:MovieClip;
[Code].....
It seems the inherited class does not want to access the objects on the stage. Is this correct?

I'm having an issue accessing items on the stage from some imported code. I found this topic that discusses the same issue... [URL]
I'm not sure I totally understand how to go about this. I don't understand how to make the object global so I can access it from any class. (I have the same problem with an array I'm working with).

I have a MovieClip MainGame that is associated with my external AS File where all the code lies. Everything works really well but.. I place an object inside the MainGame movieclip and give it an instance name . Now when I try to access it from the .as it says "Access of undefined property xy.."
I tried it with textboxes and movieclips, all the same.. I know it worked 20 times exactly like this and I have even compared an older Game where I accessed it just like this.... I really don't know what Flash is playing on me..

I have a serie of boxes (Destination) and a box I can drag (Origin). I want that when I reach each of the boxes in the array(Destination) with the Origin box, the Origin box is "attracted" by the Destination box (each one) and that the Destination box change its status from 1 to 2.I tried it and it has worked to me with a single Destination box, but when I have created the array of boxes I can't access each of them. Below is the code I've written so far to clarify better where I am.
Code:
package
{
import flash.events.*;
import flash.display.*;[code].......

Im trying to get used to packages and classes in AS3. Im used to put all code on the first frame of the timeline, but now i have 442 lines of code on the first frame. Yeah 442. And this is for a game engine so i thought i should put it inside some classes to make it easier to read an reusable. But i have noticed that if i create a class called Code and make a instance of that class like this:[AS]var codeObject:Code = new Code();[/AS]i get a bunch of errors because the class cant Acess the stage and the display list.i found a workaround by linking the class to a movieClip and and do this:[AS]MovieClip(parent);[/AS?

How to access a display object on the stage in a class which is not a document class?
I am looking for a solution that doesn't involve passing the stage as a parameter to the class.
One solution i always come across is using "TopLevel.as". Is it a good method because as far as I have heard using global variables is not recommended because it might cause some problems while working on big projects.

I was wondering how do you access the stage property from a different class that's not the principal class tied to the fla? Essentially, I have main.as which calls another class menu.as, and I can't seem to be able to use the stage.stageWidth property from menu.as. What's the proper way to be able to use the stage property from any class? Do I have to import it separately each time?

I have created a class, that is simply a group of text fields. In the main app, I create instances of this class, and add them to the main app. How can i access the textFields that are in the class, to say, change the text, etc... When I try, I get this: 1119: Access of possibly undefined property txtHeadLine through a reference with static type Article.

I have a CustomSimpleButton class and a CustomSprite class which creates a bunch of CustomSimpleButtons and displays them at runtime. How can I access other objects on the stage in Flash inside of my two custom classes? If I want an object tween to occur when one of my custom buttons is clicked how do i reference the object that I want to tween if I'm inside of my custom class.

I'm building a Flex project with a lot of embedded bitmaps and such. The usual method for getting to the bitmaps in Actionscript seems to be to do something like
[Bindable] [Embed(source = '../lib/WhiteFencePost.png')]
private static var clsObstacleFencePost : Class;
var bitmap : BitmapAsset = new clsObstacleFencePost();
I've already got several dozen of these things, and I can easily see ending up with hundreds of them by the time the project's done. Is there some way that I can avoid creating a Class for every bitmap?

Let's say that I've a button object (instance of Flip) and a coin object (instance of Coin) on the stage. The coin object has two frames: one showing Heads and one for Tails.
MyCoin class is as following:
package
{
import flash.display.MovieClip;
public class Coin extends MovieClip
[Code]....
Problem: How do I reach the coin object on the screen via onMouseClick function? Let's say that the object on the stage has instance name of myCoin. I suppose that had I not done this with an external class and simply used actions from the frame I could just use the instance name as a variable. I couldn't figure to do the same it in an external class. Do I first create the object which is already on the stage?

Let say I have 3 objects of the MoveObject class. There is 1 symbol in the library linked to the MoveObject class. I dragged the symbol to the stage 3 times. Great.
If I type trace(this.x) in the class files it gives me the x value of all 3 objects.
My question is, how do I go through those x values one at a time?

I have a MC, instance name "jez_mc" this is inside an MC, instance name "container_mc". container_mc on on the stage.I then have an MC dynamically added to the stage. In this MCs timeline I want to access a variable stored in the class that is linked to jez_mc. This var that I want is named "score"So i figured in my timeline I could use something like:
var _jez_mc:MovieClip;
_jez_mc = MovieClip(root).container_mc.jez_mc;
trace("_jez_mc.score");

I'm trying to manipulate (in this particular case add eventListeners) objects (in this case some MovieClips) on the stage from a class that isn't the document class.
1120: Access of undefined property trans.
Now I know that it's probably a scope thing and I probably can't access stage objects directly from a non document class (as I'm doing in the code below) but I can't figure out how to access them properly.
Anyway, here's the deal:
I've got 3 dynamic text fields (called "NL", "FR" and "EN") on my stage in a movieclip called "trans". I'm trying to add eventlisteners in a second class to make them do something when clicked on.
Here's my document class:
package {
import flash.display.MovieClip;
// Import custom classes.
[Code].....

I am using CS3. And this is all about understanding Identifier and Class from the symbol property under Linkage.
I read some articles where all are using class instead of attachMovie() method on TimeLine.
Its confusing to me and couldn't able to make it work.
The article I read says that attachMovie() method will be in class file.

I'm trying to reference objects on the stage in the current frame from a document class in Actionscript 3 in Flash CS3. In this example, I'm trying to get at a dynamic text field with the instance name "question_txt", but there are also buttons and other things I'll need to get at to put event listeners on and such.
I have "Automatically Declare Stage Instances" checked in the publish settings, so the references should be there -- in fact, if I try to declare them in the class, I get errors about a conflict with the name -- but when I try to reference these objects (in any of several ways I've now tried!) I always get Null.
package {
import flash.display.MovieClip;
import flash.display.SimpleButton;
import flash.display.Stage;
import flash.text.TextField;
import flash.net.navigateToURL;

How in the WORLD is the rival class being repositioned on the stage? It does NOT inherret any other class, yet it still uses the "x" and "y" variables, and it looks like they are used the same way the regular ones are used.

This is for AIR: My document class imports a separate class "ConnMonitor" and uses it to constantly monitor the network connection. It's at the very end of that class where it's supposed to update a textfield on the stage as the connection changes, but the class can't access the textfield.
