ActionScript 3.0 :: Access Public Var/functions In The Document Class?
Mar 27, 2011How do I acsess public var/functions in the document class?
View 7 RepliesHow do I acsess public var/functions in the document class?
View 7 RepliesNo idea what I'm doing wrong here, it just won't let me access any of my public methods on my class. I just keep getting "Error 1180: call to a possibly undefined method"!
If I run the same function in the constructor of the class everything is fine.

I've created 2 public variables in my Document Class...
public var _wall1:Wall=new Wall();public var _wall2:Wall=new Wall();I've then added them to the stage and given them relevant instance names...
stage.addChild(_wall1);_wall1.x=32; _wall1.y=510;_wall1.name = "wall1";I then want to use these variables in another Class (Ball.as). They need to be accessed in a function within the Ball Class constructor.
function bubble(event:Event):void{if(this.hitTestObject(_wall1)){ this.x += 1;}else if(this.hitTestObject(_wall2)) { this.x -= 1;}However, the following Error message keeps appearing...
1120: Access of undefined property _wall1.1120: Access of undefined property _wall2.Any pointers? Do I need to import something into the Ball Class to point to the _wall# public variables in the Document Class?
I have the following inheritance structure:
var environment:AvEnvironment = new AvEnvironment(...);
addChild(environment);
environment.addChild(new Terrain());
environment.addChild(new Player());
I am trying to access a public property from AvEniroments class through the Player class, however I'm getting an undefined property error (#119). I've tried the following:
this.x = AvEnvironment.xs // public property in this class
this.x = parent.xs
I've also tried something like this:
var ev:AvEnvironment = AvEnvironment(parent);
this.x = ev.xs
but I get a TypeError. Error #1009: Cannot access a property or method of a null object reference.
I have searched for this everywhere but it seems like every answer is either overcomplicated or simply does not work, and I know for sure there should be a more simple way of achieving what I need. So, until today, I have always coded from within the timeline. But now I realise why I should code in separate class files. However, I still want to include snippets of code in the timeline for simplicity's sake.

i wonder why i am unable to access the public properties of this custom class the public var w:Number; and the Public var h:Number; i am tracing them and on an instance of the PreLoader() Class.. and ia m getting NAN;

View 5 RepliesI've been away from this forum for a couple of years but finally found the time to dig into AS3. Glad to be back (although motivated by frustration)
I have a main document (Main.fla), linked to a document class named "Main" in the AS-3-settings dialog box, but named "Main.as" on my harddrive.
I also wrote a simple tracing action and saved it as "xTrace.as"[code]...
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.
Going further on my app, I felt in another problem. Despite having lots of posts on the web regarding this, none of the solutions worked for me In my document class (Main.as) ve two containers. One empty and another with a star that is being imported from the library. Here´s the main class:
package
{
import flash.display.*;

I have 3 functions in my main document class that I want to execute when the main timeline reaches a particular frame number. how do I do that? see the code and comments

Got two classes "Engine.as" and "Player.as". Engine.as is the document class that is calling Player.as.
The point is to have Player.as create a movieclip on the stage, but it seems it cannot access the library or something. Because when the player class is at the createHero() method it gives me the "error 1009 cannot access a property or method of a null object reference"
Engine class:
Code:
package test{
import flash.display.*;
import flash.events.*;

It seems simple, but it doesn't seem to be working I have 2 as3 files as classes "mainclass.as3 (this is the document class)" and GamePlay.as3
the GamePlay class works flawlessly on it's own, but when i try to create the var to access it ... var gp:GamePlay=new GamePlay(); ... i get the following error.
I have looked at tutorial etc, but i cant get it to work i am currently getting the following error.[code]...
It used to be simple to access an object you put on the stage like a mc or dynamic text field by simply using _root.instanceName ect. Now I see references to making references to the Stage and such like:
private var stage:Stage;
stage = stageRef;
and I am still confused.
What I have going on is, I have placed a movieclip on the stage in Flash and gave it an instance name of Cell_mc.I have a cusom class that extends MovieClip with the following imports
import flash.display.MovieClip;
import flash.events.Event;
import flash.events.EventDispatcher;
[code]....
This Class is tied to a set of MovieClips in my Library.
I have a listener: this.addEventListener(MouseEvent.MOUSE_DOWN,pickUp);
And a function:
private function pickUp(event:MouseEvent):void
{
this.startDrag();
[code]....
I get the following error whenever I try to access an object I placed on the stage from anywhere other than the document class:
1120: Access of undefined property Cell_mc.
How do I access the cell_mc that is already on the stage from this non-document class?
if i want from a document class to access some variables in other classes (which are imported into that document class) does these variables need to be public to access them or they can be something else?
View 9 RepliesHow do I access the timeline from the document class? I tried: trace(this.parent as MovieClip)
but I got a null object.
I was wondering if it was possible to access the document class from within a movieclip.
I am creating a slideshow type project, and I'm using a document class to switch between the frames using the arrow keys. However, in one of the "slideshow screen" movieclips, I want to have it stop, and then play another part when the arrow key is pressed again.
I tried to access my nextScreenToPlay method within the document class, but whenever I try to do it within a movie clip, I get this error: Call to a possibly undefined method nextScreenToPlay through a reference with static type class.
If I do a trace(Main), within a movieclip, it shows the class.
trace(MovieClip(root).TRACE);
so at pesent I am using this to try and access
Code:
public var TRACE:String
in the the document class.
however I am getting this
"1180: Call to a possibly undefined method addFrameScript.�"
my document class extends to Sprite as I have some stage resizing that occurs on Initialise
Code:
StaticInheritance extends Sprite
Im sure it has something to do with the way the document class extends.
I tend to give my Document class all public access modifiers. Would there be any reasons not to do this?
View 3 RepliesJust tried using cs5 on my new macbook and I have a tlf text object on the stage with an instance name of mText. I tried to access (mText.text = "test") it like this and got a null object reference.

View 2 RepliesFor the example, there's a single FLA with a document class "main.as." In the public class main.as package, there is a public variable: "var example:String='example';." Inside of the FLA, there is one movie clip in the library and it is assigned a custom base class "sub.as." The movie clip is then placed on the first frame of the stage so its constructor is run at runtime and reads the value of example.
What is the proper way to get the value of "example" in the root document class? Using "root.example" in the sub.as class to target the document class returns an error and when I trace "root", I get "null." Main.example naturally throws an error because that's looking at the actual class and not the movie / stage its attached to.The round-about way I've done it before is to dynamically add the object in the library and pass in the root path when I create a new instance of it (example: submc:sub = new sub(this); ).Is there anyway to get back to the document class with a built-in method like root, etc?
I can access the targetObj instance inside the document class, but when I try to access it in another .as class,get this error:
Access of undefined property targetObj.
I m trying to access stage.width property but sometimes it trace 650 and 720 but i see my flash file dimension is 500x400, I need to align objects on stage..

I am trying to add a keyboard event listener to the stage, to detect when a user clicks the left or right arrow keys. But this listener is called from inside a class file which is imported into the document class, therefore I think it doesn't know what "stage" refers to. How do I solve this?
