View 5 RepliesHow 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 cannot get my buttons to work. Here is my new document class. http:[url].....And here are the errors I got for each mention of b1_mc, which is just a movie clip on the stage.
1120: Access of undefined property b1_mc
Since I have import flash.display.MovieClip; at the top of my class, why do I keep getting this error?
I have a MovieClip in my library called WindowHider. The timeline for WindowHider contains a frame-by-frame animation that is made up of individual PNG images that I imported. Each of the 10 or so PNG images sits on it's own frame within WindowHider.I can successfully create an instance of WindowHider within my Document class and add it to the display list.
Question: Is it possible to access the smoothing property of the PNG images within WindowHider's timeline, from the Document class? The WindowHider class is animated and rotates, thus the pixels show and the image is jagged. I know if I could access the smoothing property it would solve the issue.
Just 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. I tried to trace the stage from my document class and it was null when the tlftextbox was on the stage but i could trace stage correctly when I deleted the textbox. [code]...

I have a "box_mc" movieclip on the root of my stage and I need to select it from within my Document Class. I thought Stage.getChildByName("box_mc") would work, but it just returns null.

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?

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?
View 2 RepliesIs there a way to get an instance reference to the document class to call a method of it from the stage's timeline?I see that here's a possible solution: using a singletonOther solution I though of is using stage.getChildAt( 0 ) but it's not very nice.Is there an 'official' instance reference? because the document class is obviously instantiated at startup, but is that instance accessible in any way without having to use a custom solution like the ones mentioned?
View 1 RepliesI have created a game in flash, and due to the nature of the game, I have many movieclips placed on the stage manually in Flash CS4. They are not programmatically added as children to the stage, and so I am having difficulty getting access to them in the document class. So far the only method I have been able to use is to do stage.addChild(active_area); (for example), but there are many movie clips, all very differently named, so this method seems incorrect.I've discovered that my MovieClips are not children of the stage, but in fact MainTimeline, as when I for loop through stage.getChildAt(i);, only one child, root1, is traced out. How can I access movieclips that were placed on the stage in the timeline from the document class, without having to manually add them as children to the stage? So it looks like my problem wasn't that I couldn't access the MovieClips, it was that I wasn't modifying the MovieClips' values, so I wasn't registering any change in them.
Here is the code after I fixed it:
function manage_cursor(e:Event):void {
prevX=currX;
[code].....
I'm trying to access a text input that I've already placed on the stage (inside a movie clip) but with no luck.I've defined an instance name for this dynamic text field which is currentUserCount.I've got something like this set up in the document class actionscript file:
package {
import flash.events.Event;
import flash.net.URLLoader;
import flash.net.URLRequest;[code].......
What am I missing? When I run this I get:
1120: Access of undefined property currentUserCount.
1120: Access of undefined property movieClipName.
1119: Access of possibly undefined property movieClipName through a reference with static type flash.display:DisplayObject.
1120: Access of undefined property currentUserCount.
i know this may seem kind of dumb, but how does one access the document class from a child movie clip on the stage?
i have a property in my class. Just a string for testing:
Code:
public var s:String = 'can you see me';
it traces on the root time line, but it errors out if tracing it from a movieclip on the root time line.
I have a document class that looks like this:
Code:
package
{
import Map;

Is it possible to access a property of the Map class (though map defined in the Document class) from within the hero class?
The Main.as file will have all of the game logic, such as the mysteryNumber.
The other actionScript files represent rooms that the user may click and depending on the 'mysteryNumber', it will execute the 1 of 6 scenarios.
So for example, if a user clicks the Library page, the LibPage.as will call the 'mysteryNumber' and execute some code to display on the library page.
It will be the same for the other 4 rooms.
The problem I have is that the LibPage.as won't call the 'theNumber' property from Main.as
Here's the Main.as
Code:
package
{
import flash.display.MovieClip;
import flash.events.MouseEvent;
[Code]....
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.*;

This is my first time trying to use document classes in AS3. I am trying to add event listeners to a 2 levels deep movie clip, waiting for a click however I am getting the following error.

Is there a way to refer to a Movieclip on the stage from a class file of the document class
Lets say I have 3 MovieClips on the stage(a Circle, a Square and a Triangle)
I have the document class which calls another class that controls the MC on the stage
Example
ActionScript Code:
package {
public class Example extends Sprite {
//Create the instance of the class being called
[Code]....
in AS3, I have an external class ImageLoader, that loads an image upon request. In that class, I have an event handlers:

I am trying to send the download progress updates back to the main Document Class and display it on screen, so I am trying to dispatch the event "PROGRESS_INFO" and then get the information from the passed Event Object, like so: Document Class
[Code]...
This however, is proving futile... any ideas on how I can get the progress info out of the IMageLoader class? note: I know I can add bytesLoaded & bytesTotal to a public variable, but then I won't get the benefit of seeing the bytesLoaded property update in the ProgressEvent class.
If I have three classes:
public class Example {
public function Example () {
}[code]............
You can see that the two last classes extend the first one, and both have the 'variable' property. In case that I have an instance of Example and I am sure it is also an ExtendedExample OR AnotherExtendedExample instance, is there some way to access the 'variable' property? Something like
function functionThatReceivesAnExtendedExample (ex:Example):void {
if(some condition that I may need) {
ex.func()
I'm being really dumb today and I know this should be simple.....How do i access the stage from a class which isn't the Document Class? For instance, I want to create a tween which takes in the parameters of the stage's width? So I've written.....
ActionScript Code:
var myTweenX:Tween = new Tween(this, "x", Regular.easeOut, this.x, stage.stageWidth, 60, true);

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.
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.*;
[Code]....
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?
