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.*;
[code]......
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 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.
View 2 RepliesLet's say I have a FLA file with document class called main. In main, let's say I have a method called test1 that just outputs "hello world" via trace. On the FLA I have a movie clip. In that movie clip, when the timeline reaches frame 123, I want it to invoke the test1 method (I just set up a simple action on the frame). However, I get an error saying that the method is undefined. I try this.parent.test1() too but that gives me the same error. Is it not possible to invoke a document class property from within the timeline of a movie clip that's on the stage?
View 2 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;

I am developing a Jigsaw puzzle in Flash. I am developing a class for puzzle piece. The code of the PuzzlePiece class in given as follows.
package

import flash.display.MovieClip;
import flash.events.MouseEvent;[code]....
I will be choosing which mask to use based on users selection of puzzle piece.When I try to use traingular mask by adding puzzle.gotoAndStop(2) the swf just flickers. Thought the holder_mc and mask_mc are exactly of same dimension one comes below lower than other though I have not altered the position of the clips within a puzzle piece.If you want to take a look at my fla here it is https:[url]....How to go to a specific frame 2. Why is position of two clips inside the piece changing
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.
If I have a Document class that extends MovieClip, and I want to use it as the basis for another Document class, is it possible to create a subclass that extends the main document class and use that for a different FLA?
For example,
fla1.fla has a document class of MyMainClass:
public class MyMainClass extends MovieClip
fla2.fla has a document class of MySubClass:
public class MySubClass extends MyMainClass
I've tried, but now I'm getting errors that all of my variables that reference stage instances aren't being found.
Ok, this is one of those walls that I know once I can jump over it, I will be a much happier developer again.
I've done tons of reading, and think I have a firm understanding that the general consensus is that if you want to reference something, it needs to be added to the display list, using addChild().
I hate to be defiant, but what if I don't want to?
Or at the very least, what if I want to add a movieclip class to the stage using addChild, and then reference objects inside it?
It is much easier this way than what most people recommend - adding 15 objects via addChild, then setting the x and y for the, etc.
That said, I'm all about using classes and using as3 the way it was meant to be used. So what this is, is a best practices question I guess.
HERE ARE THE STEPS I'M TRYING:
- Create new flash document
- Draw graphic symbol bg, with text field over it, select them, convert to movieclip symbol, and export class name "box", then delete it from stage
- Add document class .as file, which simply adds that class "box" from the library, to the display list using a simple addChild()
- Set a name for that box using box.name = "test" let's say
- Do a simple trace like the following - "getChildByName('test').textFieldName" - it shows up great
- So then, I'll now try to set the text by doing this - getChildByName('test').textFieldName.text = "yo";
That last line above, is what doesn't work. I know I'm referencing wrong, but how would a pro as3 developer, reference something on the stage within a movieclip class, from the document class?
Is there a way I can reference a Movie clip I have on the main stage from a custom class of a document class?[code]
View 1 RepliesHow can I run function of the main document class from a class of a MovieClip? I usually just used MovieClip(parent).function(), but now my MovieClip has another parent. Or what do I have to pass to the MovieClip class when creating the MovieClip to acess the main document class?
View 9 RepliesIs 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

I am dispatching an event from one document class and listening for it via another document class.My code in class A.
Code:
this.dispatchEvent(new MYEvent(MyEvent.APERTURE_DONE));
trace("Dispatching APERTURE_DONE");
my code in class B.
Code:
addEventListener(MyEvent.APERTURE_DONE, onDoorsOpen,true);
trace("Lisetning for APERTURE_DONE");
[code]....
My listener is registering before the event is dispatched, based on my output window, however I never get the "Open Doors" trace statement to fire.
I have a FLA (say Main.FLA) document class with a child MovieClip on the stage: into the child MovieClip I load other swf files: each of the files contains its own Document Class (every swf is a somewhat independent application, say quizzes and so on).For some reason I must use the Main document class to store data (scores or so) from the child swfs loaded into the Main swf. HOW do I reference the Main class? I can't find a way.[code]and dispatch an Event this way from the loaded swf document class to the Main class:[code]Now, first of all I don't know if this could even work. Secondly, I tried to make it work by adding an event listener to my Main class but id did not work.
View 9 RepliesGot 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{

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 2 RepliesSo I had a working .fla, with a document class package in the same directory. Everything was fine, until moving both to a new directory, now the fla cannot find the document class. WTF?
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 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?
[Code]...
I often write apps in flash where I wrap all the display elements into one parent display object container (not the stage). Let this parent container be mc_world for example. I declare this in my Document class (Main) as:
ActionScript Code:
public static var mc_world:MovieClip;
Since this container is unique and often times needs to be referenced from various classes in the project (that are not its children) I find myself often doing Main.mc_world across my project to access this container.
Is it bad practice to directly access static members of the Document class throughout my project? Are there any simple alternatives? I don't want to dispatch events every time I need to access mc_world. And using a singleton class doesn't seem all that different from the Document Class (which only has one instance right?).
