I have a pretty good handle on dispatching from classes other than the Document Class, but what happens when I want to dispatch an event from the Document class and have other classes listen to the document class broadcast?
It seems like there are several ways to approach this (i.e using a Singleton, using composition, using MovieClip(root)) I was just wondering what people find is the "best practice" way to do this?
I have a document class called Main.as In the class constructor I have the following listener:
enter code here
var listeningFORModeChangeToStudent:Sprite = new Sprite;
listeningFORModeChangeToStudent.addEventListener(TellAllModeChangeToStudent.STUDENT,exp);
addChild(listeningFORModeChangeToStudent);
[code]....
In a third class I make a call to the despatcher in the previous class:
enter code here
var ThisTellAllModeChangeToStudent:TellAllModeChangeToStudent = new TellAllModeChangeToStudent;
ThisTellAllModeChangeToStudent.tellAllModeChangeToStudent();
I have trace statements in eveything and from this I know the despatcher in TellAllModeChangeToStudent is being called.The problem is that the listener in the main.as is not calling the function exp.I cant see why and I dont know how to check if the listener is actually seeing the dispatch event?
The dispatch even is not firing, what have I done wrong?
The document class:
ActionScript Code:
package
{
import flash.display.MovieClip;
[Code].....
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 1 RepliesI have a class which makes a url request and stores data from that request. When the data is retrieved, parsed, and stored into an array, I'm sending a dispatch event which I listen for in my document class. In the event handler function in the document class, I'm accessing the array that was compiled from the class. The array inside the class has 15 values, however in my event handler function, I'm only retrieving one value from it, which is the last value in the array. I posted my code below. Is there a different way I'm supposed to use the dispatchEvent in order to retrieve all of the array values instead of one?

View 3 RepliesI don't know if i've been in front of my computer for too long, but I can't for the life of me understand why this doesn't work:
All i'm trying to do is dispatch an event from one class to the other, when I trace it out, it says the event is getting added, but the event listener isn't picking anything up.

I am trying to dispatch an event of CustomEvent class
[Code]...
I have 3 files.
main.fla
PHP Code:
import classes.LevelObj;
var newLevel:LevelObj = new LevelObj();
var levelListener:Object = new Object();
levelListener.onLoaded = function(oEvent:Object) {
[Code] .....
Now this runs great but in the loadLevel function of LevelObj.as, when I receive the event from the GBXML class that it has finished loading I want to call another function within the same class (LevelObj) to continue with further processing the XML data. What I make of it, is that I am still within the scope of the myListener object. Should I use a Delegate function here to get to the function within the LevelObj scope?And how about properties from the LevelObj scope? When doing a simple trace of some testVar I get undefined. Logical ofcourse because it is not within the same scope. But I am stuck here.
This is the part that should contain the call to the function..
PHP Code:
myListener.onLoaded = function(oEvent:Object):Void {
trace("LevelObj.XObj > "+oEvent.success);
if (oEvent.success) {
trace(testVar); //CALL FUNCTION HERE IN SCOPE OF LevelObj
} else {
What I want to do is to dispatch the click event when the component is clicked. (The class is essentially some text in a textfield that needs to be able to do certain things, and it needs to be able to respond to a click). Sounds easy enough... I want the event dispatched when that portion of the text is clicked. But uh...how? it's not like a button where I can just go myButton.addEventListener(MouseEvent.CLICK, myClickHandler);That's clear, because some component is going to be listening for the Click event dispatched when myButton is clicked. It is built into the AS3 framework that a button knows how to listen for a click event.
After the import statements I've got:[Event(name="click" type="mx.events.Event")]How do I dispatch the event when the component is clicked, when the component doesn't yet know how to respond to a click event? I've tried adding an event listener in the textfield which contains this custom class of text, but nothing's happening because the Click event hasn't been dispatched.
I have an <mx:Application> which contains a <mx:Module>. This module has several child modules. It also has some an instance of a class I have created. I am trying to have a method of this class dispatch an event that can be "heard" by the module and handled. This isn't happening.To be more clear, I am using 'dispatchEvent' to from inside a class method.There is an instance of this class in: mx.core.Application.myapplication.mymodule.myclassIt is the 'myclass.somefunction' that dispatches the event. I have a listener registered in 'mymodule'. Nothing happens when the function/method runs, however.
View 1 RepliesI have small swf as3 flash applications that are loaded by a main flex application. The main Flex Application contains an SWFLoader and i added an event listener on SWFLoader.content to fetch custom events that I prepared.
now whenever I like in the application I use the function dispatchEvent to create the event and I make sure that the bubbles parameter of the event is true. so in this case the event bubbles up in the stage until it reaches my event listener and I can handle the event properly. the problem resides when I have a static class and I want to dispatch the event from there. because it's a static class and not a display object that appears on my stage it has no where to bubble to and because of that I cannot fetch the custom even in my main flex application.

If I am not mistaken in order to dispatch a message from a class you need to extend EventDispatcher. What happens when you are already extended the class from a different class? Is there no way to dispatch messages?
View 1 Replieshow i need to dispatch an event from a class that Extends a movie clip now so i cant extend the class to be EventDispatcher. Do i need another class just for handling events?
View 3 RepliesI have a SendData class that sends form info to a php script. It is a static class that does not extend anything.
I want to be able to dispatch an event if there is an error, or when it gets info back from the server. I have a custom event class that I have been using to dispatch events like this, but I have only used that in displayObject extended classes.
The problem is, it seems like something has to be a displayObject based class to dispatch events. I know there must be a way to do this, but I'm having trouble finding it in searches.

View 2 RepliesI am trying to work with the EventDispatcher class to dispatch a custom event to stop a video from playing. The video plays inside a MovieClip with an attached class file called PlayerProfile. I want the video in the PlayerProfile MovieClip to stop playing when the user clicks on another MovieClip called ScrollBox. I'm getting no compile or runtime erros, but the code is not stopping the video. I have seen use of a public static constant to represent the custom event. Is that what I am missing here.

Imagine you have a MC used as a container for several other MC's used as buttons.Now, should I use the class of the container to listen for and to dispatch events. OrShould I create a seperate class for each MC inside of the container to listen for and to dispatch events.
In summary: One class for all, or several smaller classes dedicated to their respective MC.How far should one go with abstraction?.
Using Flash CS5 Professional I have created a symbol, dragged it onto the stage, and given it an instance name of GreenLight1. If I want to make this visible from the document class, I can simply do the GreenLight1.visible=true; and poof it's good to go when I test the file. As long as I stay in the document class I am good to go, but now I'm trying to move to another class and hitting ALL kinds of trouble just trying to get Flash to allow me to access this simple object. All I am looking to do is have this GreenLight1 go invisible (visible=false) when a certain condition occurs in this new class and Flash just won't let me access GreenLight1 at all. Things I've tried thus far:
stage is passed to the class and is referenced by _stage and is working just fine when I do _stage.addchild or anything like that. So I have tried "_stage.GreenLight1.visible=false;" and I get "ReferenceError: Error #1069: Property GreenLight1 not found on flash.display.Stage and there is no default value." My document class extends Sprite, so I figured I'd try the root function. So I tried "Sprite(root).GreenLight1.visible=false;" and I get "1119: Access of possibly undefined property GreenLight1 through a reference with static type flash.display:Sprite." I tried to create the Resource class as described therein. To which I came across the same problem that I started with in that it doesn't know what GreenLight1 is to begin with so I got "1120: Access of undefined property GreenLight1." Here is my code for Resource.as (am I supposed to pass something to this class from the document class?)

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.
while working with a server side script (php or aspx) which returns some data(from the database) can we call it in a sub-class or do we have to make the calls in the document class itself?
View 2 RepliesSay i need to send some data from AS 3.0 to a server-side script for it to do some actions. Can I do this in a sub-class called some where in a document class or should we always do it in a document class?
View 1 RepliesOk, 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?
i have a movie clip which is exported for ActionScript , i want to get a variable from the document class into the movie clip class i tried this but there was an error !!
ActionScript Code:
var main:Main=new Main();
main.txtScore.text="hello";
I have a custom class created by a main document class, and I want the custom class to run a function in document class after some time.
How can I sent the instruction from custom class back to the document class?[code]...
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]
