ActionScript 2.0 :: Eating A Global Listener On The Class And Receive Dispatched Event For Any Instance Of The Class?
May 11, 2006
I've done a class to be able to listen to the event for a CLASS not on an instance.
Code:
class net.webbymx.events.XClassEventListener {[code]....
why did I do this.It cames with my rugby game.I have player in two teams. When a player throw the ball I want the other teammate to act like "wait for ball" and the opponent like "seek for ball". Plus I'm lazy (and I don't want to register the listener for each instance of the player I'm creating). So this class is made to be able to handle as many instance of a class I want without adding a listener on each of them. I'm just creating a global listener on the class and then I will be able to receive dispatched event for any instance of this class .so in my team I can do
Code:
XClassListener.initialize(this);
this.addEventListener("throw", "net.webbymx.game.Player", "wait");
and in my opponent team I can do
Code:
XClassListener.initialize(this);
this.addEventListener("throw", "net.webbymx.game.Player", "seek");

Can event listeners only be added to the class which dispatched the event? I ask because I want to have the logic for the listener on the main class, and the action is dispatched on click from a thumb which is instantiated in a scroller class. Kinda like this:
ActionScript Code:
pseudo code:
class main {
main() {
[code]....
This doesn't work. Why can't the main class listen for an event on the thumb class?

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?

If I change the value of a variable that two different classes can see (in a custom global class, for instance), and then immediately dispatch an event that the other class is listening for, will tracing that variable in the listening class reflect the variable's new value? In other words, does code that executes in another class that's called from a dispatched event elsewhere still run procedurally, or is there some sort of asynchronous thing going on, where the class that dispatched continues on to the next line of code in its own class without regard for what may or may not happen in the other class?

I have a main class which listens for an event dispatched from another class say class A. Also there are other classes say class B, class C etc.There is a controller class.Classes B, C dispatches events that gets listened by the controller and works well.But the events dispatched by the Class A doesn't get listened by the main class.What might be the problem. Detailed Explanation of the problem.There is a main mxml file.
Class files are in:
ProcessInput.as
DBController.as
ShortMemDB.as ....etc
The main mxml file gets the input from a textArea. Sends the input to the capturedInput (input:String) function using set method which is in the ProcessInput Class.Now I need to dispatch events NORMAL, COMMAND depending on the input obtained after the processing, where I'm having problems. The reason is that if the event NORMAL is dispatched a particular function inside the DBController is to be called. If COMMAND event is dispatched then I need to call another function. This idea doesn't work since the events doesn't get listened.But the events dispatched by the CSDB class when listened by the DBController works well.

I have the following situation:I have an event handler, that displays small messages in my application's statusbar.These messages get passes through by dispatching events from custom components.A simple message could be like "HTTP Error" or so.Now, the main event listener, in the main application file, listens to the event dispatched by any custom component,but seems to refuse listening to events dispatched by custom AS classes.Here is my code for the custom event:
package main.events
{
import flash.events.Event;[code]..
So to sum it all up:
- The event listener listens to the custom event dispatched by any custom component.
- The event listener does not listen to the custom event duspatched by an AS class.
Those who wonder, the event really gets dispatched, that's why I added a trace call.

I have a class file defined in my package as MyGlobals.as.[code] (I have tried adding/removing "static" and "dynamic" to no effect.)I am trying to call a touch event from the main timeline in this way:myObject.addEventListener(TouchEvent.TOUCH_BEGIN, MyGlobals.myFunctionName);(I have tried removing the class name to no effect.)When I compile I get the error 1046: Type was not found or was not a compile-time constant: TouchEvent. This error occurs on function definitions in the class file.What syntax/concept am I getting wrong? The functions were working fine when I was using constants in the timeline, but I need to be able to reuse these functions over and over again, so I wanted them to be able to take touch event variables so that I didn't have to write a different function for every touch event.I tried googling "error 1046" but I can't find anything useful.

I have a base class which is being created via remote_object [RemoteClass alias] from the server.I have other specialized classes that are derived from this baseclass, but serialization with the server always happens with the base class.The base class has meta data that defines what the derived class is, for example
[RemoteClass (alias="com.myco...')]

For graphical representation I use fla file as a resource. I work in Flash Builder 4.6 to code. I try to create own class Panel which contains the click event.

let's say that i have this button which is called "Click_Here" and i added an event listener to it in some class file in order for it to run the event handler in a different one .. so it will be like this
classfile1.as
Click_Here.addEventListner(MouseEvent.CLICK , buttonClicked ) ;
classfile2.as
public function buttonClicked (e:MouseEvent){ trace ("hello");}

I'm trying to add an eventListener to a custom class. I created a motion tween in CS4 and exported the motion as as3, which then gave me a chunk of code.I then took that code and turned it into a class. What I'd like to be able to do is set up an event listener in my FLA to listen for when this animation is done playing, however, I have been unable to get that to work. Do I need to add something else to my class? Is there something wrong with how I'm trying to implement the class in my FLA?Here's the code for the class:
Code:

I am having trouble getting a simple event listener class to work. The class is:
Code:
package {
import flash.display.Sprite;
import flash.events.*;
[code]...
and I have the ClassPath pointing to the folder that contains this .as file. I do get the trace "In setUp" but I'm not getting seeing any Keyboard events. There also aren't any errors showing up in output so I am kind of stumped.

What I'd like to do is add an event listener to a class instantiated by my document class that listens for different key presses. So far I can't use stage.addeventListener or I get the null object error so my question is:
a: how do i add an event listener to the stage from another class and b: is it even necessary to add it to the stage , can I listen from that class?

My problem is: I'm trying to create an external class which function is load an external sound file and play or stop depends on stage.activate and stage.deactivate events. The actionscript 3 in the timeline is functioning properly, but when I try to create as external class, it has so many errors. So many that I can't troubleshoot them. Btw, it's my first class creation. Is there anybody who kindly enough to give me some guidance to create a proper class with stage event listener?

I am using a component in my application, but it turns out, it's slowing my app down big time b/c it doesnt remove an eventListener on stage for mouse move. Is there a way I can remove this listener? I can't get into the class b/c it's a component and it doesnt have any sort of kill function to call.

I am developing in Flash Builder 4.5 using as3.
I have created a class to connect, write and read to a TCP Socket using 'import flash.net.Socket;'
Within this class is an event listener which reads the incomming data:
Code:
socket.addEventListener(ProgressEvent.SOCKET_DATA, readSocketData);
private function readSocketData(progressEvent:ProgressEvent):void {var response:String = socket.readUTFBytes(socket.bytesAvailable);
trace response;}
My problem is how to output this data back to my main application. Ultimately I want to process the data and output it in a text box.

I'm having an issue with an event dispatcher and an event listener. Here is the application code...
Code:
Select allpackage {
import flash.display.MovieClip;
import flash.events.*;
import flash.net.URLVariables;
import SendAndLoad;
public class Test extends MovieClip {
[Code] .....
It will trace the loader.data variables but doesn't dispatch the event to the main application (Test). I'm listening for the event on the stage of the main but it doesn't trigger the event to display that the login has been successful even though it traces from the sendAndLoad class...

I am using an external 'Animation' class to handle all animations in a project. I would like to register event listeners to listen for tween completion - how do I go about this?
function in Animation class:
Code:
public function SlideOut(target, tx){
var slideTween: TweenMax = new TweenMax(target,.5,{x: tx,y:0,ease:Back.easeIn});
}
[Code].....
Obviously, mySlide.addEventListener(Event.COMPLETE, transitionComplete) doesn't work. I've tried including the name of the instance of tween too but no dice. I could write my own event within the animation class and dispatch it via another function but there must be a more elegant solution?

I'm using a library that has a function that returns an instance of some class Engine.
I'd like to tack on some interfaces to Engine, so I subclass it class InterfacedEngine extends Engine implements AwesomeInterface. but when I change the code that uses the classes from this:
var engine:Engine = generateEngine();
to this: var interfacedEngine:InterfacedEngine = generateEngine();
It gives me a runtime error (elision mine):
TypeError: Error #1034: Type Coercion failed: cannot convert ...::Engine@1bc2bf11 to ....InterfacedEngine.
What about AS3 classes am I misunderstanding?

I have to admit I pretty much ran away from Flash when AS2 came along and only used it for animation purposes over the last 5 years.So I'm having a major crash course in AS3 in Flash CS3 and I'm not enjoying it one bit. I'm getting maybe 10mins of finished work per hour as I try to figure out the limits and rules of AS3. Quite often it seems that AS3 simply can't do what I want it to. Anyway: Characterchecks.as is the main class and it loads a bunch of XML into four arrays. The file starts like this:[code]If I trace the value of, say, cc._Categories from the main FLA, it's empty. I'm guessing that the next line of AS in the main FLA doesn't wait for the previously called function to complete? (This may tie in to my next problem)My next step is that I want to display various things based on the data in the array. I have another class, Display.as which will hold all the functions to create the items on display. I thought it would be best for these to be a separate object. I wonder if I'm right?
So I declare an instance of Characterchecks in the main FLA and call it cc, and then run the functions to populate the arrays... Now I create an instance of Display and call it cd. How can I get functions in cd to see the values of the variables in cc? And if the main timeline can't tell that the functions aren't finished filling the arrays, how is cd supposed to know?I might be asking dumb questions, or maybe I'm doing things ***-backwards, I don't know. I'd appreciate any help, I really would. This whole thing has me at the end of my tether... being the most technically advanced person in my circle of co-workers and web design friends means I have no-one to explain why things need to be done a certain way or what the best way is.
