ActionScript 3.0 :: Event Listener And Dispatcher - Send And Load Class
Jul 29, 2009
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've built a custom event dispatcher:
Code: Select allpackage com.tests{
import flash.events.EventDispatcher;
import flash.events.Event;
[Code].....
The event traces out that it successfully fired, but the listener doesn't catch it...

I have a ColorPicker Component and I want to (on its CHANGE EVENT) have the LISTENER OBJECT ( known as A) change ANOTHER OBJECT's (known as B) color, based on the ColorPicker's.selectedColor. I do this because i need OBJECT A to keep track of the colors used. Also OBJECT B is dynamic and its instance is based on USER INTERACTION thus B can equal B1 or B2 or C based on mouse click at any given time but must only be 1 at any given time. SO I'm trying to "chain" the events together using listeners/ or delegation but I'm not sure at the logic.how do i reference the objects in the event? should I just try to chain B to listen directly to the event? How can I do this without having to attach listers to the colorpicker every time?

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");

I'm programming a little tank game (Check the attachment). The main class for tank is game.serovkonstantin.tanks.Tank.as and there are also 2 subclasses for now: Abrams and T90 which extend Tank. In my game.serovkonstantin folder I have a custom event (TankEvent), and the only event type inside of it which is TANK_INACTIVE.
I've added an event listener for MouseEvent.CLICK to each of the tank instances (inside Tank.as) which works just fine. When I add any of the tank instance onto the stage and click it, it traces the tank's name just like I wanted whether it's Abrams or T-90 depending on what tank I clicked. But the problem is that when I click a tank I also want it to dispatch my TankEvent.TANK_INACTIVE. The main stage has a listener for this event, so I expected it to catch the event and trace some phrase, but nothing happens I don't know whether it doesn't dispatch my event or doesn't catch it.
========
if you're interested why I need to dispatch this event, well,I suppose it will help my game know what tank to move when I click somewhere on the stage, and what tank(s) should be inactive,event it they all of the same type. I mean if I click one of the tanks it accepts all the controls while the other should be inactive

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?

So I have two classes talking to each other with EventDispatcher. One is a thumbnail of an image, and when it's clicked, it sends an event to the other class to display the full size version. I'm using a MovieClipLoader instance to load the full version (and the thumbnail).
Here's how it's sending the event from the thumbnail class:
Code:
private function initButton () {
this.loadMe.onPress = function () {
this._parent.sendEvent();
}
[Code]....
The problem I'm having is it loads the full size version ONCE. After that, it no longer receives the event. The ("event received") trace no longer comes through. But the ("send event") trace continues to work.
The other weird part is if I comment out the loadClip, then the events come through just fine on both sides. But it's like after it loads an image once, it quits responding to that event ('onPhotoSelected'). Is there some kind of mis-communication between the events of the MovieClipLoader and my custom event or something?

I've doing a bit of "training" at working with Flex and Remote Data from XML files.This is my HTTPService
<mx:HTTPService id="loginData" url="com-handler/basic.xml" showBusyCursor="true">
</mx:HTTPService>
I have a button and when its clicked its call a function, that calls loginData.send and does a little IF condition, that IF condition relies on the data returned by loginData.The condition doesn't work because its called right next to the loginData.send, and .send method still didn't returned the values from the XML file. But if you click it a second time a second after the first click the IF condition works.So to deal with i wanted to do a eventListener so that when loginData.send returned the data from the XML it fires up the IF condition. But i don't know how to do it.

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. But event doesn't work when I test the move! When I move the event handler (buttonClick) and event listener to main class (test) and apply the event to the card object (for example), all works fine.

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 have two movieclips: MovieClip X and MovieClip Y.
MovieClip Y is nested inside of MovieClip X. MovieClip Y contains buttons with listeners attached to them. These listeners call a method
Code:
buttonClickedHandler();
inside of buttonClickedHandler();... dispatchEvent() is called to dispatch a custom event that bubbles up to MovieClip X. This chain of events works as intended, I can set up a listener in MovieClip X for the custom event and everything is fine...
The problem comes when I try to invoke a dispatch on a button in MovieClip Y without actually physically clicking it. If i call
Code:
ButtonA.dispatchEvent(new MouseEvent(MouseEvent.click));
the listener for the button click event will fire properly, and if i trace the dispatchEvent of the custom event, it returns true meaning the event was dispatched successfully. But in MovieClip X... the listener for that custom event is never fired, its as if the custom even is not bubbling.

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.

there are 2 functions in my code that dispatch a TweenEvent. each function dispatches the same tween and adds the same TweenEvent.MOTION_FINISH event listener. however, the event listening function must act according to which function dispatched the event. is it possible to get the function of the event dispatcher from the event listener? i could use a flag to make this work if there are no other elegant solutions.

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?
