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?
how to add an event listener to an event from a custom class. Here are the relevent lines of code (I think) from the class:
[Code]....
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 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?
I'm trying to create an Event Listener used with all buttons placed on the stage rather than a listener for each button object.Are coding examples of a class listener?
View 5 RepliesFor 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.
[Code]...
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:
package
{

I am having trouble getting a simple event listener class to work. The class is:
Code:
package {
import flash.display.Sprite;
import flash.events.*;

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.
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?

in my class I am trying to add a MOUSE_UP event listener to the stage.How can I do this?

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.
View 15 Repliesi have got all my public vars for sound class but im having trouble on how i would execute them because i normal would use event listener but its OOP lol so how do you get that functionality ?code in star.as file:
package {
import flash.display.MovieClip;
public class star extends MovieClip {[code]......
Or do you have to add them to every instance?
View 5 RepliesI 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 have question regarding removing instantiated objects. Let's say i have a main class in which i instantiate a custom video player (or whatever) class:
Code:
...
var videoPlayer = new VideoPlayer(...);
addChild(videoPlayer);
...
And inside VideoPlayer class i have of course dozens of objects (movie clips, sprites representing different parts of VideoPlayer) and dozens of event listeners attached to them. My question is, if i want to remove this VideoPlayer class from my main class is it enough to just do:
[Code]...
I have a initApp.as which instantiates a class which needs to access the "currentState" property and the States array as well. However we cannot get this to work as we cannot see how we can access this information.
Within initApp.as currentState is accessed via "this.currentState". This does not work in the class which is instatiated within initApp.as. The following error is thrown:
"Access of undefined property currentState."
I'm wondering if anyone has experience with if there is a big difference in performance in ActionScript 3 between keeping a class with only public static functions, and utilizing those functions often (as in a frame event at 30fps), and in turning the class into a "normal" class of which I instead make an instance and call the functions via the instance instead.
View 1 Repliesim trying to create a separate class so i can create a custom mouse. But i need to make it so that every time the mouse moves then something happens. as in it dissapers and after 5 seconds the timer resets. I have the code and it works in my .fla file, but im not sure its possible to put it in a class file and have it be the class of the .fla.

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?
Im getting an error whilst trying to add an event listener to a class of a Button on my stage.

I am making my way with AS3 in little steps and have hit a road block. This is what I have:
I have a document class called "Document Class" I have a custom class called "Game"
I have instantiated an object of "Game" class and I am able to trace a class method which return a simple "HELLO". within my Game class, I have a variable(type Array) called "questions" as instance variable.
I would like to add questions to "questions" array by using "Mutator" method, or count the current elements with the questions array and return the total number of questions. I am unable to add or access elements to the questions array.
I usually use if(object!=null) but it doesn't work well.
How can I verify if the class is instantiated. I want to get rid of the 'cannot access a property of a null object or reference'.
I mean, the 'var object:Object;' is just a reference to an Object class instance. When i initialize it with 'object = new Object()' it runs the code in the constructor, initializing it. How can I check if it has been initialized or not.
I've been struggling with this for almost a day now and I can't seem to find the problem. I'm making an instantiated FLV playback class in actionscript 2, but it just doesn't play the video
Here's the code, if I uncomment the camera parts and attach _cam instead of _stream it will show the camera feed, it just won't play my movie (and I get no errors whatsoever).

I know how to do this in as3, it's easy.
var c:myclass = new myclass();

how the heck do you do this in as2?
