How do I implement a listener within a class? I am instantiating other objects within side of another class. A sorta parent and child thing. How do I go about making the parent class subscribe to the child class. I want to leave all of the coding at a class level and keep it off of the main timeline.
View 5 RepliesI have this keyboard event listener to listen for key_Down of letter A and D but I end up with and error:

Can I implement more than one interface to the same class?One option is to make interface A extend interface B and than have my class inplementing interface A. Is there any other way that I can implement two or more interfaces directly to the same class?
View 3 RepliesQuick question. Does a class have to implement a interface directly to be accepted, or can it be a child of a parent class that implements it. so If I pass a child object into a method that only accepts IOBJECT, but the child class parent implements IOBJECT. will child object be accepted ?
View 1 RepliesI made a class in AS3 for representing complex numbers. It does not inherit anything. How can I enable casting from e.g. Numbers? I.e. I want this:
5 as Complex
to be the same as this:
new Complex(5);
is there a magic cast() function I can put in my class?
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 know actionscript does not allowed private contstructor at any time and But if i want to write a sinlgleton class in action script So how to implement it in actionscript.
Can anyone provide an sample example of a singleton pattern in actionscript?
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?
Is there any way of extending a class which is extending the movieClip class? Or generally a way to add extra methods to an allready existing class without having to add them in the actual class declaration. I was thinking of using Interfaces but how can I implement an Interface to a class which is extending a movieclip?
Code:
import interfaceName
class className implements interfaceName{
//stuff
}
But where do I put the code which extends the MovieClip?
Code:
class className extends MovieClip{
//
}
Actually, I already know the answer. The main reason I'm posting it here is for Google searchers, and if I copy and paste the post into my blog, my ActionScript code gets formatted all pretty, when all I have to do is add "as" tags here.

I'm having some trouble implementing a "virtual" camera for use in game development with Flash CS4 ActionScript 3.0.Basically, what I'm trying to accomplish is to have a camera that moves about the main stage so that my character can traverse the level which is much larger in size than the stage itself.I've been using Sham Bhangal's virtual camera script, and when I implemented it by sticking the code into the first frame of a movie clip, it worked great!
From there, I moved the code into a document class that i could instantiate and then drop onto the stage as a child.Finally, I wanted to have a main "builder" document class that would be added to the main stage as a child, and within THIS class I wanted an instance of the virtual camera. This is where I hit some obstacles.how to properly instantiate the virtual camera within the builder class which is then added to the main stage. I have a Stage reference that is being passed to the main builder, but I don't know where to go from here. To what do I add the virtual camera to as a child? To the Stage reference in the main builder class? To the main builder class itself?The main issue is that when I export my movie with the virtual camera added as a child to the Stage reference within the main builder class, it complains that I'm not allowed to access certain values.
Code: Error: Error #2071: The Stage class does not implement this property or method.
at Error$/throwError()
at flash.display::Stage/set x()
This happens when I try to access parent.x from within the virtual camera class. I assume this fails because "parent" from this perspective is the main builder class, but using the Stage reference produces this same error.I am, of course, willing to provide more detail if something I've written is confusing, and I will gladly provide a detailed fix for those seeking to use a similar solution in the future.
To start - its best to say im new to Flex / OOP in general. I have been trying to add a custom class based on StrokedElement in order to implement a simple grid (not like the existing Flex Grids - this would just be for display - not holding elements etc...)
My current class looks like this:
package ui.helpers {
import flash.display.Graphics;
import spark.primitives.supportClasses.StrokedElement;
public class SGrid extends StrokedElement {
public function SGrid() {

So I've been trying to move the stage's X and Y position and keep on getting this error:

As for why I'm trying to move the stage, I have a movieclip which moves according to keyboard input and i want the stage/Background to always center on him.
I have a java class which has been deployed as WAR web application in a BlazeDS/Spring server sitting on JBOSS. Apart from the Flex application which will access the WAR file, I also need to start some server side process's which will initiate BlazeDS "pushes" to the Flex client via AMF messaging.
What is the best way to implement this server side process? - Should it just be a class with a main() method in the WAR file which gets called from the command line? Can this be done - not sure you can run a class in a WAR file from command line? - Should it just be a class with a main() method in a JAR file which gets called from the command line? Not sure what the standard practise here is. The key is that the process needs to be started on the BlazeDS server to push data out (not on the Flex client).
i am trying to define a button state class where i can give the class some params and have it load a thumbnail (large files were a previous problem for me on this) that will be displayed upon rollOver. i'm having some troubles with a couple of key points:
1. i don't know how to pass in a reference to a movieClip that i can refer to in order to change its state (x location, for example) 2. i don't know how to send a status message to the host script (main timeline AS code will need to deal with such a message) after the img has been loaded
*both of these would REALLY help me understand some of the mechanics involved with AS2 OO programming,

I've got a custom mxml component that currently implements IResponder. Passing this IResponder to a function works fine using this. This, however, includes implementing the public methods result and fault, so I'm asking if it isn't possible to pass a new IResponder to a function, somehow like this: object.function(someProperty:String, new IResponder());

Im tring to remake most of my projects that i've created so far in class's and packages but it seems to be a mission.
I have the gameMain_Controls class which is the linkaged to the actually fla.
then i have a custom cursor class and a char class the gameMain_Controls pulls objects into the stage as children of the background fron the char class.
now my problem is to get the cursor to hittest of mouse over and at least do a trace out put:
code im trying at the moment which is also in a different class ...called the rollOver_Controls:
if (flap_Control.flap.hitTestObject(Dino_Control.layla))
{
trace("lal hit");
}

but the hittest jsut never occurs im guessing the problem is which the location of the object, the container i mean ...but when i try to link it that way i get even more problems

I have instantiated a class (class1) that loads some data via PHP in an AS3 Flex project.I instantiate class1, which is asynchronous and utilizes a URLLoader() to obtain its data.Then I would like to instantiate class2, which needs to USE the data from class1, but when I simply instantiate it I find that class1's instance variable is not populated yet because I am calling class2 too quickly.How can I create such a dependency that will link correctly?I am really new to using listeners, but I am imagining a listener in class2 might be what I need?Or maybe I can pass a reference to the listener in class1 into class2?I also know nothing about dispatching events... is this the key?Here's an example in pseudo code:
var class1:myC1 = new myC1("http://some/url/to/utilize");
//this never shows up because it hasn't loaded at the time i request it
trace("the stuff from class1 is: ", class1.myXMLList);

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

classfile2.as
public function buttonClicked (e:MouseEvent){ trace ("hello");}

The problem is that the action listener seems never get called when I press any keys. the trace() is not called. But I tried to add a mouse listener just to test and it worked.

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?
