ActionScript 3.0 :: Return Value From An Event?
Jan 5, 2010
In my main i am trying to return the value of what is inside the text file applied to the value terrainArray.
Code:
levelData = l1.GimmiData();
If i try to call the method it will return the value i first declared of the Array. I have wasted a few days of reading trying to figure out ways to get this value back to the main and as an Array as other ways i have tried give me Implicit coercion errors. Ive tried many different ways and the code below has changed many times. I even thought of using a psuedo threads style approach since it seems the value is called before load finish's but i could not get it to work. My java style approaches have failed miserably.
Code:
package scripts.levels{
import flash.events.*;
import flash.net.URLLoader;
[Code]....
Note: the .txt file is plain text and for this simple .txt file xml will only complicate things. At most there will only be about 20 words nested in the txt file.

I have an event that hits a web service and returns an array, i've built this into a public class. The web service returns the array through a result event, however what i want to do is return that array back to the component that made the initial call but i can't work out how to do it.
If i put a return on the class function it doesn't work as the array is returned in the result event, but if i put a return on the result event it doesn't return the value back to the initial component.[code]...

I'm trying to make a small piece of code that I can use on many projects. The idea is to send a couple variables to a server (username and score) and then read from the variables the server sends back. The problem is, I'm trying to send the score with the constructor function and want to access a member of the object to get the response variables. This works except for the fact that I don't have the variables until a Event.COMPLETE event. Here's the utility:
Code:
package com.insomniaque.utils {
import flash.display.Sprite;
import flash.events.*;
[Code]...
Unfortunately, the problem is that the trace simply returns "null". If I put the trace inside the SendScore/sendComplete function, it works fine.
I was thinking maybe if I kept the constructor from returning until the sendComplete finishes, this would work, but I'm unsure of how to do this.
Also, on another matter: How would you guys suggest preventing users from tampering with the data with tools such as the extension TamperData?

I'm editing an xml gallery.you can see how it works now here (thumbnails are different than images, cause it's just for the sake of testing now)[code]...
oki. this all works via for each loop which creates thumbnails dynamically. the event handler for the click on the thumbnail is inside the - also dynamically created via this for each loop - button over each thumbnail. more or less like this[code]...
and now: i'd like to add "next" and "back" buttons,so that the user doesn't always have to click the closing cross and go back to the thumbnails, but that he can also -once he selected an image - simply loop through the gallery image by image.
oki. so first i tried to get the name of the button clicked previously and store it in a variable, a thus this would tell which image should be loaded via loader (say, name instance56 means Image00002 was loaded, so if now user clicks next, Image00003 should follow) . but i'm simplytoo simple to get the variable out of the event handler and for each loop scope. i also tried to do it inside the event handler,but then it gets terrbily messy, and i can never force loader to load the right image.

I have an event listener applied to an xml load and it currently traces out the values it grabs which is fine, but what I want it to do is return an array for me to use. I have the Array creation and return working from "LoadXML" (it returns the array) but I can't get this to work with an event listener.The event listener runs the "LoadXML" function fine, but I have no idea how to take the returned array for use, this is an example of how my event listener works right now:xmlLoader.addEventListener(Event.COMPLETE, LoadXML());and my assumption of how I would take the array (this doesn't work):var rArray:Array = xmlLoader.addEventListener(Event.COMPLETE, LoadXML());so instead I tried the following:
xmlLoader.addEventListener(Event.COMPLETE, function():Array{
var rData:Array = LoadXML(datahere);
return rData;

Actionscript is really stressing me out! My code is too messy to post as I have tried everything from design patterns to procedural approaches. In short, is there any way i can retrieve my XML data in a variable after loading the URL request?
var req:URLRequest = new URLRequest(url);
this.loader = new URLLoader(req);
this.loader.addEventListener(Event.COMPLETE, readXML);
Basically I am trying to capture my XML output so I can place it a list. There doesn't seem to be a way to assign it to a variable without it losing scope when the event is over.

I am attempting to build a generic XMLLoader class with a static LOAD method, with the intent to use it as follows...
private var _data:XML = XMLLoader.LOAD("path/to/xml_file.xml");
Then I could use it in any client and go-to-town with e4x.
The general problem I am having is with the URLLoader's COMPLETE event, which necessarily calls a different function to set the XML data.This is preventing me from being able to return the XML from the LOAD method, since the data is being set outside that function. Obviously I need to wait for the COMPLETE event in order to make sure the data is available.
I though, perhaps, I could create and return a _waitForData function, which recursively calls itself until the _data is set, then returns the data. But it seems redundant (since Event.COMPLETE is doing that anyway), and the way I tried it generates a stack overflow error.[code]...

I have an as3 class that I use for communicating with my Zend_AMF endpoint:
[Code]...
All of this works fine, but it takes a lot of work to use it. I always expect a Response object when calling send() on my request. Ideally I would like to be able to call request.send() and have it return a Response object directly and not having to deal with a listener: var result:Response = request.send(); Is this possible? If so, how can I go about doing this?

I can't think of a way to write a function that returns an object that is loaded from an external swf. I need to be able to make a function that waits for an event listener before returning the value. I want to be able to create objects that can load in external swfs with minimal and no redundant code.
Here is the over all logic of my function:
Code:
//First create an object and set it to function that loads in an external file
var MaskFrames:Object = loadFile(parentObjectName, "swfs/", "file.swf");
//Create the function that returns the loaded swf as an object

I am trying to write functions as efficient and reusable as possible. One function in particular I wrote was designed to easily create new objects from externally loaded files. The problem I have is that I can't think of a way to make the function wait for an event listener to complete before returning the desired object. Here is what I have so far and I will point out where the problem is.
Code:
var myNewObj:Object = loadFile(parentName, "swfs/" , "file.swf");
function loadFile(parentObj:Object, urlLocation:String, fileName:String):Object{
var fileLoader:Loader = new Loader();

I want it to return a MovieClip but only after a Loader has triggered its COMPLETE Event.
like so;
Code:
static public function loadBitmap(URL:String):MovieClip {
// create MC
// create Loader
[Code].....
but it isn't fool proof because the MC is returned before the Loader finishes loading.

I'm having some troubles with the use of interface and inheritance in AS3. I've done lots of OOP in the past and what I'm trying to do seems obvious to me, but doesn't work in AS3. The question is : Is it possible to override a function that return an Object of class A, and make it return an Object of Class B which extends A ? It seems not to be possible, since I'm getting a signature error in Flash, when compiling. For example, the following set of class do not compile (the code in function definition doesn't matter):

I hava a custom component and it contains a child icon. If I add a mouse-click event listener to both component(click-listener1) and icon(click-listener2), the event dispatched sequence is click-listener2, then click-listener1. I can understand it. But if I add a custom event to component (listener1), and mouse-click event to icon(listener2), when icon is clicked, the component will dispatch the custom event. In my test, the event dispatched sequence is listener1, then listener2. It doesn't match with event-bubbles rule.
In my opinion The custom event is dispatched in listener2, which triggers listener1. Why event flow sequence is not listener2, listener1?
In component.
icon.addEventListener(MouseEvent.CLICK, iconClickHandler);
private function iconClickHandler(event:MouseEvent):void

I am trying to learn JavaScript and I am wondering whether JavaScript has a event listener just like ActionScript's ENTER_FRAME. Basically, I want this event listener to listen "all the time" not just wait for any particular instance (mouse click, keyboard event) of event.

The app I want to build is an interactive map for a site I'm designing. In a nut shell, students looking to enter an exchange program should be able to use the map-image (as in, an actual 'map of the world') to preview possible destinations (I've attached an image of the two basic states to clarify).
After an introductory animation, I want a mouse-over to trigger a function that populates the map-image with a series of buttons. I need the buttons to be distributed according to information in an XML file (ie. x/y coords, some information text, and an animation to load upon being clicked). I want each button to call a mouse-over function that loads info data from an XML field and place it in a dynamic text field at the top. Then, I want each button, when clicked, to call a function that animates replacing the map-image with an image of the corresponding travel destination. Finally, I want a button on each image that will clear that image from the stage and call the function that populates the map so the process can start again.
I'm working out of a couple of books on AS3, but I'm a little hazy on how I ought to be constructing this thing. So here's the first place I've run aground: After the intro animation, I want the user to mouse-over the stage and have a second animation play (clearing away the introductory text), and I want the conclusion of the clearing animation to immediately call the map-populate function; but I don't want a mouse-over to have any effect until the introductory animation is finished. Is there an event dispatched automatically at the end of an animation? What is the event listener class?
I'm not sure if I should be storing each of these animations in an independent .fla file or if I should create them on all one timeline and have the program redirect to specific frames.

I know the difference between the two, but I never felt the need to use the bubbling feature. If I want to listen to an event from a deeply nested children, I always use the capture phase. Could someone explain to me why I should rather use bubbling, its advantages, and maybe show me a situation in which bubbling would be the only solution?

i have a question to ask about asynchronous key controls This was what i did
[Code]...
and i checked with [URL]...?newspage=6249 and it looked more or less the same, so why is it that when i move my character and when i hold down a key, it just keeps on listerning to that keypress event listener, instead of just executing the other event. So say, i tap left and after which i tap right, it will work just fine, but if i hold left and tap right, the event listerner will still be listening to the left key. So, i was wondering could anyone point me in a direction as to how should i make my code stop listening to an event as soon as another event has been dispatched?
