ActionScript 3.0 :: Responding To Multiple Listeners?
Feb 2, 2009
How do you set up a funtions to run only when two or more listeners have been activated?For example: if one listener is waiting for a file to be loaded and another one is waiting for a display object to fade out.I want to get the object starting to load but also want to start the image on the stage to fade out at the same time.I want a new image to start to fade in but not before the new image is loaded and the old image has faded.

In AS2 you could add an onRelease to multiple buttons like this:
Code:
onebutton.onRelease = anotherbutton.onRelease = lastbutton.onRelease = function() {
//do something when either button is pressed;
}
Is there something similar possible in AS3 using addeventlistener? Besided copying the same addeventlistner line for all individual buttons?

I have a movielcip (A) class in which I have used a Tween class effect on a child movieclip (B) scrollRect. The (B) Movieclip in turn has several movieclips whose have tween class effect being executed on thier child movieclips.the tweens are all unique to each movieclip and the event listeners are taken off once completed.This works all well and good in FLASH IDE..My problem arises when I try to view this in a browser on a Windows XP.[code]
What is happening in most cases it that the animation appears to "stick" but i think what may be happening is the listening or removal of the event listeners. The animations are left incompleted.Is there any rule of thumb when using multiple event listeners?[code]the effect disables and re-enables the buttons when its done.... then the listeners are removed.each one with the exception cretes its own unique tween (obviously this is a custom class built as each clip)

I have assigned two event listeners to the same property:
full_loader1.contentLoaderInfo.addEventListener (Event.COMPLETE, fullLoaded1);
full_loader1.contentLoaderInfo.addEventListener (Event.COMPLETE, tweenOut2);
So far it works fine. I am just wondering if there is a hidden penalty that I am eventually to learn about.

i have a rookie question to ask and it's how to assign the same event listeners to multiple buttons in as3 instead of having to write out the same code over and over again like so...
ActionScript Code:
listing.home.addEventListener(MouseEvent.ROLL_OVER , butOver)
listing.home.addEventListener(MouseEvent.ROLL_OUT , butOut)
listing.home.addEventListener(MouseEvent.CLICK , released)

I want one PopUp to show up at (a lot) of different instances. And something unique has to happen linked to that instance so my thought is:
popUp.addEventListener(TouchEvent.TOUCH_TAP, instance1Handler);
popUP.addEventListener(TouchEvent.TOUCH_TAP, instance2Handler);
etc...

I am adding a different listener to each button in the menu and there are several menus as well, then each one of those functions adds a different child depending on the button and also pushes several values to the Array list, in this example called objectsOnStage. I will be running this structure function 40 times with each of the highlighted elements changing accordingly.
//Listener and function for Button01
menu01.button01( MouseEvent.MOUSE_DOWN, button01Function);
function button01Function(event:MouseEvent):void
{
[code]....
My original thought was to keep all those changing values in an Array list and run a loop for the function/listener, but I just cant make it go.

I've created a grid of 3D cubes using modulus, and the 3d cubes are were created from the Math and Flash tutorial. I have set up listeners so when the mouse hovers over a cube it starts to rotate:
private function setUpListeners():void {
spBoard.addEventListener(MouseEvent.ROLL_OUT,boardOut);
}
That works fine.
To begin the rotation of the cube when the mouse passes over it I have used:
private function boardOut(e:MouseEvent):void {
addEventListener(Event.ENTER_FRAME,rotateSquare);
var i:int = 1;
function rotateSquare(e:Event) {
renderView(curTheta+i,curPhi+i);
i++;
}}
I can see why this would be inefficient, as it is running the loop every every frame, and for so many multiple cubes it just lags (very badly). I should clarify, I'm hoping for the rotation to continue indefinitely once the mouse moves off the cube. Here is how I am creating the cubes onto the "grid":
public function FlowerMenu(){
var rowY:Number = 0;
for (var i:int = 0; i < 190; i++) {

I'm currently working on a nav bar but I've run into a questionable situation. There are several links in the menu, and for each i'd like a mouse event on over and on out. Do I have to specify both of these events for each link, or is there an easier way to do it that I don't know about? Can you apply event listeners to multiple objects/functions?

Scenario: Up to 50 instances of a display object are arbitrarily positioned on the stage.Is it better to create listeners for each individual instance or create one single global listener and then somehow find out which instance triggered the listener? If the latter is preferred,Will event.currentTarget tell which instance it was? And should I register the listener to the stage?

I have a mc which is 3 frames, with labels "Not Selected", "OverState" and "Selected". I add them to the stage with the first block of code, that is fine. The second block of code is my attempt to handle the states of the buttons. A selected mc goes to the correct state but it needs to go to "Not Selected" when another is clicked. My code does not do that. Also how do I handle the problem of MouseOver and MouseOut still working after a button is clicked?
PHP Code:
var numBtnArray:Array = new Array;
//add number buttons
function addNumButtonsToStage():void{
for(var i:int = 0; i < 4;i++){
var numBtn:numBtn_mc = new numBtn_mc();
buttons_mc.addChild(numBtn);

I'm following a simple tutorial on making a platformer, but I ran into a problem. This is the code I'm using in a player movie clip:
onClipEvent(enterFrame) {
if(this.character.hitTest(_root.bg.ground)==false) {
this._y+=_root.gravity;
[Code]....
When I press the keys, nothing happens, but if I replace the if statement with a 1 then the code executes fine.

im using this method to load movies and create transitions between them for my site.. I have read the technique thoroughly and im fairly sure the code and structure I have used is correct however the loadMovie function called from an embedded swf is not doing anything and I cant work out why..on the main timeline there is a container movie that the swf files are loaded into, the intro sequence is loaded through an action on frame 1:
_root.currMovie = "introsection";
container.loadMovie(_root.currMovie+".swf");
this works no worries.. but when the container is targeted from inside the introsection.swf movie nothing happens, this is the code used:_root.container.loadMovie(_root.currMovie+".swf")I have tried variations with this and nothing works.. the container movie has the correct instance name and the code works from the main timeline but not from within another swf.

I have content in a scrollpane which I would like users to be able to drag (content is larger than the pane). There are also rollover areas in the content that are only accessable when scrolldrag is false (makes sense). So, I've set the scrollpane scrolldrag property to false until the user presses the Ctrl key:
//Listener for Ctrl key to allow drag
createEmptyMovieClip('_keyListener',999);
Key.addListener(_keyListener);
_keyListener.onKeyDown=function(){
if (Key.getCode() == 17) {

I have some code that draws a line that follows the mouse and fades away over time, until now it was in the main file of my program but i want to make a class out of it for later use in other programs. I edited the code into a singleton MouseHandler class with one function that registers the mouse up and down events; with trace and 'hasEventListener' I found out that the events are registered but nothing happens when I press my mouse buttons.
Here is the class
package {
import adobe.utils.ProductManager;
import flash.display.DisplayObject;
import flash.display.DisplayObjectContainer;
import flash.display.MovieClip;
import flash.display.Sprite;
[Code] .....
In my main class I just use
MouseHandler.getInstance().startListening(this);

I'm debating two approaches to a pretty typical problem: Knowing when an event occurs or responding to it immediately if it already has occurred. In approach one, a user of MyLoader1 adds an event listener which will be fired immediately if the loader is already complete.
class MyLoader1 extends EventDispatcher {
private var _isComplete:Boolean = false;
public override function addEventListener(type:String, listener:Function, useCapture:Boolean=false, priority:int=0, useWeakReference:Boolean=false):void {
super.addEventListener(type, listener, useCapture, priority, useWeakReference);
[Code] .....
What advantages/disadvantages are there to each approach? Is there a design pattern out there that I could/should be using for this situation? I'm leaning towards the first because it requires less knowledge of the Loader class and less code to leverage it. It could potentially create unwanted side effects when there are multiple listeners though, because the event will fire once for each time a listener is added. The second method is understandable and easier to debug, but requires more up front work and seems to break encapsulation of the Loader.

I'm working with CS4 and AS3 using timeline coding. I have three sets of movie clips in three different arrays. The idea is to have topArray and downArray movies make zeroArray movies visible. For instance, if topArray[0] and downArray[0] are clicked, then r0_0 becomes visible. PROBLEM: r0_0 becomes visible when EITHER topArray or downArray is clicked. How to make r0_0 wait until BOTH top and downArray movies are clicked?
ActionScript Code:
//
//movie clips holdings results -- all invisible
var zeroRow:Array =[r0_0, r0_1, r0_2, r0_3, r0_4, r0_5, r0_6, r0_7, r0_8, r0_9, r0_10];
for (var a:int=0; a<zeroRow.length; a++) {zeroRow[a].visible=false}
