ActionScript 3.0 :: Multiple Functions/Listeners Similar Process?
Jan 13, 2012
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'm using the below code to have a button that adds a MC to the stage. The problem is that I have over a dozen of these buttons and I'd rather not have to write out the event listener and function for every single button. Is there a way to use a single function for all the buttons and just change what MC is added based on which button is clicked? So if the user clicks on the draw5 button the function adds the deck5 MC to the stage?[code]

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?

This is a bit of a crazy question, but does anyone out there know how to go about writing an extra compile step into the flex compiler. The idea would be that the MXML compiler would knock out the MXML to AS3 code as it does, but we have an extra step between the AS3 code and the bytecode.
The reason why I ask, is that this would be a great step to handle things like metadata tags to make code changes. A common practice in a lot of frameworks is to have an [Inject] tag before a variable. I.e. [Inject] public var user:IUser.

I have made an event listener:text0_mc.addEventListener(MouseEvent.CLICK, showMe);showMe is a function, but I need it to call more than 1 function at once i.e. -ext0_mc.addEventListener(MouseEvent.CLICK, showMe1, showMe2, showMe3, showMe4, showMe5, showMe6, showMe7);Each function contains an if statment as below.
function showMe1(event:MouseEvent):void

What I am trying to do is, if a user presses keyboard (key 1), picture 1 should FadeIn and if a user presses keyboard (key 2) picture one should FadeOut and picture 2 FadeIn and vice-versa. With the code mentioned below it works fine sometimes if I am not pressing any other key while it is performing one action but sometimes it behaves weird also. What I want AS3 to do is not to take any action or in other words it should not listen to keyboard until it finishes the opening or closing animation of a picture or any other object assigned to the key.
stage.addEventListener (KeyboardEvent.KEY_DOWN, KeyDownHandler);
/**///keyboard keycode for 1 & 2var key1:uint = 49;
var key2:uint = 50;
var BG1:Image1 = new Image1();
var BG2:Image2 = new Image2();

I've had this glitch for a long time, and I've tried several ways to get rid of it, and now that I just recoded everything to see if it was something I did, it's back again! basically, whenever I press space (regardless of whether or not I am listening for a space press [or any key press]), the last function fired by an event listener will run itself again, with the exact same arguments supplied to it in the first time.
For example, if I make a simple button to trace("text"); and take you to another frame. Once you get to that frame you can press Space and it'll trace "text" again! I really have no idea what's causing this, and it doesn't seem to be happening to me in new files. and there's too much code to show you, but I just want to know if anyone has heard of this before or if they have any theories to what's going on.

I have 2 functions. Each one is being called by a different event listener. Both event listeners work because I am able to trace strings in both of them.. my problem is that i am trying to create a variable that is local to both functions. The first function "working" adds a number to the variable and when the second event listener triggers function "notworking" which retrieves this same variable called "counting" both functions are called automatically by event listeners.. how do I do this? i am stomped!

I've managed to create a button which on MOUSE_DOWN scales its parent object- it works just like windows in your OS, where you grab the corner and can change the scale of the window.
Here's how I've done it, (minus the MOUSE_DOWN listener)
Code:
function scaleDragHandler(event:Event):void {
var mcWidth:Number = event.target.parent.width;
var mcHeight:Number = event.target.parent.height;
[Code].....
However, it throws the error, "Access to undefined property 'scaleMC'" on the removeEventListener line. My thought was to put another listener for mouse up inside the first, but that sounds wrong

fileReference.addEventListener(Event.COMPLETE, uploadCompleteHandler);
private function uploadCompleteHandler(event:Event):void {}
Above is one way to add an event listener in Actionscript. By default the callback function needs to have an argument with name event and type Event. Is there a way to declare this function without any arguments :
private function uploadCompleteHandler():void {}
Edit : It's possible to add an event handler without any arguments in mxml. So one student wanted to know, why isn't it possible to do the same in actionscript?

This is my first real programming endeavor and this is the last thing holding my little project back from being a success.
My goal with this code is to add event listeners to an array of Movie Clips that will drag and drop them on the stage.
Here is the code:
var itemBank:Array = new Array(d1_anim.drawer1.test01.movieClip_1, d1_anim.drawer1.test01.movieClip_2);
for(var i:int = 0; i < itemBank.length; i++) {

I am creating a map of the US. I've created a button for each state and named each button with it's 2 letter state code (AL, AK, AR, etc) in the library. I would like for each button to link to a directory on the site with a similar name, /site/map/AL, for example.
Rather than set up each button individually with script like:
on (release) {
getURL("/site/map/AL", "_parent");
}
Is there a way to consolidate the 50 buttons in to a few lines of code? If the destination directory were to change in the future I would then only have to change a couple of lines of code instead of 50 instances. I'm thinking the name of the button could be read and passed in to the button function, but I'm no programmer and not familiar enough with Actionscript to know where to start.

I'm working on a web app built in Flash AS3. At a high level - the app has a main screen, and several "modal dialog"-type screens that pop-up to manage various user interactions. (This is a similar pattern I use in most of the apps I develop...) Typically - when the user clicks a UI control on the dialog screen (e.g., button, text box, slider bar, etc.) - the main screen needs to react, or manage the consequences. It seems like there are two general ways to handle this: Have the dialog screen dispatch events that the main screen listens for Allow the dialog screen to call functions in the main screen when those controls are clicked (which requires that the dialog screen maintain a reference to the main screen, and that the functions in the main screen are public)
In general - I understand that one of the key benefits of the first method is that the dialog screen isn't so tightly coupled; it's only responsibility is to broadcast the event. This would allow me to more easily use the dialog class in other contexts, or applications. But for many RIAs I develop - a particular screen is SO SPECIFIC to the the application that there's no chance I'd ever reuse it in another application. So, the "easy re-use" benefit is minimal. So - if you eliminate that benefit - which method is actually better? (More performant, less resource-intensive?) For example - if I use events, then Flash needs to manage many listeners for events that may never occur. So - it might be more efficient if the dialog window could call a function in the main screen directly, instead of dispatching an event.

The line: Master process not found, or multiple masters
appears in /var/log/messages of a Centos server running FMS 3.5 right around the time Flash videos stop working on a site we built. Oddly, nothing appears in /opt/adobe/fms /logs/ master.xx.log at the corresponding time*. Is there likely to be any more illuminating information somewhere on the server, to help us identify what caused Flash to stop working?

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)

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.

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 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'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++) {

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 have multiple buttons with the following script applied which waits a second while a transition animation plays then loads a new image into the container... There seems to be a problem with having this code applied to multiple buttons unless I make the function and interval identifiers unique (i.e. transitiondelay1/waitFunction1,transitiondelay2/waitFunction2, etc.). I don't really want to have to do this to each button.[code]
