Is there anyway through which we can know that which event listeners are currently active and we can remove them at runtime? I am trying to create drawing board which have different shapes to draw. But I have to add event listener with for every shape and have to remove previous listeners. I want to remove the all active listeners in one go. Is it possible.??

I did some research and it seems quite an issue - especially when trying to remove, enterFrame, mouseMove or stage listeners. Im using CS3.
First shortly about how my site works: When a link is clicked it checks if something is already displayed in either the Left or Right side of the screen (the website looks like a book, so I have a left page I want to display information on and a right page). If there is already something showing it hides it and displays the new object, together with this it enables all the buttons within that object (I have separate functions to set up each object).
An example of such an EventListener would be:
pathTo.Button1.addEventListener(MouseEvent.CLICK, function():void {showText(side, object)});
What I'm trying to do is to remove all the previous set EventListeners without having to create separate functions for removing the links inside every object as well.
How do I remove all EventListeners on all objects inside another object? The only variable I want to store is the object containing everything. There are however not always EventListeners within the objects.
I have 20 buttons on my stage, and rather then have 'removeEventListener' for each button, i wanted to use a loop to do so. Heres what i have done.
Code:
//array containing the buttons instance names.
var soundArray:Array = new Array();

I am trying to improve the performance of a mobile application and I am trying to trouble shot what part of my code/application is causing a performance problem on some mobile/tablet devices. The application has several frames, with anywhere from 3 to 15 event listeners in a frame. At first I was not removing an event listeners. Now I am removing the event listeners as the user leaves the page.[code]I was wondering could removing too many event listeners cause performance issues? Also, is there a an easier, more efficient way to remove event listeners?

View 6 RepliesI'm trying to remove movieclips created at run time using "createEmptyMovieClip" but I'm having a problem calling the "removeMovieClip" function. The difficulty seems to be that the string that I assign as the instance name of the new movie clip doesn't actually refer to the created clip when I try to call"removeMovieClip".
So the "removeMovieClip" function doesn't work if the target name is pulled from the array. My guess is that this has something to do with the values of the array being strings...and it does when I manually type Apple.removeMovieClip(); in because Apple is the movieclip object name. How do call the "removeMovieClip"function using a var as the target?
After adding an image to the stage, turning it into a Movie clip, and setting linkage in library to Export for Actionscript, I'm now using a timer to add a bunch of roses to the stage as a video plays.How can I get rid of all these clips once the video is over?Do I need to add all of them into an extra container and then just removeChild that container at the end? Or do I need to use something like getNumberOfChildren and then create a loop that removes them one by one?The clips (myRose) are fairly small and do not have any event listeners added to them. I just use TweenMax to move them from top to bottom of the screen.

I have a window component on my main timeline that gets called up on several instances. When the popup window appears, everything looks fine, except that the user can still click on links that are now behind the actual popup window itself. My question is how do I keep those buttons from being active while the popup window is active?
View 2 RepliesI've seen the Loom project, but are there any alternatives that are more mature (and actively developed)? I am looking for something that would allow load-time weaving of pointcuts into existing binary code at runtime with the AVM2 runtime.

I've been into coding for about 5 years now, but I'm a recent convert to Flash development. One of the questions I have at the moment is, considering that SWF files can be run by either Adobe Flash Player OR Adobe AIR, what's the real difference between the two runtime environments? What API's and Objects exist in one environment, but not the other?
Basically what I'm more or less trying to establish is, when would I want to develop an SWF for AIR, and when would I want to develop for Flash Player, considering that Flash Player can also execute locally (providing support for creating "desktop applications")
Whenever I link a set of movieclips together with the bone tool which are inside a containing movieclip, and also set the type to "runtime" instead of "authortime", I get this error when published.
"Runtime symbols with skewed matrices should be wrapped in a movie clip" What does it mean? I need the type to be set to runtime so I can use scripting with it..
Let's say I have a global SoundChannel object, and inside a function I am repeatedly creating new instances of the Sound object to play songs one after the other. Each time I do this, I need to add a new eventListener to the SoundChannel to call the function 'onSoundComplete' that will load the next song on completion.Coming from a strict C++ programming background, I often wonder if it's necessary to do some kind of cleanup in Flash, or if it handles it automagically.Here's example code that specifically removes the eventListener from the previous Sound object everytime a new one is created, but I don't want to be doing this if it isn't necessary:
Code:
// Setup sound object buffer
var slc:SoundLoaderContext = new SoundLoaderContext(3000);

Inside a .fla file I have some buttons and each button will tween a different image to the stage. All the images are outside the stage in the same x and y position and I just need to tween the x coordinate.
Now I'm working with an external document class where I'm trying to hold all my functions and I'm stucked with the Tweens. I'm willing to stay away from the flash tween engine and I'm trying to work with tweenLite.
Is it possible to pass parameters through eventListeners so I can use something like this inside my docClass?
public function animeThis (e:MouseEvent, mc:MovieClip, ep:int):void { //ep stands for endPoint.
TweenLite.to(mc, 2, {x:ep});
}
If this is possible, how am I supposed to write the listeners so it will pass the event to be listened for AND those parameters? And how to build the function so it will receive those parameters and the event?

I keep getting an "1120:Access of undefined property buttonOver" error. I know it's because the EventListener is outside of the function "navigation" but I need it to be accessed by other functions later.

I tried using a .enabled = false; when I already had a click event on that movie clip. I found that you need to remove the eventlistener instead of making enabled false.Why doesn't enabled work when you have event listeners?I'm really more curious than in need of an answer since removeEventListener worked fine.

I have a menu with buttons on the stage that when clicked load external swf but the problem, although i can remove them from the stage, is that they are still playing which gives my site performance problems. I gave weak references to the Event Listeners but i didn�t remove them.Here�s the code:
Code:
import flash.net.URLRequest;
import flash.display.Loader;
import flash.events.Event;

How can i remove each the listeners from each swf so that the site doesn�t perform so slow?
Say I have this code:
Code:stage.addEventListener(KeyboardEvent.KEY_UP, reloader);
function reloader(e:KeyboardEvent):void {[code].....
and this:
Code: var reloadT:Timer = new Timer(2000, 2);
reloadT.addEventListener(TimerEvent.TIMER, on_timer);
reloadT.start();[code].........
So I have a code that tracks Key_UP and one for a timer. However, I want to somehow use them together, like inside each other: ex. Run the timer function in Key_UP.I want to trigger the timer only if Key_UP is found. How would I do this?
I got a pickle for you: I have a function that is currently connected to an event listener like this:
Code:
loginButton.addEventListener(MouseEvent.CLICK, loginOnClick, false, 0, true);
function loginOnClick(event:MouseEvent):void{
// Login code.
}
Right now I'd also like to call that same function using the ENTER from a keyboard since loginOnClick doesn't use the parameter received (event:MouseEvent). So I did this:
Code:
function keyboardListener(event:KeyboardEvent):void{
if (loginButton){
if (event.keyCode == Keyboard.ENTER && loginButton.enabled) {
loginOnClick(); // Generates an error because it doesn't have a parameter.
}
}
usernameTextField.addEventListener(KeyboardEvent.KEY_DOWN,keyboardListener);
Problem is, of course, AS3 doesn't let you call a function with the incorrect number of parameters or types. I tried following senocula's tutorials on functions and parameters but they don't seem to work on this very specific issue considering the parameter is an event reference.
I am creating a small image gallery and I am creating the actual images dynamically. The images are stored via json and I am listing them underneath each other. No I can get all to work and they all load and position each other correctly underneath. What I would like to do is assign each image a addEventListener so that when clicked they pass the necessary details onto another function which will then display a larger image simple and basic but I am having trouble with adding the eventlistener. each one gets an eventlistener to it but when clicking on each one they all show the details from the last one. The code is attached to the main gallery container is as follows:

I want to know if there's a 'correct method' in removing a MovieClip off the stage. I am currently programming in simple OOP and I have 2 classes, for now lets relate them to Tree and Fruit. The fruit is the child of the tree.
When the fruit is being clicked on. the tree AND the fruit will fade off and I will perform a removechild only on the tree. So I'm now puzzled if just removing the tree would automatically remove everything including the fruit(without performing a proper tree.removeChild(fruit)) and all the eventlisteners attached to fruit?
If not, must I perform remove child on every single MC/Sprite I have added onto tree/fruit for the best performance? Would like to find out how you go about doing it the 'correct way'.
