I am sorry if this is a truly basic question, but how would I code as3 to remove an event listener when the current frame (in my case, section of my site) is no longer on the stage?ke the following code as an example:
function onClick(event:MouseEvent):void
{
doSomething();

if i have a movie clip with an even listener attached to it, is the event listener being removed automatically when the movie clip is removed from the stage or should i always remove the event listeners manually?
View 4 RepliesWhen bullets hit the wall of multi-colored blocks, when shot one by one, they disappear like they should. But if you hold down the Left Mouse Button, you will see that bullets stop in mid-travel and I can't figure out how to fix that.
See this occur in this SWF. Note:(Use A & D to move left to right, Z to add a new row, and Left Click to shoot)
Here's the important function in the Bullet class.
Code:
public function update():void {

I've noticed that using stage.addChild(obj)(i.e. creating objects on the fly) can slow down frame rates.I was told by several sources that one way to speed up a flash game engine (or any animation where instances are generated as you progress), is to reuse objects in what is known as object pooling.
First of all a bit of background:The game engine I'm working on can be found at: http:[url]....Most objects (i.e. bullets, particles, enemies...) are exported for actionscript, each with a set of actions that are performed each frame, and another set of actions upon being created.Each class has an array called instanceList, which keeps track of all objects currently within play.The main timeline contains an event.ENTER_FRAME function mainActions(event:Event):void, that loops through each of the instances and performs the actions associated wit11h each.It goes through each instance of each class by going through the static array instanceList().
Now what I plan to do is:Have a seperate static array for each class, called inactiveInstances,which keeps track of deleted objects.Introduce a function for adding the objects back to the stage (with the nesscessary variables reset), to give the impression of a new object being created.When objects are destroyed:Should they be removed from the stage and readded latter e.g. removeChild(obj2)/addChild(obj1)? e.g.
Code:
public function instance_destroy()
{
parent.removeChild(this)
//Remove all refferences and listeners[code].....
The REMOVED_FROM_STAGE event is fired before the object is actually removed from the stage. I'm looking for a performant way to know when the object is finally removed.

In the past, using Flash CS3 when I needed to remove timers or event listeners from a swf that had been loaded into a parent swf I'd use this inside the loaded swf:
Code:
this.addEventListener(Event.REMOVED_FROM_STAGE, deactivate, false, 0, true);
function deactivate(e:Event):void
{
[code]....
Now that I've upgraded to CS5 and am outputting to Flash Player 10 this no longer seems to work. The event fires right away. Does anyone know why this might be and if there's an alternative that I can use?I tried the unloadAndStop() method in the parent swf but I'm trying to remove some TweenMax delay timers and it doesn't seem to be working.

I have a main swf that I load external swfs onto the stage. I am trying to fix the loading order. Currently when a button is pressed, the swf is preloaded, the current swf is on the stage with the preloader showing, then the preloader disappears and the swf plays the outro transition.
how to change the order so that currently loaded swf is removed from the stage, show the preloader and then show the new swf.
Code:
package
{
import flash.display.MovieClip;
import flash.display.SimpleButton;

I have two FLV files playing on the stage. The main FLV is instance is: MyVideothe 2nd is MyVideo2I have imported the videos using the wizard. The 2nd video is just a movie I created in Affter Effects that says...loading please wait....this is a really nice video and I don't want it to just use a standard preloader. Anyway, the goal is when the playback for "MyVideo" begins I would like "Myvideo2" to = visible = false;I have tried this many different ways and have been unsuccessful. I am obviously a newb at this. Also, does anyone know where I can get a list of all available eventListener actions...etc?
//var nc:NetConnection = new NetConnection();
//connection_nc.connect();
//var stream_ns:NetStream = new NetStream(connection_nc);

I have ran into another problem, I have written the code for when I click on an enemy, it doesnt add a point to the score and it doesn't remove the enemy, I have a textfield which is called messageDisplay which is linked to the clickEnemy function.Here is the piece of code.
stage.addEventListener(MouseEvent.CLICK, clickEnemy); function clickEnemy(event:MouseEvent):void { if(cursor.hitTestObject(enemyAppear)) { score++ messageDisplay.text = String(score); enemyAppear.parent.removeChild(enemyAppear); } } stage.removeEventListener(MouseEvent.CLICK, clickEnemy);
I am working in on a Flex / Air application (using PureMVC) written virtually entirely in ActionScript 3 (i.e. we use very little of Flex). View components are added to a Canvas object in the main application window and these Views then load other movie clips, images files, etc.When I remove a View from the stage, I do so using application.canvas.removeChild(). This fires an event in my PureMVC mediator for that View, which removes any event listeners that were set up and everything appears to be dandy.However, the movie clips are still playing in the background. They are not causing any trouble on screen but they are simply there, playing somewhere in memory (e.g. I can see trace statements from them) and I want them gone. I suspect the View that was removed from the Canvas is still there too, but I can't prove it.
Setting the View to null doesn't do anything. I'm surprised that AS3 doesn't include any method to simply and effectively destroy a Display Object and all of its children.Is the only way to do this to tediously unload all of the movie clips, etc. and then hope that Flash will clean them up?
I was told that if you load a new SWF into a loader that has an existing SWF that the second SWF will replace the object(the first SWF) in the loader and in the display list.Does this mean that the first SWF is removed from the stage once the second SWF is loaded? I am asking because I would like to know if my this.addEventListener(Event.REMOVED_FROM_STAGE, removedFromStageHandler1); in the first SWF will fire once the second SWF is loaded.

I have a website [URL] when I go there if I click the video archives button then play a video then click on the home or photos button or one of the alternate background buttons on the left the video goes away as it should but not always the audio (especially when I click while the video is still buffering). Is there a command I can use to kill the sound from the flvPlayback component and nothing else(I have a mp3 player there also I so I don't want to use the SoundMatrix class. btw the videos are all played on an instance of the flvPlayback component.
View 7 RepliesI have made the flash file into CS3 and simplified the idea a bit. Basically I want to click the box on the right to start playing the song and the spectrum and then if I click it again it will stop playing the song and the spectrum then if I click it again it will start playing again ect ect. I could not upload the song.mp3 cause the file size was too big you will have to replace it with another mp3 in the root of the folder and name the mp3 song.mp3.

I'm having issues removing event listeners once they're added in cs4 jsfl. I tested the same code on cs3 and it removes the listener just fine without errors. In CS4 if I try:fl.removeEventListener("mouseMove", movieclipListener);I get the error:removeEventListener: Argument number 2 is invalid. If I try:fl.removeEventListener("mouseMove");I get the error:Wrong number of arguments passed to function "removeEventListener".
So I'm summarizing that: - the removeEventListener has changed between versions cs3 and cs4- Neither method works in removing my event listener Tried running this in the same script that added the event listener (same script that contains the function called), tried running in a separate script. Same errors.

2. After removing the event listener, I still get output from hasEventListener
So, how does this really work?
3. Event listeners like Event.COMPLETE are events that happen once, then not again. One would think these kind of events also would delete its event listeners. Is this so?
It is very ridiculous that I can't remove a simple listenermethod :). I think this is a common problemWhen I am using removeEventListener manually, i.e outside thecondition its working fine, but whenever I am using it inside theif/else condition it is adding the listener in "true" mode but notremoving in the "false" mode.here is my code:
if (proAlign == true) {
trace("align Option = " + proAlign + " -- " + "this is true
part");

I need to disable an onClick action until an animation has stopped. Animations can be started by 4 different buttons - all need to be deactivated.I use a listener to pass params to the function that will initiate the animation which is why I use an anonymous function in the add listener:

function(event:MouseEvent):void
{ [code]............
How to call removeEventListener when I don't know the function which is the event handler?
