What is the correct way to refer to the dispatcher listeners in the following code so that I can remove them within completeListener()?
Code:
private function createLoader():void {
// Create the Loader
[code]....
I have this in my constructor:
[Code]..
The problem is I get Error: Error #2094: Event dispatch recursion overflow. Why does removechild keep getting called if this.parent does not exist? Why doesn't removing event listeners work?
If you have multiple event listeners running, is there any way to remove all of them at once rather than one at a time?
View 3 RepliesI have a basic question about manually removing event listeners in actionscript 3.If I have a function like:
private function doStuff(event : Event):void
{
//let them save
var f:FileReference = new FileReference();
[code]...
How do I remove the event listeners when the saveDone function is called? Normally I just change the "add" to "remove" like:
f.removeEventListener(Event.COMPLETE,saveDone);
However, f is a local variable, and I can't get to it after the doStuff function ends.
private function saveDone(ev:Event){
f.removeEventListener(Event.COMPLETE,saveDone);
}
I'm trying to do something that I'm not sure if it's possible. I have to add or remove multiple listeners that will trigger the same three methods (onComplete, onError and showProgress). I was trying to do something like this:
[Code]...
Is there anyway to solve this? It seems that after passing through the addListeners method, the loader instance gets lost.
I was just wondering--and it's probably an obvious question really--if I make an object null and that object had one or more event listeners registered, are the listeners removed?
for example:
Actionscript Code:
object.addEventListener(Event.SOME_EVENT,callBack);
function callBack(evt:Event):void
{
object = null;
[Code].....
In this case have I removed 'object''s listener when I made the object null?
ive made a flash website containing 5 pages all accessed via flash buttonson one of the page ive tried loading a external swf file and then added event listeners to each of the buttons so when a new page is selected the swf file doesnt continue to play in the background on the other pagesthis works, however when i then try to change page again this error is displayed:ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.at flash.display:isplayObjectContainer/removeChild()atValleyViewingWebsite_fla::MainTimeline/btnClick()below is the code im using:
var Xpos:Number = 110;
var Ypos:Number = 170;
var swf:MovieClip;

I'm creating a class for a game, and I'm having a problem removing event listeners from movieclips in that class.In the class file I have an enterFrame event which puts the movieclips into motion - I want to remove that event listener when the movieclip is removed from the stage.I made the function 'public' in the class file and tried to target it as follows (animal is the movieclip)animal.removeEventListener(Event.ENTER_FRAME, animal.onEnterFrameHandler)
View 2 Replies I have l modded some code that I am really happy with, it makes buttons bounce around for the user to try to click on when entering a certain frame.. I notice tha the code adds eventlisteners ENTER_FRAME to make this work, when you leave that frame there are now problems with null objects becuase the listeners are still on but the objects are not there anymore..
Ok so attempted solution - I can use a currentLabel on the main timeline to check if the correct frame is reached then use a function if (label is x) put listeners on else take them off... works but then I have to have these objects hidden on the timeline and then add visible=true/false to my framelabel listener.. This works but part of my functionality here is that these movieclips that move are buttons that the user clicks on and they explode and dissapear- but now they dont because I have a code that says on that frame they should be visible..
The only thing I can think of is to have a blank frame at the end of the explode and put a stop on it. Then add a gotoAndPlay(1) into my frame label code. Seems very ugly, you guys got a better way? Can I remove eventlisteners on leaving a frame? Is there a code like LEAVE_FRAME??
Do you have to remove event listeners on variables with local scope? By this I mean...does the event listener still exist if the variable only exists as long as the function/method is running?
private function startSomething():void
{
whatever.start();

I'm adding and removing stage event listeners I am relatively new to AS 3 and have been building a liquid layout site unfortunately I do not have a strong grasp of classes and have been doing all of my scripting on the main timeline with encapsulated script within MC's.
basically I am calling on the same functions over and over and those are mostly resize functions which I have added StageEventListeners on the appropriate frames to listen for resize events on that stage now as of now I have literally dozens of these scattered about the site. when testing my site things are running fairly smoothly however I keep getting error messages in my output window that go a little something like this.

I'm trying to develop a catching game, just for a bit of fun and learning experience. I've been bouncing between tutorials and I've finally come to a point where I can't get any further. After you catch three sandwhiches, you lose and it takes you to an end screen, however, I'm unable to stop the listeners from being called, and when the game restarts, the food falls, but you're no longer able to catch it or keep score.

I've created a drop down list and populated it with dynamic buttons. (I made a DropDown_btn class with a dynamic text field in it and then filled the button text from an xml file). On rollover I tint the button blue and then set the tint back to black on rollout. When you click on the button I'd like it to stay blue until a different button is clicked.
I thought on CLICK I'd run a function like this:
ActionScript Code:
function removeRollover(evt:MouseEvent):void {
evt.target.transform.colorTransform=c;
evt.target.removeEventListener(MouseEvent.ROLL_OUT, btnOut);
evt.target.removeEventListener(MouseEvent.ROLL_OVER, btnOver);
}
...and then I need to addEventListeners back to any button that doesn't have them and set that button back to black. I could do this by looping through an array of the buttons but I can't figure out how to access them as objects.
I also gave them each a property of "buttonValue" when I loaded them so I can access event.currentTarget.buttonValue (which in this case is a number from 1-5) but once again I can't figure out how I might leverage this information.
i made a SWF which contains a loader which loads any SWF file passed to it... the problem I'm encountering is that for some SWFs, some event listeners doesn't fire anymore... my own SWF file (which contains the loader) doesn't really have any other element except for the Loader object and so I cannot understand what seems to be preventing the loaded SWF (loaded by my Loader) from receiving some mouse events
it seems that the for the SWF where I'm having this problem, the listener seems to be tied up to a location in the stage or somewhere else, and so whenever I resize, the listeners is not responding on the right place, for example, the button appears on a certain position but the listener's hit test or whatever the SWF is using to detect the mouse click is positioned somewhere else
I want to make a static function that I can use in all the custom classes.It should be some kill(); function that would remove the object from the stage as well as removing its event listeners. I made it in Document class, and it didn't work. Here's the code:
ActionScript Code:
public static function kill(e:DisplayObject)

I know using the UI loader when I needed to remove from the stage I used
MovieClip(loaderVideoGallery.content).flvPlayer.stop()
this time I need to remove a loader class event loader from the stage[URL]... The scenerio is I have 5 externally loaded .swfs that load on different frames on the timeline. When one is playing and another button event listener is clicked the previous video remains on stage. This happens when I go anywhere else in the timeline so I would think I need (removeChild)
Wouldn't this have to go in every button listener? If I went from a frame that loads an swf to the the frame that displays the homepage where text is in the place of where the swf was I would need to always have the remove Child event in all other button event listeners am I correct?
I need to have scrub thumbs for video player load and unload repeatedly.
Something isn't getting cleared. Every time the thumbs are removed, there's a slight increase in the cpu baseline - something is piling up in memory.
Below is the relevant code:
Code:
function showScrubThumbs():void {
xmlLoader.addEventListener(Event.COMPLETE, xmlLoaded);
xmlLoader.load(new URLRequest("testThumbs.xml"));
}

I'm moving two objects accross the stage at different rates using the same function:
Code:
function moveClip(clip,speed){
clip.addEventListener(Event.ENTER_FRAME,moveIt);
function moveIt(event:Event) {

In AS2 I'd just use dot notation as above and it would work from anywhere or perhaps _root.red....
I've tried root. stage. childbyname Not sure where to from here.
I am trying to have a single parent class that a wide variety of classes can extend. Each of them has the exact same event listeners and remove function so I thought I would try to write the function a single time in the parent class.Parent Class:
Code:
public function removeMe():void {
/* REMOVE EVENT LISTENERS */
[code].....
almost every single one of my classes, starts with the same method. An event listener in the constructor for EVENT_ADDED_TO_STAGE. Then i do all my actual intialising in a beginclass function that listener runs.I've not generally been removing these listeners though. i never thought it would make a difference since i'm only adding these objects once, but i wonder if there's a performance element. it could be for example, that all of these listeners add an extra check each, ehenever any object is added to the display list.
View 1 RepliesCan event listeners only be added to the class which dispatched the event? I ask because I want to have the logic for the listener on the main class, and the action is dispatched on click from a thumb which is instantiated in a scroller class. Kinda like this:
ActionScript Code:
pseudo code:
class main {
main() {
[code]....
This doesn't work. Why can't the main class listen for an event on the thumb class?
The title describes the problem: Loader.load() is firing the INIT event, but in my listener it's reporting loader.content as null. The description for INIT event is "Dispatched by the associated LoaderInfo object when the properties and methods of the loaded SWF file are accessible."I'm loading a lot of JPG images, and 95 percent of the time it works fine; the init listener fires and reports valid loader. content.I absolutely need loader.content available because I need to set the bitmap smoothing property to true.I've tried using Event.COMPLETE and it has the exact same problematic behavior.
View 13 RepliesAn odd thing is happening for me, my eventlisteners only fire off once then they seem to stop working.
This thing is a movieclip that slides up the parent movieclip and another movieclip within mc slides it down. They only work once.
ActionScript Code:
slider.up.addEventListener(MouseEvent.MOUSE_UP, activateSlider);
slider.down.addEventListener(MouseEvent.MOUSE_DOWN, activateSlider2);
var frameBoolean:Boolean = false;

I got this very strange behavior from FlashPlayer debugger 10.1 r82. When I call loader.load method, no ADDED event is dispatched to the loader object. But if I open the file and call loader.loadBytes instead, an ADDED event is dispatched to the loader object. I suspect the ADDED event is dispatched because the content is being set as the child of Loader object, but why in the other case it is not dispatched?

I am designing a site and one problem has been persisting for quite some time. I want to remove an swf once a second page has been added here is the website design > a preloader loads my main menu, on the main timeline of my preloader.swf I create a new loader(loader1)
and tell it load the URLRequest "menu.swf" > The menu.swf loads, on menu.swf main timeline I create a click function (instantiates once a button has been clicked) that loads my second loader (loader2) and this loads the URLRequest "cast.swf"
I want cast.swf to replace menu.swf and remove it entirely but I cant figure out how to do it, here is what I have tried inside the click function of menu.swf (is this possible? can you write code to remove an swf if you are actually inside that swf's main timeline?) removeChildAt(0); (this only removes the bottom layer of the menu.swf) removeChild(MovieClip(root).loader1); inside the click function (this does not remove the menu.swf)
I have 5 GoToframe activated UI loaders that appear on stage when a btn is clicked. All work fine except when either video galleries are clicked (there are two) . After the video gallery appears on stage any button clicked after that adds the next UI loader but the video gallery remains playing.
Do I use a removeEventListener?
Do I use on all buttons?
Create separate functions?
here is the code to one of the galleries
this.stop();
btnGallImg.addEventListener(MouseEvent.CLICK, vgall2);
function vgall2(evt:Event):void {
gotoAndStop("gallery2");
}
I have a flash file that counts and displays the number of images in a particular folder, that part appears to work fine. I require a reset button so that the alternate directory for the images can be tested as well. For this I need to delete all the instances of the loader I created for each image, but am unable to do so.
ActionScript Code:
import flash.display.Loader;
import flash.net.URLRequest;
import flash.events.IOErrorEvent;

I have 4 separate photogalleries, they are all swfs called by buttons with UI loaders attached. The problem is when one is called the loader remains on the stage I need to be able to remove any loader on stage BEFORE calling another page weather its a photogallery or not.Easiest explanation is how I used to do it in AS2 example 2 btns /2 load separate swfs into level1 on each btn I would have
unLoadMovie(1)
LoadMovie (xxx.swf) 1
I need to do the same thing in AS3 Also, do I need to use separate loaders or can I use one loader and instance names? Below is the code I have now (btns are in two areas)
main timeline btns (all btns except photogallaries)
stop();
home_btn.addEventListener(MouseEvent.CLICK, onHomeClick);
[code]....
