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].....
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) {
[Code]....
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.
Im attempting to create a class which cleans all the mess it's done by itself. If i make some instances of this class in an external class, i want the base class remove itself, or in other words, if i linkage this class to any movieclip, i want to remove this movieclip not in the file I created it in, but rather would like it to automatically remove itself if i want it to. I don't know if it's even possible. A simple removeChild(this) isnt working.
View 3 RepliesI have created 2 sprites each containing a dynamic text field child. I then add this as a child of the stage. (I have done this in order to make the text clickable with a hand cursor on mouseover)It loads in fine, I just run into problems when trying to REMOVE it the sprite containing the text."ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller."Sections concerned in red:

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 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 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;

What is the correct way to refer to the dispatcher listeners in the following code so that I can remove them within completeListener()?

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.
[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 RepliesI'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 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:

public static function kill(e:DisplayObject)

Say my flash project has an object A. In object A is an event and it's corresponding listener B. How do I get listener and event B to function in my flash project? I remember it something to do about "focus", right? Or am I completely off target, ha?

However, either I'm declaring my variables at the wrong bit/way or there is another problem, as I have been able to add the child I want to from the display list (sidepoint: is it right to call the display list everything in the library on stage at runtime plus those things you have exported for actionscript usage??!)...but when I want to remove it at the next cuepoint nothing happens. I feel this is a basic principle that is alluding me here.

vid.addEventListener(MetadataEvent.CUE_POINT, cueText);

Im using the following code to create a mc from a template iv made stored in the library:
var galleryThumbs:MovieClip = new contentTemplate();
galleryThumbs.x = 710;
galleryThumbs.name = "galleryThumbs";[code].........
that all works fine but then im trying to remove it with this, with no success:
if (galleryBox){
removeChild(galleryThumbs);

Here it is:
var ZombieInstanceTimerL:Timer = new Timer(8000,60);
ZombieInstanceTimerL.addEventListener(TimerEvent.TIMER, ZombieTimerLfunction);
ZombieInstanceTimerL.start();

Basicly im first setting a timer of 8 seconds for a zombie to sprawn then it sets the properties and then using the addChild method it adds the zombie every 8 seconds. then i made the zombie move but as if it hits the character i make it stop and go to the attacking scene which is frame 4 and then when it isnt hitting it, it goes back to frame 2 which is walking,, then i made a Zombie death code which works by in the zombie attack class it has hittests for all the weapons and it reduces a varible in a GlobalVaribles class the varible is called ZombieHP and here it says if ZombieHP is below 1 it should go to 3 which is the death scene and add a point to the score but the hp and gotoAndStop affects all of the zombies so when it hits one they all die how can i make it so only the one its hitting can be affected..
I'm trying to remove an instance by name, that was previously captured when it was created. (in a property)
ActionScript Code:
trace(this._blockInstance); //returns instance name, eg "instance203"

ActionScript Code:
this.removeChild(getChildByName(this._blockInstance));
error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.

I've run into a problem when trying to move one of my sprites from the stage when it dies.So far what I'm having to do is call the Death method from the main class, which then goes to the Enemy Class in order to play the animation, once the animation has reached the last frame an event is triggered which is situated in the main frame which then removes the now dead enemy from the stage. However it doesn't appear to be able to target the child which I want removed =/Main Class:

private function hitCheck(e:Event = null):void{

Have a rather bizarre issue with Flex throwing an error when teh application is running in the background. I use Selenium and SeleniumFlexApi to run various tests against my app. If the browser window is in the foreground or any part of it is visible to teh screen, the test pass as expected. However, if the window is in the background and not visible, I am getting the following error in 1 part of my app.
ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller. I have a VBOX that creates a number of children and then upon creationComplete(or UpdateComplete, I've tried both) it then needs to remove any of the children that are not visible. Each child has a listener for CreationComplete which checks if the child is visible and if not, adds it to an array which is iterated over when the parent UpdateComplete is fired. I cant seem to find any reason for this behavior and am curious if its an issue with the Flex Component LifeCycle.
In my document class I have assigned the root of fla to theRoot movieclip as theRoot = MovieClip(this.root); And as my program proceeds I have added several childs to theRoot. Now at the end of my program I need to delete all the childs of theRoot. So,how can I do this without individually deleting single childs.
