ActionScript 3.0 :: How To Remove Dynamic Objects
Nov 25, 2009
So far I have this squid-shaped MC floating and making bubble-shaped MCs which rise to the top of the stage. The bubbles get generated by following the squid's (x,y) cordinates. The whole thing looks convincing enough. The only problem is that as the memory gets full, the bubble animation degenerates, so I want to remove them once they reach the top. I figured I could use a removeChild() function tied to the same EventListner that makes them rise, but once removed it will look for the object again and throw an error. I know I'm missing something simple here, but I can't pin it down.!
Code:
var bubbleTimer:Timer=new Timer(1200);
var i:uint = 0;

picture: [URL].. I am making a boardgame in flash Action Script 3 each position on the board is a buttons like this: button_1_1, button_1_2 etc. Whenever a character is selected you want to move it so the script has to add event listeners for positions around the selected unit
[Code]...
In the rest of the code I have:
function userClickedPosition(position_x:int, position_y:int) it selects or deselect a unit function selectUnit(position_x:int, position_y:int):it uses the listentoButton(1) function to add 8 listeners (the positions around the clicked unit)function deselectUnit(position_x:int, position_y:int): it uses the listentoButton(0) function to delete 8 listeners (the positions around the clicked unit)
My question: adding eventlisteners is no problem but removing them dont seem to work? What did I do wrong?

I have some objects on a form with the following instance names:
item_box1
item_box2
The following code will NOT remove all objects with "item" as the first part of their name. Why and how can I fix it?
ActionScript Code:
for(var i:int=0;i<main.numChildren;i++) {
if(main.getChildAt(i).name.substr(0,4) == "item")

I once saw an effect on a flash add I wanted to try make myself also - the cursor makes a vake that blur out and disapear, much like the vake of a plane, just faster. The problem is I need to remove the vake when it has faded out, or else it just stay in the background and fill up forever! I know there must be an easy way for this. Can some of you tell me the best way here? I have attached the fla-file and scripts. You see a comment where I try to put the code...

I am making a flash game. The game starts off running fast and smooth, however 15 minutes into the game it's noticibly slower. I worry that I am causing memory leaks by not removing objects from my game properly. I understand the whole garbage collection idea, but I still need confirmation.

Now, In my stage it works nice but when I see my Computer Memory status. my current flash.exe is increasing memory rapidly. Is how to remove my unusual object from my Memory. So that it would not get hang.

I'm trying to remove all objects from an array, and then emptying the array using splice. I'm restarting the game, removing all objects etc so that I can add them again. But what happens is that no object (enemies, blocks, bullets etc) is really removed. It's not visible anymore, but it's still on the stage wreaking havoc (hit detection still working, so enemies are avoiding enemies that were supposed to be removed, bullets hitting them and so on). And then when I restart the game a couple of times I have way too many objects and the game starts to lag. Code below: This is the code for the enemy, I have different loops for the other objects, but they all look the same:
Code:
for(var a=0; a<enemy1.length; a++) //loop through enemy1 {
if(enemy1[a].dead == true) //check if dead {
removeChild(enemy1[a]); //remove from stage
enemy1.splice(a,1); //remove element from array
}}
So to reiterate, I need to remove the objects from the stage, and clear/empty the array.

I have an array containing objects, where each object contains a boolean. I was wondering how I can remove only the objects where the boolean is set to true.I've tried doing it like this:
for(var k:int = 0; k < ballContainer.length; k++){
if(ballContainer[k].isCheck == true){
removeChild(ballContainer[k]);[code]....
But it doesn't seem to work that well. (Reason for it not working may very well be another reason, but I thought I'd check here anyway since I'm an AS3 novice)

I am using a carousel (from Lee Brimelowe's tutorial) as the main method of navigation from my site's homepage. There are six icons in the carousel, clicking any one brings the icon to the front and some dynamic text and a button to navigate to a different page appear on stage. Clicking the icon again brings the icon back to the carousel and the text and button disappear.The site is multi-lingual (English, German, Dutch, Polish) and all text changes to the relevant language by clicking a flag button, including the text that appears beside the 'expanded' carousel icon - all of the data is loaded from XML files.
The problem with changing the language is that the entire carousel needs to be destroyed and rebuilt each time, as all of the data needed for it is only loaded on runtime. I have this 'kinda' working, the problem I am having is:If you change the language via a flag button when an icon is 'expanded' the dynamic text and button (theText and urlBtn) get 'stuck' on the stage and you have to do some clicking on the new carousel icons remove them - not ideal!Can anybody out there please advise me on how I would include some AS to remove these items too when the language button is changed?

This doesn't work at all.[code]...
but adding "removeDuplicates(aPeople);" after "createfile(thename);" has no effect: in other words, when I push the savefile button, it keeps creating clones of the same objects. What can I do?

I am creating a generic button that will remove items created dynamically in a movie clip container from memory (not just from the display list).
To track which item the user has selected for deletion, I have a click function that stores the name of the clicked object in a variable called objName. I then store a reference to the object itself in another variable called targetObj. I can then easily remove the object from the stage like this[code]...

know how to remove objects like Plane from Papervision 3D scene? I have tried container.scene.removeChild(plane); but it gives me an error like this:"1119: Access of possibly undefined property scene through a reference with static type flash.display:Sprite." So what I'm understanding is that I can only use removeChild() with Sprite objects (and maybe MovieClips) but I cant remove objects that are part of Papervision scene?

How on earth do I use the onMouseDown event to remove objects generated by an array?
I'm still programming (if my bumbling can be called that ) the game I discussed in the 'Random Object Generation' thread and I'm using the basic framework of the array function that h88 gave me. Everything is working fabulously, but getting the things to disappear onMouseDown is a problem - it doesn't work.
Oh, and if I reference Target.prototype.onMouseDown and tell it it to this.unloadMovie, it unloads every single target on the screen instead of the one your mouse is actually over, making for a fairly... lame... game. I'm pretty sure it's because every single clip generated by the array is a Target prototype instance and so when the MouseDown occurrs, it unloads every Target movieClip. And I am using a hitTest in the Target.prototype.onMouseDown command, so that doesn't solve anything...

I'm creating a simulation in which a large number of objects are added to vectors and then taken away in random order (as more are being added). To remove the objects, I splice the object from the vector it's in, and notify all the other objects that an object ahead of them was removed so they can change their indices accordingly. As far as I know, the objects have no other references (I think), and within the object, I set everything to null. I read somewhere that you can't put "delete this" in the class, so I didn't bother with that. Will this be sufficient to get the object garbage collected, or should I do something else? What are the best ways to get something like this garbage collected?

Is there a way to generically remove an object from an array? (maybe not using array.filter or creating a new array)
Example:

var someObject:SomeClassObject = new SomeClassObject();

I am adding a Timer object when my flv playback enters a Pause state and removing that Timer Object when playback starts again. I noticed that if I pause the movie and then drag the slider on the timeline the movie enters the Pause State again which adds another Timer Object....
How do I check to see if the Timer has already been added and if so remove it and add a new one.
See code below:
my_player.addEventListener(VideoEvent.PAUSED_STATE_ENTERED, pausePlay);
my_player.addEventListener(VideoEvent.PLAYING_STATE_ENTERED, startPlay);
function pausePlay(e:VideoEvent):void {

Why and when? Because I addChild to the stage 1000 times but only removeChild 800 times, and even so, stage.numChildren returns to 0 after all my objects have exceeded the stage boundary. I have to mention that I am moving objects from left to right (it's a game) and the object's X and Y properties eventually exceed the stage boundaries. Does something happen automatically then??? Like... events removed or something like that? This is a continuation of this thread of mine, where I initially thought addChildren has issues: [URL].

I'd like to remove objects via removeChild after Tweenlite has finished tweening. But it doesn't really work because my objects are still in the DisplayList.
Code:
//TweenLite.to(sndText, .5, {alpha:0, onComplete:removeChild, onCompleteParams:[sndText]});//does not really work; still in DisplayList
TweenLite.to(sndText, .5, {alpha:0});
TweenLite.to(musicText, .5, {alpha:0});
TweenLite.to(sndSlider, .5, {alpha:0});

ive come across this method 'as' and I dont get it.I am following a tut, and i have an array with my objects stored in it(for reference to control these sprites).They are instantiations of my sprite class 'Ball.as'
Code:
for(i=0;i<3;i++){
var myMCs:Ball = myMCs[i] as Ball;
}
when I remove it - flash doesnt seem to mind its absence.

I've created an XML thumbnail gallery, and would dearly love to add a simple looping preloader animation to each of the thumbnails whilst they are still loading. I'm struggling to remove the preloader movieclip, once the corresponding image has been loaded.
I'm currently creating the new movieclips within the loop, so I'm having problems referencing them in the following load complete function. I gave naming the "spin_loader" instances a go (i.e. spin_loader.name = "spin" + i), and then trying to remove it in the "thumbLoaded" function ( i.e. project_mc.removeChild(getChildByName("spin" + spinNum)), where spinNum is the equivalent number to "i"), but I just can't seem to crack it.
Code:
function createThumbs()
{
for (var i:Number = 0; i<my_total_project; i++)

I have a for-loop that creates instances / duplicates of a movie clip that works like a charm:
[Code]...
Then I position each instance- and I fill an array with the number ("pg"), because: I also have the option to switch to a different view and at that point I want / need the MoveClips to disappear. So I have a function tied to the switching that goes through a loop for all instances of the movieclip copies (using the array with the IDs from the example above) and remove them.
