Flash :: Removing Sprites From Stage
Sep 19, 2010
i created 5 pages, each of which contains several movie clips (text, graphics, forms, etc). There is one specific page however that contains autogenerated content via. sprites. If i happen to land on this page, the sprites will appear, but when i transition to another page, they are still there except for the non-sprite stuff (disappear). Im ripping my hair out on this one, i managed to get a few of the sprites to remove but some are still appearing. Below shows the layout of the one thats not being removed;

I'm making a picture gallery. I have a thumbnail container, which contains a mask and a dynamically generated mc called "thumbnail_mc". Thumbnail_mc contains all the sprites of the thumbnails.When I click on a thumbnail, the thumbnail get's a glow filter added to it. Now, I want to remove all filters on all the other sprites before I apply that filter to the Sprite.
This is what I'm trying to do:
Code:
thumbnail_mc.children.filters = [];
How do I do that?

I'm having two problems. First off I'm trying to remove container0 on roll out, but I can't remove it from the outView function because it doesn't recognize it.
Second these functions load another image on top of the thumb0 and it disappears right away. I don't know why and I'm trying to stop it from loading 2 instances
var container0:Sprite;
var loader0:Loader;
var boolean0:Boolean = false;

I am setting out for a visualization project that will generate 1000+ sprites from dynamic data. The toolkit I am using (Flare) requires some optimization. I am trying to figure out some optimization techniques for Flash. How can I make Flash run fast when there are so many sprites on the stage, or maybe there is an optimization technique that doesn't involve generating so many sprites?

i have the ingame sprite and it needs to be in StageQuality.LOW due to some prerformance problems, and the hud needs to be in StageQuality.HIGH... but they are in the same stage. I tried changing quality before rendering the ingame (to a big bitmapdata) but changing this property every frame is too expensive.

I have an AS2 swf that loads FLV videos into a FLVPlayback component and attaches a seekBar component. When the video stops I unload the seek bar from the screen and set the FLVPlayback.seekBar = null. When another video is to be played I set up the seek bar again by attaching the seekBar component to the stage and assigning FLVPlayback.seekBar = newSeekBarInstance.
[Code]...
What Im noticing is that sometimes the seek bar is removed from the screen and sometimes it isnt? I cant seem to notice any pattern here. Has anyone had similar problems? Do I need to force garbage collection?

I need to remove every object that is part of an array from the stage. What I have right now only removes one of the objects.
this.removeChild(enemyList.splice(0)[0]);
I've tried several variations of this with either the same result or an error. Also, what is the zero in hard brackets for? I haven't seen that in many tutorials/explanations, but when I take it out, I get all kinds of errors.

I have a timmer on the Main Stage, I want to Call Multiple Sprites to stage, in order, one after the other, and remove them when the Tweens Inside them are complete. The the first two Sprite's containing sample text do display, yet the third does not.
I need to call many sprites to the stage. But I need them to display and then remove from stage.
function Main() {
var newBordText:GoldBordText0 = new GoldBordText0();
addChild(newBordText);

This code creates a two arbitrary sprites, box and circle, and puts them on the stage. The circle is the child of the box.The purpose of the code is to enable the sprites to resize when the stage is resized. But the sprites only change size when the stage is smaller than their original size. When the stage is big enough, the sprites don't get any bigger than their original size. Throughout, they maintain their proportions.[code]

In AS3 on Android is it bad from a performance perspective to attach mouse event listeners to individual sprites rather than to the stage? I am writing an app for an Android phone using AS3 in Flash Builder. The app has multiple screens that respond to user touch. The screens are arranged in a hierarchy and show list data so that when you click on an item in a list you are presented with a new screen with a new sub list on it.
I have been using an event listener to detect mouse / touch input and based on something I read that indicated that performance is much better if you keep the number of objects you are listening to to a minimum I have attached the mouse listeners from each screen to the stage object.
This all works fine but I am finding that as I move between screens (and they get popped or pushed onto the dislay stack) I have to keep track of alot of adding and removing listeners to the stage object. If I don't then windows higher up the hierarchy than the current screen keep receiving mouse events.
If I used listeners attached to sprites in each window then when the window was removed from the display even though it is kept in memory (ready to be popped back when a child window is closed) it won't receive any mouse events....
Performance doesn't seem to be impacted using listeners directly on sprites when using my HTC phone to test with, however I obviously don't know what it will be like on other phones. Does anyone have any experience either way or a view on the best approach?

I have a main. fla with navigation btns activated by GoToFrame actions. Some btns load content and some use the UI loader component.
I have one btn that calls a UI loader "loaderVideoGallery" which loads an external .swf inside that .swf is an flv player "flvPlayer".
This also works fine except after that button is selected and that swf is on stage no matter what button you call next the video stream from the flv does not stop, it continues to play.
The UI loader removes itself as you can see the other loaders come up on button presses but the video's audio still plays.
the UI Loader instance is "loaderVideoGallery" and the .flv player inside the external .swf is flvPlayer
I was told to use
MovieClip(loaderVideoGallery.content).flvPlayer.st op()
I would think that the logical place to put this code would be inside the btns where the EventListeners are, is that correct?

I wanna remove everything from stage if i click on an image. Well it ain't that hard but there is one problem. I want to leave albumbg on stage but it's a child of bg and if i removeChild(bg) it will remove all the childs of bg so also albumbg. The problem now is, if i set the albumbg to addChild(albumbg) it won't show up.
Code:
package {
import flash.display.MovieClip;

I am making a little drag and drop game where you click on a movieclip, which acts as a button. When the moviclip/button is clicked a duplicate of that same movieclip, only larger, is added to the stage. You then drag and drop it in a designated area on the stage.
I have that part of the code working fine. What I need is a reset button that removes the larger movieclip that was dragged. I am not sure how to do this.Below is my code that is working fine. In the code I am the movieclip instance is named "myMC" and its class is "MyMC".
myMC.addEventListener(MouseEvent.MOUSE_DOWN, moveMC);
function moveMC(e:MouseEvent){
var newMC:MyMC = new MyMC();
[code]....
I tried removeChild for (myMC); and that removed everything. I only want to remove the second larger duplicate movieclip "newMC".

I have a main timeline which loads swfs in certain frames. It all works great except when I select one of the swfs that has a flv video inside. When I try to select any other frame the swf unloads but the audio stream remains.
Here is what I have
var Xpos:Number = 0;
var Ypos:Number = 0;
var swf:MovieClip;
[Code].....
I will have 3 more swfs with videos inside which I did not add yet as I need to get this sorted first.

So I have a 5 page website, on the home page when I opens you see a video and it automatically plays. When you click to a different page though you can still hear the sound in the background. The video has an instance name of video, I tried using video.stop(); in the code for each button and it works but then it doesn't allow me to navigate when it isn't away from the home page.Here is the code I have for one of my buttons (it's the same for the others with different names though):
home_btn.addEventListener(MouseEvent.CLICK, gotoFrame);

I am pretty new to actionscript 3. I want to remove the movieclip on the stage and add a new movieclip but the button is within the currently running movieclip that I want removed. I am trying this function
homeArtist_btn.addEventListener(MouseEvent.CLICK, newArtist);
function newArtist(e:MouseEvent):void{ removeChild(homeAni_mc); addChild(artistAni_mc);}
I get these errors

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 placed a movieclip on the stage, what functions are there to remove it?
removeMovieClip(target);
Only seems to work on MCs which have been attached to the stage E.g.
attachMovieClip();
The _visible property keeps the movieclip there just keeps it invisible. What completely removes it? It is called tankCPU.

I made a game where you have a bunch of enemies coming at you from the top of the screen and you move your mouse to avoid them but now i am trying to add a shooting ability and I tried using the code
if (shipenimy.hitTestObject(bullet)){
removeChild(shipenimy);
}else { }
but when this happens it removes the child from being displayed but even though it is not displayed if you go to where it would be it still counts it as a collision and will end the game even though the child has been removed and I need to find a way to completely remove it so that there is not a chance of running into it after you have shot it.

In my .fla file, I have a MovieClip (we'll call it Clip1) linked to a corresponding class defined in a separate .as file.There's a case where I want to create a new MovieClip (Clip2) where Clip1 is, then remove Clip1. This case is dealt with by a function in Clip1's class.So, when I get to removing I do:ActionScript Code:this.parent.removeChild(this)Now, if the DocumentClass created Clip1 and placed it on the screen, this goes fine. But if Clip1 was placed on the stage in the .fla file (by dragging and dropping), it looks like Clip1 is not removed. I think it does get removed, but for some reason it gets recreated. This is the problem.

I have a main timeline that has labels for different pages. On certain labels I have swfs loading using the UI loader with each swf removing itself while another appears. In some swfs I have .flvs called the same way and my problem is when an swf containing an flv is called the flv plays fine but soon as I select another frame the stream remains. How do I remove the stream so the next frame can play by itself?

I've got a project with a bunch of stuff floating around the screen (enter_frame moves them all around). I instantiate them with one function, and I want to have them removed in a separate function (all timeline code, no .as files). I want them to remove themselves after floating 500 px off screen. Here are the two I've tried:
for (var i:int = 0; i < this.numChildren - 1; i++)
{
if ((getChildAt(i).x < -500 ||

I'm trying a shooting game from an incomplete tutorial online. I'm trying to finish it off myself and hopefully learning more in the process but straight away I've hit a brick wall.The stage is 900 x 350. Bullets are fired from a turret near the center of the screen and will travel and eventually leave the stage at some point. I want to remove the bullet from memory and the display list once it has left the stage and can no longer be seen.I'm using a conditional if statement to check the x and y position of the movieclip, and if it outside the width or height of the stage then I want to remove it completely.
PHP Code:
stop();var angle:Number=0;var radiansToDegrees:Number=180/Math.PI;var degreesToRadians:Number=Math.PI/180;var currentTurretRotation:Number;var
