ActionScript 3.0 :: Delete Derp When The RemoveChild(derp) Is Calle?
Jul 24, 2010
When a sprite is removed from a displayObjectContainer, is the sprite deleted?
[code]...
When I call the 'delete derp' it says only dynamically defined properties can be deleted. So my question is, when the removeChild(derp) is called, does that essentially delete derp as well, or does derp still exist?
[code]...
Since 'herp' is locally declared and there are no references to it, would there be any way to get rid of it after the herpderp() function has ended?

All of the bullets are of the "Bullet" class and are stored in an array called "bullets" in the main class. When bullets exit the screen, removeBullet(bulletID) in the main class is called.
private function removeBullet(id:int)
{
removeChild(bullets[id]);
bullets.splice(id);
}
In my Bullet class I have an enterFrame listener that traces "stillHere". So as soon as a bullet is added to the main stage using addChild, "stillHere" starts popping up in my output panel.
My problem is that even after I call the removeBullet, "stillHere" keeps popping up in the output panel, which tells me that the object which I tried to delete is still sticking around somewhere in the memory.

I'm creating one sprite named 'holder' and I'm adding childs to it. finally I use sp.source = "holder"; NOTE: scrollPane is in stage, having instance name = sp, holder is AS created.
this works very good, but I need to on button press refresh data on holder. So I want to complete remove holder, so my function can recreate it with new elements and then define scrollPane.source = "holder";
How can I do this?
var holder:Sprite = new sprite();
holder.name = "holder";
addChild(holder); // this adds holder to stage
//
// add elements to holder

I'm trying to build a conditional statement that will addChild and removeChild at different Timer Delays. Before I go any further, I thought, I should mention that I'm usinig TweenMax to ease the alpha of ease Child from 1 to 0 and back during the process to imitate a fade-in/out.
I'm getting issue with only one line - inside a conditional statement.It's running "OK". The movie runs as I want it, but the remove/addChild transitions are not at the speed I want it at. I am getting an error message in the output, but other than that, the movie runs fine.

I am implementing a flex auto-suggest combobox - as the user types in each character: Consider the string 'Stackoverflow' and user input = 'st'
1) the data provider is filtered to show all items starting with 'st'
2) text is set to auto-suggest string such that the un-typed part is highlighted.
So for instance, the combobox text may contain st'ackoverflow', where 'ackoverflow' is highlighted using setSelectedIndex()When I hit back-space or delete, and check the 'this.text' value, I expect that the last un-highlighted character ('t' in the above case) gets deleted and the data provider is filtered to show all items starting with 's'. However the text property contains 'st', as before

I'm trying to use the delete keyword to remove nodes from an xml file and it just plain won't work.Here's a stripped down example of what I'm working with. Every node has a child named "deleteme". If its value is equal to 1 I want to remove it from the xml file. If its anything else I want to leave it be. The delete method is deffinately gettig call but it's having no effect.

I've created a MovieClip that opens other MovieClips. These MovieClips are galleries with example of my art and such. Within these gallery MovieClips there is a "close" button, which is actually another MovieClip.
the problem
Everything works except that when I open one gallery, then close it, then open it a second time, the "close" button refuses to work.
I thought this was do to my incorrect use of removeChild, but now I don't know.
This is made slightly tougher by the fact that closing the gallery involves playing a closing animation, so first I put the removeChild on the last frame of the gallery MovieClip. That had the same result so then I tried it this way.[code]...

I can't upload the file here because it is too big but I will post the code and a tutorial link plus the problem I've been having.
What the code does is, it gets an image and places it on your stage. This image you place there is reduced in size and when you click on it, it creates a magnifying glass effect.
It works like a charm and looks very cool but the problem is that when I want to go to another page of my presentation, the image stays there, this is because of the addChild function I'm guessing.
Once again, no problem, I just added this to the AS code of every page : removeChild.
You've probably already guessed it, this only works when the child has already been placed. If I go to my intro page and I place the code there it will give me an error since the intro comes before the gallery code. If I don't put the code there it only works if the gallery has already been loaded and I click on pages that come after the gallery.
So what I actually need is code that detects if the child has been loaded or not and if it has, it should be removed, if not, don't do anything.
U can find all the code underneath, it's quite a lot.

I'm trying to figure out why I can't remove the child of the meteors immediately after they have hit the planet or a building so that it would only damage the building once. When I try to just 'removeChild(meteorArray[k])' AS says that the 'object must be a child of the caller'. I'm not sure what that means, but I thought that the meteor was the child of the main document class.

I'm working on a pretty simple flash application which basically plays a music clip downloaded from a web URL, and makes a stick man dance. I have it all working fine, however, I've used the addChild function on the start button to add the mc onto the stage, however, when I applied the removeChild function to take it off again, I get an error telling me that it hasn't got a caller.Here's the script:[code]I've had my tutor look at it, and she can't work it out either, but I do get the feeling that she's not much wiser on Flash than I am.

I've set up and button/movie clip array so that when a user clicks on a button, that movie clip loads and the old one goes away. What I'd like to do is use "addChild" to load the new movie clip and "removeChild" to remove the previous clip. I've got the addChild thing...sort of...it loads all the movie clips onto the screen at once though and I can't get the script to work another way.
Here's the code I've got:
var arrNavigation:Array = [{button:m1_mcButton, page:m1_mc},{button:m2_mcButton, page:m2_mc},{button:m3_mcButton, page:m3_mc},
{button:m4_mcButton, page:m4_mc}, {button:m5_mcButton, page:m5_mc},{button:m6_mcButton, page:m6_mc},

i have a quick question for you. Say i have a parent movieclip called "bob". Within "bob," i have another movieclip named "steve." within "steve," i have a bunch of other movieclips. Say i call removeChild(steve), from within bob. I know that will remove steve, but does that mean all the little movieclips within steve will be removed as well?

I have a MovieClip that loads other MovieClips. These I refer to as Galleries as they display some of my different web and art work. Each of these galleries has a close button (actually a MovieClip...) which works well enough. However I find that if I close a gallery and then re-open the same one, the close button refuses to do it's job again. The gallery remains open.
I'm pretty sure this is because I haven't used removeChild correctly. I knew I had a problem with this before, but thought I had solved it. Since, when the galleries close button is clicked, it plays a closing animation I couldn't figure how to add the removeChild for the MovieClip. This is what it looks like (including my commented out failure...)
ActionScript Code:
vectorGallery.close_mc.addEventListener(MouseEvent.CLICK, closeVector);
function closeVector(e:MouseEvent):void{
vectorGallery.gotoAndPlay("close");
/*if (photoGallery.currentFrame == photoGallery.totalFrames){
removeChild(photoGallery);
}*/}
ActionScript Code:
this.parent.removeChild(this);
at the last frame of the gallery MovieClip.
But I think I'd rather do it correctly.

You have two arrays, both containing a different set of movieclips. You drag a movieclip form one array, in to one movieclip of the other array. You can do that as many times as you like. So in fact, the movieclips in the second array are all droptargets. The thing is, I have one erase button which should erase all the movieclips from the first array only when they are dropped on the droptargets from the second array. In other words.. how do I remove the content of the droptargets without removing all the droptargets as well?

when the start button pressed I would like to add the 'start_mc' and remove the 'score_mc' if it is on the stage and when the score button pressed I would like to add the score_mc and remove the 'star_mc' if it is on the stage. I don't really know how to go about this without any error.

So, I'm running through a bunch of children in a container, doing stuff to them, then removing them from the container. Since I have both the index and the object reference, would it be better to call removeChild or removeChildAt? I'm leaning toward removeChildAt, but I don't know what's happening behind the scenes, and it's possible that one is just calling the other. Here's the loop:
Code:
for (var i:int = container.numChildren - 1; i >= 0; --i)
{
var kid:CustomClass = container.getChildAt(i) as CustomClass;
if (kid != null)
