ActionScript 3.0 :: Completely Removing Dynamic Display Object
Jun 24, 2010
To remove a dynamic displayObject completely you need
RemoveChild or removeChildAt(index)
Remove all the refrences to the displayObject
Nulling the displayObject
But this is my case
PHP Code:
//here recto is a MovieClip on stage
//I creat a dynamic display Object named
newMcvar newMc:MovieClip =new MovieClip();
newMc.graphics.beginFill(0x000000,1);
newMc.graphics.drawRect(0,0,10,10);
[Code] .....
is referencing newMc or creating a copy of it. I believe that it is refrencing newMc but I am not sure why nulling refrenceMc has effect on newMc.

In document class action script file I add a movie clip to stage using
Code:
public var square:Square
square = new Square
addChild(square)
So it adds square to stage.Then after sometime I want it to be removed. I call a function "removeSquare" also located in document class. It executes the following code. And it removes the square from stage visualy.
Code:
trace("proff that it's executed")
removeChild(square)
square = null
Then of course I want to add a square to stage again, using code I written at top of the post. And remove it again, and so on..But game is lagging more and more and more. So I guess that the square is not properly removed. If you need more details about my code feel free to say, I just written that since I really doesn't know what else should be important.

I have an application that uses a main class to control other MovieClips, adding and removing them as needed, most of them are separate screens or sub menus.
When I leave the main menu and come back to it later from another screen, certain animations and roll over buttons still play, which I don't want, I basically need the main menu screen to reset every time it is seen.
I read up on this and found out that removing the child doesn't necessarily remove it from the memory.
I tried setting the mainmenu to null before moving onto a different screen but this threw up an error, stating that the parameter child must be none null.
how to completely kill my mainmenu when it is not needed.
public function confSubMenuOneScreen():void {
subMenuOneScreen = new SubMenuOne();
mainmenu = null;
[Code].....
This is the example of code that removes the menu and adds another screen, with the mainmenu = null code that throws up the error.

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.

When I'm removing an object from the display list (via removeChild), I'm performing a splice on all of the arrays that the object has:
[Code]....
My thinking was that this frees up some memory similar to disposing a bitmapdata. Does this even do anything? Or, will arrays be cleared and the memory usage restored when the object is removeChilded?

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.

I need to completely initialize a custom component in my Flex app (i.e. I should be able to access it from action script and get its properties and its children etc), But I do not want to add it to the display or make it visible. I have tried to add it to my visible component, but keep it visible, but often many of its properties are set only when it is drawn, so i don't get what i need. Is there a way to add a custom component to some sort of 'Virtual' display, that is not visible to the user?

Does anybody know an easy way to duplicate a display object (placed with addChild() to stage, containing a square which moves and scales and rotates randomly around), and make the duplicate mirror vertically 'everything'. As if it's a water reflection?
I'm only simplifying my case, in reality the display object has complex and multiple moving objects with filters.

If I create a rectangle with 100px width and 100px height and then rotate it, the size of the element's "box" will have increased.With 45 rotation, the size becomes about 143x143 (from 100x100).Doing sometimes like cos(angleRad) * currentWidth seems to work for 45 rotation, but for other bigger angles it doesn't.At the moment I am doing this:
var currentRotation = object.rotation;
object.rotation = 0;
var normalizedWidth = object.width;

I'm building a dynamic scoreboard for a client currently. The first application will be a golf leaderboard. It needs to be updateable by the client (I'll write a form that fills in the xml file from the users input)I need to have a xml file that defines..-number of columns/rows-titles-content in each boxand then the flash that takes that and generates a table from it.Is there any tutorials or source files floating around that do this? There's plenty that talk about in-game scoreboards, but we need to have all the data input from an external file.

I am working on a navigation for a page that consists of an image container, a text block, and a navigation. I have all the content in an xml file that is loaded and parsed placing each part of the site in its respectable spot. My question is I need to have the data for this site change when a button in the nav is pressed, so that the image and desc content is passed that corresponds to its button. this is in flash 8, as 2.0.

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 having some trouble with fully deleting object references. My object (a displayObject) has an ENTER_FRAME eventListener with weakReference set to true. It simply traces "hello" every frame. Then in my document class I try to delete it as follows:
Code:
delete(removeChild(obj));
. Despite this, the eventListener keeps on printing "hello". And I don't believe I have any other references to the object lying around. But in case that is true, is it possible to print the number of references of the Object?

Is it possible to create a completely dynamic menu by creating empty movie clips and loading external images into them? I'm experimenting with this, but it seems there is no way to create rollover/release functions for these dynamically created MC's.

i don't understand why none of my display objects are not being removed. when i press the button, i'm expecting a trace and removal of both shapes and the button, but nothing happens:

i realize there are better ways of accomplishing this, but i'm learning and therefore only interested in why the above code doesn't work.

I have an animation of footprints being left on the ground as if by an invisible man or ghost. the animation consists of:
1 movieclip containing --> 5 footprints each one is an individual movieclip. Each print fades in and out using the Tween class with an alpha effect
The main timeline uses the following code to create random instances of the animation:
var myTimer:Timer = new Timer(12000);
myTimer.addEventListener("timer", timedFunction);
myTimer.start();
[Code].....
so it looks like the function is being called correctly and removing the first instance of FOOT from the stage. but the 2nd iteration generates the error. Is this is a problem with the timer? I would like to send this to someone for examination and assistance.

why I cant kill a child in my display list. So I'm working on an ad that is going to load in different swfs depending on the link you click. What I wanted to happen is when the ad loads the first swf is auto loaded in to my container. Then when you click on the next link the new swf would cancel out the last one. What I am getting is an overlap of the swfs and I understand that. I can't figure out how to kill the other children. I tried unload and remove child but have been unsuccessful.

If you're removing a MovieClip from the display list, and that MovieClip in turn has child MovieClips which have their own event listeners, is it necessary to remove ALL listeners from the child MovieClips? or just the parent MovieClip that is being directly removed from the display list?

I've asked this question before but had no answers... so here I go again I have a structure of objects: Top object A has as children (addChild children that is...) one or more objects B_1 to B_n. The B_n may in turn have one (1) associated object A' (Same type as top object, not displayed to begin with). When I click a B_n two things may happen:
1. If it has as associated object a A', put it on the stage (as child to B_n).
2. Otherwise it is a leaf and it does other things.
If '2' happens I want to collapse the tree, that is remove the top and all children of same type from being displayed. I thought a recursive approach should work:

For example, in the following code when I resize the green square, red is also resized. I wanted to resize only the green.

var sprite:Sprite = new Sprite();

Can you make one Bitmap Object (I'm using an external jpg) or something similar, and then display it many times simultaneously without creating a separate object each time?
Also, would they be easily removed or hidden?
I've got a little checkmark jpg graphic loaded here, but I'm not sure how to go about using it in many places at once.. I can only display it in the one place at any one time...
I'm thinking there might be a way to load the picture once, then use its bitmapData elsewhere in new display objects somehow, without needing to reload the image over and over?
