ActionScript 3.0 :: Identifying The Child In RemoveChild Action
Nov 23, 2009
I am creating a selection of checkboxes that are supplied from XML. These checkboxes are to provide additional details to a background picture and therefore they each have a unique name and an eventlistener to add the extra details to the background picture. Depending on other buttons clicked on the stage, the list of checkboxes could change for the same background picture. I have a selection of 5 different background pictures all of which have a different list of checkboxes. I therefore want to load the checkboxes dynamically. When a button is clicked to change the background picture, I want to remove all the checkboxes associated with that picture and display a new set for the new picture.

I have an issue where removechild won't infact remove a child. I think its something to do with my dropTarget.parent issues. The concept of the code is that you drag a source onto a destination. When you drop the source onto the destination you will get a text field that says "Hello" or "Goodbye". The objective i want to achive is that once i drop a source onto the destination, removechild will remove any previouse textfields added. This is proving difficult.

I got a Parent Sprite, let's name it SpriteP, which holds inside it two other Sprites. Sprite1 and Sprite2.[code]Sprite2 is a rectangle. When I rotate it, of course, the height of its parent, SpriteP, GROWS. But I would expect that height to go back to what it should be when I'm removing Sprite2!And it does! If I remove Sprite2 while NOT being rotated, the height of the parent drops back to normal, 200.

I got a Parent Sprite, let's name it SpriteP, which holds inside it two other Sprites. Sprite1 and Sprite2.
When Sprite2 is NOT rotated:
Code:
trace(SpriteP.width + ' ' + SpriteP.height); //100 250.
SpriteP.removeChild(Sprite2)
trace(SpriteP.width + ' ' + SpriteP.height); //100 200. -> works, 200 is good.
When Sprite2 is rotated at 90:

And it does! If I remove Sprite2 while NOT being rotated, the height of the parent drops back to normal, 200. But if I rotate Sprite2, the Parent won't update its bounds.

I have a DisplayObject, called myView nested in a DisplayObjectContainer called myContainer. myView is the only child of myContainer.I add a REMOVED_FROM_STAGE EventListener to myView, and call myContainer.removeChild(myView). The onRemovedFromStage Event fires for myView when it's removed from the stage, HOWEVER, myContainer still has a reference to it as a child on its display list! myContainer numChildren is still 1, and that child is still registered as myView!!! what circumstances this could be happening? I realize that there may be a reference to it somewhere causing this strangeness, but if the REMOVED_FROM_STAGE event has fired, shouldn't it follow that myView has been removed from myContainer?

I'm working on a game where I'm adding a symbol (an enemy unit) from the Library via addChild() to an instance on the Stage. The symbol has Linkage/Class enabled so I can stick stat variables directly on it for easy access.The problem is that I want to use the same name for enemies (like en0, en1) in different areas, but if I try to removeChild(), I get Error 1067: Implicit coercion of type Class to type DisplayObject.

if you view my project you will see that it is a drag and drop application. You will also see two buttons at the bottom (I plan on adding more), when you click on a box it will add more objects to the menu. Heres where my question comes in, the box then says remove on it, I want the items that were added by clicking on the box to be removed as well as items added to the stage when you click on that same box again, how do I do this?

My issue today is a DisplayObject error I'm getting when remove a child object. I have code that will launch(addChild) a video container and video controls as well as add a close button. Now the close button works fine and everything, removing the video and controls and I'm able to choose another video again, but when you click close a 2nd time I get this error: ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.
at flash.display::DisplayObjectContainer/removeChild() So I've narrowed down the problem to where I remove the videoContainer (which holds the video object) My code to play the videos:

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 have an AS3 application which seems to be leaking memory slowly while running. I've been looking for a profiler for Flex 2 / AS3 and haven't been able to find one yet, in fact I saw posts from people at Adobe saying they were working on it but no release in the short term!
Does anyone have any more news on this, or more usefully have any information on a profiler or other way it is possible to find memory allocation and usage during runtime of an AS3 application? It would really help me to identify what areas of my application are leaking memory.

I am trying to produce an auto check on the synchronizing process between XML values (string based by nature) and object properties.
E.g. if the property on the instance is of
Code:
public var isThere:Boolean
public var anum:Number
the code should know the type and adjust the property value
Code:
isThere = Boolean(xmlValue)
anum = Number(xmlValue)
Its all swell apart from Arrays, which mainly are identified as 'object'.
Anyone know the best check to differ between Array and Object?

I have 16 layers of movieclips (one in each layer), each has been given the instance name, "line1" through to "line 16". I'm trying to figure out how to hide all of them through actionscript, so far, my code is:
for(x=1; x<17; x++){
line[x]._visible = false;
}
but for some reason, it doesn't hide all the instances. I've tried typing it in seperatly, (line1._visible = false; , line2._visible = false; , etc...) and it works, but for some reason, when I use the for loop, it doesn't work..

I've been scouring the web to see how to do this, and now I'm not even sure it's possible. However, it seems there must be way. What I want to do is create a function that will take x,y coordinates and tell me what MovieClip or Sprite is at that location. I want it to happen automatically, without any MouseEvents or anything like that.

I want to identify specific strings in a text box from user input to add to a score variable, like so -
[Code]...
The example given adds 1 to the score, but if a user adds a space then a second word the text box views it as a whole and not individual words, resulting in no values added to the score variable.The problem lies with the whole text box being viewed as one entire string. Instead, I want to split it up so word1 will add 1 to the score, word2 will add 1 to the score, etc.

I want to do something where I collect functions to be invoked later when a certain condition is met. E.g.
function doSomething(someArg:Object):void {
if (conditionIsFalse){
operationsToDoWhenConditionIsTrue.push(function(){
doSomething(someArg);
[Code]...
Basically if doSomething is called twice, I only want operationsToDoWhenConditionIsTrue to hold the most recent invocation. Obviously since the invocations are wrapped in function(){} all the functions are the same. Is there any way I can accomplish what I want?

How do I determine what objects are underneath a given x or y coordinate on the stage or within a sprite? Preferably, I'd like to be able to do this so that a class that extends Sprite and is a child of the Stage can determine what's underneath a given x coordinate of itself, regardless of position on the stage. This has to be done without user input.
I'm not clear on what methods might make sense for this. The hitTest stuff requires more info than I'm likely to have. Maybe localToGlobal, but to use that, I need to know what the objects are already. There are a finite number of them, so I could have them testing for this all the time, but that doesn't seem right and may not even get me what I'm looking for.

I have several array element each assigned to different symbols on the stage and now I have assigned one function (fcn1) for each element's MOUSE_OVER event as follows:.
for(h = 0; h < fields.length; h++)
{
fields[h].addEventListener(MouseEvent.MOUSE_OVER, fcn1);
[code]....
Now in fcn1, I have to identify which element the mouse was over it. I could not do this because I can't pass any parameter to fcn1 other than e:MouseEvent. And I tried to look the properties and methods of e:MouseEvent that might give any information about the source element (in this case, array elements).So far, only way out of this was I create function for each array element which in turn call fcn1 with appropriate parameter, but it is cluttery.

how can i find (possibly with flash ) the listing of sub properties for events?i would not know if sub properties even exist for an event if i'd not done a tutorial stating so.for example.
var listenerObject:Object = new Object();
listenObject.cuePoint = function(evtObj){
trace(evtObj.info.name); //how do i find out if such sub properties exists for events?
