Actionscript 3 :: Get An XML Object Reference Instead Of Value In It?
Nov 4, 2010
I need to get a pointer to a piece of XML. I can get a pointer to the parent node and everything works but trying to get a pointer to a node that has no children just returns the value of that node.[code]...
Tracing subNode would be just the value and there is no pointer to the original xml object, so editing the subNode var would only change its value, not the one in the original XML object.
How do I get a pointer to the subNode so it can be edited to change the original xml object?

I want to print the content of the label property in the Alert window.[code]...
But the Alert window is completely empty. What am I doing wrong ?
I guess the keyword "this" is referencing the application instead of the LinkButton, right ?How can I reference the LinkButton itself, without having to add an ID to all my linkButtons?

I am new to Flash but have used Illustrator and InDesign for years. How to set the reference object by which all other objects are aligned; e.g. Illustrator ->select all objects then a second click on the reference object and all other objects take their cue. InDesign you lock the reference object and that determines the rest. In Flash it seems that either both objects move or the one that I wish to remain in position jumps rather than the other way around.

classes. GiftMain and GiftItem. i attached GiftItem objects into GiftMain. Actually there are 2 more movieclips between them. i declare a variable in GiftItem as giftMain to reference it to the GiftMain. i have a function in GiftItem which is as below;
[Code]...
trace outputs the right object in this function in GiftItem class but at another place in the same class, it outputs undefined when it is traced even though it is global variable. I just want to reach GiftMain from GiftItem without using _parent or _root. How can i do that?

I am modifying some Flex code written by someone else. There is an mx:text control that I want to change the 'text' property of. I know how to do this within the .mxml file in which the control is defined, however I don't know how to do this from within a separate .as ActionScript file. I recall in Flash there is some way to fully qualify the reference by prepending the stage or something like that

I have some object, which extends movie clip:public class MyClass extends MovieClip Now, I want to put two of this in the stage:[code]That would put one, but the other I want it to be exactly the same as the first, so I just need to add a "reference" of obj to the stage, along with obj itself.In the end, I want two objects of type MyClass doing the same thing in the stage. If I try to simply do:[code]only obj2 will appear in the stage.How could I achieve that with references? (in order to save memory and CPU time (it is really important))

Is it possible to reference an object using a variable value?
For example, I have a function that is supposed to hide an image and add that image to an inventory list when the item is clicked.
All the image info is stored in an object (name, imgSource, visible, x, y);
I was thinking I could do something like this:
<fx:Script>
<![CDATA[
public var item:Object = new Object();
[Code].....
I want "item" to stand for knife so that I could change knife.visible, knife.xPos, ect.

I'm creating a bunch of movieclips, associating a sound object with them, and then updating them with a progress bar, like so:
var theClip:MovieClip = new MovieClip;
theClip.track = new Sound;
[load sound from URL pseudocode here]
theClip.track.addEventListener (ProgressEvent.PROGRESS, onLoadProgress);
function onLoadProgress (erogressEvent):void {
How do I reference the movieClip the sound is a child of? e.target refers to the sound object; e.target.parent returns an error. And you can't assign properties to sound objects.

On the stage there's an empty clip called mc1in the library there's a clip called with the class name Ballnow every frame this functions is executed:mc1.addChild(new Ball())inside ball, at frame ten:this.parent.removeChild(this)so this creates a bunch of balls on the stage, but after a while this error shows up:TypeError: Error #1009: Cannot access a property or method of a null object reference.t Ball/frame10()Edit: ok by tracing Ball's name I understand that even though the Ball is removed it continues to exist somewhere?

I'm animating some mc's at the beginning of the timeline with AS3 (mostly alpha fades), but then I have some tweened animations further down the timeline and a "naviagation bar" that's on all frames, so a user can click a button and jump to a part of the timeline to see some other animations.My problem is that if I don't wait to see the programmed animations at the beginning and just clicka button to see the other tweened animations, I get an error:
"Error #1009: Cannot access a property or method of a null object reference. at flash_fla::MainTimeline/tube_glow2_animate()"
(tube_glow2_animate() being the name of a function)

My movieclips are being nulled when moving between scenes, they are created on the stage and accessed through as3. I have login screen with three button, one logout, one exits the system and the other takes them to the next scene. When going back to the login scene, and trying to access movieclips like add eventlisterners etc... it comes back with null object reference, claiming that my buttons which are on the stage are null and sure enough if I debug they are. Any reason why my movieclips are being made null when moving between scenes?

There is an instance "instance140" off of the root, that has an element named img4 that i need to reference... does anyone know how I would go about that? using root.instance.object form returns undefined.

So ive made the switch from AS2.0 to 3.0, and like many fellow casual flashers, I'm having a bit of a tough time
I understand that below, the first trace works because the mouse event comes from the clicked object, and that the second produces an error because the ENTER_FRAME event is attached to the stage, so e.target is the stage. i realise i can attach the listener to the obj, but i need it on the stage for what im doing
How can i reference the clicked object from run() ?
ActionScript Code:
obj.addEventListener( MouseEvent.MOUSE_DOWN, doMouseDown );
function doMouseDown(e:MouseEvent):void {
stage.addEventListener(Event.ENTER_FRAME, run);

I'm new to AS3 and I was making a game of chess. Basically whenever you click a square with a chess piece, I assumed it would be like java, and you'd be able to create an "ActionListener" that would pass a reference to a square that was clicked.
My question is this: How can I access this square object that was clicked in my array?[code]...
