If I set an Object = null, does that remove all references to the Object's variables assuming there are no external references to said variables? Or do I have to manually set all said variables = null?
View 4 Repliesthe script i wrote is working fine. but the script attached to the flash player which i have no control over is throwing a script error (im using IE8).how can i fix this? if i run it locally there is no error.
'null' is null or not an object
try { document.getElementById("").SetReturnValue(__flash__toXML(function() { return document.location.hostname; }()) ); } catch (e) { document.getElementById("").SetReturnValue("<undefined/>"); }
but this is from flash script and i dont have control over it. it just say JScript - script block.
If I have a variable that is declared within a method of a class, should that variable EVER need to be marked for garbage collection (set to null).
For example:
Code:
public class MyClass extends MovieClip{
public function MyClass():void{
//constructor
myMethodThatLoadsAPage();
}private function myMethodThatLoadsAPage():void
[Code] .....
I am making a 24/7 kiosk app and am noticing that the "pages" I load from the library using the above technique continually increases the memory usage (using Monster Debugger 3 and testing the SWF from within Flash Pro CS5 on a Mac.) As I understand it "myVar" are the only references to each "SomeObject" object that gets instantiated. Shouldn't the fact that myVar is local mean that SomeObject should be available for garbage collection after each new page is loaded?
I have the following piece of code(part of a much bigger program). I this code I am re-using a motion that has been previously used successfully. The trace stmts are used to identify the exact location of the error and the error conditions as best I can.[code]
View 4 RepliesWhen you cast null to an object using Object(null), the result is an object.When you cast undefined to an object using Object(undefined), the result is an object.But saying null as Object or undefined as Object remains null.Why is this? I can't find anything in the documentation about this.
The objects that result from these casts can have properties set on and read from them. It's as if the cast created information, or removed whatever special information the null and undefined values have. But there's no indication in the AS3 documentation that the null and undefined special types are actually objects.
I am trying to add an EventListener to a MC, but I am getting the 1009 error. My script is referencing a MC that does exist. I have verified that my code is typed correctly, and that my instance names are correct.I am creating a portfolio site. On the first frame I have my main navigation (well, it's actually not the first frame. I alpha-fade everything in so it's really the 6th or 7th, but I'm not sure how pertinent that is). The main navigation works fine (5 movie clips, fyi). Clicking them will move to a different frame, and the information and sub navigation for the frame will fade up. It is the sub navigation that I am having trouble with.[code]
As you can see, it doesn't even get to the function before it gets thrown off. I have verified that the instance names are correct. The script and the MC I am trying to add it too [I/]are[I/] in the same frame, which is what's stumping me. Normally you get 1009 when the object you're trying to reference is not there, but mine is!!Obviously there is something wrong with my EventListener. I am not sure what else do; there is a gap in my understanding of AS.
I have an object which is assigned a number of properties:
var project_array:Array = [];
var slideObject:Object = {
project_title : myXML.projects.project[i].title.toUpperCase(),
[Code].....
but I'm not quite sure where to place this. If I place it outside of the object constructor, I get "term is undefined", I guess because it doesn't know what project_clips_array is - but if I declare project_clips_array in the constructor, it appears to need to be defined, i.e. I can't create a blank property. But I can't place it in the constructor either, because it doesn't seem to allow me to run a function within an object constructor. What is the proper syntax or arrangement of code for executing this function to get the array within the object?
i am trying to access an object within a class and the object is comming up as null but i dont understand why.
this is the object:

i am trying to access an object within a class and the object is comming up as null but i dont understand why.this is the object:

addChild(btnLMain);
this was created in the class: LanguageButton. here is how i declared the above class within the class i am trying to instantiate it:
var btnL:LanguageButton;

btnL = new LanguageButton(cssLoader);
main.addChild(btnL);
btnL.btnLMain.addEventListener(MouseEvent.CLICK, btnLClick);

I am getting this error, randomly when I start my application (and it's sub applications). As you can see the stack trace is rather useless, although through the debugger I can see the parent of container (second in the stack) is an MXML class that has a repeater that repeats another component. Therefore I guess the component with the problem is that repeated component, although I am unsure what I can change to stop this from happening. If anyone can give me some insight to the FocusManager or the getFocus() function it would be really handy.[code]

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:

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?

I have a test main.swf with just a UI loader component loading in an external .swfThe swf is a flash scroll using the component class. The swf works fine on its own but when used with the UI loader I get an null reference msg.The files have xml, .as and css files in the zip.light on why I get this reference as the scroll and text appear in the main.swf but the scroll does not function.
View 3 RepliesI have a movieclip that I add to the stage and Im trying to reference a input text field on the second frame.When I trace the textfield on the first frame via the constructor it returns object textfield correctly.When I hit the enter button to go to the second frame where I will need to use password... I get a null when tracing. I can see it, I can write in it and no matter what I do I cannot seem to reference it.
Code:
public function Registration():void
{
trace(this.usernameField); //returns textfield correctly[code]...
In case you need the parent of registration its just the document class and I create registration like this..
Code:
var registration:Registration = new Registration();
addChild(registration); //ive also added it to the stage w/ no luck
