ActionScript 3.0 :: How Would These DisplayObjects Be Garbage Collected
Feb 3, 2012
there is a Class A, it has a timer which updates its x position periodically. So all the instance of Class A will update their own x position. There is another Class B which extends Class A and overrides the function which updates position to change y position and call the trace function.
Now what I do now is create two instance alpha1, alpha2 of Class A and other two instance beta1, beta2 of Class B.
- alpha1 is only instantiated, but not added to the stage.
- alpha2 is instantiated, and there after added to the stage.
- beta1 is only instantiated, but not added to the stage.
- beta2 is instantiated, and there after added to the stage.
- let say after few seconds, I remove alpha2 and beta2 from stage.
Now suppose the GC fires collection, who all would be collected ?

I just noticed a strange behaviour while looking at my application in the Flash Profiler. When I click a button in my TitleWindow then the TitleWindow doesn't get garbage collected after it is removed. I have no idea why that is happening.[code]...

I have checked and rechecked, and I do not know why these "buckets" aren't being killed when I run the reset menu function, a fresh set of eyes could really help.
Code:
package com.Views {
import flash.display.MovieClip;
import flash.display.Sprite;
import flash.events.Event;
[Code]...
i'm sure there are a lot of problems, but the only one I care about is destroying those buckets. inside the buckets, I have a listener for "removed from stage", and that kills all the listeners, etc, inside the buckets.

I have that function in the class:
private function fireItemCreated(data: ByteArray): void {
setTimeout(function(): void {
var event: ItemCreatedEvent = new ItemCreatedEvent(data);
dispatchEvent(event);
}, 1000);
}
This function called to dispatch item created event when image thumbnail created.But it delays event on some time to prevent user interface freezes. And I'm guessing what could be happen if garbage collector executes after fireItemCreated function call but before timer event. Does the closure will be removed or it stays until it will be executed?

I recently posted on here about tweening in alphas of thumbnails that I was adding to a movieclip. It seems that the tween is getting garbage collected because not all of the thumbs fade in all the way. I have the tween defined outside of the function, but it is tweening a loader that is created within the function. Could this cause the tween to get garbage collected? if so, how do I fix it?
Here is the pertinent code:
var thumbTween:Tween;
var my_thumb:Loader;
function thumbLoaded(e:Event):void{

I have had a few complications with syncing the notes coming down, then I realized tweens would be the best way to go, so I chose them.The problem is; the notes come down the screen. If there is any lag in performance, any note that is on the screen freezes on the spot, and the new notes come down, and stay in sync.This is telling me it's something to do with the tweens. The timeOuts I have set work fine for spawning notes at the right time, but the tweens are freezing on occasion, Im guessing because the timer for the tween keeps going, but flash does not notice it.Here is the code for adding the notes:
Code:
var myTween:Tween;
var timeWindow = 1;

Consider the following segment of code:

Do not worry about the syntax of this code. Here is my concern - The loader object which is used to send the HTTP request and which has the onLoadComplete event registered to is not referenced from outside the loadSomeContent() function. Is there a possibility that the loader object will be garbage collected and loadCompleteHandler() will never be called?

can a loader get removed (garbage collected) whilst its still loading? does it have to be added to the stage or to an array?

This is the situation: I am trying to build an uploader that will take data collected earlier in the form before the upload occurs and then rename the uploaded file with it. I've gotten the upload itself to work, but thus far I have no luck getting any sort of renaming to work, not even by PHP. I tried Loadvars to transfer the variables over and rename it during upload, yet it says "NO" and rejects the post variables when the upload occurs. I even tried loading the variables into an external file and transfering them back to the uploader via cookie, all at the same time. Again it says "NO!", and the file is uploaded as __"filename".jpg. This is my code thus far:

I'm not sure if the debugger in CS4 has a way to display that kind of info. Is there some other way?

I've got a custom component (quite complex so I can't post any code here, although that shouldn't matter), that I can add to a view. When the component is deleted from the view or the view is switched I call my own dispose method which removes remaining eventListeners and kills some references so that the component can eventually be nulled and collected by the GC.
All that works perfectly fine until I add a Spark TextInput to the MXML part of the component (it took me hours to find out what is preventing the component to be collected!), so I recon that the TextInput somehow automatically adds some eventListeners.
My question is what are these listeners, or is there anything else I haven't thought of?

How can I use displayObjects as animation frames?I have six symbols in my library I want to animate with a timer. The advantage would be the ability to change the speed of the animations, and the elimination of the messy timeline.
The only drawback is the initial setup of the objects in the library. I've tried switch/case design patterns, visible=true, and z-depth, but I can't get it to work properly. Any answers?
//setup code
var timer:Timer = new Timer(100, 20);
timer.addEventListener(TimerEvent.TIMER, countdown);
function countdown(event:TimerEvent) {

I'm working on a world builder that will load a toolkit which is represented by an xml document. The document will look similar to the following:[code]Now, I want to be able to represent this structure in flash. Vertical layout is easy enough, simply placing the elements from top to bottom. It gets mind-boggling when I need to do the following:Be able to click any folder and have all its children hidden/shown.Position the elements horizontally based on hierarchical position (indent children of folders, children of the child folders, etc)Position the folders/tools vertically when folders above and in the same "directory" are hidden.It either sounds a lot easier than it is, or I'm missing a vital and obvious step.Just to save confusion - when I make reference to "folders" and "tools", these are a MovieClip which is a simple block with text over it, like:[code]

I'm creating my first AS3 project and I've already hit my first snag, nested display objects (aka buttons and movieClips). Let's say you create a movieClip and place buttonA on frame 1 and buttonB on frame 10. You create a class for that movieClip that tells it to jump to frame X after evoking a custom method. With the same method you want to assign the buttons on that frame their functions, but you can't because Flash thinks that DisplayObject does not exist. How do you make sure all DisplayObjects for a frame have been loaded, so that you can reference them?
I have figured a way around it by using the ADDED event listener. Apparently this event is triggered every time any DisplayObject is added, whether it is nested or not. What's interesting is the number of children (numChildren) for the parent movieClip stays constant. So, this code takes advantage of that fact.

I've got another interesting Flash issue, and I was wondering if there was some weird case I had to account for. Here's the code: var c:DisplayObject; var t:Rectangle; c.width = t.width; trace(c.width, t.width); This results in output of: 0 13 I'm expecting '13 13' as the output..what would cause this to happen? It's sporadic, sometimes it'll happen, sometimes it doesn't. Is there some weird race condition I should double check for?

I am adding DisplayObjects to a Canvas using
ContentContainer.addChild(c);
Where ContentContainer is my Canvas object and c is the DisplayObject I have created at run-time. Some of these DisplayObjects also have children of there own which are added at run-time prior to the DisplayObject being added to the Canvas.
I then need to iterate over all the children of ContentContainer but the first time I do this, it says that ContentContainer has no children (i.e., ContentContainer.numChildren = 0). If I do it again tho then it is fine and returns the correct number of children. Is there something I need to call to get ContentContainer to recalculate how many children it has?

I am very new to AS3, and I'm confused about how things that would have been simple in AS2 are so complex and tricky now. For example, I want to create a bunch TextField objects that, for some reason, rise up every frame (as in : object.y-=1; ).However, I also need each TextField to reference the TextField that was created just before it.
I tried creating a variable that would hold such a reference : ThisTextField.Ref=LastTextField; but - this returns an "Access of possibly undefined property..." error. It seems I can only have custom properties on mere Objects ! This is annoying because an Object doesn't seem to accept event listeners (remember, I need them to do something every frame). Is there a way to simply set custom properties on my TextFields, without having to use custom packages ? Or is there a way to use event listeners on Objects ? I've read something about strict mode which could allow setting properties on other objects - what are the risks of turning it off ?

ActionScript Code:
private function drawMap(tile1:DisplayObject, tile2:DisplayObject):void
{
var _tile1 = tile1;
[Code].....
The idea behind this is to store custom sprites in an array and then feed the array to the drawMap function, which would use the sprites from the array to draw a map.

why Bitmaps are not considered children of displayObjects (at least from my observations, I think this is true). They themselves are displayObjects so therefore should be part of the display list. In fact, when multiple Bitmaps are in one MovieClip, it recognizes them as one child, a Shape instance. Could anyone explain this to me? I'm attaching an example with a few display objects in a movieclip.

I wanted to use dispatchEvent inside the MOUSE_OVER event of a menu item, setting the event type to a unique label which another displayobject somewhere in the display list (NEITHER a parent nor a child of the event dispatcher) would listen for, so that it could brighten. See the following lines of code:
in menu item class MOUSE_OVER handler: dispatchEvent( new MenuEvent( xml.@label.toString().toUpperCase()+"over") );
in "site button" class constructor - the thing I want to respond to your hovering over the menu by brightening (which over() does) :
addEventListener( xml.@label.toString().toUpperCase()+"over", function( e:Event ) { SiteButton( e.currentTarget ).over(); } );
It doesn't work. I screwed around with capture and bubble parameters.
how to do what I want in a simple way? I spent 2 hours already trying to figure this out.

I'm new to ActionScripts and was tasked to complete a project. I'm trying to split a big image so I can send them to a http server in chunks. I'm using a recursive function below and increasing the DisplayObjects X position on every iteration. The problem is I get the same image in every iteration and checking the encodeByteArray string value is always the same.
Code:
var currentTileIndex:int = 0;
function renderNextTile(e:Event):void{
if(currentTileIndex < tilesToLoad){

Since flex memory management is poor, objects once instantiated dont die very easily (even when they go out of scope), one would need to check on various properties of components. I am using one such thing to know if the screen (which is a display object) is in current view. For this I am turning on a boolean property (currently visible), and I am setting it true on show event of the display object.
What I need to know is, which event (something opposite of show, e.g left?) could be used when the screen is replaced by another display object?
Something like focusIn and focusOut from dotnet.
Or if there is some property which could directly tell me if the display object is currently in view (hasFocus doesnt seem to be giving me expected results).
