ActionScript 3.0 :: Does Setting An Array Of Objects To Null Erase The Objects From Memory
Apr 27, 2010
I have an array of temporary objects created in a for loop. The objects are of type class "Tile", a class I created. However, it appears that whenever I create a lot of tiles in the for loop, the program slows down indefinitely.
While the array is whiped at a later trigger point, I am thinking that perhaps these Tile objects are not being erased from memory. They are being created on the fly in a for loop, and the array is being reset to "array = []".
Are the objects still in memory or are they cleaned up when the array is set to []?

I'm having trouble with my code. I keep getting this error
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at Test_fla::MainTimeline/frame1()
I believe it has something to do with the array, considering it works when I remove the array stuff. What I'm trying to do is to be able to move objects through an array with my gravitate() function in the Grav Class.
stage.addEventListener(Event.ENTER_FRAME,onLoop, false, 0, true);
for(var i:uint=0; i < numParticles; i++){
var p:Grav = new Grav(5, 0xff0000, Math.random()*250, Math.random()*250);
addChild(p);
particles.push(p);
} function onLoop(evt:Event):void {
//for(var i:uint=0; i < numParticles; i++){
//particles[i].gravitate(1,1);
//}}

I have a service which returns an Array of ObjectProxy objects. I would like to cast this to a custom object (a value object) and create an ArrayCollection. How can I do this?ited:I am using Django and PyAMF for the backend. I had to write a custom SQL query and I am wrapping the resulting records in ObjectProxy and sending the whole result as an ArrayCollection.Here is my client side code:
[ArrayElementType("SessionVO")]
[Bindable]
private var _list:ArrayCollection;

Is this the correct, most efficient way to recycle objects when creating an array of objects?

I have a class "Ball" which display graphical circle ball in random x&y axis and Ifade out it with Event.ENTER_FRAME and specify removeEventListener if it reach alpha<=0 .Now I made multiple object from "Ball" class. Now, In my stage it works nice but when I see my Computer Memory status. my current flash.exe is increasing memory rapidly. Is how to remove my unusual object from my Memory. So that it would not get hang.

I tried to include a free photogallery based on as 3 in to a free flash template site. Now, if u click photogallery, the photogallery have to build up!
I have following problem: -If u click the photogallery a second time, it doesnt work correctly! (I think it has something to do with the existing objects from the first call!.. The second thing is, it uploads the pictures for the gallery 2 times. So i have 40 picture instead of 20 (20 of 20 are the same :/)....
I tried this but with no succes: (i tried to remove the objects with remove child...Its the last part of this code)....

I am creating a generic button that will remove items created dynamically in a movie clip container from memory (not just from the display list).
To track which item the user has selected for deletion, I have a click function that stores the name of the clicked object in a variable called objName. I then store a reference to the object itself in another variable called targetObj. I can then easily remove the object from the stage like this[code]...

I'm trying to make a Starfield program as practice for ActionScript 3. I'm using a timer event in the document class to create Star objects which are defined by an object class connected to the movieclip Star in the Library. The object class has a timer as well, and at each tick it repositions itself a few points away and scales up, creating the image of a star shooting towards the sides of the stage. When the star has gone past the boundaries of the stage or when it has scaled to a certain size, it removes itself from the display list with the command: this.parent. removeChild(this);This removes the star from the display list just fine, however after that I can't get the star to set itself to null so that it will be removed from memory, and I'd like some suggestions on how to do this properly. An idea I had was to make a function in the document class that the child objects can call, something like this.parent.KillMe(this) which would give itself as a reference to the function, which could then use a local variable reference to set the child to null, removing it from memory. This all seems terribly complex, so I'm sure there's another way.
I haven't noticed a memory leak or slowdown, however, so I'm curious if objects without references that are removed from the display list are automatically removed? That could be both good and bad, as the object might want to add itself to the display list again at a later time; not in this Starfield program, but perhaps in another I write.

In my flash scene, I want to put several items off screen (to make things easier) which are going to rush through the scene (they are very big in size) but I worry that they might slow down the movie as it's playing.
But if I have things off the scene (out of view upon playback), do they affect the speed of the movie (affecting the memory and slowing things down)? To give you a better idea here is the scene: There is a vehicle moving quickly and the camera is facing the right side of the vehicle, so we can see the moving landscape behind the vehicle. I can either create a very very long landscape and movie it all one time (if having the long landscape off the screen does not affect the movie's speed), or I can create certain points of the movie where I ad and take away from the landscape.

My AS3 application basically does the following (pseudo code from main application class) 3 or 4 times by adding custom objects to stage:
_movieClipClassVariable = new MyCustomSpriteSubclass();
_movieClipClassVariable.addEventListener(MyEvents.READY, function(event:Event):void {
_hideLoading();
mcHolder.addChild(_movieClipClassVariable);});
_movieClipClassVariable.addEventListener(MouseEvent.CLICK, myClickHandler);
private function coverClickHandler(event:Event):void {
}
What is the right way to allow Garbage Collector to recycle _movieClipClassVariable after it is not necessary? Assign null to it? Remove all listeners? Use weak reference for listeners?

Is this at all possible? I just finished re-building my entire portfolio site in AS3 because I can't change the frame rate for loaded content in AS2. Now I find out after completely rebuilding this thing that AS2 content gets stuck in Flash Player 9's memory and won't erase on Loader.unload. All my work from years back is in AS2.

I was just wondering--and it's probably an obvious question really--if I make an object null and that object had one or more event listeners registered, are the listeners removed?
for example:
Actionscript Code:
object.addEventListener(Event.SOME_EVENT,callBack);
function callBack(evt:Event):void
{
object = null;
[Code].....
In this case have I removed 'object''s listener when I made the object null?

I'm working on putting together a game at the moment which is similar in many ways to mini golf (or crazy golf, depending on where you come from). It is shown from a side-on view and to play the user must select the ball by holding the mouse down over it, then drag the mouse to indicate the direction they wish to fire the ball in. The distance they drag the mouse (this is capped obviously) determines the power of their shot.
I am currently using a triangular object with the tip placed at the centre of the ball to show to the user the direction they have chosen. This triangle rotates to face the position of the mouse, and I'm trying to get it to extend/shorten based on the distance from the mouse to the ball. I have code in place (below) that works when the mouse is either to the left or right of the ball, but behaves rather strangely when the mouse is above or below the ball. When the mouse is in either of the latter locations, the triangle extends to be far bigger than the maximum length allowed by the program, yet a trace shows it is still within acceptable limits! I'm almost beginning to think that Flash is switching the 'width' and 'length' attributes around when the object is rotated by either 90 or -90 degrees!
The code I am using is:
[Code]....
Here's a couple of screenshots of the game as it currently stands too - please don't laugh at the horrible placeholder art: none of it is final haha (also note that I haven't implemented 'gravity' yet, so everything is sort of hovering in mid-air.) The first image shows the code working as I want it to with the triangle at it's max width, the second shows the triangle going 'huge.'

I have a flex application with two objects: a parent widget (called an IBaseWidget) and a child widget (called a HelperWidget2).When the user clicks on a help link, a helper widget is loaded into the list of base widgets and then displayed for the user.However, when I try to access this child widget by casting the base widget in the collection to the child widget type,the child widget returns null and I am unable to work with the widget.The following snippet correctly returns the widget ID of the newly added widget and dispatches an event to load the widget:
var id:Number = WidgetManager.getInstance().getWidgetId("Helper");
ViewerContainer.dispatchEvent(new AppEvent(AppEvent.WIDGET_RUN, id, openQuickQueryCanvas));[code].........
The problem is that helperWidget above always returns null, meaning the cast isn't successful.

I have an ASP.NET 2.0 web service and am using it in (among other things) an Adobe Flex application. I have a strange issue where if I send an object to the web service using soap with some fields that are null the webservice is actually creating new objects on the other end (and not putting any data in them).[code]In this example SomeFieldThatShouldBeNull and SomeFieldThatShouldBeNull2 are being created as new objects by the webservice. It is vital for the application that does not happen.

Hi everyone. This should be a simple question. Using flash professional CS5
I'm manually setting up stuff on the stage (authortime). And i've placed an object at a specific rotation. I now want to place another object, with the exact same rotation.
The problem is, i cannot find any way to read the object's rotation, or to specifically set it (ie: by typing in a value, rather than by manipulating editor handles)
I'm looking in the properties window and there's readouts/settings for position, size, scale, a ton of 3D properties, color effect properties, display properties, and filters. But there's no field for rotation. why the hell not! Isn't that a ridiculously simple and stupid omission?
so far the best method i can find is using free transform, and adjusting it manually til it "looks right", which is a very un-exact way of doing things.

I use this pattern to test for undefined and null values in ActionScript/Flex :
if(obj) {
execute()
}
Unfortunately, a ReferenceError is always thrown when I use the pattern to test for child objects :
if(obj.child) {
execute()
}
ReferenceError: Error #1069: Property child not found on obj and there is no default value.Why does testing for child objects with if statements throw a ReferenceError?

I've started dabbling in switching out the context menu and adding other functionality to it.I tried creating a new ContextMenu and set it to the property of my stage. No go, it says Stage does not implement this method or property. Which is kind of bizarre since Stage inherits from InteractiveObject which does indeed have the contextMenu property.
So I tried to just trace out the contextMenu, and it returns null on whatever displayobject I try it on. A MovieClip, the stage itself etc..What am I doing wrong? In my world, and according to the documentation, I should be able to change the contextMenu.

iSo let's say I have three different arrays of objects, and I want to combine them into one sorted array. I want the order to be such that the items from each array are evenly distributed throughout the sorted array.
If there were 3 xItems, 3 yItems, and 3 zItems, the sorted array would have this order: x, y, z, x, y, z, x, y, z
HOWEVER, even if the arrays are differing lengths, I still need to make them alternate as much as possible. If there were 6 xItems, 4 yItems, and 2 zItems, the sorted array should have this order: x, y, x, y, x, z, x, y, x, y, x, z
