If I dump a lot of sprites into a vector, then want to garbage collect and repopulate the vector, what is the best way to do this? My app will be reusing the same vector over and over and I'm a bit worried it may have performance issues.

I'm working on a flash game that has developed an obvious memory leak. I do what I'm supposed to do with GC; remove all references to the object, nullify it, remove all listeners (or use weak listeners); but the leak is still present.
I've stumbled across this article: [URL].. It claims that objects that are too large will never be garbage collected. This theory fits well with my project since all of my game resides in a couple of huge MovieClips that are created and destroyed often.
Is there any merit to the claim that objects that are too large will never be garbage collected?
I'm struggling a bit to fully understand garbage collection. To be honest I don't understand why this just can't be taken care of automatically but hey - I'm not a programmer so what do I know... Now to my question - I have the following code:
Code:
var format:TextFormat = new TextFormat();
format.letterSpacing = -3.5;
huvud_txt.setTextFormat(format);
Is it enough to set format = null; to destroy the format object or is there some crossreference going on here so that I need to do something more? huvud_txt is a textfield on stage - it's not created with code...
I'm wondering how to garbage collect a variable in Flex even if there are other objects binded to it.
View 1 RepliesI am creating drops, which is a movie clip
->drop: Drop = new Drop();
and adding those to the drops vector
->dropsVector.push(drop);
where,
->dropsVector:Vector.<MovieClip> = new Vector.<MovieClip>();
so for garbage collection,what all should i do?Splicing the dropsVector just splices the length to 0, but does not affect the memory.How do i empty the memory occupied by 'drop'?
I am implementing garbage collection within an AS3 app. In one part, several display objects are created within a loop like so:
for(var i:uint = 0; i <= this._exampleVector.length - 1; i++)
{
this._customText = new CustomTextObject(this._exampleVector[i].playlistText), this._customTextWidth);
[Code].....
When I try to make the _customText within the _customTextVector null, this does not work. It only makes the index inside the Vector null. how to do this or another method to garbage collect?
i'm trying to repopulate a list when you select a new category from a drop down component.
So far i can populate the category drop down and i can also populate the list box from a default dir but i can't seem to get the list to change when you select a new category.
this is the category script that populates the drop down (this is working fine except that when i change the category i want the list box (bgList) to repopulate with the new location files):
ActionScript Code:
loadCat ="textures";
if (_url.indexOf("http") != 0) catFilepath = "xxxxxxx/backgrounds/";
else catFilepath = "xxxxx/backgrounds/";

I'm creating a kiosk with a place for visitor's comments. There are several sections to the kiosk each with their own stand-alone .swf file (not browser based; no html). I'm planning on using Shared Objects to collect the input from the visitors in each section and these will periodically be reviewed by museum staff before actually getting posted. My question is, can I create one .swf for museum staff that uses an array to review each of the SO's created by the individual sections or will a flash file ONLY read in one SharedObject forcing me to create a separate app for each section for the museum staff?
View 1 RepliesI'm looking for a way to collect the file dependencies from Flex ActionScript and MXML files. I was hoping that mxmlc could spit them out (like gcc's -M option), but its option list doesn't seem to have anything relevant. I could write a parser, but would prefer not to reinvent the wheel if it has already been done, particularly given the two very different languages involved. In particular, star imports and in-package implicit imports could be troublesome.

View 2 RepliesI am currently being confused by the Vector class.I wrote a beautiful XML to TypedClass parser. Works beautifully and without fault. UNTIL a co-worker noticed we got a Conversion Error for Vector.<Number> to Vector.<*>.
Every Vector I've ever tested all extend Vector.<*>.
Vector.<Sprite>, Vector.<String>, Vector.<Point>, Vector.<Boolean>, Vector.<TextField>, Vector.<CustomObject>, etc etc etc. ALL of them.
<type name="__AS3__.vec::Vector.<String>" base="__AS3__.vec::Vector.<*>" isDynamic="true" isFinal="false" isStatic="false">
<extendsClass type="__AS3__.vec::Vector.<*>"/>
[code]...
But then when I use describeType on Vector.<Number>, Vector.<uint> and Vector.<int>.
<type name="__AS3__.vec::Vector.<Number>" base="Object" isDynamic="true" isFinal="true" isStatic="false">
<extendsClass type="Object"/>
<constructor>
[code]....
Now I have accounted for these 3 vectors individually as even uint and int does not extend Vector.<Number> as I would have expected.
And my parsing function works for all types correctly again. But my confusion comes as to WHY this is the case, and why I couldn't find any documentation on the subject.
Let a qualified-user place a dot on a country map and this dot will be shown on the map. When other users come by they see dot's and those dot's trigger a image.
1 Create a map, duh
2 Use the mouse to get the coordinates (_x and _y position) onRelease will be the selected coordinates.
3 Create a preview-scene were the qualified user sees the placement of his dot.
4 If oke, a image upload scene is triggered (the selected _x and _y coordinates are hidden)
5 The qualified user selects a image on his computer.
6 Again a preview scene, now with the dot on the map and the selected image.
7 If oke the user sends the coordinates and image to the server (i will use php-files to upload the info and a mysql-db to store the info)
I am stuck with step 2. In the attach file you can see what i have so fare.The trace messages are the data i want to send to a php script. And think i must create an array in flash something like:
Code:
coords = new array();
for (i=0;i<=v;i++)[code]...
You gotta see the attach .fla to understand this. I have the values collected in "controller" movieClip.

I just encounter a strange problem:
var a:ClassA = new ClassA;
var b:ClassA = a;
The program keeps running sometime, the a = null, b = null.
The program is a complex one, I am sure that no part will touch a, and b. My question is, will the runtime(garbage collector) to collect the memory of "a" and then assign a and b to null?
I have a large vector drawing (imagine 5000x5000) that i want to break up into separate pieces. I know that I can convert this vector drawing into a bitmap and then use the copyPixels method to create many separate bitmaps of the different regions of the original vector drawing, but is there any way to subdivide it into movieclips that just contain vector graphics instead of a bitmap?The reason im dividing a big chunk of vector graphics into smaller pieces is for performance reasons, so flash would only render a small part of this big chunk at a time (only certain regions/voxels/subdivisions are rendered at a time). But bitmaps apparently take up a lot of memory and the system im using would take much less memory if these subdivisions could be preserved in their original vector graphics form.
I imagine I could use masks somehow to achieve this effect (for each subdivision, duplicate the huge image and mask only the region that the subdivision represents), but I dont know the performance costs of masking or if this will create other problems.So is there anyway to split up a movieclip of vector graphics into smaller movieclips of vector graphics the same way copyPixels can with bitmaps?

View 1 RepliesIt is known that a display Object removed from the display list will be garbage collected only if any event listener associated with it is removed.What I would like to know, but could not anywhere find an answer to, is that for a class that we create which extends, say Sprite, and uses and manipulates various other display elements within it, while removing an instance of this class from the display list is it sufficient to remove the event listeners associated with the instance of the class, or do we necessarily have to remove all internal event listeners of the class definition associated with the display objects that the class uses and manages.

View 2 RepliesI understand that Objects not referenced by anything are garbage collected, and have been making sure to null out referenced to objects when I'm done with them. What I want to know are a few things:Do only Objects need to be null-referenced?How often does garbage collection usually run? Does it tend to run when processor demand is low? Is there a way I can tell garbage collection to run manually, such as when I'm done with a playing field full of sprites? This is not really needed if garbage collection tends to run when processor use is low, since it will run anyway at the times I'd like it to.Objects created just for the scope of an if or for statement etc, unless they are assigned a reference elseware, are eligible for garbage collection, right?

I am creating a bunch of movieclips when I first start the flash movie.I then put them into an array and use functions to add and remove them by selecting a random index in the array.When they are removed are they marked for garbage collection?Or can I just keep creating them.Might be hard to understand so code is below
var mc1:mov1 = new mov1();
var mc2:mov2 = mov2();
var mc3:mov3 = mov3();
var mc4:mov4 = mov4();
var theRandomClip:Number;
var movieClipArray = new Array(mc1,mc2,mc3,mc4)
function getRandom():void{
theRandomClip = Math.floor(Math.random()*movieClipArray.length);
addChild(movieClipArray[theRandomClip]);
}
function remove():void{
removeChild(theRandomClip);
}
//Then I would call them in succesion many times
getRandom();
remove();
getRandom();
remove();
//etc do I need to worry about them getting garbage collected and no
//longer being available?
Hope that makes sense
No matter what I do I cannot solve a tween AS3 Garbage Collection problem I am having that is wreaking havoc on my tween instances working correctly/consistently. Some Sprites never tween at all, some do but only part way. And it effects different ones almost each time.
I have read a fair amount recently on AS3 Garbage Collection and improperly referenced Tweens and other asynchronous instances getting picked up in mid process. I am experiencing the signature inconsistent behaviour that the I have read of.
I have tried using class level Static and non static properties to store references to my Tween instances so they will not be marked for GC. No luck. I have placed references to them in Class level Arrays, I have also used TweenMax's static to() Method that insures that it will shield it from GC and its alt. non Static
constructor instantiation, with persist:true. I also implemented another custom package; GCSafeTween(), other users said it does as it should, but it's not working in my case.
To test the GC problem, I edited the two eventListerners() in the Adobes' fl.transitions.Tween so that their default weakReference property was false. Doing this made the Tween work correctly. But that's a terrible solution.
