If my class has declared a private var _iDontGetDefined:EnormousObject; but never creates anything to be stored there, does this impact performance or use a significant amount of memory?
View 1 RepliesI'm trying to set up a menu. Because this menu can have a varying number of entries, I'm generating it instead of hard-coding it. The Menu object contains an Array of MenuEntry objects, and each MenuEntry has a framework.Button object which contains the text and box that actually gets drawn to the screen. I can add a MouseEvent.Click event to the Button, but not the MenuEntry. If I do it that way, though, I'm unable to access the data in the MenuEntry object that contains the button, so I don't know which MenuEntry was clicked.
The only solution I can think of involves checking the mouse position against the position of each MenuEntry, depending on the number of Menu Entries. This does not seem like the right way to do it, though, as it is not scalable. I tried having the MenuEntry class extend the Button class, so theoretically, the MenuEntry itself could dispatch mouse click events, but that didn't work.
I was thinking about how to streamline my code the other day and looked through my classes checking for possible memory leaks. I wonder when are variables declared inside of methods clear for garbage collection? or are they not and just hang around? For instance if I have a class like this:
[Code]...
Since the variable was declared without reference into the class how long does it stay in Flash's memory, or does it stay indefinitely because it cannot be nullified?
I'm having trouble wrapping my head around creating an array as a data member of a movieclip, i.e. dynamically adding it to that movieclip depending on data brought in at runtime.
Would I have to create an array seperately first and then somehow assign it to a new (typeless) data member of the movieclip?
Scene 1, Layer 'auto button', Frame 1.The instance name 'semisideview' is declared on an object of type flash.display.SimpleButton but there is a conflicting use of the instance name 'semisideview' on an object of type flash.display.MovieClip.
View 1 Replies"you cannot delete variables that are declared within a function with the var statement".Which, as it happens, is precisely what I was trying to doI want to delete the object because it holds a bunch variables that are no longer needed, to prevent potential speed/memory issues later on.it's impossible (probably with reason) and I know vars are local to a function, so now I'm wondering if it is actually necessary to remove local variables

I'm getting a run-time error: Error #1009: Cannot access a property of method of a null object reference referring to the for loop's first line dataWriteToDB.PeopleName since it is NULL. I'm guessing the problem here is that while dataWriteToDB is declared initially, the array lengths for the arrays in PeopleInfo class have not been set yet. Or, not sure otherwise why it's NULL.
I am trying to access a shared object declared in a certain function, from another function. I am having

I am creating an object pool to cache some recyclable objects in memory at the outset of my application in order to avoid (as much as possible) the performance issues caused by GC running; if possible I'd like to minimize the memory my object pool reserves, so I'm attempting to pool generic forms of the objects (with no methods) and then casting the generic variants to more specific and complex object types which extend the generic form when I actually want them on the stage.
The trouble is that to do this requires the generic variant class to import/extend MovieClip (because the more complicated objects are themselves MovieClips and make use of DisplayObject methods)-- does simply importing and/or extending a class add to the memory an object takes up when instantiated even if it never uses methods from the inherited class? It makes sense that it would, and some light profiling seems to suggest that it does, but I'm not 100% certain. About how large should an 'empty' MovieClip instance be in bytes?
what I have is:
- listener added with weak refference, therefore it shouldn't keep the GC away
- object set to null
- trace of the object m shows null
- debugger shows the value of m as null
But the "frame" trace still keeps on appearing, so where exactly is that object and how to check for it, how to delete it and kill it. I know that listeners keep objects in the memory, but then how to find them, and at the end of the day also used weakReference=true while assigning it, so that should take care of it. What exactly is going on here?
When debugging, I see an objects memory reference next to its value. Is it possible to get that as a string or assign a variable based off memory location?
var myInt:int = 5; debugger shows(@afff222)
var copy:int = memor(@afff222);
I have this line
Code:
this.parent.removeChild(this);
So basicaly the object is removing it self from the parent object,but I still think that it exisits in memory and doing its backend job.How can I remove it completely from memory?
I am getting problem of memory of having repeating object. Below is my code.
import flash.system.System;
var counter:Number=0;
var systemMemory:TextField=new TextField();
systemMemory.x=200;
stage.addEventListener(Event.ENTER_FRAME,showNext);
function showNext(event:Event){
[Code] .....
Above code does repeat textField Object continuously. Now I want to destroy previous created textField Object. So that my memory will not be hang. I got some where in the blog that with System.gc() could clear garbage collection. But currently I am not working with system.gc any more I want to clear previous object in programatically way. Is there any way that I could destroy previous created object?
There are a number of posts on here about merging XML with Java, but I can't seem to find any reference to Actionscript for the same task. I have a group of XML files that I need to load. I want them to sort into one XML Object in memory. For example, let's say these were my XML files:

I've been trying to figure out how Flash does its memory management regarding object declarations but haven't found anything that describes declarations themselves. [code]Basically I want a pool of declared variables that get instantiated only when a certain type is set. I'd have logic in other functions that figures out what the type is and then does certain things to it, but for now I just wanted to know what kind of memory management Flash does with something like this. Does it do nothing until I actually instantiate it (= new Object()) or will space be set aside once I simply declare it (someObj:Object)?
View 2 RepliesIs it possible to delete a LoadVars object from memory, as well as its contents? Say I load 20k of data into a LoadVars, and I delete the LoadVars Object, does it stop loading variables into memory, and does it delete the memory that it importing?

for a periodic table tool I'm making, I've incorporated an effect that changes the alpha value whenever I hover over an element (pretty standard). I've noticed a mysterious gain in memory when hovering over my elements; using SYSTEM.TOTAL_MEMORY - there would be about 0.005MB increase in memory usage when I hover over an element, which isn't relinquished when I move my mouse off. However, if I move my mouse back on again, there isn't a second memory gain.
[Code]...
Does anyone know why this memory gain is happening when the alpha value is changed? And curiously why it only happens once? Some extra info: my Element class is a MovieClip, with a couple of TextFields, primitive variables and a MovieClip in it. It has had its mouseChildren property set to false (and buttonMode property set to true).
This might be a dumb question. I think I already know the answer, just clarify. If you declare a object in varible1 and then pass the value into varible2. If you decide to null varible2 would that kill just the reference or the object itself as well. I want to say no, but then again, everything you do to the reference it self, also affects the space in memory.these are the 2 varibles in my class.
private var objects:Array;
private var viewableObjects:Array;
above are class varibles. Later on in my code I add an object to the objects arrayobjects[0][4] = new Enemy1();When i trace i get the following[object Enemy1]I then add it to viewable objects arrayviewableObjects.push(objects[0])
This has been a long-standing curiosity of mine, and I haven't gotten around to profiling to find out, and haven't seen it asked yet (for AS3):Let's say that I have a class:

I am trying to traverse object tree in AFL (adobe flash lite) engine, to check if there are memory leaks in an event driven application (AS3). The idea is to get object tree dump before and after an event processing and check the object tree dump difference for memory leaks.I believe MMgc is the GC for AFL, I am unable to get a dump of object tree, can anyone help me to point out where in code I can get the alive object info in tamarin.
View 1 RepliesI have been trawling around forums for hours now and the only was to save information LOCALLY in Flash seems to be using the SharedObject stuff. which is fine. BUT I am making a project which is meant to be entirely run from a memory stick i.e. portable. So, I was thinking it would be good to save the information from the flash to a SharedObject .sol file and then to copy the .sol file to the memory stick, then load the information back into the flash file from the copy of the .sol file on the memory stick!
Dont know if this is possible, but I need to some how save information created in the flash file stored on a memory stick (which will be text and possibly an image which would be loaded from the users pc) to a file on the memory stick and then next time the flash file is run, load all of the information back in!
I know all this stuff is possibly using PHP etc. but as I am running it from a memory stick on a pc which probable wont have internet access.
Anyone know if there's a way to check for objects in memory that have been removed from a display object but not set to null?
View 1 RepliesIf an asset (say an swf) is already loaded. Does it increase memory use to add and object to the display list?
View 4 Replieshow do we remove object( sprite which has an external swf as it's child ) from display and more importantly from memory yet we still can use the same variable to add another object (yes another sprite like the one we removed yet has different content).., "
i did tried the removeChildAt thing it did remove all the child from the display list but i still can hear sound from video running.
here is small scale code of what i'm doing (sorry that i can only give you chunk code of loading and adding)
// var SWFList:XMLList; //used to hold a list of all external swf source,atribute and etc// var totalSWF:int; //hold the total number of external swf there is to be loaded
// var swfLoader:Loader; //instance of loader class used to load the external swf

I have an FPS monitor running and notice that I am getting choppiness here and there, bringing my game from 40 to 27 fps and back and forth at certain stages. I have an idea of where it is happening, but do not know for sure. I looked up quite a few memory monitors but haven't found anything decent yet. Is there a memory monitor that allows you to see the memory leaked and find its location? If not, how about just he memory leaked?
