I just wanted to check something if anyone can clarify this:
If I create an object with
Code:
And then replace it by doing
Code:
Does the original instance get deleted or will it remain in memory? If it does, how do I remove it properly?
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?
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:
class MyClass {
public function myMethod():String {
return "some return value";

I use the Flash IDE to create Sprites and MCs really quickly, but is it better to create assets at run time using the graphics funcitons or to just instantiate things from the library?
View 2 Repliesanyone actually successfully implement 3D object instancing with papervision 3d?and does it actually perform good enough to be used to instancing many copies of a single model (tress for example)?so far I failed to correctly display the instances and I doubt the performance benefit of doing this as papervision 3d is using software render.
View 1 Repliesin my main I have a system that allowed certain classes to be loaded and unloaded. When I load Game.as, it contains a trace statement when you press the left arrow key. When I remove the game instance from the stage, and set it to null, I can still press left arrow key, and the trace will come up. If I then make a new instance of game, it traces twice with only 1 click. When I close/load another time it traces three times.
I very specifically set:
Code:
mainContent.removeChild(game);
game = null;
Even trace statements confirmed that the game was being nullified, and the trace still continued.

View 2 RepliesI have a simple movie that just runs to the end and stops. When it stops, I want an object to appear and remain visible while the movie is sitting there in its stopped state. Trivial. My current model of the Flash stage is that if you drop an object onto the stage, it's there for the whole movie and it's up to you to move or hide it to get what you want. (That is, you can't add an object to the last frame of the movie, at least without bringing ActionScript into play.)
So, as far as I can tell, the only way get what I want is to add the object to the stage, make it into a button, and use alpha control to hide the object/button until the last frame of the movie, when the alpha goes from 0 to 100. This works, but I'm filled with the feeling of "this has to be overkill". I'd have the same feeling if I started the movie with the object off-stage and moved it on-stage in the last frame. Is there a more reasonable / lighter weight way to do this?
I am trying to get a stationary object to follow the mouse but remain in its location. Example: i am trying to get the center of a compass to follow the mouse around screen while remaining inside the compass. i have only found out how to have it chase the mouse but not remain on a fixed point and rotate.

View 7 RepliesDoes creating a new instance of an Object that uses an identical name to an older instance, delete the previous instance? Or should the original instance be deleted first? The code uses a ridiculous amount of XML vars. Isn't it less memory intensive to parse the XML and save the properties to an Object, and then delete the XML Object, rather than keep the XML Object around and reference it's child nodes directly? Is it better form to break up a huge XML file (>600lines/3200vars) into smaller chunks?
View 1 RepliesI'm trying to create a quick access to a object with a String as it's key, so I wrote:
"var map:Object = {};
map["key1"] = object1;

Is there any difference about the performance between long key and short key(the length of the String used as a key)? If the key contains many charactors, will it slow down when accessing that object?
Was at a site the other day that used a shared oject to tell me how long I had been viewing the page. I left the page, came back and the counter restarted right where it was when I left. This is cool, but what if there are say 30 people viewing the same page at the same time? As I can't write the code "myObject = new sharedObject" to get a new instance of the shared object, how is this done? Or, when I use the "get local (remote) sharedObject" does that give me a new instance of the shared object? Or is there only ever 1 instance of a shared object?
The reason I ask is say I'm writing a multipalyer game, and I want to store user information in a shared object so it displays in everyones swf. Well If I have only 2 people playing the game, fine, that's 2 shared objects. But what if there are 100 people playing the game? Or am I looking at the shared object use all wrong in the first place? I only have a small pea sized man brain so the logic escapes me...
I am loading an SWF file into another parent SWF. I remove the loaded SWF using the unloadAndStop() method and set the loader to null. But the instance of the loaded SWF still remains there in the memory.
View 2 RepliesI 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?

View 7 RepliesI have a question regarding AS3 memory management. Supposing I created an instance variable for a Class, in this case or type Sound:
public class SoundStore extends Sprite{
var s:Sound;
Then within various class functions I referenced this variable multiple times, each time I wanted to load in a new sound:
s = new Sound();
Am I correct in thinking that each time I created a new Sound I would be overwriting the previous allocated memory?
I am wrapping my brain around OOP in AS2. I am making two posts on two different subjects. My question here is: when should I use local instance variables, and when should I attach new properties to the instance object? (Feel free to correct my terminology.) Let's say I have a class for a scrolling background, which scrolls when I mouse over its edge. I want to put these values somewhere:
1) How wide is the border in which a mouseOver makes it scroll? This is basically a semi-constant I set it up once and keep it the same, unless the user changes it in an options menu to make the border wider or narrower. Call this scrollBorderWidth.
2) How fast is the background scrolling now? I want to track this so I can smoothly change the scroll speed over several frames. This is often changed. Call this scrollSpeed.
It seems I have two ways I can store and access these values and darned if I know which is better practice. METHOD A: Make them local variables in the class, so the scrolling background instance has them as local vars. I set them up thusly:

var win:TitleWindow = PopUpManager.createPopUp(this, TitleWindow, false) as TitleWindow;

It does indeed place the chart in the titlewindow that shows up, but it removes the original chart from the parent. Then, when the titlewindow is closed, my chart is simply gone. I can't figure out how to clone the chart -- all the methods I've tried failed
