Lets say a scene started off around 70-80mb, it loaded a swf in, and by removing the event listener and setting objects to null and numbers to 0 before unloading the swf,and went back to the original scene, the memory stack up till like 80mb++, and every time I repeats the same process the memory goes up higher,is that normal? or its a memory leaking issue?
View 4 RepliesI have ship game that i create using falsh as3. but i have the problem with memory usage. the memory usage still increase when game played. whereas the System.gc was called, but the memory still increase.
View 1 RepliesI 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
Here's my question. Suppose I've written some AS3 code like:
statementOne;
statementTwo;
Is there any possibility that the garbage collector will run during or between my two statements, or does it only run after my "user" code has finished and returned control up to flash? We have an A-Star codeblock that's sometimes slow, and I'd like to eliminate the GC as a potential culprit. The codeblock is obviously more complex than my example above, but it doesn't involve any events or other asynchronous stuff.
fully removing objects from memory, but I still think I'm not getting it. I've written a test script that looks the following:The stage has is of class MemTest
Code:
package
{
import flash.display.*
import flash.events.*
[code]...
There is approximately a 3x difference in the rate of gain of memory usage between simply letting the movieclips accumulate or running removeChildforever() in the enterframe. There doesn't seem to be a difference between using the "killme = null;" line or not.However, I am still seeing an constant rate of increase in memory usage of about 3 megs over the course of a minute, running at 120 fps. why is the memory usage still going up? Is garbage collector run so infrequently that it hasn't happened after 7200 frames?
Looks like the garbage collector is not removing movieclips that have textfields set to TLF. I'm using Flash Builder's profile inspector and TLF brings in a bunch of objects and prevents the clip from being removed by the garbage collector (including all the objects that TLF put in memory). How could Adobe release CS5 with such a crappy implementation of text? If there is no solution I will have to avoid using TLF text for all my projects.
View 11 RepliesI've coded a 2000 line game on one actions layer (facepalm*) and I just recently learned about the GC (garbage collector). I've looked around a bit and can't, how to trace the source of it. There is an interesting article that mentioned event listeners and for every addEventListener there should be a removeEventListener. My game has 60 adds and only 15. What I can't make sense is that the mc's that have the event listeners are never removed, but just moved off of the stage. Others are just made invisible. So if the event listener is added once, why would the memory keep growing? (I'm using the Windows Task Manager to monitor this). Another point was to remove objects so that the GC can do its work. What I did was create an object, add it to an array then null it.
_object1 = new _barrel();
_object1.x = objectPosition;
_object1.y = _defaultFloorBoundary.y;
instanceArray[objectNumber] = _object1;
_object1 = null;
Then removed the object from the array.
for ( var ii:int = 0; ii<instanceArray.length - 1; ii++ ) {
stage.removeChild(instanceArray[ii]);
delete(instanceArray[ii]);
instanceArray[ii] = null;
}
take a look at the following code
var a = new View();
a = null;
....
class View {
[Code]...
will a be in memory after a = null? Does addEventListener adds a strong refernce?
I'm forgetting now exactly how I should dispose of unneeded objects. In the past, every object/class I created had a public dispose() function which removes all added listeners inside it and called the kill/dispose function on any children of it that may need the same (so it worked its way down the tree, as this process can continue for as many children/grandchildren there are in the list). So basically, the code in the parent class would look like this:
Code:
childObj.removeEventListener(MouseEvent.MOUSE_DOWN, anotherHandler);
childObj.dispose();
childObj = null;
...and the childObj class would look like this:
[Code] .....
Do I need to set any variables/objects defined in the child class's class scope to null prior to setting the class itself to null? Or is this handled automatically when I set the class itself to null from the parent (assuming these class-scope-defined variables/objects have no listeners or child objects which need to be disposed themselves)?
I'm trying to export a Flash movie as a .mov file. The animation is not that big but there are strange display issues. As the character moves across the screen, there are bits and pieces left on the screen from the previous movements. It's just not rendering correctly and looks terrible. I can't seem to fix it and have been playing with the Format settings etc. There's always the junk left on the screen.
View 2 RepliesI've decided to move on to AS3 (and maybe AS4 in the future). I've done PHP object oriented programming and Java oriented as well, but Flash is a bit different because of actual visual things that occur.
I tried to follow a very simple tutorial. I made a "collector" MovieClip and added both the identifier "collector" and the class "collector" to it. I added the project class as "superClass".
In superClass.as I had the following lines of code:
ActionScript Code:
package {
import flash.display.MovieClip;
import flash.display.Sprite;
[Code]....
is to an undefined method. I don't really see how this could be, since I have the collector class.
I have a stage that's filled with dynamically generated isometric objects [ in the shape of a smiley, placed according to an array ], and when i click a button, i would like the stage to be cleared, then another frame with another isometric code and another array to load.The problem i am facing now is that the items positionned from the smiley are still on the stage if the next array is smaller than the previous one.Currenlty, i triedunloadMovieNum(depth) in between with this code:
Code:
n = 50;
onEnterFrame = function(){
[code].....
I've created a map with the 50 states. I then hardcoded this so that when you hover over them the alpha is set to .5, and if you click on when it's ChildIndex is set to -1 and it plays the animation of the state growing to full size. I know there is a better way to do this, rather than how I wrote each line of code for each of the fifty states...
I'm also trying to play an outro animation "down" after the state is clicked while it is enlarged from the "up" animation.I also tried to create a var state so that when you mouse off of a state the state is no longer highlighted, but I ended up doing a work around using currentframe=.
Code:
//import flash.events.MouseEvent;
var small:int = 1;
var big:int = 2;[code]....
if you have object inside of object inside of object ... etcwhen you want to completely remove it is it enough to just say:removeChild(topObject);or you need to go inside and start cleaning from there?
View 3 RepliesI'm trying to clean up my code for an animation I created. I'm hoping by doing this, my animation will stop being as buggy and/or I can more easily figure out why its being buggy. think that variables are the way to go so I read up on them and have a decent idea of what I need to do. But what sounds good in my head doesn't seem to work on screen.So basically I would like to take my three buttons called card1, card2 and card3 and combine their functions. All the code for each button looks exactly like the code below (except for the mc name of course)
Code:
card1.addEventListener(MouseEvent.ROLL_OVER, overhandler);
function overhandler(event:MouseEvent):void {
[code]....
The reason why I'm writting it's because I'm doing a website in Flash, and I don't know how to do one thing.I can create the TextArea, it's ok by now. But what I want to do now it's create 2 buttons. In the first, the "Clean" button, if I clicked on him, the TextArea delete everything it was written there, and in the "Send" button I send an e-mail to one e-mail, with what was written in the TextArea.

I had Flash 8 on my computer, and back when CS3 came out I purchased the full suite and installed that. Yesterday (years later, now) I was cleaning up installs on my computer to free space. I used Control Panel to remove Flash 8 from my PC.Now Flash CS3 still launches and works, but I cannot get .swf files to launch on their own at all. When I double-click them to open them, I get the message:
The file does not have a program associated with it for performing this action. Create an association in the Folder Options control panel. I've googled to figure out what that means or how to do it, but I haven't found a decent reply that's been effective. If I try to drag a .swf into a browser window (or just open it with a browser), it is also not recognized. Oddly enough, I can view Flash files on web pages no problem (when browsing online)...
Some necessary components must have been removed when Flash 8 was installed. I suppose I could try re-installing Flash CS3, but the problem with that is that I'm out of town on business for the next 10 days. My Studio install discs are back at home, and I need to get work done this week!.
I have an array that when traced, lets say looks like
Code:
Carrot,Apple,Strawberry,,,Cantaloupe
I'm just wondering, what's the best way to tell if an element in an array is empty?
I'm a relatively experienced programmer, but I'm completely new to as3my question is how can I remove one object and subsequently all it's child objects and their listeners?I need to remove all objects from a certain object called "world". My objects are all on top of this "world" object. the game has a level object which is on top of this "world" object and it produces enemies among other things on an enter frame event.To remove this from the stage I call the world.destroy() method from the main timeline.
Code:
// * Destroy the world
public function destroy()
[code].....
As a best practice should trace statements be removed form all AS once we're on the final files? Or does it not matter and therefore best for future reference to leave them be?

The problem I am facing now is that the items positioned from the smiley are still on the stage if the next array is smaller than the previous one.

Code:

if ( n<=0){
nextFrame();

What happens is that it clears the stage, but doesn't load anything in the following frame.
I have a bit of code that calls a custom class that I made in flash. Basically when you roll over this logo I have a function that makes a new instance of a custom class and calls it to the stage like a little pop-up text when you roll over something. Then when you roll off of it I remove it from the stage. The following code is for the first pop-up text.

I have made a game that after you reached a certain object it will switch to the next level. The next level is in a new layer and in a new frame. Problem is I think all of the properties (speed, collions etc..) have been inherited... Meaning my charachter will move on his own and collisions will still apply for objects if the previus frame.
Is there some kind of way to clean all of the properties and have "fresh" start? I have tried to clean the Array that detects the collisions, the collisions work now. But the player now is 2x faster and also jumps 2x higher... I don't have the code to past in here right know, I will add it later. So, summing up. Is there some kind of way for me to clean the properties of objects from one frame to the other?
I'm trying to do a cleaning of some classes that is added into a MovieClip, but I can't seems to set the MovieClip(Class) to null. What is the proper way to do it?

It 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.
