ActionScript 2.0 :: Garbage Cleanup - OnEnterFrame, Intervals, ?
May 23, 2007
A project I'm working on is working just fine at first, but as I perform more actions, it slows down noticeably. I've made sure to clear any onEnterFrame and setInterval events, so I don't think the problem lies there. Most likely, it's because practically every time an action occurs, much of the content on the screen is redrawn/recreated. However, every time I create a movie clip, text field, shapes, etc., I call a function to remove it beforehand:
Code:
function killThis(mc:MovieClip, thingsName:String):Void{
var obj:Object = mc[thingsName];
if (obj instanceof MovieClip){[code]..........

onEnterFrame=null, onEnterFrame=undefined & delete onEnterFrame....
Which one to use??? What are the performance considerations. If all my movieclips on-stage are running a MovieClip.prototype.onEnterFrame = function() {run initial stuff before setting onEnterFrame=null/undefined... }, will there be performance hits? It's sad that delete onEnterFrame doesn't work unless I delete the prototype enterFrame as well, which would make the clips reinitailise itself again once you declare the enterFrame prototype again (i need to do this since there's more movieclips that end up appearing on-stage, and they need to automatically initialises themselves the moment they appear).

panning my content from left to right (with stop as intervals) then right to left (also with intervals)
1. I created an mc (name: "content")Notice in this mc, I layout 4 sets of text (like a page) from left to right
2. I created another mc (name: "pancontent_mc")
-I added a layer for "content" and created a motion tween for it to pan from left to right
-I created a mask layer on top of "content" that will show 1 set at a time
-I created an action layer that has total of 4 stops(); on each frame where the 4 sets of text will show directly under the mask.
3. maintimeline -There's only 1 layer. I placed an instance of buttons (left/right) and an instance of "pancontent_mc"
4. actions for right button, works fine and stops on each set of text.
on (release) {
this.pancontent.play();
}
5. actions for left button - none. I havent figured this out yet.
on (release) {
this.pancontent. - something like play previous frame until stop...
}

I figure that this code can be reduced with a for statement, but I can't figure it out. Here is my code, and below that is my attempt.On the stage I have 6 movieclips named nav1_ani, nav2_ani, etc. I also have 6 buttons above them named nav1, nav2, nav3, etc.Here is my code, here I got #5 and #6 working. Instead of duplicating all this code, is there a way to bunch it all into one "for" statement?
Code:
nav1on = false;
nav2on = false;

If I call the play() function of a Sound, which returns a SoundChannel object, will the SoundChannel still linger around after the sound clip is finished playing and eat up resources? Or will Flash's garbage collection scoop it up?

I create some elements( UIComponents, mainly Panels) inside the "mx:Application name=tst . I need to cleanup all those UIComponent's on MouseClick event , using Actionscript. Is there any way I access the children elements of mx:Application ( I used var totalChildren:Number = this['tst'].numChildren ; but looks like it fails to access the children list).

I have a simple AIR app that listens on a socket using the SocketServer class.I have the following code when I first start up the app:
if( serverSocket.bound )
{
serverSocket.close();[code]....
However I find that if I try to test my movie after making some quick changes, I can't bind to the same address:port. I'm guessing that somehow that the port is still occupied. I get a "Operation attempted on invalid socket" error.But if I wait a bit and then test my movie, I can bind to the address:port. The close() is not taking affect. Can I try to close() this when the user decides to exit the app? Is there some sort of event that allows me to do something before the app quits?

Generally when you unload an swf from another swf you would follow a cleanup utilzing removed from stage or unload events. But when you exit an as3 flash application by either navigating away from page or reloading the page or closing/removing the application. what is the best practices you would follow to ensure proper cleanup and garbage collection.
Question : what methods in solely as3 code can be used in this regard. It may be argued that once an swf is unloaded or removed its memory foot print can be verified to have decreased eg via the task manager Is this a good enough measure? Or is it advisable to handle the unloading/exiting in a proper manner ?

[URL] I needed to do clean up before the MC is gone ... so after some digging I found this event:
Event.REMOVED_FROM_STAGE
So I am trying to ask for some conformation here: Is this the ONLY situation that my MC will be deleted automatically by Flash? If so then I can just listen to this even and call my cleanup function when it happens...

I have a Flex client application. I need a clean up function to run in Flex when the user closes the browser. I found the following solution on the net, but it only works half-way for me. How could I fix it?CustomEvent triggered, but not executed. >> EventHandler for CustomEvent.SEND_EVENTS is defined by a Mate EventMap. All the handler does is to call an HTTPServiceInvoker. In debug console, I'm able to see the handler and HTTPServiceInvoker being triggered, but neither the resultHandlers nor the faultHandlers were called. I know this event handler has no problem because when I dispatch the same CustomEvent.SEND_EVENTS in a button click handler, it behaves exactly as I expected)Browser seems to wait for cleanUp function to complete before it closes. (all traces were printed before browser closes down)
Code
I added the following into the index.template.html
window.onbeforeunload = clean_up;

I've got one function that I'm running, but I need it to run at different times for different movie clips.Here's my code. What is wrong with this?
ActionScript Code:
function tweenText(_TEXT:MovieClip, _START:Number, _END:Number, _SEC:Number, _INTERVAL:Number) {
var xTween:Tween = new Tween(_TEXT, "_x", Strong.easeOut, _START, _END, _SEC, true);
clearInterval(_INTERVAL);

I'd like to change a timer interval, In my code I first initialize the timer with a selected interval with :
Code:
gameTimer=new Timer(interval,0);
gameTimer.addEventListener(TimerEvent.TIMER, IALoop);
gameTimer.start();
Then, I need afterwards to change the interval, so I try to stop the timer, remove the listener
Code:
gameTimer.stop();
gameTimer.removeEventListener(TimerEvent.TIMER, IALoop);
And when I init again the timer with the same code:
Code:
gameTimer=new Timer(interval,0);
gameTimer.addEventListener(TimerEvent.TIMER, IALoop);
gameTimer.start();
It's like if i had 2 timers, and when i stop the timer, it continues, I guess it's because of the new object that I create, but I can't found a method to change the interval of the existing timer..

i 'd like to know if there is a way to clear all Intervals in a movie with one command.in my current project I use setInterval()very often in different clips and though i cleanly put the corresponding clearInterval() commands in the script I realized, that on slow computers some of them don't get stopped.Which puts more weight on the CPU and sometimes slows down the comp very much.

Right Now I have the banner counting down but how do I get it to count in different intervals?
Right now I have an interval setIt = setInterval(this, "counter", 8000);

I just started learning Flash as part of a project, consisting of a spider-like figure which is supposed to vibrate every 20 seconds. I've basically got the vibrating to work but am having more trouble learning about getting it to vibrate at different intervals. I was hoping that someone here could point me in the right direction as to where to find this information, even an applicable tutorial or something.

I am working on a Flash Video player and am implementing the ability to start a video at x time within the span of an FLV (served from FMS). I am able to start it x seconds into a stream without any issue using
netStream.play(source, startTime);
but as far as I can tell, it only supports seconds. I am looking to be able to give a start time (or even a seek time if that is supported) in milliseconds, or really anything more precise than whole seconds.
Anyone know of any way to achieve this even by monkey patching the fl classes?

I have a Flex chart and on the x-axis want to be able to have different intervals set so I can draw gridlines.For example the axis may be from 0 to 82 and I would want to have an interval at 6,8, 21, 29, 40, 49, 52, 59 and 70.

I have three Flash movies (all the same pixel size) that I want to use on the home page of my website which is built in MX 2004.
How often the movie changes is not critical, but I think once an hour will be fine. What's the best way to get Flash to automatically change the movie every hour and where should I attach any code - to an Actions layer in movie no. 1?
As a summary, here's what I want to achieve;
12.00pm - movie no. 1 plays
1.00pm - movie no. 2 plays
2.00pm - movie no. 3 plays
3.00pm - movie no. 1 plays again
...and so on for 24 hours until you get back to 12.00pm when movie no. 1 plays again.

I was wondering, is there a way to change if (myClip_mc._x < 400) { to a relative position of myClip_mc. I mean, i want myClip_mc to move 100px from it's current position everytime the button is clicked. Instead of only moving it if it's x position is less than 400. So it needs to somehow check it's current position everytime the button is clicked and then make it shift from that position. I know this is a long winded way of doing it but i want it this way so i can use it for something different.

Its seems a problem I am having is to do with setIntervals in a while loop. I clear what seems to be the interval but as another interval is started before the last one finish I then have multiple intervals. I can close them all down with this...
for (i= checkImage;i>0;i--){
trace("clearInterval(checkImage) " +i);
clearInterval(i);}
But that ofcourse closes the rest down before they have done what I need.
I think my while loop needs to change? Here is the current while loop code....
function loadImages(){
while (imageWidthList[leftPictureNumber+imagesDisplayed] > 0 and xPosition +(imageWidthList[leftPictureNumber+imagesDisplayed]+(borderThickness*3)) < 700) {
var img_mcl:MovieClipLoader = new MovieClipLoader();
linkLayer = this.createEmptyMovieClip("link"+(leftPictureNumbe r+imagesDisplayed), _root.getNextHighestDepth());
[Code] .....
Is there a way that straight after the setInterval and the loadClip the function watchMyImageLoad is run to completion before continuing in the while loop. What I have seen is that the while loop continues until the condition has been met and then all the intervals are run?

There are a few fairly intensive procedures the class goes through, which require me to stagger out the action taking place. That is to say, if I were to use recursion, there are times when I'd easily hit a stack overflow, so to compensate I'm avoiding recursion through recording information in class level variables and running through the routine again (and again and again) on an ENTER_FRAME event.
This all works great, and I'm happy with the result. The only annoying bit is that performance is better when the frame rate's higher (and slower when it's lower). Run the class at 30fps, and the time it takes to complete is significantly slower than at 120fps. No surprise there, but still annoying since I'm not interested in making the user make changes in their framerate to accomodate the class.
So I considered switching to a timer-based method, but then I remembered something about the Timer class accomodating the framerate of the SWF. Looking it up confirmed what I remembered:
...if a SWF file is set to play at 10 frames per second [fps], which is 100 millisecond intervals, but your timer is set to fire an event at 80 milliseconds, Flash Player will fire the event close to the 100 millisecond interval.
Now I'm wondering if it's even worth the effort, since it would appear that the end result would be much the same as it is now using enter frame.

I have an swf loaded in a browswer (fire fox) and i use log on console using [code]I have initialized my swf in the document class on the Event.Added to stage.and i have a clean up function performing all the clean up/exit process in the code on the event [code]Now Doubt that this is being called/ activated/trigered as i am not able to log the start and end of the function to the console.The console log is of firebug.What exactly am i missing here? I would like to call the cleanup function on reload of page or relode of swf or change of page.How do i trigger and log it properly
