ActionScript 3.0 :: TweenLite CPU Optimization - Just Stacking And Never Garbage Collecting?
May 12, 2011
I'm currently working on a game where every "Step" - defined by a global time modifier - everything on screen calculates where it's next position will be, then uses tweenlite to animate itself to that location. This program runs for about 10 seconds before it eats 100% of my CPU. iMac i5 quad core, so it's not the hardware.
The problem is specifically in the following snippet, and the peculiar thing is if I teleport everything to it's next position (i.e. don't tween it there) the CPU is stable at 6% (where flash IDE consumes 4%). Does anyone know why these tweens are just stacking and stacking and never garbage collecting? (This is what I assume the problem is, as I can't find another explanation as to why the problem only exists when i TWEEN to the next location)

after strolling through the internet looking for garbage collecting of dynamic movieclips i conceded and justified to myself i should make a forum post.I'm making a small game, with many many explosions. Explosions are random swfs which i cache before using them. Problem is that although i did everything to make them ready for garbage collecting, they seem to overflow the memory.my code:
Code:
package
{
import flash.display.MovieClip;[code]....
the last line, 'e.target.parent=null ', is the way i know how to make movieclips ready for garbage collecting. But if i uncomment the line, I get this error:
Code:
ReferenceError: Error #1074: Illegal write to read-only property parent on example03_fla.MainTimeline.
at Explosions/::doneHandler()
at flash.events::EventDispatcher/
example03_fla is the timeline of the supposed movieclip i'm trying to delete, not the document fla.

I'm trying to get my head around optimising AS3 code and clearing things out for garbage collection.
I understand that each time an item is referred to in the code it has its reference count increased by one, so I was wondering if there is a trace option I can use to see how many references each of my objects has?
I can then see where things are getting left behind (if they are) and where I can make optimise better.
I think it would help me work out several issues if I was able to do this

What's necessary to do when removing an object to make sure there are no memory leaks? Do you have to remove all children? Or just remove all event listeners? Or both?

Its pretty simple what im trying to achieve.I have a MC on Stage, which im trying to tween to different X coordinates.I've set up four TweenLite.to sequences, however for some weird reason only one is being triggered - what am I doing wrong?
TweenLite.to(slider.mc_slider,1,{x:_returnXPos(95), ease:menuEasing});
TweenLite.to(slider.mc_slider,1,{delay: 1, x:_returnXPos(35), ease:menuEasing});
TweenLite.to(slider.mc_slider,1,{delay: 2, x:_returnXPos(50), ease:menuEasing});

I've got to create a form with 2 fields (Name, email adress) that users can type their information into, but i then need to collect the data and store it somewhere (so i would then have a file showing everyone's names and email addresses that have been entered).I have quite a good knowledge of flash front end development but don't know alot about hooking stuff up to xml/php whatever

I want to do something where I collect functions to be invoked later when a certain condition is met. E.g.
function doSomething(someArg:Object):void {
if (conditionIsFalse){
operationsToDoWhenConditionIsTrue.push(function(){
doSomething(someArg);
[Code]...
Basically if doSomething is called twice, I only want operationsToDoWhenConditionIsTrue to hold the most recent invocation. Obviously since the invocations are wrapped in function(){} all the functions are the same. Is there any way I can accomplish what I want?

I want to add tracking to our Flash-based media player so that we can provide analytics that show what sections of videos are being watched (at the moment, we just register a view when a video starts playing)
For example, if a viewer watches the first 30 seconds of a video and then clicks away to something else, we want the data to reflect that. Likewise, if someone watches the first 10 seconds, then scrubs the timeline to the last minute of the video and watches that, we want to register viewing on the parts watched and not the middle section.
My first thought was to collect up the viewing data in the player and send it all to the server at the end of a viewing session. Unfortunately, Flash does not seem to have an event that you can hook into when a viewer clicks away from the page the movie is on (probably a good thing - it would be open to abuse)
So, it looks like we're going to have to make regular requests to the server as the video is playing. This is obviously going to lead to a high volume of requests when there are large numbers of simultaneous viewers.
The simple approach of dumping all these 'heartbeat' events from clients to a database feels like it will quickly become unmanageable so I'm wondering whether I should be taking an approach where viewing sessions are cached in memory and flushed to database when they become inactive (based on a timeout). That way, the data could be stored as time spans rather than individual heartbeats.

i want to finish it in the end! i have this code which generated 20 stars and an ai player collects all of them (going for the one which is closest to it). This code was courtesy of -lauri... the code was
ActionScript Code:
import flash.events.Event;
import flash.display.MovieClip;[code].........
what i have currently is a player who moves around with the arrow keys collecting stars which appear at random moments... i wanted to make it so that the ai can also collect these stars and i am pretty sure that the code for that would be linked to what.

I've made my site with photoshop and all images are in *.*png, saved with transparency and in the same resolution 1000x750. I exported them into my working file in Flash. No problems here.I've started to put each of the images in separate layers and in stacking order I wish, still no problems.Now, I am about in 20th layers I am inserting the image, again in separate layer and what happened? The layer will cover over the layer which is almost at the bottom. Meaning...only the trasparency which is very strange.

I want to load and unload EXTERNAL SWF that contains FLV on mouse click. Loading and unloading the swf is NOT the issue. The problem is how do i get the external swf which contains an flv to stop playing and stacking up on each other.
I can load and unload the swf's as long as I pause the videos before I click on another thumbnail, but if I click on another thumbnail while the external swf is playing it's flv, the previous flv keeps playing and stack up under the newly loaded swf.

The attachment contains two screen shots of a movie clip timeline. The images consist of a text mask symbol sliding diagonally other a text layer, and a picture button sliding to the left under an aqua blue mask. When I scrub the timeline -- things work great. But when I view the movie via the control menu, the dynamic text is not displayed. The images illustrate the masking layers in unlocked and locked mode.
I'm using CS4.

I was trying to make a similar thing with the game SameGame (ie. the block above the removed blocks fall downward). Before trying this with an Array that contains MovieClips, this code worked (tried it with int values). With MovieClips on the array, it seems not working the same way.With int values, example:
popUp(0, 4): Before: 1,2,3,4,5,6,7,8,9,10; After: 1,2,3,4,6,7,8,9,10
But with MovieClips:
popUp(0, 4): Before: 1,2,3,4,5,6,7,8,9,10; After; 1,2,3,4
// Assume the numbers are movieclips XD
Basically, it strips everything else, rather than just the said block >_< Here's the whole method. Basically, two extra arrays juggle the values above the soon-to-be removed value, remove the value, then re-stack it to the original array.
function popUp(col:uint, row:uint)
{
var tempStack:Array = new Array();
var extraStack:Array = new Array();

I'm worried about images stacking on top of each other. The thumbnails are loaded using a for loop through XML, (10 thumbnails). And by using event.target.name when you click on any thumbnail it calls a function (showPicture).

I'm trying to call movieclips from the library to the stage. To do so, I have a list of questions in a list. As a user clicks on the questions, the movieclip associated with it will be placed (at the top of a list) on the stage.This part seems to be working.The problem is that all of the movie clips are being stacked on top of each other instead of actually displaying in a list.[code]

I have a dynamic text box that reads data from an external file using the htmlText and load() functions. My external file contains HTML code for images. I want to have each image displayed next to each other (side by side). Currently, Flash is rendering my images so they are stacking on each other (ontop of each other). I have even tried putting all of my <a> tag on one line, but it is not working.
ActionScript 2 Code from file:
contentData = new LoadVars()
contentData.onLoad = function() {
contentText.htmlText = this.myVariable

In flex, I am using VBox & HBox to stack components. When I try to get x,y coordinate of a component, I always get 0. If I specify cooridnate like mx:VBox x="120", then I get the value.
How can I get the coordinate without explicitly stating it.

Basically I have a little app where a pop up palette contains dragable movie clips that then are placed on the main stage. However when the palette pops up for a second time it remains behind the placed movie clips. The clips have to be on top of the palette initially, but something like on release swapDepths?

I've been following the Changing Stacking Order (swapDepth) tutorial but there's something I'd like to know.In this tutorial, we have 3 buttons inside 3 Mc's. Each Mc is called green, yellow and blue.The AS code for each button is:
Code:
on (press, release, dragOver, dragOut) {
x = 0;
x = x+2;[code]....
What I would like to get is that the MC (window) that I click, goes to the top, BUT respecting the relative position for the others. I mean, in this tutorial, if you run the swf file and put every window a bit one over the other, and click the bottom window, it will come to the top, but the other two won't keep their relative position because the clicked window will be swapped with the one on the top. Understand? (it's very simple although difficult to explain).To make it easier: let's imagine we have 3 papers on the table and I pick up the one in the bottom and put it on top....this is exactly what I want (but in this tutorial, the other 2 papers are moved aswell). I just want that the window I click gets on top of the other 2, nothing else.
According to Kirupa's words, this EXAMPLE here is done using swapdepth aswell, and IT'S EXACTLY the behaviour that I want. Just compare this one with the one in the tutorial and see the different window behaviour.The thing is that I don't know how to do this with "swapdepths". In the AS reference bok it says it can be done but (as usual) they don't tell you how to do it...

I've been working with this file for quite some time now. I have several buttons in this file - for example, general information. From this button (actually mc, using hittest to function as a faux button), another menu springs out. This menu overlaps the button underneath it.
The problem I've been having is that, when the submenu pops out, the user is still able to activate the buttons beneath the submenu (it overlaps the other "main" buttons).
My solution was to "hide" the movieclips that are overlapped by the submenus, like this:

making a flash game that has a lot of rather complex illustrator graphics. In the game you walk down a street, so all the graphics has to be moved every frame. In some levels where there are a lot of objects in the street the game starts to lag. after importing it to flash and making a mc of it, break it apart to save flash from drawing all the shapes that aren visible anyway?

I have a series of mc's that I'm adding to the a display list of "theContainer".
I've set up my code so I can click any mc in that list and make it "selected". I can then, with controls outside "theContainer", change the selected clip's scale or alpha, etc.
I'd like to set up 2 buttons outside that display list so I can change the stacking order of those clips in "theContainer".
So if I add clip "a" to the display list, then add clip "b" to the display list then add "c" and "d" and "e and "f" to it, I want to be able to move any of those clips forward or backward.

I'm producing some animations that have movie clips introduced by a video player cue point handler.The video is on a given layer in the timeline scheme. When one uses addChild(); to introduce a movie clip, is there some way of specifying what layer it should appear on? Otherwise, is there a way of controlling the stacking order of the various components on the stage?

Is there a way to use actionscript to change the stacking order of objects?I run two functions when i start my game, one that adds the player and set it's properties and one that generates the map. The add player function is run last so the player will appear above the map, the problem is that i have some objects on my map that i would like to appear infront of the hero, like certain tree's for example.
Is there a way i can make these objects appear infront by using actionscript? Using different layers won't work as everything is generated dynamically.
