I'm kind of messy and I ussually change the class linkage name a lot .
What happens with unused anymore linkage classes ? Are they automatically deleted by flash CS3 IDE ?
Edit:Long time no answer What I mean is not if they are still available (haven't tested but probably aren't) , what I mean is will those linkage classes be compiled into swf increasing the size or not ?
I'm developing an AS3 application which has some memory leaks I can't find, so I'd like to ask some newbie questions about memory management.Imagine I have a class named BaseClass, and some classes that extend this one, such as ClassA, ClassB, etc.I declare a variable:
myBaseClass:BaseClass = new ClassA();
After a while, I use it to instantiate a new object:
myBaseClass = new ClassB(); some time after
myBaseClass = new ClassC();
and the same thing keeps happening every x millis, triggered by a timer.Is there any memory problem here? Are the unused instances correctly deleted by the garbage collector?
I have just started my first project using AS3.0 and Flash 9 this week.I feel like I know AS3.0 from my flex experience very well, but it is downscaled for Flash 9. Anyway I have looked for this issue in the forums and maybe I am just missing something.I have a class we'll call MyClass which extends Sprite. I have several methods in there that update things like rotation and position based on events it is listening for via the model. I even have a trace statement in the constructor for testing.
Now maybe this is just stupidly obvious but when ever I set a library element to link with the class (i.e. linkage = MyClass), all my script fails to work. If I remove that linkage and work from a purely data perspective it works as expected.I have the project settings to Flash 9 and AS3.0 so that shouldn't be an issue.
I am starting to create classes instead of using the timeline and I am learning a lot more even if mistakes happen more often. However I have a question about linkage & library. For example let say that I have a ball pic called Ball1.mpg. I copy and past that Ball1.mpg in my folder where the Fla file is as well as the as file. If I want to utilize this Ball1.mpg in my code using Flash do I absolutely need to import into my library and link it and export using linkage? Or can I use the object Ball.1mpg just using actionscript. Of course that implies that I would use an actionscript class not the timeline.
View 1 RepliesIn my project I have to classes that inherit the MovieClip class. Then I create a movie clip and in the library I click on linkage and I set on AS2 class field the name of the first class. Inside this movie a create another movie clip and I set his AS2 class to the second class. The problem is, when I run the file the properties of the nested movie clip are not available for the parent. What a mean is that in the constructor of the first class I cannot acces the methods of the nested movie clip. Somehow I need the nested movie clip to be initialized first and then the parent.
View 1 RepliesFlex complains if I want to create an object from a library symbol with linkage: 1180: Call to a possibly undefined method [linkage name]. So to avoid this, I create a class for that symbol, in this case extending BitmapData using Flex's new ActionScript Class feature. Flex create that class for me and the constructor looks like this: public function CustomBitmapData(width:int, height:int, transparent:Boolean=true, fillColor:uint=null)

I'm trying to create a linkage to swap movie clip dynamically. I already create a linkage and after my movie clip symbol actuall say Export: contact_idea. But when I try to attachMovie("contact_idea"). It does nothing. Is there anyway that I can test that the linkage is actuall linked?
View 2 RepliesIs there any way to auto-import as3 classes (internal/intrinsic Flash Player classes at least) using Emacs ?
Looked for as3-mode and actionscript-mode but nothing working was found. as3-mode can import class if it is opened in buffer (but not *.mxml files)
The examples I'll use don't do anything - they're classes without ANY members - no variables, methods, anything.
Let's say I extends Sprite and call it MySprite.
I save it in test.core
[code]...
Now I create another custom class called MyWindow that extends MySprite.
I save it in test.windows
[code]...
Then I create another class that extends MyWindows (the example I'll use is a document class - but that doesn't matter - I've tested using an instance too).
[code]...
Notice that I'm not even trying to instantiate the helper classes - just having them there throws the error.
If there is only a single helper class, everything runs fine.
Also note that - as far as I can tell - this only happens when extending one class from another package, then extending that class with more than one helper object.I'm pretty sure there's no namespace bumps or typographical errors, as this is a very pared-down version of the original application.
EDIT: seems the problem exists even without the crossing packages - even extending MySprite in the document class with multiple internal classes generates this error.
I am creating a library in AS3. Inside the library I make use of a bunch of classes/packages that need not be exposed to the end user of my lib. I want to only expose one of these classes.
I guess my questions are:
1) How are libraries commonly distributed in AS3?
2) Is there a .jar equivalent in AS3 that developers can include, but will only have access/knowledge of the classes I've declared as public?
I have an actionscript project which uses visual symbols from an SWC. I have a CheckoutButton which has the following class associated with it (compiled into the SWC in Flash CS3).

I previously asked about some FLV files that I was loading externally, and having trouble with memory being released. Having sort of solved this, I am having the same problem with loading external resources and then getting them to be cleared out of memory when I'm done with them. I have seen kglad mention more than once that GC in flash 9.0.124.0 is broken, but where does that leave us? I have also tried my project in FP 10, and the memory still continues to go up and up. If I load an external resource - in this case I have a class that builds a VR room with papervision - and then close it, set it's instance to null, my memory never goes down.
This is a total guess, but could it have anything to do with using Tweener in my project? Is there any way that the Tweener class could be keeping some of my objects in memory and keep them from being GC'd? I am using weak references in my listeners, setting any variable I can find to null... I can get over how frustrating this is to just see memory go up and up but find no reason. The class I am using also uses a few subclasses to build itself, but I end up with one instance of my VR on the stage. If I have set that instance to a name - myVR - and then removeChild(myVR) from the stage and set the name to null - that should do it right? Boy, this is frustrating.

View 3 RepliesI've recently created a game in which the logic and programming all runs perfectly, however the graphics are lackluster. I'm currently having a hard time managing the depth of movieclips on the screen.Basically the game is tile based and each frame of the movieclip holds a different type of tile. All the tiles are 50x50 with the exception of one type of tile which is 60x60 and therein needs to overlap the tiles around it which are 50x50.In AS2 I could of set the depth manually, however I'm told (as is this is my first time dealing with depth in AS3) that I cannot do this anymore. Is there any suggestions on how I can make sure that a tile of one type is automatically set beneath tiles of another type - I've thought about simply coding a function to check this but it somehow seems inefficient (considering larger maps will have a lot of tiles, meaning hundreds of movieclips attached to the stage, each movieclip with multiple frames).
View 2 RepliesDoes flash supply 'invisible' containers, to make object management a little easier ? eg. add some objects to the container, then add the container to the stage, then later on remove the container (i.e removing also the objects) ?

View 11 RepliesI started with some AS2 pageflip code that I've been modifying because I needed the code in AS3, and I wanted to make some changes to it. At anyrate, I'm having a problem with the depth of two movieclips created. The code first creates a page using the makePage function, and then creates a shade for that page (makeShade function).When running the code, the page appears on top of the shade. When using getChildIndex, the page's index = 11, and the shade's index = 14.
The complete code is super long so I've attached the code that has the shade and page below:
//create left-aligned page-sized solid fill
function makePage(targ, xQuadrant) {
//trace ("in make page");

I have done a lot of searching / reading to find out how to clear my memory. But I still can't really work out how to clear the memory, it just never seems to come down. I have a few MovieClips that contain other MovieClips with pngs inside them being added to the stage.
As fare as I can tell all Event listeners are removed and refrences I remove the clip, with removeChild I "null" the variable I am using the "LocalConnection()" hack to try and force a clean up, but no movement on the memory count. Are there any examples of a *.png being added and removed from the memory?

View 16 RepliesI need some advice integrating our content management system with FMS. We are currently using Oracle's Universal Content Management 10g and FMS 3.5.
I am able to get the test video to stream by creating a VOD streaming application in Flash (drag/drop FLVPlayback component and setting the content path to rtmp://serveraddress/vod/TestVideo). However, when I try to incorporate it into UCM the video doesn't load. I have tried checking the .swf skin, .swf video, AC_RunActiveContent .js file, and even the .html file (I have edited the .html file to reflect the new path for the uploaded .swf and .js files) and I still get nothing. I suspect that the .swf video file that creates the connection to the FMS server has something encoded into it that can't be called correctly once it's uploaded to UCM. If this was a traditional website where I could simply drag and drop the files generated by flash into the site's hierarchy, there would be no problem.
I have a NetStream set up and it's supposed to listen for DRMAuthenticateEvent.DRM_Authenticate. When I give it an encrypted file (encrypted using software from drm-x.com), no DRMAuthenticateEvenet seems to be dispatched. The code looks like this:

I have both proxy and drm authentication types in there because drm was not working for me so I decided to try proxy. Am I doing something wrong? I got this stuff off of the Adobe reference pages, is there an easier/smarter way of going about DRM in Flex?
I was recently profiling my application that uses Degrafa States in the skins and noticed that doing so uses more memory than I expected. Between the SetProperty and State, they were using about 10% of the total used application memory.
Would it be better to use css for the state changes and a new skin for each state? or Are there some simple tips to reducing the memory footprint of degrafa?
Ok, I'm using Jquery to build a dynamic menu, and sIFR to change the text to TrajanPro font.
This does not mix. I want to find a way to make it mix, though.
sIFR has automatic parsing of links, so that Flash sends you to the link location. What it doesn't do is pass on javascript triggers. I'm trying to make my menu as accessible as possible, by using hard links and then rewriting them with Jquery into managing the visibility of submenus, like this ~
[Code]...
the Flash Virtual Machine relies on garbage collection by using reference counting and mark and sweep (for good coverage of these topics, check out Grant Skinner's article and presentation). And yes, Flash also provides the "delete" operator, which can (unfortunately only) be used to remove the properties of dynamic objects.
What I want to know is how to make it so that Flash programs don't continue to consume CPU and memory while running in the background (save loading content or communicating remotely, for example). The motivation for this question comes in part from Apple's ban on cross compiled applications (in its SDK 4) on the grounds that they do not behave as predicted with the multitasking feature central to iPhone OS 4. My intention is not only to make Flash programs that will 'pass muster' as far as multitasking in iPhone OS 4, but also to simply make better (behaving) Flash programs.
Put another way, how might a Flash application mimic the multitasking feature of iPhone OS 4? Does the Flash API provide the means for a developer to put their applications to 'sleep' while other programs run, and then to 'awaken' them just as quickly?
In our own program, we might do something as crude as detecting when the user has been idle (no mouse motion or key press) for (say) four seconds:
var idle_id:uint = setInterval(4000, pause_program);
var current_movie_clip:MovieClip;
var current_frame:uint;
[code]....
what's the best way to detect that an application should be shelved? And, more importantly, is it possible for Flash Player to detect that some of its running programs are idle, and to similarly shelve them until the user performs an action to resume them?
I'm building an Adobe AIR application (2d platformer adventure game), utilizing the Flash Builder 4 IDE, which will be packaged on a CD for installation. I've embed the majority of the game assets into a static class to keep it simple and organized. This way I can reuse assets and swap them without much digging.
Example:
[Embed(source = "../data/gfx/spritesheets/boyHero.png")] public static var boyHero:Class;
In the early days of the projects, everything went to plan. However as the project has grown to be over 28MB, I've started to run into Out Of Memory errors. These occur when I add new assets, refactor for a while, or add new classes. Once I get this error, I can restart FB and then work for another 15-20 minutes. I've modified my .ini file bump up Flash Builder 4's memory allocation. It's currently set at:
-Xms512m
-Xmx1024m
While I'm at it, here are the specs/plug-ins that I've got installed:
Flash Builder v 4.0 (build 272416)
JNA Library 3.2.7
subclipse plugin 1.6.17
subversion client adapter 1.6.12
subversion JavaHL Native Lib 1.6.15
SVNKit lib 1.3.5.7406
Mac OSx v 10.6.7
2.53 GHz Intel Core 2 Duo

My Questions:
1) Is the issue with the path that I've chosen for the way I'm handling in-game assets? I am streaming in some assets such as tutorial swfs which are loaded via the SWFLoader. I could go this route for all assets... but, should I? Is this the right way to handle a disk game? (The game runs without a hitch when installed on QA machines...)
2) Provided the embedding of static assets isn't an issue, Is this a FB4 bug? Where should I head for more information?
I am a flex programmer but i had nothing to do for handle manage memory in my projects. I think lack of memory management is reason for loading lag of swf file. Can any one help me to how to handle manage memory in flex/ as3 codes.

View 1 RepliesI'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 RepliesI have a section on a site that my client wants the ability to add her own links within. So basically she wants the ability to content manage that section of the SWF.
I know how to do this using XML but I'm not comfortable presenting it that way to my client. Is their a clean and easy-to-use way for my client to add her own links into the SWF? She has no HTML experience so that's why I'm hoping there's a simple way to allow her to do this. Is it possible to build an HTML page that has 2 input fields and a submit button. The first input field would be for the link name and the second would be for the link path. Then submitting that data would update the SWF file? (I'm sure that I'm over simplying this but I thought I would throw that out there)
