Flash :: Task Management, Threads And Other Foes In Builder?
May 31, 2011
I'm building a simple task manager that will at this moment execute tasks in a serial manner. I have been reading about threads in flex and it seems it is not quite clear/prepared for real threads.
What I'm looking at this moment is a way to execute a method at the beginning or end of a flash builder update. This method will be the one that will take the responsibility to start tasks added in the previous update. The removing of finished tasks will be done through event notification (the task will notify it finished) then the scheduler will remove it and dispatch the message again to let the outside world know the task was over.
I've tried using the haltonfailure="false" and failureproperty="compile.failed" but ant just throws an error when I try to run it: "The <mxmlc> type doesn't support the "haltonfailure" attribute." I need to do a little cleanup before the build script exits if the mxmlc task fails, how do I achieve this?
Has anyone noticed the following behavior building Flex programs using the mxmlc ANT task (running in the background): as the MXMLC task starts, it steals the window focus from whatever application is currently running, and then gives it back again! This is extremely disruptive.Is there a way to run the MXMLC task "headless" so it doesn't interact at all with the window system?I'm running on Mac OS X (10.5.8, if that matters), and Flash 4.0.1 (although the behavior existed on 3.x as well).
I have a flash movie loaded into my browser.Is there any way that i can pause it and then resume it.I tryed SuspendThread() for all the browser threads but the movie won't freeze
I double-clicked on a bitmap-item in the library and instead of opening the properties-windows where you can change compression, import and so on, the focus changed to a random explorer window and flash got "locked". Flash probably thought that it actually opened a new sub-window and waited for it being closed, but there was no such window! Seems like the open-procedure failed and the next window to focus on was just an explorer window. Closing this one didn't get the focus back to flash. What a luck, I could still save the file using ctrl-s but couldn't get back to the application. So I had to kill Flash with the task-manager.
My AS 3 program has multiple buttons. Users can select one and then immediately select another and this causes 2 threads that collide. Once one button is executing, I want the other buttons to ignore clicks.
The problems are twofold: 1) the first time the 2nd button attempts to execute (by checking lock), when it returns (from checking lock) and attempts to pick up processing where it left off, it seems to forget where it was and does not utlimately complete its task(s); possibly variables have been altered, it is difficult to say. That is, AS 3 is unable to successfully pickup where it left off on the first button. the second problem is that AS 3 incorrectly returns to button 2 after the lock condition is cleared. It persists and will execute that button.
I create myself a key like it shows in the video tutorial on youtube. I then turn my developer_identity into a .pem I then try to export it into a p12 and I get an error saying that my key doesn't have a password. Why does this keep happening and what can I do to solve it? I created a p12 on a mac, but it won't work when I try to use it on a PC.
Does anyone know if there is a way to make the new Package Explorer window in Flash Builder emulate Flex Builders 'Flex navigator' window?
Bottom line is I don't always need to peer into SWC's, and I don't like having a 'default package' automatically created for me. Not sure why the interface wasn't made simpler, allowing access to more power and complexity only if necessary. I want to focus on the code, not on how to navigate and use the bells and whistles in the coding environment.
I am able to disable mouse events on a movie clip with a single frame using the mouseEnable property and setting it to false.However if the movie clip contains multiple frames setting the property to false does not disable the mouse events.Do I need to disable for each frame of the clip? Or is this outside the box for movie clips.I have tried .enable and .mouseChildren to false also.I have alternatives to what I am trying to do so I am trying to determine if I am missing something.this is basically my code, this code will ignore events if I change the movie clip to a single frame.The multiple frame movie clip is made up of 5 frames of bitmap symbols and functions properly.
public class Main extends MovieClip { private var contract1:MovieClip=new CONTRACT ;//multiple frame mc public function Main() {
I have an AIR project that I was working on Flash Builder 4.5 which now I'm trying to import to my updated Flash Builder 4.5.1 and it is prompting me to fix some paths before the import is completed. I'm kinda clueless what I should put in those fields.

The project access a web server to retrieve data using JSON.
I'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).
I am struggling to find clear guidance on how to switch on colour management in Flash CS4. My attempts to search online have tended to give me far too many irrelevent results and it is not even mentioned in the index of my 700 page Flash CS4 textbook.
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

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.
Is there a best way to put a content management system into a Flash website so (very IT illiterate) people can update text on certain pages? Im expecting a simple notepad document that they can FTP to a specific folder is the best way but I didnt want to give them access to the entire site.
Does anyone have suggestions for a good method to manage the display list in an actionscript 3 project? I'm building an application at the moment and keeping track of all the modules which need to be displayed and reordering them has become unwieldy.I have loaded swfs and instantiated classes that also load in swfs, images and video.. Should I just reference everything to the stage? How should I keep track of the display tree? How can I always force one particular module to the top of the tree?
I am planning to build a giant management system in Flex 4.0, and I just wanted to know what are some pros and cons of using 4.0 (or 4.2) over 3.5? Lighter components? Faster pipelines? What are some things I can look forward to when using Flex 4.0?
This blog (and others) state that you should set object references to null inside your dispose() methods when cleaning up objects. However, Actionscript 3 (with Flash Player 9) uses mark and sweep to clear out circular references for you. So I am wondering: is there really any reason to null out your object references?
I have a meeting with a potential client this upcoming Wed. If I am hired, I will be redesigning his website, the major components he wants are galleries of his sculpture art and a way to update the images himself.
My idea: develop a custom CMS so he or his secretary can easily update what images are in the online flash galleries. My idea right now is an HTML/PHP form where they would enter what gallery the image goes to and maybe an upload button for the image, they hit submit and the PHP form edits an XML document which is where the gallery gets its image info from. Can anyone help me figure out how to do this? Or if there is an easier way to develop a CMS for them to update the images in the gallery themselves? Being able to remove images via a custom CMS would be ideal.
I'm working with FLash+XML, and I had a thought: I don't want to give my clients Flash+XML solutions, if they will have to edit the XML themselves. It's too complicated for them.So I thought of a Flash Application for offline use, that would be some sort of a XML Content Management System, built in flash, suitable for offline use (user should upload updated .XML files which is OK). In this app, creating / editing / removing nodes should be like managing folders and their content in Windows Explorer.I don't believe my mind is bright enough to be the first having this idea, perhaps such program already exists. Does it?

I don't believe my mind is bright enough to be the first having this idea, perhaps such program already exists. Does it? If not, please enlighten me: which kind of function allows me to "write to XML file, offline"?
I am trying to migrate a project from Flash Builder 4.0 to Flash Builder 4.5. After Flash Builder prompts me to choose my new SDK, I choose 4.5, Then I get the following error:" error "The required skin state 'disabledWithPrompt' is missing".
I'm new to actionscript so I can't create task that I need.My problem is that, I can't change the task doing every frame with actionscript.let me example:
In this code I told flash to move the object (instance_name) 2 pixels to the right every frame. and if it arrives at the end of stage, It move 2 pixels to the left every frame. But when I test the movie, at the end of stage it wouldn't turn back and move to the left and stood still. Its because it process ( instance_name.x += 2; ) after it got out of the end of stage.
im developing a web based project management web site using phpi need charts for tasksabout the gant chart it is ok i found a javascript library which functions can take the tasks names , dates and durations then draw a gant chart.but my problem is about network diagram for the tasks , i need javascripts libraries or flash action script can make thi
Flex Builder 3 provides support to generate actionscipt from WSDL via the GUI ( Data->Import Web Service (WSDL) ) - but this sort of method requires that you check in the generated source. This is not desirable to us (we understand both sides of the 'should generated source be checked in' and we have decided that they should not) so we would like a method to generate the actionscript classes from an ant task. In this case, the WSDL would live in the file system.
Using the Flex ant task to build our application results in the "Flex Data Visualization Trial" watermark being displayed in our charts. We have professional licenses for flex builder but do not know how to tell the ant task about these.
I have some code that I want to wait until the first step of the process is done and then do the next task. But I can't seem to think of a way to do it??The full code for the entire process is this:[code]How would I tell it to wait until the first part is done to perform the second part?
