ActionScript 3.0 :: Sockets: Every Event Detector Is Running In A Different Thread?
May 30, 2010
I know that the thread concept (as a class) does not exist in as3, but I don't understand very well the internal execution when I'm sending/receiving data via sockects.timer.addEventListener(TimerEvent.TIMER, endData);socket.addEventListener(ProgressEvent.SOCKET_DATA, receiveData);(The former event detector is just for sending data every X ms. The second one is activated when I receive something from the socket.)Then, the question is: "sendData" is executing in a different thread that "receiveData"?

it seems that Flash was supposed to run in a sandbox in the browser. But, if Flash can get data from a remote server, can it similarly get data from localhost IP on the same machine? In other words, can I use a Windows app that provides a TCP socket on localhost to feed data into a Flash app?the answer is yes at least for the case of an SWF file hosted in the file system, URL...(turns out the localhost access error can be fixed if you add the SWF app to some security whitelist). Still wondering if this can also be done for SWF apps hosted on the network.

Has there been any word on when the output progress event is being implemented? At the moment flash sockets are useless at uploading anything other than basic text files or maybe images because we are unable to control the amount of data being sent. The way I see the output working at the moment is when trying to send large files, the input buffer becomes flooded and in the process of trying to transmit so much data at the same time, many packets are lost. I tested this by trying to transfer a 570mb AVI to an ftp server. By the time it got there the file was only 37mb. The event would allow us to calculate the network speed of the system doing the uploading and the speed of the server doing the downloading so that the buffer size and intervals can be optimized.

Often i would like to wait for an event to fire before continuing my code. I hate to have to create tons of functions to fire one after the other in a sequence when it makes much more sense for all the code to be in one function.
So instead of myFunct1() to fire myFunct1_part2 which fires myFunct1_part3, i would like to have all the code of all the functions in myFunct1().
The reason i can't do this is that i continuously need some values that aren't set until an event is fired. This is an example:
ActionScript Code:
var xml:XML;
xmlhandler = new XMLHandler();
xmlhandler.addEventListener("xmlLoaded", function() { xml = xmlhandler.xmldata; });
xmlhandler.loadXML(path);

I start an eventListener on frame 73. If I stop my movie and test animations in the flash player (going back to frame 1 for instance), the movie starts throwing errors because the listener is basically trying to listen on an object that doesn't exist anymore. So I was wondering if I could try somekind of "try {stage.removeEventListener(Event.ENTER_FRAME, myfunction}". I tried that with a catch statement but of course "try {}" doesn't work with asynchronous events. How would I go about that?

I have a BUNCH of bumpers of four types bounceUp, bounceDown, bounceLeft, bounceRight. during a collision which you hit determines the bounce so they always do the same thing so here's my question.....can i just name every bounceUp instance the same thing and then just add that one instance name to the list the collision detector checks?
i just dont wanna go through and name a hundred each of bounceUp s and bounceDown s individually as the potential for screaming increases proportionally.......

While we have a dedicated AS3 forum, we know that a lot of Flex 2 users will cross back and forth across forums because while Flex's core scripting is MXML, it fully supports AS3 as well so it's confusing sometimes what forum to post in and who is best suited to offer help. A lot of topics have been covered in the last 6-8 months at a lot of the more well known guru sites and popular blogs and as we get going we will link up anything that might be of use to users in here.Url...

In a flash movie, I'd like a user to be able to have a choice of buttons, each of which would add a movie clip. (E.g. If they click button "A" it will add a barking dog, if they click button "B" it will add a running cat, etc.)
I then want the user to be able to e-mail this movie with a PHP form (which I know how to do) but in the URL string, it will load the movie (dog/cat) that the user has selected. That way, when their friend receives the e-mail, it will take them to a page with the flash movie that shows the movieclip their friend chose.

I understand the Flash and AS3 is single-threaded, at least at the user level. I would like to understand how asynchronous data loading is handled by the Flash player.
For instance, if I run CPU-intensive code that runs beyond the normal frame (lets say it runs on ENTER_FRAME, and consumes 1/4 per call). Does this leave any CPU cycles to load data from a URLLoader?
If http loading is truly synchronous, right down to handling the TCP/IP stack, one would get horrible performance. In Windows programming, I can do http access asynchronously (in which case the Windows libraries are doing either input on a separate thread, or doing hardware-level interrupts to handle the data -- I provide an asynchronous callback that may be on its own thread). Or, I can do synchronous download, in which case there will be hardware buffering, but my application is actively waiting for each buffer of data to be delivered by the hardware/OS combination.
URLLoader is asynchronous, but what does that mean? Does it mean that I can run the CPU and still download data? Or, will my download speed slow to a crawl if my Flash application is under heavy CPU load? Understanding how this works will help me design my product better, which both uses a lot of CPU, and downloads a lot of data (to the bandwidth limit of the network, if possible).

I am aware that Action Script does not provide multithreading so when writing flex application we are limited to work on one thread. which is ok for rendering my UI.
However some questions arise when preferring flex over silverlight:
As a UI layer single thread is good enough but is it fair to assume that for Aync httpservice like operations in flex , internally it would use some worker threads to manage the async operation and then come back to the main thread ? it looks like it does since my UI does not freeze.Can the flex/flash player deal with multiple httpservice calls in parallel ? ( e.g more than one section of the UI loading data at the same time.)How about the animation stuff ( e.g the parallel animation ) - does flash player internally leverages some threading for accelerating graphics or is it all done on the UI thread ?

So within my Flash document I have a rollover movieclip that contains a UI scrollbar. My question is, can I modify this rollover script to be active until it reachs a certain frame in the animation and then become inactive so that the scrollbar works? Or, is there some script that I can use to make the UI scrollbar active within the rollover clip?

I have a Delphi 6 Pro program with a TWebBrowser component that loads a web page that embeds a Cool Iris Wall. The Cool Iris wall is an SWF object which means that when running, the execution happens inside the Adobe Flash player, an ActiveX or similar object I believe. The problem I am having is that sometimes when the Wall is loading pictures/videos from the web, it takes a big hit on the CPU on the main UI thread. I know that TWebBrowser moves most of its operations on to a background thread to keep the main UI thread happy, but something the Adobe Flash Player is doing is happening on the main UI thread and its causing my program much grief. Is there a way to move the Adobe Flash Player on to a background thread?
[UPDATE - 12/7/2010] - After a marathon probing and debugging session it turns out that the problem had to do with the Cool Iris Wall's Flickr proxy. You can interface with the Wall in two main ways: 1) You pass them special Flickr api protocol URLs and let them talk to Flickr for you, for example [URL]..loads the Wall with the results of a Flickr keyword search for puppy. The advantage to this approach is that they do all the work for you necessary to make the query to Flickr and build the Wall's contents. 2) You build an RSS media feed yourself containing the photo stream item data and feed it to the Wall.
I was using technique #1. The problem is with #1 is that when their servers have trouble building the Flickr feed for you (for whatever unknown reason), their host SWF puts a heavy load on the CPU interfering with the main UI thread's operation. I converted my entire code base to work directly with the Flickr API and create the feed myself using the second technique and the problem vanished.

I am writing a simple Tcp server in Unity and have my Flash application connects to it.I found a great tutorial on threaded Tcp server online, and my flash app connects to it nicely. However, I am not able to send data outside of the listening thread to the connected client. I tried to create a global reference of the Tcpclient obtained inside of the thread. However, that reference (sclient) only works inside of the listening thread, printed Null to console outside of the thread. There must be something I can do to retain the TCP client reference for later use or access it from outside of block thread.

I'm beginner in Flex 4. I'm trying to pop up a Flex WindowTitle custom component, and after the user choose some values, the parent window must be refreshed.I'm showing the modal window, the user can't interact with other components, but the problem I detect is the execution of the program flows, even I choosing to show the Input window as modal, the next methods to refresh the page is called before the user close the modal page. I don't know if flex or ActionScript works different from Java, where I used to code. see the comments on the code example:
