I would like to send and receive OpenSoundControl in an AIR application, on the opensoundcontrol.org website I have found existing libraries for many languages, but none for Action Script so far, do you know of one that could be readily used?
Tuio AS3 has nice classes for OSC. Check this example http://bubblebird.at/tuioflash/guides/sending-osc/

I'm looking for a pub/sub messaging system to connect various applications I'm building, some of them will be iOS, other ones AIR/AS3 and maybe some openFrameworks.
I found out Faye and it looks like really interesting. I've found libraries to integrate it in all my apps/languages, so I'm trying it out.
Now, the problems are with the AS3 implementation. I've found this great library and it's kind of working, BUT I've some issues I can't understand. My main problem is that I can build clients, connect them to a node.js server and exchange information between them, but after a while they stop receiving information.
So I was wondering:
do anyone of you have experience with Faye and this library, and knows if this behaviour it's normal and if there's a way to prevent it? I've done some tests using some html browser clients and everything was ok, so it's definitely a flash library problem
do you know any other library to implement Faye in AS3/AIR? I was browsing a lot but I couldn't find anyone
Do you know any alternative pub/sub messaging system I could implement (easily) in as3?
Thank you
We've open sourced our implementation of AS3 Faye client recently. You can find it here.
It's been in prod for more than a year and was tested by millions of users, without issues so far. It's used in Flash Player Web and AIR Mobile applications.
Interfaces mimic JS client interfaces, so its setup is as easy as JS client setup. Plus one additional feature: multiple urls for reconnection fallbacks.
Give it a try!
I am starting with my first application development. So far I have worked only with Html, css, js, jquery etc..
I want to create an app like the desktop gmail notifier which pings the server at regular interval, look for any messages and notifies the user. I read that Adobe Air and flex are the tools that can be used for this. I have developed the basic prototype in adobe air by studying the tutorials in net.
But the problem is that, my client doesn't want the source code to be made available to users. With air, you can see the complete source code after installation/unzipping the .air app.
Is there any way I can protect the source code? Or should I use flex and convert it to a swf? Is the source codes are protected in flex? I am not familiar with the flash action scripting. Please advice.
I think you are confused as to what Flex is. It is an SDK that is a level below the AIR and Flash SDKs. Flex is a secondary structural language that is meant to be used in conjunction with AS3, while AIR is compile-type.
It doesn't matter how you compile this, the source code will be attainable if someone really wants to get it. If you compile as an AIR app, you can unzip and get the SWF file. If you compile as a SWF, you already have that SWF. The SWF can then be decompiled using various tools.
There is no real way to hide front end code from prying eyes. Flash is definitely harder to read than HTML or CSS or Javascript, but definitely not impossible to view regardless of how you compile. Your best bet is definitely to offload as much as possible to a server and possibly obfuscate your code.
I would definitely try to explain to your client that it is simply not possible to truly hide source code from individuals who would like to access it. If someone really wants to steal the code, they can and will.
Code cannot be hided in any front end technologies, Flash (SWF, Flex or AIR) or HTML (JavaScript).
Do all the business logic at server and authentic properly for securing your data.
And AIR and Flash Player are both runtimes which play applications written in Adobe Flash or Apache Flex.
You can use a client-server implementation to hide the logic from the user and flex would just render a UI based on the business logic from the server side code(php,java or .NET) that interacts with the gmail servers
If you want proper notifications, go with AIR - access to some system-level features like toast notifications. With Flex, you'll be limited to webpage content.
About code protection - you can develop app in ActionScript and then protect compiled SWF with obfuscator for some fair defense, although there's probably no good free obfuscators. I paid some bucks for secureSWF license and consider it a good investment. Of course, determined hacker would crack app anyway (in theory,) but I would'nt worry about this too much for a simple pinger app.
I would like to play a flash animation when someone talks in the VoIP program Ventrilo.
I have a simple animation setup within Adobe Flash and I would like to somehow trigger it when a specific person talks "keys-up" in Ventrilo.
I know the G15 keyboard can access Ventrilo remotely and display who is talking in real time so I think it should be possible to use this event to trigger a movie clip play command if I knew how to access it. I have looked for example code but can't find any.
I know this is probably a highly complex task but I'm sure there is a genius on Stackoverflow how knows how to do it or could at least set me on the right path.
Many thanks,
This is not going to be an easy task and is going to require writing a C/C++ ANE.
You can use Windows API hooking to intercept calls from Ventrilo.

You would need to write an ANE to use this inside your AIR app.

Is there any way to use the library of other language in Action Script 3 ?
For C/C++
I learned that we can use Alchemy: http://labs.adobe.com/technologies/alchemy/
But for other languages (here I mean Ruby or Java), can I use their libs via AS3 ?
Alchemy is a cross-compiler from LLVM to ABC, if the language you are interested in can compile to LLVM, then, in theory, you can compile to ABC. So, Alchemy supports (with some tweaks) also C# or Java (but you will have to spend some time getting them to work together, there's no out of the box solution).
AIR (which is a desktop variant of Flash) can use something called "NativeProcess" which means that granted the operating system can execute the code in the library, then you can do so by creating a new process that calls the function from the library you need.
In AIR, again, there's a new feature called ANE (AIR Native Extensions) - this allows you to bind AIR more tightly to the native code. But, it doesn't need to be native as in object files only, it should be something the underlying system can execute. But I have to confess, I never tried creating any such extension, so my knowledge of it is theoretical.
No you can not use Ruby or Java code/libraries in Flash. Alchemy only allows you to use C and C++ libraries. The only way is to port those libraries to ActionScript, or maybe the library you want to use has already been ported to AS3.
It is also possible that there is something similar in AS3. You could ask another question here or on an Flash forum if anyone knows if the library you need has an equivalent in flash.
I have got an assignment in which I have to implement a AS3 wrapper for any FLV player and I have to expose actionscript functions (External Interfaces?) so that other can be used in other different applications via CallFunction API. I have few questions regarding this -
Are the tools for this are freely available? I know Flex SDK is but I want standalone swf (I means Flash Player 10) that can be used anywhere without any dependency and should contain FLV player embedded or should be able to load it from a particular location by supplying the URL.
Is it possible only with an ActionScript compiler (or any free tools?). My problem is that I don't have flash or flex builder and I don't want to spend money on these because I don't work on it.
As I have almost zero knowledge about it. Can you guys please explain me (if possible with details) that what I need to do. Any resoures on how to create and compile?
If any of you have ever done this it would be really great if you guys can share samples. I've heard that many people have done the same thing for video players.
I can share a bit of my setup
I use Flash (CS5) for creating assets
I use FlexSDK as the compiler
And do all the code in FlashDevelop
Flashdevelop is for PC only for now, it's free and comes since the last few versions now with a debugger
I use FlexSDK to compile and Eclipse with AS IDE or something along those lines, and then preview things in a web browser using an html page with the swf file embedded.
check out projectsprouts. its a pretty nice Flash (as2/3/Flex/AIR) generation tool that can help you stub out your project, compile it, and even create unit tests if you want. pretty simple ruby install (i am a ruby newb, and got is running pretty easily). It was a pretty good support base, and an active mailing list where people will be happy to help you along.
It is important to note that the FlexSDK has very little to do with Flex unless you are linking against classes that are Flex specific. mxmlc does not have anything to do with MXML even though it will also compile MXML.
Here is an article that describes Flash development on Linux. It is pretty old, but the principles are the same. With an Actionscript 3 Compiler (contained in the FlexSDK) and a text editor, you are off to the races. It is a lot easier with Flash Builder 4, FDT 4, Intellij IDEA, Flash Develop, etc ;)
