adding a fla file from ported flash project to haxe (openfl) - actionscript-3

What I want is to convert a flash project to an openfl project (which is written in haxe) in order to use its cross platform feature. I used as3hx to convert actionscript classes of a flash project to haxe. Then I fix compile errors by hand, and fix a run time error too. When I compile the project, I see a blank black window, which means that graphics are not loaded. I convert the code and code is working fine, but I don't know what should I do with graphics. There is a fla file in flash project, which I don't know how to convert it to openfl.
Adobe Flash CC, which is the program used to write flash project, does the linkage of a symbol to a actionscript class, and I don't know how to do this in openfl.
In openfl, as far as I know, giving graphics to a class is done like this :
import openfl.display.Bitmap;
import openfl.display.BitmapData;
import openfl.display.Sprite;
import openfl.Assets;
class Main extends Sprite {
public function new () {
super ();
var bd:BitmapData = Assets.getBitmapData("img/openfl.png");
var b:Bitmap = new Bitmap(bd);
addChild(b);
}
}
Where the openfl.png is a graphical file in a special folder named img, which declared to be an assets path.
I use HaxeDevelop IDE.
Thanks for any help

You can't use FLA files inside OpenFL, there's only support for SWF files exported by Flash from those FLA files:
http://www.openfl.org/learn/tutorials/using-swf-assets/
OpenFL's "native" SWF playback functionality is limited but for simple graphics and animations it's usable as long as you figure out what features are actually being supported and limit yourself to those.

Play sound from library by its name in Actionscript3

Is it possible to play a sound from the library by its name and not Class Linkage in actionscript3?? Meaning if I have a sound named "mysound.mp3" in library and does not have a linkage name, can I play it dynamically in my code by any means?? I hope my question is clear.
In general it's not possible, because if you don't use your sound in some timeline it will not even be exported to swf.
If you are using it in timeline (so it's exported to swf) it's possible to extract it in run-time with some third-party libraries/as3 decompilers by parsing raw swf bytes, but I don't advice to go with that way - it's not stable and system resources consuming.
It's much more easy to set linkage, btw why you don't want to do that?
If you want to create an instance of a Class dynamically, you must call it by its AS Linkage. Why proceed in any other way?
How to proceed?
Right-click the sound file in your library and make it available for ActionScript by editing its Linkage properties: select Linkage to open up the linkage window > ActionScript > ActionScript Linkage : MySound (select Export for ActionScript and Export in frame 1). That will export your sound file as an ActionScript Class called MySound.
You can also select Linkage from the Library Panel menu and create or modify your AS Linkage:
So you can create a new instance of your sound Class and play it:
var s:MySound = new MySound();
s.play();

How can IntelliJ and Flash symbol library work together?

If I'm using IntelliJ Idea as my IDE for code that's being used by an fla that I'm compiling with Flash, is there a way I can tell IntelliJ what objects exist in the symbol that I'm writing a class file for so it doesn't treat references to these objects as undefined?
Example:
I have a Flash project in Flash CS5 with a MovieClip in the library which is linked to MyClass, an external class file. The MovieClip has a TextField named myTextField.
When I edit the class file in IntelliJ, it complains about references to myTextField because it has no way of knowing about it.
Is there a way to clue in IntelliJ? Can I just declare myTextField in the class file, or will that interfere with the instance that's already in the MovieClip?
You need to set your FLA publish settings to allow you to declare your instances in your class files. Try this:
http://www.wastedpotential.com/flash-as3-stop-using-automatically-declare-stage-instances/
If you follow these steps, you can declare your instances as properties in your classes. Your FLA will compile and IntelliJ will stop choking on them.

How to store and use a native executable in a SWC with AIR?

I am developing an AIR application. This application needs some hardware accesses that are not possible with AIR. I decided to use the NativeApplication class in AIR, which launches a C# executable. The AIR application and the "native" application then communicate with the standard output and standard input streams.
A bit like that:
private var np:NativeProcess = new NativeProcess();
private var npi:NativeProcessStartupInfo = new NativeProcessStartupInfo();
private var args:Vector.<String> = new Vector.<String>();
private function creationCompleteHandler(event:FlexEvent):void {
args.push("myCommand");
args.push("myParameter");
npi.arguments = args;
npi.executable = File.applicationDirectory.resolvePath("MyNativeExe.exe");
np.addEventListener(ProgressEvent.STANDARD_OUTPUT_DATA, onData);
np.start(npi);
}
private function onData(e:ProgressEvent):void {
while(np.standardOutput.bytesAvailable != 0) {
trace(String.fromCharCode(np.standardOutput.readByte()));
}
}
I put MyNativeExe.exe file in the application directory, set the "extendedDesktop" value in the *-app.xml supportedProfiles, and it works fine.
Now, I would like to create a kind of AS3 SWC library that embeds MyNativeExe.exe and which provide an AS3 class to manage the interaction with MyNativeExe.exe. Therefore I could easily reuse this work in other AIR projects by simply addind the SWC file as a library. I may have to manually add the "extendedDesktop" value to the new AIR projects, but it is not a problem.
And I am stuck. I can embed an EXE file in a SWC file, by manually selecting the resources to embed with Flash Builder but...
it will not be automatically embeded in the final SWF file as only the needed parts of the SWC file are merged with the SWF
even if it is (enforcing the merge with an [Embed] tag, ...), how can I access and execute the embedded EXE file? NativeProcessInfo.executable needs a File object, and not a byte stream.
The only idea I have would be to embed the EXE file with [Embed], load it as a byte array, create a new file with the byte array as data, and then execute the file. I don't know if it works, but I do not like the idea, as it implies having the EXE kind of duplicated.
Does someone have an idea?
Thank you!
You should look into the Air Native Extensions. Simply put, one of the a new features in Air 3.0 was the ability to compile and link to custom language extensions directly from air. I haven't found an example of using C# directly, but there is a link on that page to doing with managed C++.

How to effectively load SWF libraries?

I am making an AS3 project in FB4. In our workflow, we have artists compile art into SWC files which the I then link as 'Referenced Libraries' in FB4.
Then I set the "Link Type" of the SWC files to "external" instead of merged into code. This should create SWFs corresponding to the SWC files in the output folder, right?
This doesn't seem to be the case. I am only seeing one SWF file: the main_app's.
I was trying to make it so that I can use a library manager to load the files dynamically.
I tried extracting the swfs manually, but it seems the main_app still compiles all the swcs to itself. I made sure the Link Type was set to external. The file size for the main_app between "external" and "merged to code" seem to be the same.
I've made a simple project in Flash Builder 4 and the only way I got the SWC->SWF happening is by creating a Flex Project instead of an ActionScript Project and selecting "Runtime shared library (RSL)" instead of "External". This is because the Flex framework have some classes that work out the loading of those libraries for you. It also automate the conversion (I should say extraction) process.
Now, if you don't want to create a Flex project just for this, you can extract the SWF yourself. The SWC file format is just a Zip containing a SWF and an XML file describing the content. You can then load dynamically this extracted SWF file using a Loader and setting the correct Application Domain. Here's a snippet of my sample project.
public class Web extends Sprite
{
public function Web()
{
//you will not be able to instantiate classes of your library until it's loaded
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoadComplete);
loader.load(new URLRequest("library.swf"), new LoaderContext(false, ApplicationDomain.currentDomain));
}
protected function onLoadComplete(event:Event):void
{
//here you can create instances of classes defined in your library
new Asset();
}
}
You might think that's a pretty tedious job to unzip+copy every time your designers update the library. You could automate this process with a script or an Ant file. Unfortunately, unless I'm missing something, it looks like Flash Builder doesn't want you to extend your build process, so you will still need a bit of hand work or completely convert to Ant (or something similar) to build.
Good luck!
From the moment the SWC is added to your Library, you should be able to access the SWC's assets by directly calling their specific class names . There's no need to try to get a SWF and load it with the Loader class. This actually defeats the purpose of using a SWC in the first place!
Let's say that , in your SWC, you have a MovieClip with a class name of GraphicAsset, to create a new instance , you simply do this:
var mc:MovieClip = new GraphicAsset();
In FB4's folder structure , have a look at your SWC in the Referenced Libraries folder & check the default package, you should see a list of all your assets.

How to import actionscript library and call function?

I need to develop something with data structure and how do I import the library as3ds (http://code.google.com/p/polygonal/wiki/DataStructures) and call the function of the library? It is in swc file format for the new version. While the older as3ds is in as format. I've no idea how to call using the swc. Anyone can help me please?
just place the .swc file where ever you want (usually in your own developer library) and target its path in ActionScript 3.0 Settings of Flash CS5: File > ActionScript Settings... (see attached screen shot).
you could also just place it in with your other library swcs. Flash CS5/Common/Configuration/ActionScript 3.0/libs/
if it's a component, create a folder for it and place the folder in the components folder: Flash CS5/Common/Configuration/Components/
