haXe is an open source and multiplatform programming language. To learn more and get the latest info on using haXe and the platforms it targets, check out the haXe's Introduciton.

To get started with haXe, you'll need to download a few extra add-ons.

Download haXe

Visit haXe's download page Img preview.png, and download one of the automatic installers for your platform. For this example, we'll be installing haXe for OSX.

While installing, the installer may ask you to install Neko. Neko is a language / Virtual Machine platform that comes with the installer. Even if you've never use Neko and haXe together, it may come in handy in the future so go ahead and install that as well Img preview.png.

When the installer is complete Img preview.png, confirm that the installation of haXe was successful by opening your console and executing the command haXe:


If installed correctly, the console should print out haXe info:

OSXs-MacBook:~ OSX$ haxe
haXe Compiler 2.06 - (c)2005-2010 Motion-Twin
 Usage : haxe -main <class> [-swf9|-swf|-js|-neko|-php|-cpp|-as3] <output> [options]
 Options :
  -cp <path> : add a directory to find source files
  -js <file> : compile code to JavaScript file
  -swf <file> : compile code to Flash SWF file
  -swf9 <file> : compile code to Flash9 SWF file
  -as3 <directory> : generate AS3 code into target directory
  -neko <file> : compile code to Neko Binary
  -php <directory> : generate PHP code into target directory
  -cpp <directory> : generate C++ code into target directory
  -xml <file> : generate XML types description
  -main <class> : select startup class
  -lib <library[:version]> : use a haxelib library
  -D <var> : define a conditional compilation flag
  -v : turn on verbose mode
  -debug : add debug informations to the compiled code
  -help  Display this list of options
  --help  Display this list of options

If it doesn't - try restarting your computer or reinstalling it again.

Install FDT's haXe Plugin

  • Start up FDT 4 and select Help>Install new Software Img preview.png.
  • Select the FDT Plugins Site update site Img preview.png (If it is not included in your drop down menu, enter: in the Work with text input and hit return).
  • Select "FDT haXe Plugin" from the plugin list Img preview.png, hit Finish and follow the final installation steps.

Setting up the haXe Plugin

Before authoring and compiling haXe, you'll need to define the haXe SDK location for FDT to reference. Open FDT's preference widow and navigate to HaXe>SDK Img preview.png and input the installation directory of haXe. If you're not sure where haXe is installed, the installation window will clue you in Img preview.png. Here we can see that the installer is moving files and creating links to /usr/lib/haxe - this is the default location for OSX. After inputing the sdk location, hit OK Img preview.png.

Create Your First haXe Project

All haXe projects begin with a Flash Project base and then are converted to a haXe project. Begin by creating an Empty AS3 Project Img preview.png and then create a new HaXe class by right clicking on src and choosing Other Img preview.png. When the wizard pops up choose HaXe Class Img preview.png and give the class the name Main and hit Finish Img preview.png.

Convert Project To A haXe Project

With your first class created, right click on the project and select Add HaXe Project Nature Img preview.png. When this happens, FDT will ask you to input some project variables. We already have configured our HaXe SDK Location so just hit Next Img preview.png.

Let's leave the haXe configuration file to the default location but modify the Output Path to bin/Main.swf Img preview.png. When completed, FDT will have created a few extra files and folders for us. We don't need to worry about .hxtypes but we use project.hxml to set configurations to our project Img preview.png. We can also see that FDT has begun to parse our project for syntax errors Img preview.png.

Adjust Compiler Settings

Before writing some code, let's alter some compiler options - this is done via the project.hxml file. Open us the file by double clicking on it Img preview.png and then add this argument to the bottom:

-swf-header 550:400:40:FFFFFFF

Here we are setting the Width and Height properties to 500 x 400 Img preview.png.

Compiling and Viewing your .SWF

Adding haXe Code

The syntax of haXe is a bit beyond the scope of this tutorial - but that doesn't mean we have to code something boring! Copy and paste the code below to make a simple animation Img preview.png. Or type in the the code yourself to begin exploring the syntax auto completion FDT provides Img preview.png.

package ;
import flash.display.Sprite;
class Main{
	static var view:Sprite;
	static var x: Float = 0;
	static var y: Float = 200;
	static var speed :Float = 20;
	static var max_x : Float = 550;
    static function main() {
		 new Main();    
    function new(){
    	view = new Sprite();
    	flash.Lib.current.addChild (view);
    	flash.Lib.current.stage.addEventListener(Event.ENTER_FRAME, update_view);
    function update_view (e: Dynamic){;, 1);, y, 50);
    	if(is_invalid_x()) speed  = speed * -1;
    	x+= speed;
    function  is_invalid_x() : Bool {
    	return x > max_x || x < 0;

Compiling haXe

For the time being, FDT will automatically attempt to compile your .SWF every time you save it. If there are no errors in your project, your .SWF will appear in your bin folder Img preview.png. If it doesn't appear, try refreshing your project Img preview.png.

View Your SWF

As this FDT plugin is still in it's early stages, there are no launch configurations to automatically view your .SWF - but we can make a simple Ant script to view our .SWF! We'll quickly go over a simple script to view our .SWF but for more in depth know-how on using Ant, check out the FDT and Ant Tutorial.

Create a new Ant script by beginning with a simple XML file by right clicking on the project and choosing new>other Img preview.png and then select an XML file to create Img preview.png and hit Finish. Give the script any name you like, this one is called view_swf.xml and hit Finish Img preview.png.

Next, copy the code below to have FDT launch the external .SWF viewer Img preview.png:

	<target name="view.swf">
		<fdt.extSWFViewer.startSWF width="550" height="400"

Then, drag your .XML file to the Ant view Img preview.png and double click the target to launch Img preview.png. You will then see a red ball moving back and forth on the screen.

  • note: If you get an error while tying to run the Ant file, it's probably a JRE error, check out the FDT and Ant Tutorial to learn how to correct it.

Wrap Up

That's it, you've successfully set up your first FDT haXe Flash project!

As this plugin is still an Alpha release, please bare with us! For any feedback, feature requests, improvements, bugs and other issues we encourage you to use our community driven tracking website to make the haXe support in FDT the greatest ever. We also suggest anyone anyone interested in haXe developement to subscribe to the haXe mailing list. It's a very active group with smart people and interesting topics.

On the behalf of the FDT Team and Influxis, we hope you are as excited as we are and enjoy the FDT haXe plugin.
