• Install Flex 2 SDK .
• Install FlashDevelop 2.0.2+ .
• Follow these directions, summarized below:
  • In proram settings, set ASCompletion.Flex2SDK.Path to the root folder of the flex2 SDK install
  • Download intrinsic classes (mirror) and extract somewhere. Add to global classpath.
  • Remove all references to Macromedia in Global Classpath
  • Download as3_toplevel, extract somewhere. Set ASCompletion.Macromedia.Classpath to the folder containing toplevel.as
  • Set ASCompletion.MTASC.UseStdClasses to false.
  • (only for mxml: put xml file from this zip into FlashDevelop/Data)
• To compile, add a @mxmlc tag to the very top of your main AS file. More info on @mxmlc tag. Example:

/**
* @mxmlc -sp+=G:davidrpapervisionas3src
*/

• NOTE: Make sure the entire @mxmlc string is on one line only
• Press Ctrl+F8 to compile & run!

• Simply add this code right above your main class definition:

[SWF(width=“800″, height=“600″, backgroundColor=“#ffffff”, frameRate=“30″)]

public class MyMainClass extends Sprite
{

• http://www.senocular.com/flash/tutorials/as3withmxmlc/ . some short tutorials. If using FlashDevelop as above, don.t need to fiddle with .bat files or commandline, but the rest of the info is still good. Has HelloWorld, Drawing API, and simple EventHandling (onEnterFrame, mouse clicks, etc)
• AS2 to AS3 quick reference . good for quickly looking up how things changed between AS2 and AS3
• AS3 Language Reference
• Developer Guide (slow) . (PDF)
• Getting Started with Flex 2 (slow) . (PDF)
• Programming Actionscript 3 (slow) . (PDF)
• AS2 to AS3 Migration Guide (PDF)
• Links to all documentation
• Handy list of AS3 libraries

• Blog | AS3 Docs | Official site | OSFlash page
• Check out the source from http://svn1.cvsdude.com/osflash/papervision3d/as3/trunk . put this URL directly into TortoiseSVN
• Make sure to add the .src. directory to your classpath. This can be done by adding the directory to the -sp argument in your @mxmlc tag

• You can easily embed assets using the [Embed()] tag in your .as files.
• NOTE: The path to the assets is relative to the .as file!

public class Main extends Sprite {

  [Embed(source=“logo.png”)]
  public var Logo:Class;

 
  public function Main() {
    var logo:Bitmap = new Logo();
    addChild(logo);
  }

}
