AS3 FVorbis Flash Ogg Vorbis Player

This project is stacked with cool, but is also useful, an ogg/vorbis player in flash/as3.  Arek Korbik at barelyfocused implemented a port for a pure Ogg/Vorbis audio library called FVorbis.  Check out the demo (need flash player 10). Groovy.

The name is: FVorbis. Which stands for more or less “Ogg and Vorbis in Flash”. That’s right, pure ActionScript 3 implementation of the Ogg and Vorbis libraries that require no kind of native support from the Flash Player. A simple Vorbis player implemented using the new FVorbis lib compiles to about 46KB SWF file. And that’s it.

To top it off the code is actually written in haXe, a favorite of the flasherati. This version was iterated from the Cortado’s JOrbis code.

Ogg Vorbis is a great open source audio format which is widely popular in game engines such as recent tools like Unity3D (which will be launching their iPhone dev kit on Oct 22 btw but I digress), so it is great to see it starting to appear in flash. Thanks Arek.

AS3 Flash 3D Engine SWFZ Source Code Goes Open Source

Jono is giving SWFZ to science and the open source devices.

The SWFZ engine is one Flash 3D engine that took a different approach. It is a bit early in its technique used but the author at custom:media Jono has decided to float the source code out there in ghost mode (no active development but not dead). It is just ready to branch and others to run with it. He is floating the source but I think in 1-2 years this will be the preferred method if processors and multicore parallel usage is optimized. We shall see.

The implementation method and difference with SWFZ engine in Flash for 3d is that is is a pixel based renderer or scanline. It is based on a really fun game engine called Irrlicht which has been pretty active for the last few years but is a C++ DirectX and OpenGL engine. Since SWFZ has to run in Flash and it is a pixel renderer/scanline it has some limitations currently in Flash. Games and renders have to be fast to pull this off and Flash is limited by the software renderer but as computers get multiple processors and flash player gets better at this then this will be a viable option (it is the same thing that limits Canvas based renderers right now). One main problem with this is you can’t go too full screen the biggest sizes that perform well are smaller windows 320×240 etc. But if the processors can handle it it is actually more efficient when it removes overlap, extra triangle drawing and painters algorithm like problems dont’ pop up (triangle overlap when on same plane). This method draws pixel by pixel but fast enough flash engines like Papervision, Sandy3D and Away3D draw overlaps due to the drawing technique, back to front.

But SWFZ still manages to pull off some amazing feats such as these demos

Quake Demo

Terrain Demo

Yoshis Hip Hop Couzin

Jono has put some great classes into SWFZ engine such as bsp parsers, quake md2 parsers, animated mesh, and lots of great examples in porting C++ Irrlicht to AS3. This was a very early example of how AS3 was fun for programmers to port stuff from C or C++ into Flash. AS3 is just fun. Also be sure to check the site for more samples like an FPS game, some basic ai etc.

Jono has been working on 3d in Flash for a while and actually this message is what shows the difference betweeen this approach and other flash engines the way Papervision, Sandy and Away3D (pv3d derivative) make 3d in flash fast enough (Painter’s Algorithm and drawing skewed movieclips and textures.


More about the Engine Some Notes

The SWFZ engine.


SWFZ engine is the result of four years of me messing with 3D in Flash.

I was a complete newbie to 3D, so a lot of learning has happened to get to here.

If you’re interested in 3D engines check out the resource links at the bottom of the page:

The Demo:


  • .md2 format from ID’s Quake2.
  • Uses frame based animation
  • Textured with jpeg
  • No lighting, No Gouraud Shading, just plain texture


  • Textures are just jpegs.


  • Rendering – Textured Gouraud , Textured Gouraud with Alpha, Textured Gouraud with Quick Alpha, Gouraud Shaded, and the large box is just Textured.
  • Star Texture – Targa (.tga) file format.

AS3 classes

  • 171 classes and interfaces


  • No lighting
  • No collision detection

SWFZ engine technology:

The demo only shows a small part of the capabilities of the engine. In the coming weeks I will get up and running and start to post more info then.

Currently implement stuff:

New file formats supported

  • .tga – Targa Image
  • .bmp – Bitmap Image
  • .3ds – 3D Studio Max
  • .bsp – Quake3 levels
  • .md2 – Quake2 models
  • .obj – Wavefront 3d object (static)
  • .zip – Read from a zip archive (all in Flash, no server side scripts)

3D Rendering

  • mipmaps
  • perspective correct texturing + affine texturing
  • Flat shading
  • Gouraud
  • Textured Gouraud
  • Textured Flat
  • Textured Two Layers
  • Gouraud Alpha
  • Textured Flat Alpha
  • Textured Gouraud Alpha

3D Scene

  • Billboards
  • Parent, Child scene nodes
  • OctTree
  • Skybox
  • Static Meshes
  • Animated Meshes
  • Basic collision detection
  • Scene node animators

If any code is useful to you maybe drop him a donation or what would be nice if this was all setup at google code and used to be integrated into other engines. Irrlicht ports are fun and there is a future in this method when processors catch up I think.

TweenMax Bezier Tweening Released for AS2 and AS3 by Jack at GreenSock – And List of Animation Kits

TweenMax (Speed Test) has been released that adds a main feature missing from GreenSock’s offerings in tween animation libraries and kits over Tweener. That is the bezier curve tween. Tweener is very popular for use in PV3d and AS3 due to the bezier curve and Zeh’s great example that is really the base of a possible 3d editor. TweenMax now adds this and bezier tween capability for the GreenSock animation libraries.

Tweener and TweenLite have become the micro animation kits as well as micro kits you can make with Go base kits. TweenLite, TweenFilterLite and TweenMax divided up into different kits allows it to be embedded for banners or small assets easier if you don’t need the filters or other advanced tweens (this comes into play heavily with large games and asset collections when the compiled SWF each need the library). Tweener packs all features into one kit for simplicity. GreenSock kits are divided up for need. The comparison together is about the same but for basic tweens TweenLite is only 2k.

Performance is one area that the kits from GreenSock have really shined and since the addition of the speed tests and benchmarks it has become a great focus on showing how the open source kits are much better than bloated included animation calls in Flash and Flex defaults. I think all the kits have niches that they fit and Tweener and TweenLite are just very simple to use which adds alot to an animation kit success.

List of Animation Kits for AS3 (some for AS2 as well)

If you are using the Flex of Flash default animation classes, I am sorry…

AS3, Convert Python Code to Flex AS3 with flex-pypy

I have officially been sucked into the Python vortex. I recently have really been digging IronPython, Jython and good old plain Python but have not ventured here yet. Google (They employ Guido), Microsoft (IronPython) and Sun (Jython) are all becoming infected pythonistas as well. But this is just too cool, Python to AS3 code with flex-pypy. This project is very young but could be fun, source at Google Code.

Haxe has a similar premise where it can compile to Flash6-9 versions of actionscript 2-3 which makes for a system with better reach. Python code for this is lots of fun and very flexible. Python is becoming a baseplane language and one great language for transcending platform lock-in.

Check out this snippet pulled from here (click to see sample game)

#/usr/bin/env python
This simple example has very little to do with the pygame
chimp example, except that it will act the same (more or less)
and it uses the same resources, only they got converted to
mp3s, pngs.
