AS3 Blender exporter has been updated to allow multiple object export. Also in April is was updated to export quads and modifiers.

One concern you might have is statically binding the code within a main swf fileon compile and resulting file size compared to loading in the DAE dynamically.  But you can just load these in as you would external DAE COLLADA files as compiled swfs and since it is just code it is very compact.   This adds some duplication of code (such as tweening libraries or the 3d engine source as needed) but allows a more horizontal loading or lazy loading of meshes when needed.

This is just another option to get 3D models into the flash 3d engine of your choice in addition to COLLADA, some MD2 support and limited ASE support.

This is an awesome project that keeps getting better, thanks Rozengain.

Face Detection: Here is the sample included with Marilena showing facial detection on an image.

Lots of recent action has blown up on this front from Mr doob, quasimondo (optimizing the Marilena classes for better performance) and Boffwswana. Also there is a kit called deface by sshipman that is the first foray into this a year ago doing similar things but it was just a bit before it’s time and a bit slow in previous versions of flash, it performs decent now in this sample. Flash 10 performance of the AVM2 and future directions with Alchemy will lead to more interesting stuff just like this.

Mr. doob head tracking sample, be sure to check lots of other examples there

Boffswana example of head tracking Johnny Lee Wii style with only a webcam and flash, no wiimote needed since it uses facial detection to check where you are and how close you are in the screen and then moves accordingly.

This is stemming from the recent explosion of the FLARToolkit and augmented reality in flash as well as the gimmicks used by Nintendo with the wii and Johnny Lee’s great head tracking advancements. Porting great libraries to flash seems to be the phase we are entering now judging by the recent excitement around Adobe Alchemy and the LLVM along with the lead from the libspark.org contributors. We have also seen this heavily last year in ports of Box2D for 2d physics and other toolkits using established working code and porting that to flash now that is is mostly capable of handling the performance.

OpenCV (Open Computer Vision Library by Intel) is quite a powerful platform that allows you to do all this and now it is available in flash. There are other great libraries for nearly all platforms now. I have done some previous work with Aforge which is also a port of OpenCV mainly for motion detection. This was always around but not until the recent performance updates and the innovation that has come with Alchemy and the thinking that goes along with that (porting in libraries to flash from C/C++ etc), has allowed this to flourish in flash and thus the web.

The amazing new things we can do with flash by porting in existing libraries is only going to get more intense as alchemy and flash 10 are even more mainstream.  It is almost as if Flash will eventually just become a web renderer and simplified front end to many great toolkits that exist in more native environments like C/C++ but with the speed and distribution access of the web with Flash.  Exciting times ahead.

UnityDevelop was released by Flashbang Studios recently and it is a modded version of FlashDevelop (originally from SharpDevelop a really nice open source .NET and mono IDE) and it supports intellisense for Javascript or Unity3d’s use of Javascript which is called UnityScript much like ActionScript.  UnityScript can be a little more strict and has access to all of Unity3d’s API calls just like C# and Boo in the mono based virtual machine that Unity3d uses.

FlashDevelop, is by far the best Flash / Flex /haXe IDE in my opinion so it is really great to release this for Unity.  I hope one day I or someone has the time to port to Mono so it can be used on Macs even with the 140 pinvokes, it would be a good spread mechanism for mono.

With Unity3d coming to windows soon, UnityDevelop could be a good go to IDE for unity if you aren’t using solely C# with VS.NET. Currently this is based on FlashDevelop2 source code.

Thanks flashbang!

One cool thing about it is the IDestroyable interface and the CasaMovieClip, CasaSprite, CasaTextField , etcthat all have a destroy() method that cleans up all events, removed instances and even removes it from the parent display object. Gets me thinking why this isn’t just part of DisplayObject in the first place.

From the release:

Here are a few of our favorite things in CASA Lib AS3:

• Standardized external load API
• Easily remove listeners with IRemovableEventDispatcher
• destroy methods make garbage collection easy
• Large group of utility classes for common manipulations

We will be elaborating further the power of CASA Lib in future blog posts.

As with any new release there will be bugs that emerge, but with your help we promise to release updates often to keep CASA Lib as stable as possible.

The latest haXe file format library contains complete support to read and write PBJ file, enabling you to write Pixel Bender assembler directly in haXe, then compile it on-the-fly into PBJ bytes, which can then be saved on disk or loaded directly in Flash.

I plan to have much more on Pixel Bender (shaders in flash) and Adobe Alchemy (compile other languages to which is a very cool technology that involves LLVM that Nicolas also has lots of great input on.

Paul Tondeur threw togetother a little sample that shows how you can integrate Unity3D, Flash and javascript in the page fairly simply with lots of great demos.  It really is just about passing parameters around into the objects from javascript, then within Flash calling ExternalInterface to call external javascript or within Unity3D calling Application.ExternalCall.

//Flash adding callback for javascript code
ExternalInterface.addCallback("functionNameInBrowser", functionNameInFlash );

//Unity3D calling javascript code
Application.ExternalCall("javascriptFunction", "Parameter1");

Nothing too tasking but if you want to see samples of this working together from flash, flex, javascript, unity3d then check it out. Zip on over to Paul’s site to grab the files and more demos and samples. All examples are bundled in one download, which includes all the Unity3D, Flash, Flex, Actionscript and Javascript files.

Here’s some demos

• Build a Unity3D “browserchat”
• Make Unity3D objects clickable and load content in Flash
• Drag a rectangle in Flash and drag an cube in Unity3D
• Add, delete and drag objects from the Flash interface and show this in Unity3D

as3isolib is a great isometric library for actionscript 3

From building basic blocks…

To constructing sprites and objects with individual iso objects with their own bounding boxes.

This sample shows a two piece tree, a common issue with sprites in isometric is where to slice them up.  This sample shows a tree with the leaves able to be in front of a character so that you could walk under the tree and be in front of the trunk but covered by the trees.  Essentially height is respected.

Sample code for the tree tutorial:

package
{
import as3isolib.display.IsoSprite;
import as3isolib.display.primitive.IsoBox;
import as3isolib.display.scene.IsoGrid;
import as3isolib.display.scene.IsoScene;

import flash.display.Loader;
import flash.display.Sprite;
import flash.events.Event;
import flash.net.URLRequest;

public class IsoApplication extends Sprite
{
 private var scene:IsoScene;
 private var assets:Object;

 private var loader:Loader

 private function loadAssets ():void
 {
  loader = new Loader();
  loader.contentLoaderInfo.addEventListener(Event.INIT, loader_initHandler);
  loader.load(new URLRequest("assets/swf/assets.swf"));
 }

 private function loader_initHandler (evt:Event):void
 {
  buildScene();
 }

 private function buildScene ():void
 {
  scene = new IsoScene();
  scene.hostContainer = this;
  scene.container.x = 200;
  scene.container.y = 200;

  var treeTrunkClass:Class = loader.contentLoaderInfo.applicationDomain.getDefinition("TreeTrunk") as Class;
  var treeLeavesClass:Class = loader.contentLoaderInfo.applicationDomain.getDefinition("TreeLeaves") as Class;

  var grid:IsoGrid = new IsoGrid();
  grid.showOrigin = false;
  scene.addChild(grid);

  var s0:IsoSprite = new IsoSprite();
  s0.setSize(25, 25, 65);
  s0.moveTo(50, 50, 0);
  s0.sprites = [treeTrunkClass];
  scene.addChild(s0);

  var s1:IsoSprite = new IsoSprite();
  s1.setSize(125, 125, 100);
  s1.moveTo(0, 0, 75);
  s1.sprites = [treeLeavesClass];
  scene.addChild(s1);

  scene.render();
 }

 public function IsoApplication ()
 {
  loadAssets();
 }
}
}

The benefits of COLLADA are nice but there are so many differences that you can run into trouble.  With the exporter it is a direct faces and vector export without all the bloat of DAE/COLLADA xml.  This works if you are only developing for flash and dont’ need to use the models in other platforms/systems/engines that aren’t in flash.

Here’s and example of our Library & LibraryManager classes that we use in some of our Flex and AS 3.0 projects to manage our external assets stored in SWF’s.

The classes enabled you to create multiple libraries of embedded (retaining and giving access to code) or loaded SWF’s.

You can create instance of Library wherever you want, but you can also create them through the LibraryManager giving you a single class to gain access to all your Library instances.

As you develop more and more flash/flex projects with AS3 these types of utilities come in handy. Another that comes to mind is Arthur Debert’s BulkLoader and polygonal labs Data Structures for Game Developers that are all great kits.

Add Tink’s Library and LibraryManager to your arsenal today! Thanks Tink.
