Re: [GreatWhite] DAE and MD2 now implement basic animation

I have tried dae exports from blender and maya and seem to have problems here:

[trace] Animation channel with target SID='translate' does not target a matrix! (type=translate)
[trace] Animation channel with target SID='scale' does not target a matrix! (type=scale)
[trace] Could not find a transform with SID=visibility
[trace] Animation channel with target SID='rotateY' does not target a matrix! (type=rotate)


I have tried changing the collada file and even modifying your code in the DAE parser but I am still unable to get the animations to come through. at one point I got the parts that were supposed to animate to disappear =) but that's it.

What program are you using to make the bone based DAE files?

Hi all,

Just added simple animation for DAE and MD2.
Both now implement the IAnimatable interface, which has 2 methods:
1] IAnimatable.play( clip : String = null )  : void; => Starts the
animation (@param clip is mostly used by MD2: md2.play( "run" ),
md2.play( "wave" ), etc.
2] IAnimatable.stop() : void;  => stops the animation

Changes:
1] DAE and MD2 have a new @param 'autoPlay' in their constructors. If
true the animation will start automatically.
2] When file is completely parsed FileLoadEvent.LOAD_COMPLETE is
dispatched (was Event.COMPLETE)
     => NOTE: animation-data still needs to get parsed at this point,
see below...
3] When all animation-data is parsed from the file then
FileLoadEvent.ANIMATIONS_COMPLETE is dispatched.

Usage:
var dae : DAE = new DAE( false );  // lets show when 'autoPlay' is false...
dae.addEventListener( FileLoadEvent.LOAD_COMPLETE, onLoadComplete );
dae.addEventListener( FileLoadEvent.ANIMATIONS_COMPLETE, onAnimationsComplete );
dae.load( "myfile.dae" );
scene.addChild( dae );

private function onAnimationsComplete( event:FileLoadEvent ) : void
{
    if ( event.target is DAE )
    {
        var dae : DAE = event.target as DAE;
        dae.play();
    }
    else if ( event.target is MD2 )
    {
         var md2 : MD2 is event.target as MD2;

         md2.play();
         // or :
         // md2.play( "wave" );  // 'wave' is one of the clips defined
in the md2.
    }
}

private function onLoadComplete( event:FileLoadEvent ) : void
{
   // not used
}

Have fun!
Tim
