Re: [away3d] Exporting to AS3 with animation from PreFab

[Fabrice3D]

 It would be nice to keep it in there as a
backup even when PreFab gets all the bells and whistles I know you're
working on ;)
no, no, not everything turns around Prefab, the exporters in Prefab  
are all in the trunk
The Air versions with embeds of assets as well.
 I had a couple of memory issues compiling my app the first time
Thats one of the reason why it will be gone as soon as all exporters  
are able to support mesh animation properly.
where you can set like +-4000 faces info into a class using this  
method, the exporters are able to handle up to 100k
without a memory issue. So basic idea is to merge both code and Prefab  
will just follow once done.

Is there any way of centering the mesh (as with the  
loader.centerMeshes()
you mean this?
m.applyPosition( (m.minX+m.maxX)*.5,  (m.minY+m.maxY)*.5, (m.minZ 
+m.maxZ)*.5);

note that md2 is not updated on bounds for performance reasons
so best way to do it, is to loop of the vertexes and frames to define  
your bounds and applyPosition with this bounds values.

Looking forward to the new features in Prefab, I've read your hints on
what to expect and I'm pretty excited! Even as is there's no better
utility for the quick viewing and editing of assets.
thx! I just try to add usefull features, not just a pure reflection of  
the engine.
Feel free use the report option if you have comments/wishes etc...

Cheers Fabrice!

I didn't know the asAS3Class() method existed - that's a fantastic
piece of functionality! It would be nice to keep it in there as a
backup even when PreFab gets all the bells and whistles I know you're
working on ;)

I've been testing it this morning and it works amazingly well. I had a
couple of memory issues compiling my app the first time round because
of the size of the class (Flash error 5003) which i was able to fix by
making amendments to my environment.plist file as detailed here:
http://code.allofus.com/2009/08/flash-error-5003-5005/

a last question:
Is there any way of centering the mesh (as with the
loader.centerMeshes() method) with the generated class? It's not a
major thing, since I tend to load within ObjectContainer3Ds anyway,
but it'd be good to know.

Hi Kevin,

Really happy to read that you use Prefab.
Make sure you check the update btn often, I'm busy with it atm and  
upload
updates almost dayly.

I haven't been able to export an AS3 with animation as of yet.

Thats correct. Prefab doesn't support mesh animation export at the  
moment.
It will, you can bet on that, and probably way more than you  
espect...
For now, to export to as3, you will have to use away3D and do it by  
code
just load the md2, once loaded, add the following line
lets say your md2instance is mymd2
(mymd2 as Mesh).asAS3Class("MyClassName", "mypackagename", true,  
true);
in F9 just after the swf is compiled, open a texteditor and paste.  
The class
string was set into your clipboard
in F10, since it requires user interaction to allow clipboard fill
var myclass:String = (mymd2 as Mesh).asAS3Class("MyClassName",
"mypackagename", true, true);
then print that string using debug trace or fill a textfield.
The output works only for a mesh. You will not be able to export  
more than
one per class like all other exports
In your project, addchild the imported class, and play the md2 like  
you use
to.
Later on, animation support will be added to other exporters as  
well, if you
look at code level, you will see that
the code is already implemented but commented or desabled for now.
This way you should be able to export a whole scenery or whatever  
you want,
and if mesh animation is detected, it will export it as well.
Once done, the Mesh method, asAS3Class, will be removed.

Hey all,

I've been using the amazing Prefab quite a bit lately to do lots of
little things such as normal maps, scaling, and exporting static
models. However, I haven't been able to export an AS3 with animation
as of yet.

I've got an MD2 model with animation which was built in Blender by a
3d artist. The MD2 loads into Away3D fine, and loads into prefab ok  
as
well. But when I try and export it to an AS3 Away3D class, and load  
it
into Away3D i get this error (my class name is Rock):

TypeError: Error #1009: Cannot access a property or method of a null
object reference.
at away3d.core.base::VertexPosition/adjust()
at away3d.core.base::Frame/adjust()
at Rock/setMeshAnim()
at Rock/buildMeshes()
at Rock()

if I comment out this line:

if(ref.meshanimated) setMeshAnim(this, ref, oList.length);

I can get the model to load, but of course, it doesn't animate.  
Anyone
have any idea why?

Kevin.
