It talks about using getChildByName() in Papervision. I just applied this to my joints in my dae file and I can now Tween my joint positions with ActionScript! The annoying part of it is that you need to go through your joint chain to find the right joints. But if you name your joints correctly and use your model in your 3D program as a reference, you can quickly create variables for each joint. Here is an example:

var LHand:Display 3D = dae.getChildByName(“COLLADA_Scene”).getChildByName(“Root_Joint”).getChildByName(“LShoulder_Joint”).getChildByName(“LArm_Joint”).getChildByName(“LHand_Joint”)

Of course, you can’t use your IK but if you do the math you can convert your FK to IK with equations. Anyway, I’m pretty excited about this.

After spending 3.5 weeks reading cover to cover (the book recommended), trying out your “Break.as” class found inside the SVN REPO and NOT the advertised downloadable AS3MOD package (and realizing it doesn’t work that good), my making several mistakes… mathematically and conceptually…, after two weeks of hacking away… I made my first ActionScript-based 3D Forward Kinematic Bone System… capable of N-nodes for massive jointed structures…

It’s still raw, this is why I haven’t posted it. And unfortunately my system uses joints and not breakable single meshes. Would have loved to have seen YOUR source code. Because while my idea definitely works, I could have benefited from your information.

want the source code of it

just wanted to correct you on the Away3d bones thing – an imported collada model with bones has exposed obejcts which allows full control of each joint programatically. you can use the method getBoneByName() on the object container in exactly the same way as you would normally use getChildByName() to retrieve a mesh, and one returned, using jointRotationX/Y/Z will allow you move the bone any way you want
