Hi,

I've been having a look at the HUD guide in the Xith in a Nutshell documentation and have been trying to
get some of the example code working. However I don't seem to be able to find any compatible code /
libraries to get it working.

My code...

        env.addRenderPass(hudPass);
        
        this.begin();
    }
}

I had a lot of problems to begin with and have changed the code to try and update it. I checked out
a new copy of xith3d and xith-tk from CVS, built new jars and added them to my project but then I
got a missing class error from net.jtank.input.InputListener. I managed to fix this by finding the class
in an earlier release of xith. My project now compiles but when I try to run it I get the following error

Exception in thread "main" java.lang.NoSuchMethodError: javax.vecmath.Matrix4f.setTranslation(Ljavax/vecmath/Tuple3f;)V
        at com.xith3d.scenegraph.Transform3D.lookAt(Transform3D.java:691)

        at org.xith3d.render.base.Xith3DEnvironment.<init>(Xith3DEnvironment.java:1381)

Is there a different version of vecmaths I need to download?

Also is there an easier way to try the examples from the "Xith in a nutshell" as I have found
it really difficult.

Thanks,
