Hi everybody,
could you please have a look to my #~@@@ problem ?

i'm new with Xith3d and i try to run xith's Ase source exemple from Eclipse.

This is the piece of code wich throws me an exception error:

     private void loadGeom() {
           try {

                  * Loads the ASE file
                 AseFile af = new AseFile();
                 BufferedReader br = null;
                 try {
                       // Attempts to read the file normally
                       br = new BufferedReader(new FileReader("crudetank_mod.ASE"));
                 } catch (IOException e) {
                       // Attemts to read file from JAR
                       URL url = this.getClass().getClassLoader().getResource("crudetank_mod.ASE");
                       br = new BufferedReader(new InputStreamReader(url.openStream()));
                 AseReader r = new AseReader(br, af);
                 torso = new BranchGroup ();
                 tankbody = new BranchGroup ();
                 turret = new BranchGroup ();

                 // Extracts list of named nodes
                 java.util.Hashtable views = af.getNamedNodes();

                 // Iterates though nodes, adding them to relevent base branch groups
                 for (Enumeration e = views.keys() ; e.hasMoreElements() ;) {
                       String current = (String)  e.nextElement();
                       if (current.equals("Torso")) {
                             torso.addChild((BranchGroup) views.get((Object)current));
                       } else if (current.equals("Body") ) {
                             tankbody.addChild((BranchGroup) views.get((Object)current));
                       } else if (current.equals("Turret")) {
                             turret.addChild(((BranchGroup) views.get((Object)current));

The excpetion is :
     at Ase.CrudeTank.loadGeom(
     at Ase.CrudeTank.<init>(
     at Ase.AseTest.<init>(
     at Ase.AseTest.main(

I would like to debugs it.
But before getting started i was wondering; why is there screenshots of this exmple, if it has never worked before.

i know that the .ase file has been read, and that te enumerator is full of stuff, it seems to be a casting problem between BranchGroup and the Node object.
So why does this probem occurs on my pc if this piece of code is supposed to be working ?

Thanks for your help

Konik and i found the reason.

The casting of (BranchGroup) is responsable of the exception it works fine with (TransformGroup).

We have now a nice tank rotating Wink

Have fun

My bad Sad

Problem was caused because I changed getNamedNodes to return TG's rather than BG's.  I've patched the souce but it may take a few days to sync with the server.

Thanks for pointing out the bug.

If you liked that tute, I strongly suggest checking out this one:

getTransformGroupTree is quite a lot more useful than getNamedNodes for many situations Smiley
