There is also some info log about the exception :

Hope it helps, I know the error is not about the Loader class, but it occurs after I've tried to load serialized object from the server so I guess it is the problem.

Thanks for the quick reply

Support / Serialization problems -> nullPointerException in Object3D.transformVertices
« on: December 14, 2011, 04:35:22 pm »
Hello there,

I've been trying for a while to send simple 3D objects from a server to an android device using the DeSerializer class on the server and the Loader one on the client. The object is loaded on client-side but it does give me an NullPointerException for Object3D.transformVertices when trying to rendering the world and I don't know how to fix it...

Any suggestions ?

Here's the source code server-side : (exemple with a cube)

Code: [Select]

Object3D obj = Primitives.getCube(1);
obj.setTexture("rouge");
obj.build();
_deSerializer.serialize(obj, os, true);
                byte[] serializedObject = os.toByteArray();

                return serializedObject;


Then it goes all the way to the client...

Client-side :

Code: [Select]

                Object3D objLoader = Loader.loadSerializedObject(new ByteArrayInputStream(serializedObject));
                _world.addObject(objLoader);


Can't see what I've done wrong...

Thanks by advance for the help.
