Now release it somewhere outside of USA, like England for example, and then I'll be impressed.

Very impressive.

I think I have this figured out. Assuming a camera transformation matrix that is calculated as: transform = Matrix.CreateScale(new Vector3((scale * scale * scale), (scale * scale * scale), 0))                 * ...

I've tried to work this out myself for a number of hours now and can't get it to work either. Does anybody know how to do this?

You could also try something like: enum Direction      {      NORTH,      SOUTH,  ...

Have you written a ContentWriter class for your new Attributes class?

That works great, thanks again.Additional question, is the Queue collection type also supported, or would I have to enqueue all the items from a List<> ?

Thanks for the quick reply Shawn, I'll give that a go.

Thanks to Nick's excellent article I can use a custom content reader/writer to load class types at run-time successfully.However, where I am now getting stuck is where the class being imported has other user-defined classes within it, or indeed Lists of user-defined classes.E.g. Public ClassA{ public int Foo; public List<ClassB> ...

Would be useful to see how you did this.Not sure how useful this would be for using textures containing multiple images (spritesheets for example), as you would be loading (and storing) up front a lot of data. Some number crunching on these cases would also be nice to see.
