Query: NOT A GOOD BOOK FOR NEWBIES (OR PROS)!!!

This book doesn't teach directx very well at all. Which makes it a book for experienced programmers, but lacks advanced information for experienced programmers. I learned nothing about artificial intelligence, 3d anything, or even the slightest bit about directx. If you really want to get into directx, get "Inside DirectX" by the Microsoft Press. Let the professionals teach directx programming.
