The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games. It provides practical instruction on creating world-class games that will be played again and again. View it here. A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games. With special focus on those developers with small budgets and limited staff and resources, this book is packed with tangible recommendations and techniques that you can put to use immediately. As a seasoned professional of the indie game arena, author Joel Dreskin gives you insight into practical, real-world experiences of marketing numerous successful games and also provides stories of the failures. View it here. An Architectural Approach to Level Design This is one of the first books to integrate architectural and spatial design theory with the field of level design. The book presents architectural techniques and theories for level designers to use in their own work. It connects architecture and level design in different ways that address the practical elements of how designers construct space and the experiential elements of how and why humans interact with this space. Throughout the text, readers learn skills for spatial layout, evoking emotion through gamespaces, and creating better levels through architectural theory. View it here.

Garbled surface

I could try your code on my machine and see what I get if you would like. And I could take a look at your code too if you wanted.

Aldacron,
This may be unrelated, but with the release of Ultima IX and the new TNT drivers, Ultima IX was broke--- they have since released a patch. Something may have changed in the drivers...

One thing to check, if you're using 16-bit color, is the pixel format. Atleast, double check that.

Any DirectXperts out there know what could cause a DX backbuffer surface to be filled with garbage? This whole problem started when I downloaded Nvidia's latest Riva TNT reference drivers (Detenator 3.53 if I remember correctly). After that none of my compiled code worked. I kept getting the DDERR_SURFACELOST return when trying to lock the backbuffer. Restoring didn't help either. I have since went to the extreme of formatting the harddrive and reinstalling Windows 95 with the factory drivers for my Creative Graphics Blaster 16MB Riva TNT card. Now the surface locks fine but when I call flip from the primary, I get a screen full of junk. Kind of reminds me of DOS when forgetting to clear video memory out.

I have pored through my code again and again. I have compiled other code samples and they work just fine. So that tells me it's a problem with my code, which worked fine before I ever downloaded those drivers. This whole mess has got me banging my head against the wall (it's either that or my monitor).
Replacing the calls to the back buffer with the primary surface displays just fine. Only the backbuffer is grabled.

I've ruled out the factory drivers because the code I compiled from other people (books, net) worked fine. I've cut and pastted into my code and it still didn't work! All the commercial products I have that use DX work fine as well. Any one have any ideas as to what could cause this? I'm using DX 7 BTW.
