The GameDev.net FreeBook is relevant to game designers, developers, and those interested in learning more about the challenges in game development. We know game development can be a tough discipline and business, so we picked several chapters from CRC Press titles that we thought would be of interest to you, the GameDev.net audience, in your journey to design, develop, and market your next game. The free ebook is available through CRC Press by clicking here. 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.

Overlay Demo

5 posts in this topic

I have been testing out your overlay desktop demo, and find it very well put together. I do have a simple question I hope. What would it take to make a directx or opengl version of this code to display a simple rotating box instead of the static on the screen?

What would be different from your normal DirectX or OpenGL program is that you need to copy the rendered scene to the overlay surface. This would require a lock on the render target, a slow video-to-system memory read, a conversion to the pixel format of the overlay surface (often one of the YUV), then a copy to the surface. Of course you would have to set up DirectX/OpenGL to render to an offscreen buffer without affecting current desktop.

Well dispite the resource hog it might be.
I would love to learn how you could do it.

Now forgive me for the newbee question on this, but maybe just a simple code exmaple of how to have the overlay demo load or display a simple box or even a image.

The static is great, but attempts to have it do a simple task of displaying a square or just a image instead of the static has failed.

Would anyone be willing to create a snippet to show me how it would be done?

P.S.
You know you have the only working exmaple of this on the net I have seen...

I would love to create a sample that does that, but I'm hard pressed finding time to work on AngelScript, so I'm afraid that you'll have to turn to someone else for that.

I will still be available for answering questions though.

To have more people regarding your question I think you should post in the DirectX forum.

I understand.
The basic file I wanted to try to incorprate was a very basic direct3d code at
http://www.cplusplus.com/src/direct3d.zip

The replies in the other forums I have gotten were "Just use active desktop"
But that just does not work for doing this in a direct 3d or direct draw enviorment.

What are you planning to do with the program? If you're doing it just for fun I'd say go right ahead. But if you want to learn how to do it order to something special with afterwards you might want to reconsider. You'll soon find out that overlay surfaces and the way they work are widely different from card vendor to card vendor. Some vendors may not even support overlay surfaces at all, others may not support destination color keying, etc.
