      Download the Game Design and Indie Game Marketing Freebook   07/19/17

      GameDev.net and CRC Press have teamed up to bring a free ebook of content curated from top titles published by CRC Press. The freebook, Practices of Game Design & Indie Game Marketing, includes chapters from The Art of Game Design: A Book of Lenses, A Practical Guide to Indie Game Marketing, and An Architectural Approach to Level Design. 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.

Triangle not visible but background colour does render

1 post in this topic



I've finally decided to do the big step towards D3D11 from D3D9 and whoah it's a lot more overwhelming indeed.

I was a bit shocked to hear that D3DX was deprecated so decided to directly learn it the right (and hard) way without it.

Unfortunately every tutorial available, including the excellent Rastertek ones, seems to still use D3DX rather than DirectXmath.

I wanted to give it a try updating their tutorial to one that wouldn't require D3DX, even for compiling shaders and loading textures.

After battling with compilation errors the whole weekend I managed to finally compile without errors or warnings but.... Big disappointment.... It doesn't work when I run it. I can see the coloured background being cleared (set it to red on purpose as I wasn't sure the original black was the clear colour or just a fullscreen of plain nothingness lol. The triangle however isn't being rendered.

Very often beginners have problems with backface culling settings, or plain wrong transformations etc but this is from an existing tutorial that is known to work...


Here is what I did.

I replaced every D3DX type (e.g. D3DMATRIX, D3DVECTOR4, etc) with a new DirectXmath type (XMMATRIX,...)

I replaced the utility functions (D3DXMatrixRotateY,...) with equivalent XM functions too and adapted the parameters or other peculiarities that changed.

I removed runtime shader compilation (D3DXCompileFromFile) and instead embedded compiled shader files (*.cso) into the exe by using the resource compiler. Visual Studio 2012 itself uses FXC.EXE to compile the shaders along with the project. Very elegant solution.

During runtime I use FindResource/LoadResource/LockResource to get a pointer that CreateVertex/PixelShader can use.

I tried debugging extensively and all the pointers are being allocated and buffers created successfully so I assume it works.


One issue I had earlier was alignment errors on XM types and apparently compiling as x64 (which ultimately is also what everyone will have to do anyway in a near future) solved it. However, could it be that some variable size somewhere would need to be updated to a size_t or whatever to solve my problem? Or is it something else? I really can't find it which is why I decided to post my source here (well it's Rastertek's source with my updates)

If I can get this to work I might create an online tutorial as well and will credit whoever helped me here. Thanks.


EDIT: Before" RARing" the project to upoad it here I introduced a careless mistake due to which you probably got resource compiler errors... colorv.cso not found etc

I assumed I couldn't know if you'll compile under debug or release so attempted conditional compiling but it appears that #ifdef Debug or _Debug doesn't work at all at least on my system. To add insult to injury I misspelled a directory name (Debuge). 

If you compile under debug update the resource file to



#define RT_RCDATA 10
1000 RT_RCDATA "..\\x64\\Debug\\colorv.cso"
1001 RT_RCDATA "..\\x64\\Debug\\colorp.cso"
otherwise replace the directory names (Debug) by Release. It should compile now. (but it's not the fix for the original problem...)
Since the whole point is to find the error I suppose it's better to compile under Debug anyway.

OK don't bother. I solved it myself.


It was again a careless mistake of the kind that happens when you use copy/paste to avoid typing too much.

Somewhere in the code I had these lines:



xmpos = DirectX::XMLoadFloat3(&position);
    xmla = DirectX::XMLoadFloat3(&lookAt);
    xmup = DirectX::XMLoadFloat3(&up);
but with &position 3 times.
Now it works perfectly.
