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.

CheckInterfaceSupport and EnumAdapters question

1 post in this topic

Hey, i solved some exersises when i noticed something strange

My code is:

the strange thing is, that the checkinterface support tells me, that my adapter is not 3d11 compatible (but it is) and then it also shows me a second adapter(at the end; but i have just one video card in my computer). the output enumeration is right, because i have 2 screens on my video card, but the second adapter really seems strange. i thought that it could maybe be my onboard hd3000 or so, but woulnt it also has a output?
hope u can help me with the questions

regards helgon

edit: and i dont know why i get the two exeptions, maybe someone else knows

[CODE]
IDXGIDevice* dxgiDevice = 0;
HR(md3dDevice->QueryInterface(__uuidof(IDXGIDevice), (void**)&dxgiDevice));

IDXGIAdapter* dxgiAdapter = 0;
HR(dxgiDevice->GetParent(__uuidof(IDXGIAdapter), (void**)&dxgiAdapter));
IDXGIFactory* dxgiFactory = 0;
HR(dxgiAdapter->GetParent(__uuidof(IDXGIFactory), (void**)&dxgiFactory));

IDXGIAdapter* pAdapter;
IDXGIOutput* pOutput;

DXGI_FORMAT format = DXGI_FORMAT_R8G8B8A8_UNORM;
UINT flags = DXGI_ENUM_MODES_INTERLACED;

std::wostringstream wos;
int check = 0;

for(UINT i = 0; dxgiFactory->EnumAdapters(i, &pAdapter) != DXGI_ERROR_NOT_FOUND; ++i) // anzahl der grafikkarten
{
LARGE_INTEGER version;
if(pAdapter->CheckInterfaceSupport(__uuidof(ID3D11Device), &version) == S_OK)
check = 1;

wos << "Adapter: " << i+1 << " (Videco Card) | " << "Adapter ID3D11Device Support: " << check << "\n";
for(UINT j = 0; pAdapter->EnumOutputs(j, &pOutput) != DXGI_ERROR_NOT_FOUND; ++j)
{
UINT num = 0;
pOutput->GetDisplayModeList(format, flags, &num, 0);
DXGI_MODE_DESC* pDescs = new DXGI_MODE_DESC[num];
pOutput->GetDisplayModeList(format, flags, &num, pDescs);
for(int k = 0; k < num; ++k)
wos << " Width: " << pDescs[k].Width << " Height: " << pDescs[k].Height << " Refresh Rate: " << pDescs[k].RefreshRate.Denominator << "/" << pDescs[k].RefreshRate.Numerator << "\n";

wos <<"EnumOutput\n";
}
}
OutputDebugString(wos.str().c_str());
wos.clear();
