      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.

Loading shaders in D3D11

6 posts in this topic

Shader loading code is as follows:
[code]bool QuantumGameEngine::QuantumGraphics::CVertexShader::CompileShaderFromFile(LPCWSTR pSrcFile,
D3D10_SHADER_MACRO* pDefines,
LPD3D10INCLUDE pInclude,
LPCSTR pFunctionName,
LPCSTR pProfile,
UINT Flags1,
UINT Flags2,
ID3DX11ThreadPump* pPump){
//Compile our shader
if(FAILED(D3DX11CompileFromFileW(pSrcFile, pDefines, pInclude, pFunctionName, pProfile, Flags1, Flags2, pPump, &this->pShaderBlob, &this->pErrors, NULL))){
this->log(LEVEL_ERROR, "Failed to compile shaders");
MessageBox(NULL, reinterpret_cast<LPCWSTR>(this->pShaderBlob->GetBufferPointer()), L"FAIL", MB_OK);
} else {
MessageBox(NULL, L"FAIL", L"FAIL", MB_OK);
return false;
//Turn the blob into a shader
if(FAILED(this->pGC->pDevice->CreateVertexShader(this->pShaderBlob->GetBufferPointer(), this->pShaderBlob->GetBufferSize(), NULL, &this->pVertexShader))){
this->log(LEVEL_ERROR, "Failed to turn blob into shader object");
return false;
//Release the blob because we don't need it
this->pShaderBlob = nullptr;
//Release the errors
this->pErrors = nullptr;
return true;

Code that is used to call shader loading code:

[code]if(!this->pVS->CompileShaderFromFile(L"Shaders\\shaders.hlsl", NULL, NULL, "VertexShader", "vs_5_0", NULL, NULL, NULL)){
this->log(LEVEL_ERROR, "Failed to compile vertex shader");
return false;
if(!this->pPS->CompileShaderFromFile(L"Shaders\\shaders.hlsl", NULL, NULL, "PixelShader", "ps_5_0", NULL, NULL, NULL)){
this->log(LEVEL_ERROR, "Failed to compile pixel shader");
return false;

The call always returns with D3DX11CompileFromFileW failing and the shader error blob to be null. I never had any troubles with compiling shaders in DX9 and DX10...

EDIT: Here is shader code:
[code]struct VIn {
float4 position : POSITION;
float4 color : COLOR;
struct VOut {
float4 position : SV_POSITION;
float4 color : COLOR;
VOut VertexShader(VIn in){
VOut out;
out.position = in.position;
out.color = in.color;
return out;
float4 PixelShader(VOut in) : SV_TARGET {
return in.color;

Oops... I overlooked that.

EDIT: By setting it to pErrors, I get this error from the compile function:
[spoiler]Error message: C:\Important Stuff\Quantum Game Engine\Quantum Game Engine\StemVGC\Shaders\shaders.hlsl(11,6): error X3000: syntax error: unexpected token 'VertexShader'[/spoiler]

Problem solved... It seems as if you cannot name things in or out or VertexShader or PixelShader.

There's always the MSDN documentation available on [url="http://msdn.microsoft.com/en-us/library/windows/desktop/bb509561(v=vs.85).aspx"]Microsoft's website[/url] and/or your local DXSDK installation. The only thing it doesn't go over in extreme depth is optimization, and this is mainly because the specific method(s) are going to be different every card generation and frequently can contradict best practices for GPUs designed by competing IHVs. Textbook example of the latter is the old ATi/AMD vector-based ALU (doing things on single floats at a time is wasteful, though not necessarily slower per se) vs. the nVidia superscalar architecture, but I guess the new Radeon 7000s are actually moving over.

      I have a surface mesh and I want to use a cone to cut a hole on the surface mesh.
      Anybody know a fast method to calculate the intersected boundary of these two geometries?

      Hi, I tried searching for this but either I failed or couldn't find anything. I know there's D11/D12 interop and there are extensions for GL/D11 (though not very efficient). I was wondering if there's any Vulkan/D11 or Vulkan/D12 interop?

      Hi Guys,
      I am just wondering if it is possible to acquire the address of the backbuffer if an API (based on DX11) only exposes the 'device' and 'context' pointers?
      Any advice would be greatly appreciated

      bool InitDirect3D::Init() { if (!D3DApp::Init()) { return false; } //Additional Initialization //Disable Alt+Enter Fullscreen Toggle shortkey IDXGIFactory* factory; CreateDXGIFactory(__uuidof(IDXGIFactory), reinterpret_cast<void**>(&factory)); factory->MakeWindowAssociation(mhWindow, DXGI_MWA_NO_WINDOW_CHANGES); factory->Release(); return true; }  
      As stated on the title and displayed on the code above, regardless of it Alt+Enter still takes effect...
      I recall something from the book during the swapChain creation, where in order to create it one has to use the same factory used to create the ID3D11Device, therefore I tested and indeed using that same factory indeed it work.
      How is that one particular factory related to my window and how come the MakeWindowAssociation won't take effect with a newly created factory?
      Also what's even the point of being able to create this Factories if they won't work,?(except from that one associated with the ID3D11Device)

      Can anyone recommend a wrapper for Direct3D 11 that is similarly simple to use as SFML? I don't need all the image formats etc. BUT I want a simple way to open a window, allocate a texture, buffer, shader.
