      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.

  1. I followed what @Krypt0n said and that solved the problem. Here is my sampler now: D3D11_SAMPLER_DESC samplerDesc; ZeroMemory(&samplerDesc, sizeof(samplerDesc)); samplerDesc.Filter = D3D11_FILTER_ANISOTROPIC; samplerDesc.AddressU = D3D11_TEXTURE_ADDRESS_WRAP; samplerDesc.AddressV = D3D11_TEXTURE_ADDRESS_WRAP; samplerDesc.AddressW = D3D11_TEXTURE_ADDRESS_WRAP; samplerDesc.MaxLOD = D3D11_FLOAT32_MAX; samplerDesc.MaxAnisotropy = 16; And some images:   I truly appreciate the help. Thanks :)
  2. ok, I will try this tonight.   Yes it does. I'm using CreateDDSTextureFromFile function from DirectxTex.   ---   Thank you all for the replies. I will give a feedback as soon as possible.
  3. I have a grid terrain with a brick texture tilled over it, but I'm getting some Moiré patterns when moving the camera around:     Here is the sampler desc: D3D11_SAMPLER_DESC samplerDesc = {}; samplerDesc.Filter = D3D11_FILTER_ANISOTROPIC; samplerDesc.AddressU = D3D11_TEXTURE_ADDRESS_WRAP; samplerDesc.AddressV = D3D11_TEXTURE_ADDRESS_WRAP; samplerDesc.AddressW = D3D11_TEXTURE_ADDRESS_WRAP; samplerDesc.MaxAnisotropy = 8; The texture is a 512x512 .dds file with 10 mipmap levels created with nvidia texture tools on photoshop and it's tilled 64 times so that the bricks looks small. If I decrease the tilling number, the Moiré Effect decreases a little too. My guess is that I'm repeating the texture too much and therefore causing minification, but the mipmaps should handle this, right?
  4.   Make sure you are calling CreateWICTextureFromFile from the WICTextureLoader.h you have just created. I can't read your code right now, so here is an simplified example of how I call this function (note the DirectX namespace; TextureMgr is my class that holds this function; md3dDevice is a raw pointer to a ID3D11Device): #include "WICTextureLoader.h" ID3D11ShaderResourceView* TextureMgr::CreateTexture(std::wstring filename) { ID3D11ShaderResourceView* srv = 0; DirectX::CreateWICTextureFromFile(md3dDevice, filename.c_str(), nullptr, &srv); return srv; }
  5. Actually, DirectXTK has DDSTextureLoader and WICTextureLoader. Again, it is possible to rip these files to your own project.
  6. Hello Meho, maybe the ID3D11DeviceContext *pContext parameter is missing on the call? Also, I recommend you to use DirectX Tool Kit for a more "modern" texture loading, you can get more info here and here is the source (you can copy the .h and .cpp files to your project, there is no need to use the entire DirectXTK library).
  7. Hello everyone, I'm getting an error when running "Init Direct3D" from Frank Luna's Directx 10 book (CH 4): [img]http://img820.imageshack.us/img820/6439/d3d10error.png[/img] I just downloaded the code from [url="http://www.d3dcoder.net/Data/Book3/PartII.zip"]http://www.d3dcoder....ook3/PartII.zip[/url], it compiles without errors, but when I start debuging, this error appears [img]http://public.gamedev.net//public/style_emoticons/default/wacko.png[/img] . What I'm doing wrong? System info: win8 x64 gtx 460 dxsdk jun10 (debug layer enabled) ps: I can post the code here, but it's a bit long, so if you guys prefer this way, just let me know. Thank you.
  8. so, in an abstract way, it works like this (?): int array[[color=#a52a2a]5[/color]][[color=#006400]5[/color]]; [color=#a52a2a]0x0001[/color] [color=#006400] 0x0002[/color] [color=#006400] 0x0003[/color] [color=#006400] 0x0004[/color] [color=#006400] 0x0005[/color] [color=#006400] 0x0006[/color] [color=#a52a2a]0x0007[/color] [color=#006400] 0x0008[/color] [color=#006400] 0x0009[/color] [color=#006400] 0x000A[/color] [color=#006400] 0x000B[/color] [color=#006400] 0x000C[/color] [color=#a52a2a]0x000D[/color] [color=#006400]...[/color] [CODE] int* value = array+1..5 //for looking up a column value from line 1 int* value = array+6+1..5 //for looking up a column value from line 2 //and so on. [/CODE] ? thank you.
  9. hello everyone, i have a question about the c++ language, so i will start by a example: [CODE]void do_something(int v[]);[/CODE] why i don't need to specify the vector size in the function parameter? how does the compiler knows the size of it? (i think that it takes from the function call... right?) another example: [CODE]void do_something2(int v[][5]);[/CODE] ok ok, i don't have to specify the lines size, but i have to specify the columns size... if the compiler can "take automatically" the lines size (as in the first example), why it don't take the columns too? (sorry for the bad english, it's not my native language) thank you.

    [quote name='jouley' timestamp='1344195027' post='4966442'] [quote name='lucaswrk' timestamp='1344194233' post='4966437'] glClearColor(rand()%256, rand()%256, rand()%256, 1.0); [/quote] Your alpha value is 1.0. You probably meant 255 [img]http://public.gamedev.net//public/style_emoticons/default/smile.png[/img]. Edit: It's also possible that glClearColor expects floats clamped to 1.0, in which case it's highly likely you're always getting white since [tt]rand()%256[/tt] will usually be nonzero. Try dividing the results of that calculation by 255.0f to find out. (Or check the documentation... either way, don't mix clamped floats and integer formats.) [/quote] yeah, that was the problem! x >= 1.0 will be the color max value, that's why my screen was getting white every time. Exactly as you said. heres the correct code (with jouley's hint), if someone is interested.. [CODE] float r = rand()%256 / 255.0f; float g = rand()%256 / 255.0f; float b = rand()%256 / 255.0f; glClearColor(r, g, b, 1.0); [/CODE] thank you @jouley!
  11. hello everyone, i'm new to opengl and im having trouble to generate glClearColor random values... if i set it manually, works well but with rand()%256 it not. Whats going on ? os: ubuntu 12.04 io/window library: sdl heres my code: [CODE] #include <iostream> #include "SDL/SDL.h" #include "SDL/SDL_opengl.h" #include <stdlib.h> #include <time.h> using namespace std; int main() { srand(time(NULL)); SDL_Init(SDL_INIT_EVERYTHING); SDL_GL_SetAttribute(SDL_GL_RED_SIZE, 8); SDL_GL_SetAttribute(SDL_GL_GREEN_SIZE, 8); SDL_GL_SetAttribute(SDL_GL_BLUE_SIZE, 8); SDL_GL_SetAttribute(SDL_GL_ALPHA_SIZE, 8); SDL_GL_SetAttribute(SDL_GL_BUFFER_SIZE, 32); SDL_GL_SetAttribute(SDL_GL_DEPTH_SIZE, 16); SDL_GL_SetAttribute(SDL_GL_DOUBLEBUFFER, 1); SDL_WM_SetCaption("Our first game", NULL); SDL_SetVideoMode(600, 400, 32, SDL_OPENGL); glClearColor(255,255,255,255); //rgba glViewport(0, 0, 600, 400); // top-left bottom-right viewport range glShadeModel(GL_SMOOTH); // gradient glMatrixMode(GL_PROJECTION); // 2d glLoadIdentity(); glDisable(GL_DEPTH_TEST); bool isRunning = true; SDL_Event event; while(isRunning) { while(SDL_PollEvent(&event)) { switch(event.type) { case SDL_QUIT: isRunning = false; break; } if(event.type == SDL_KEYUP && event.key.keysym.sym == SDLK_ESCAPE) { isRunning = false; break; } if(event.type == SDL_KEYUP && event.key.keysym.sym == SDLK_r) { glClearColor(rand()%256, rand()%256, rand()%256, 1.0); break; } } //rendering glClear(GL_COLOR_BUFFER_BIT); SDL_GL_SwapBuffers(); } SDL_Quit(); return 0; } [/CODE] thank you.
