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. Because i'm writing mod to game, and everything i do, is in intercepted SwapBuffer. I do not load any libs.
  2. Found solution!   Problem was in init of glActiveTexture: PFNGLACTIVETEXTUREARBPROC pglActiveTexture = NULL; #define glActiveTexture pglActiveTexture; pglActiveTexture = (PFNGLACTIVETEXTUREPROC) wglGetProcAddress("glActiveTextureARB"); For some reason when i replace: glActiveTexture(GL_TEXTURE1);  with pglActiveTexture(GL_TEXTURE1); it start working.
  3. Hi I'm trying to pass 2 textures to fragment shader. But in shader only one texture is avaible.   I found that problem is in glActiveTexture.   After call with any args, like  glActiveTexture(GL_TEXTURE1), glActiveTexture(GL_TEXTURE2) .... i alway end in texture unit 0 here is part of code: glActiveTexture(GL_TEXTURE0); // debug GLenum e = glGetError(); // e = 0 GLint nn; glGetIntegerv(GL_ACTIVE_TEXTURE, &nn); // nn = GL_ACTIVE_TEXTURE = GL_TEXTURE0 glBindTexture(GL_TEXTURE_2D, leftEyeTextureHandle); glActiveTexture(GL_TEXTURE1); // !!! <- it does not work //debug GLenum e = glGetError(); // e = 0 GLint nn; glGetIntegerv(GL_ACTIVE_TEXTURE, &nn); // nn = GL_ACTIVE_TEXTURE = GL_TEXTURE0 !!!!!! glBindTexture(GL_TEXTURE_2D, rightEyeTextureHandle); I already cheacked: - GL_EXTENSIONS for GL_ARB_multitexture - tested "clean" example for multitexturing program and it work on same computer (GL_ACTIVE_TEXTURE gives GL_TEXTURE1 ...after glActiveTexture(GL_TEXTURE1)); - glActiveTextureARB - GL_MAX_TEXTURE_IMAGE_UNITS = 20 - GL_MAX_TEXTURE_UNITS = 4 - tests on other computers (gfx ati / nvidia)   Problem is in opengl state but i can't figure where is problem. Is there any "switch" to turn off multitexturing ?    fragment program: #version 150 uniform sampler2D left; uniform sampler2D right; in vec2 UV; out vec3 color; void main(){ if (mod(trunc(gl_FragCoord.x), 2.0) < 0.5) { color = texture(left, UV); } else { color = texture(right, UV); } }
