      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. Yes but I need a solution wich is compatible with GL 3 and higher
  2. This one also don't works. [Edit] Ok i see, at the top of the page they wrote that's incompatible with opengl 3+ I'll try it with shaders
  3. Hey, I'm new to OpenGL and 3D Game developement ( ~ 2months) I am creating a tiny 3D engine for education purposes - It was going on fine, but now I have problems with Multitexturing. I'v ripped a model from a game and converted it to wavefront .obj With just 1 texture it looks very nice but when I'm loading the second texture the problems start. The second texture has the same size as the first, but it has more alpha chanells because the second texture is just for some hairs and teeths. I've got some combinations of glTexEnv with GL_COMBINE etc. The first Texture replaced the second texture at the colored area and the transparent areas (of the second texture) where still there. But it should be the opposite, it should show me the RGB of the first texture at the transparent area of the second texture, and the second texture (hairs, teeths, cloths) should be drawn over the first texture. here is my rendering part of the texture : [CODE] if(obj.obj.texture_id.size() > 0)for(int text_id = 0;text_id < obj.obj.texture_id.size(); text_id++){ glActiveTexture(33984+text_id); // 33984 = GL_TEXTURE0 glEnable(GL_TEXTURE_2D); glBindTexture(GL_TEXTURE_2D, obj.obj.texture_id[text_id]); if(text_id==0){ // First texture glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_COMBINE); glTexEnvi(GL_TEXTURE_ENV, GL_SOURCE0_RGB, GL_TEXTURE); glTexEnvi(GL_TEXTURE_ENV, GL_COMBINE_RGB, GL_MODULATE); }else if(text_id==1){ // second texture glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_COMBINE); glTexEnvi(GL_TEXTURE_ENV, GL_SOURCE0_RGB, GL_PREVIOUS); glTexEnvi(GL_TEXTURE_ENV, GL_SOURCE1_RGB, GL_TEXTURE); glTexEnvi(GL_TEXTURE_ENV, GL_SOURCE0_ALPHA, GL_PREVIOUS); glTexEnvi(GL_TEXTURE_ENV, GL_SOURCE1_ALPHA, GL_TEXTURE); glTexEnvi(GL_TEXTURE_ENV, GL_OPERAND0_ALPHA, GL_SOURCE0_ALPHA); glTexEnvi(GL_TEXTURE_ENV, GL_OPERAND1_ALPHA, GL_SOURCE1_ALPHA); glTexEnvi(GL_TEXTURE_ENV, GL_COMBINE_RGB, GL_REPLACE); // To replace the Color of the first texture glTexEnvi(GL_TEXTURE_ENV, GL_COMBINE_ALPHA, GL_MODULATE); // To 'neutralize' the alpha channel } }[/CODE]
