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.

Segmentation fault in call to SDL_Quit

0 posts in this topic

I noticed it just recently, as I've been writing quite a bit without debugging. What is weird is that it didn't use to happen before (or maybe I just never noticed? But it seems unlikely...). So after hours of trying to see if I screwed up somewhere I decided to make a simple test program
[source lang="cpp"]#include <SDL.h>
#include <iostream>

#undef main // To use standard output

int main ( int argc, char** argv )
{
if(SDL_Init(SDL_INIT_VIDEO) < 0)
{
std::cout << "Unable to init SDL: " << SDL_GetError();
return 1;
}
SDL_Surface* screen = SDL_SetVideoMode(640, 480, 32, SDL_HWSURFACE);
if (!screen )
{
std::cout << "Unable to set 640x480 video: " << SDL_GetError();
return 1;
}

SDL_Quit(); // Error here
return 0;
}[/source]
Running gdb from codeblocks shows me 4 sigsegv before the debugger shuts down. This is the call stack for the first one (in the others the addresses of unknow functions change). Sometimes it stops at EndTask and sometimes at lstrlenA
