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. when using the debug mode the debugger and the program work without any problems. and since having worked on other issues the release mode also works as wanted^^ thanks for that hint :)
  2. that's what I thought as well   I actually am compiling in release mode, so that means I cannot take the debugger information for absolutely true? Then the error may be at a completely different location...
  3. I discovered this as the root of my runtime crash. when trying to create a fullscreen display with e.g. 18361474x18361474 px it simply does nothing. So I debugged the program step by step and tried to change the values of width and height on runtime inside the debugger. When changing one of the two the other changes simultanously and so i found out using the debugger they have the same address in the stackframe of the function init_system(int, int).  And my question is: why?!?! that's simply not possible So my two problems are: 1. undetermined value of width and height 2. same address in memory
  4. hey everyone,  I have encountered a quite strange error. I have been working on my first little rpg and had never a problem with this function before but since having made several changes in other positions my args width and height in init_system(int, int) are not defined correctly (having undetermined values) and also have the same address in memory-.-   EDIT: I'm using MS VC++ 2010 and ALLEGRO 5.0.8 for my program.    Here the main file, other files may follow as necessary: #include <cstdio> #include <cstdlib> #include <cstring> #include <allegro5/allegro.h> #include <allegro5/allegro_native_dialog.h> #include <allegro5\allegro_image.h> #include <string> #include <vector> #include <algorithm> #include <fstream> #include "GraphicsLibrary.h" #include "Tile.h" #include "Player.h" using namespace std; #define FPS 60 int init_system(int, int); void tidy_up(); void drawScene(); void check_key(int); void proceed_key(); ALLEGRO_DISPLAY *display = NULL; ALLEGRO_EVENT_QUEUE *event_queue = NULL; ALLEGRO_TIMER *timer = NULL; bool keys[ALLEGRO_KEY_MAX]; Tile *currentRegion; Player *player; const int SCREEN_WIDTH = 1920; const int SCREEN_HEIGHT = 1080; int main(int argc, char *argv[]) { bool redraw = true; if (init_system(1920, 1080) == -1){ system("pause"); return -1; } while(1){ ALLEGRO_EVENT ev; al_wait_for_event(event_queue, &ev); if (ev.type == ALLEGRO_EVENT_TIMER){ redraw = true; } else if (ev.type == ALLEGRO_EVENT_DISPLAY_CLOSE){ break; } else if (ev.type == ALLEGRO_EVENT_KEY_DOWN){ check_key(ev.keyboard.keycode); } if (redraw && al_is_event_queue_empty(event_queue)){ redraw = false; drawScene(); al_flip_display(); } proceed_key(); al_rest(0.01); } tidy_up(); } int init_system(int width, int height){ if(!al_init()) { fprintf(stderr, "failed to initialize allegro!\n"); return -1; } if (!al_install_keyboard()){ fprintf(stderr, "failed to initialize the keyboard!\n"); return -1; } if (al_show_native_message_box(display, "3DPogramming", "Fullscreen", "Do you want to launch in fullscreen mode?", NULL, ALLEGRO_MESSAGEBOX_YES_NO) == 1) al_set_new_display_flags(ALLEGRO_FULLSCREEN); display = al_create_display(width, height); if(!display) { fprintf(stderr, "failed to create display!\n"); return -1; } event_queue = al_create_event_queue(); if (!event_queue){ fprintf(stderr, "failed to create event queue!\n"); al_destroy_display(display); return -1; } timer = al_create_timer(1.0 / FPS); if (!timer){ fprintf(stderr, "failed to create timer!\n"); al_destroy_display(display); al_destroy_event_queue(event_queue); } if (!al_init_image_addon()){ fprintf(stderr, "failed to init image addon!\n"); al_destroy_display(display); al_destroy_event_queue(event_queue); al_destroy_timer(timer); } al_register_event_source(event_queue, al_get_display_event_source(display)); al_register_event_source(event_queue, al_get_timer_event_source(timer)); al_register_event_source(event_queue, al_get_keyboard_event_source()); al_start_timer(timer); GraphicsLibrary::create(); currentRegion = new CapitalCity(); player = new Player(); return 0; } void tidy_up(){ al_destroy_timer(timer); al_destroy_display(display); al_destroy_event_queue(event_queue); al_shutdown_image_addon(); exit(0); } void drawScene(){ currentRegion->drawGround(player->getX(), player->getY()); player->draw(SCREEN_WIDTH / 2, SCREEN_HEIGHT / 2); } void check_key(int kc){ keys[kc] = true; return; } void proceed_key(){ if (keys[ALLEGRO_KEY_ESCAPE]){ keys[ALLEGRO_KEY_ESCAPE] = false; tidy_up(); } }
