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.

For my project I''ve written data to a file, only containing numbers from 0 to 5 seperated by a space and I want to read all numbers in it and put it in an array. The text file contains 150 lines each with 150 numbers with a space between two numbers. Like this: 0 0 0 1 1 1 0 0 0 1 1 1 0 0 0 1 1 1 I want to read it and put it back into an integer array. Does someone know how, thanks. Jeroen "2COOL4-U" de Haas - DefenceAlliance Project Leader/Coder - TacticalOps Linux Beta Tester

this should work, its probably not the best method but should be ok to use...

    
void ReadData(char ReadDataFilename[20])
{
std::ifstream DATA(ReadDataFilename);
if(DATA)
{
for(int i=0; i<MAX_DATA; i++)
{
std::string data;
DATA >> Num[i];
}
}
else
{
cout<<"could not load data..."<<endl;
}
}


then in your main function call ReadData("filename.dat") (or whatever you called it)

if this is not the best way for the task, please tell me, as i use it often.

thanks

EDIT: if you want to put the data back into a 2d array: Num[x][y] (or whatever) just add another 'for' loop and so then you have:
  
for(int i=0; i<MAX_DATA_X; i++)
{
for(int o=0; o<MAX_DATA_Y; o++)
{
std::string data;
DATA >> Num[i][o];
}
}

that should work, probably wont... ho hum!
