      Download the Game Design and Indie Game Marketing Freebook   07/19/17

      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.

Errors in Unix to Windows conversion

3 posts in this topic

I'm trying to port an algoreithm from a unix program to something that will compile in visual studio. I've had to find and include a unistd.h a getopt.c and a stdint.h I found online. I'm still getting some errors that might be because of differences between systems.

1st error
[i]Error 4 error C2371: 'int8_t' : redefinition; different basic types c:\users\minion\documents\visual studio 2008\library\bam2bed\stdint.h 82 BAM2BED[/i]


[CODE]

#include <limits.h>

// For Visual Studio 6 in C++ mode and for many Visual Studio versions when
// compiling for ARM we should wrap <wchar.h> include with 'extern "C++" {}'
// or compiler give many errors like this:
// error C2733: second C linkage of overloaded function 'wmemchr' not allowed
#ifdef __cplusplus
extern "C" {
#endif
# include <wchar.h>
#ifdef __cplusplus
}
#endif

#ifndef _W64

# define _W64 __w64
# else

# endif
#endif


// 7.18.1 Integer types

// 7.18.1.1 Exact-width integer types

// Visual Studio 6 and Embedded Visual C++ 4 doesn't
// realize that, e.g. char has the same size as __int8
// so we give up on __intX for them.
#if (_MSC_VER < 1300)
typedef signed char int8_t;
typedef signed short int16_t;
typedef signed int int32_t;
typedef unsigned char uint8_t;
typedef unsigned short uint16_t;
typedef unsigned int uint32_t;
#else
typedef signed __int8 int8_t; //ERROR IS HERE
typedef signed __int16 int16_t;
typedef signed __int32 int32_t;

typedef unsigned __int16 uint16_t;
typedef unsigned __int32 uint32_t;
#endif
typedef signed __int64 int64_t;
typedef unsigned __int64 uint64_t;
[/CODE]


second error
[i]Error 5 error C2039: 'isdigit' : is not a member of 'std' c:\users\minion\documents\visual studio 2008\library\bam2bed\bedfile.h 336 BAM2BED[/i]

what might the fix be? Edited by jbadams

Likely the problem with error 1 is resultant from a different error elsewhere. The error message is pretty description, you're defining int8_t twice, probably with different types.

The second error is probably due to not including <cctype>. See [url="http://www.cplusplus.com/reference/clibrary/cctype/isdigit/"]http://www.cplusplus.com/reference/clibrary/cctype/isdigit/[/url]

I do see int8_t being defined twice once as a signed char and another as a signed int8 below. Is this the acutal mistake or is it allowable and there must be something else wrong? But as I got this code somewhere else I assumed that it was correct for unix

[CODE]#if (_MSC_VER < 1300)
typedef signed char int8_t;
typedef signed short int16_t;
typedef signed int int32_t;
typedef unsigned char uint8_t;
typedef unsigned short uint16_t;
typedef unsigned int uint32_t;
#else
typedef signed __int8 int8_t; //ERROR IS HERE[/CODE]

Due to the ifdef there, the line right below the _MSC_VER check and the line right below the #else are not going to both be compiled. One or the other will be.

You likely have another, seemingly unrelated definition of int8_t some additional place. VS is pretty good about finding these things, if you just ask it to find the definition of it.
