      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.

Hello, i'm trying to set up an development enviroment with VS2010 but when i'm trying to compile my SFML code(http://www.sfml-dev.org/tutorials/2.0/./start-vc.php) i toke this errors:

When you created the project, did you select "Console Application"? Because if you didn't (that is, if you chose "Windows Application"), the tutorial says:

If you chose to create a "Windows application" project, then the entry point of your code has to be the "WinMain" function instead of "main". Since it's Windows specific, and your code would therefore not compile on Linux or Mac OS X, SFML provides a way to keep a standard "main" entry point in this case: link your project to the sfml-main module ("sfml-main-d.lib" in Debug, "sfml-main.lib" in Release), the same way you linked sfml-graphics, sfml-window and sfml-system.

Then is better i create an console application? CLR Console Application at VS2010?

 

Avoid CLR: CLR is Common Language Runtime, it is for coding .NET applications with C++.

Why not make an empty project, add main.cpp file with main method, and link your project with sfml-main.lib as it says in doc.

It doesn't really matter (console application vs windows application), so long as you follow the directions in the tutorial. An empty, plain console application will probably be a little bit simpler. And as Nercury says, stay away from the CLR (unless you know what it is and you know you want it).

Are you sure that your debug configuration (the one you're trying to build with right now) is linking to the debug version of the libraries (the ones ending with -d)?

 

Are you trying to statically link to SFML? If so, are you linking to the -s version of the libraries, and are you adding SFML_STATIC to your preprocessor definitions?

 

There are several ways to set up a project that uses SFML, and the tutorial talks about many of them. It would help a ton if you said exactly what you've done and how you've set up your project (maybe take screenshots of each configuration option). How are you linking? What are you linking to? What, if any, preprocessor definitions have you added? The devil is in the little details, and it without knowing the exact details we're just stuck here shooting in the dark.

Problem solved thanks Cornstalks and Nercury.

It would be great if you could share what you did to solve it for any future people who find this thread via Google.

I configured the Debug and Release to use the right lib's(sfml-xxx-d.lib for debug and sfml-xxx-s.lib for release) and then linked sfml-main.lib into linker settings. I added SFML_STATIC to Preprocessor.
