      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.

Is there any way to test multi-player via tcp/ip with only one comp. Like could i start one game as the server then start another game as the client and tell the client to connect to my own IP address ? "Now go away or I shall taunt you a second time" - Monty Python and the Holy Grail

You can set up your server on your machine and then tell your client to connect to "localhost", that''s how I test a lot of my code when I''m just starting out. It also helps you make sure your code IS working, and packet loss is not to blame for something going wrong(of course you need to correct for things like that later, but it helps verify your initial work).

I''ve never used direct play. I prefer sockets myself, and if you are interested in portability(to say Linux) sockets are the way to go(almost every platform with networking supports sockets style access).


If you do use sockets, you need to write a layer on top of it to provide additional functionality(this is similiar in purpose to what DirectPlay does although your implementation will probably vary).


I have a library I wrote for sockets(works on both *nix and Windows) it supports a message passing style of connection. A client connects to a server and gets a message queque, the server is sent a message in its message queque. The server can create additional named message queques on the client. A "message" in this case is a message number(int), and an array of bytes(whose interpretation is up to you). Its a fairly simple abstraction, but it makes programming a client/server app pretty simple. It uses lots of threads for scalable performance issues and to make up for differences in the Windows and BSD style sockets handle asynchronous I/O. If you''re interested in talking further, or want to look at some of my code, I''ll be glad to help.

If you could mail me your code and let me have a look, it would be greatly apprecieated..........I was thinking of doing it that way by using sockets and just writing my own functions using sockets to do what I want.......but I am not real familiar with sockets......although I do have this programming book but it doesnt go into much detail about networking or sockets.......
I could look over your code and it would help me to learn it

what would be easier to woirk with ?
Direct Play or use windows sockets directly ?



Personal choice, the general side tends to lean toward sockets, but I would guess that this is primarily because of the lack of tutorials on directplay.

Once you get past dplay initialization troubles it''s easy sailing.
