      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.

libcliser: C++ library for creating multithreaded TCP servers

8 posts in this topic

Hi,

presenting my C++ library which offers a network layer for TCP server and manages network sockets in separate threads.

[url="http://code.google.com/p/cliser/"]libcliser[/url]

It has thin area of use but offers simple API.
The library is cross platform, tested to work under linux and Windows. Under Windows it was tested using MinGW compiler, but in theory should work with MSVC compiler too.
Any feedback is welcome.

Don't take this the wrong way, but I'd like to understand why you made this library, and made it public?
Specifically, I'd like you to answer these questions:

What's wrong with boost::asio?
What's wrong with SDL_net, or plib, or one of a zillion other "portability" network libraries?
Or RakNet, or Enet, or ACE, or ICE, or one of a zillion other higher-level networking libraries?
Why are you serving sockets in separate threads, when that's well known to be inefficient? (see the FAQ)

Your answer may be "because I wanted to learn networking for real," which is a fine motivation, but it's unlikely that someone's learning project can become a solid foundation for a distributed/networked application, so making it a public library seems weird in that case.

Well, it is better than nothing. I'm sure he had the best intentions.

Well, I think my library offers simpler API which allows faster start implementing the server logic instead of coping with sockets-shmockets and other stuff... At least that was my intention, to create a library which would hide all the networking layer.

Regarding serving sockets in separate threads... I'm serving a number of sockets in one thread, and there can be several such threads. So, it is not a one socket per one thread. This maybe not the most efficient approach but in my opinion it provides enough efficiency in majority of cases.

Anyway, thanks for the feedback, this is what I made this post for.

So, you still haven't answered the differentiation quesiton.


Why your library, instead of boost::ASIO, or any one of a zillion of other, high performance, robust, networking libraries?

I'm for being free to work on what you find interesting. One lib that you didn't mention is Poco. If he wants his library to do well though he'll eventually have to answer the questions you've posed. It is a tough space to break into.

I've analyzed the source code very shortly.
As it turns out, this is merely a slim layer over another library named ting that does all the actual work. In short, he's posted the equivalent of maybe a week or two of work (assuming he was unfamiliar with Ting and asynchronous design concepts to begin with), which is based on likely months or even years of other people's much more intensive work and knowledge.
