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.

  1. Thank you very much for your reply, it is an N*N problem, it is not scalable so i think we have to modify the server structure, it will not re-stream to every client, it will create a message and send it to every user, this way the numer of sendTo calls(and bandwidth) will sacale more linearly and not exponentially, i think this will make the server much more responsive for 50k users , i am working on that idea now...
  2. Hi, I am new to gaming server development, i am currently starting a new server, my first one and a huge one I have allways programmed in C/C++, i come from embedded systems programming in pure C in the las year , now i have been told that developing that gaming server/framework will be much easier in C#, so I am in the way The gaming server goal is to be able to manage 50k clients using some normal hardware, core i7 4-8 cores, 12Gb of RAM ....etc... some good machine but not a NASA one I have made one layer that will accept and Log in gamers into the server using TCP, TCP will be used for login and some kind of ping with every user. This part seems to be working at the moment. I have a thread that is getting datagrams from udpInputSocket of the server, it will only take that datagrams from every user and delegate them to other stage that will process them in many stages/threads. Now what I am trying to do is just taking every datagram from every user (currently simulating 1k users) and then re-stream this packet to every user, the problem is that it is taking too long.... it is so so slow compared to the UDPReceiveThread..... The thing here is that the receive thread enqueues every message received and the "broadcaster" thread is taking every queued message and sending it to each of the 1k users, this seems a huge task as it is running so slowly, i just loop over every messange and the over ever client calling socket.SendTo(.........). The main question here is, am I doing it as it should be done? is it a matter of more "broadcaster threads" needed? or am I missing something like socket multicasting or broadcasting. I think I can´t broadcast or multicast becouse we are not aiming at LAN gaming rather than online internet gaming and i don´t know if in that scenario we can use that broadcast/multicast techniques. Any help or suggestions in my new challange?? Thank you very much to every body! PD: This would be the "broadcaster thread": [CODE] private void UDPBroadCastThread() { List<String> broadcastQueue = new List<string>(); ASCIIEncoding encoder = new ASCIIEncoding(); byte[] buffer; _udpSendSocket.SendTimeout = 1; //Miliseconds timeout while (true) { if (broadcastQueue.Count > 0) { for (int i = 0; i < broadcastQueue.Count; i++) // Loop through List of messages to broadcast { // Wait until it is safe to enter. _clientsListMutex.WaitOne(); for (int client = 0; client < _myClientsList.Count; client++) // Loop through every user { buffer = encoder.GetBytes(broadcastQueue[i]); int bytesSent = 0; bytesSent = _udpSendSocket.SendTo(buffer, broadcastQueue[i].Count(), 0, (EndPoint)_myClientsList[client]._clientUDPEndPoint); if (bytesSent != broadcastQueue[i].Count()) { Console.WriteLine("Error sending data: {0}", broadcastQueue[i]); } } // Release the Mutex. _clientsListMutex.ReleaseMutex(); } broadcastQueue.Clear(); } else { Thread.Sleep(10); // Wait until it is safe to enter. this._broadCastMutex.WaitOne(); broadcastQueue = (List<String>)this._newBroadcastQueue; this._newBroadcastQueue = new List<String>(); // Release the Mutex. _broadCastMutex.ReleaseMutex(); } } } [/CODE]
