      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.

  1. Huge thanks hplus0603, your idea to check the throughput was spot on. Also once more experienced how important proper version control is. The problem was on the client side after all, the used client version there had a bandwidth limit specified in enet_host_create(). Getting rid of that limitation fixed the problem.   Knowing how to debug is definitely a must, but usually I manage with alternative debug methods instead of going step by step. I will dive into multithreaded debuging next tough but after being done with thesis. In this case the program is just a prototype/case study for an approach, so the code itself could be improved quite a bit by someone more experienced. First time threading, working with openGL, etc. Once again thanks a lot! BR, Frable
  2. Thanks hplus0603, will try to analyze the throughput and try to get some answers from that. I hope to find the solution without step by step debugging, as it is my first multithreaded program and various libraries apart from eNet are used. Last time I tried to debug it in qtcreator I got more confused than in the begining.  Will report back after taking a more detailed look at the transfered data amount. 
  3. Hi,  I have been toying around with eNet for my bachelor thesis and everything seemed to work alright, till I started to dump simulated data continuously onto the eNet connection. After a short period of time the performance drops down immensly.  Situation elaboration: I have a client send interaction data via eNet to a server program, where that interaction is processed and triggers a video frame as response, also sent via UDP but not via eNet. In the beginning I get ~17 fps as a response, but starting with frame 30-50 (it variates) it drops down to ~5 fps, the increasing delay being in the enet server. So it would seem that some kind of buffer/cache has been filled up and thus slows down. Trying it on manual interactions the same happens, fps drops down after some time of continuous interactions and is back to normal if you stop interacting for a while.  The weird things that, in my opinion, doesn't fit the picture, is the fact that I normaly send my interactions in a 30 ms interval, if I change that interval to 1 ms, the framerate doesn't drop at all. Altough, the interactions (same amount) are dumped onto the stream in aprox. 1 seconds time, buffered on the server and frame responses arrive for quite some time afterwards.  What I did notice, is that when the fps drop occurs, my buffercount drops down to 1, and in the case of 1ms interval for interactions the buffer count is more or less constantly 2.  Another idea, could the cause be the fact that I have server and client running on the same pc to avoid network delay/packet loss/corruption? So the problem being related to multiple network adapter acceses simultaniously? Server program is multithreaded.  Any ideas on how to battle this fps drop? Had no luck finding anything usefull in the documentation or forums so far. Working on Linux Ubuntu and CPU and Memory itself doesn't seem to be the hog.  Thanks,  Frable
