      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. Hello guys, I'm trying to integrate SMAA T2X (in OpenGL) in my project.   I got the SMAA 1x working very fast. However, I'm struggling to make the SMAA T2X version to work.   I have a set of 2 framebuffers representing the "previous" and "current" neighbourhood blending pass, just like in the SMAA DX10 demo  (https://github.com/iryoku/smaa/tree/master/Demo/DX10). The documentation of the shader tells to render the geometry using subpixel jitters (https://github.com/iryoku/smaa/blob/master/SMAA.hlsl). For this, I create a jittering matrix which I apply in this way      MVP = Projection * View * Model * JitteringMatrix; glm::vec2 jitter = getJitter(); glm::mat4 jitter_mat = glm::translate(glm::mat4(), glm::vec3(2.0f * jitter.x / float(width_), 2.0f * jitter.y / float(height_), 0.0f)); the getJitter function returns the jittering depending on the current frame of SMAA glm::vec2 jitters[] = { glm::vec2(-0.25f, -0.25f), glm::vec2( 0.25f, 0.25f) }; return jitters[frame_index_]; However, the jittering matrix seems to be moving some geometry of my scene a little too much. Some objects start to shake after I apply this matrix. But this shouldn't happen since the jittering matrix should move the geometry less than a pixel (subpixel) so it shouldn't be noticeable. Here's a short video showing the problem. I don't really know if the jittering process is causing the problem or if I'm doing something wrong in another step. https://vid.me/uQq9   Thank you very much for your help!   EDIT: I think I solved the error. I should multiply the jittering matrix on the left side (JitteringMatrix * P * V * M); doing this solved the problem. However at low framerates the whole image starts to jitter (only a bit), is this normal?   
  2. Hello there, first of all, I'm not sure if my question fits in this forum, if not, feel free to move it and sorry about it   .   So I'm doing a "game engine" as a project for a subject in my career. The teacher said it would be nice to support forward and deferred rendering at the same time, similar to what Unity does.   My question is. How would achieve this to be scalable, to support any rendering path in the future without having to change anything of the previous code? My teacher named a thing called a "composer" but I'm not familiar with this, I searched a lot but didn't find anything.   I don't need example code, just an advice on how to structure the engine correctly.   Thank you, your help is very much appreciated
  3. [quote name='Washu' timestamp='1336253793' post='4937665'] You should be using, last I recall, the NIO sockets. [/quote] thank you very much, didn't know about this! [quote name='SimonForsman' timestamp='1336253844' post='4937666'] First of all, Transformice is not an MMO, (each game has a very low number of players so you don't need to deal with MMO scale networking for this type of game). What you should do is have one master server for the "lobby" and then run multiple game servers, They can but doesn't have to be on the same machine but needs different ports and should be handled by their own instance of the server application. Have the master server keep track of how many instances of the game server each node is running and launch new ones as needed on the least busy node, (You can have game servers report their nodes status to the master server for this purpose) For the game servers 1 or 2 threads are enough, (having one thread that only waits for new connections and one that runs the game can simplify things slightly) [/quote] I'm not sure if I understand your post. Do you mean that rather than spawning a new thread per client connected, I run some kind of game server node for handle the new client connected ? Or do you mean these game server nodes should be able to handle more than one client ? Because that is what really I was wondering. I can't figure out a way for handling multiple clients without spawning a new thread for each connection. Maybe I'm a little bad for these things [img]http://public.gamedev.net//public/style_emoticons/default/tongue.png[/img] also thank you very much for your answer too! Regards.
  4. hi [img]http://public.gamedev.net//public/style_emoticons/default/tongue.png[/img] first of all, this is my first post! second, i read the FAQ's, but my doubts are still there [img]http://public.gamedev.net//public/style_emoticons/default/sad.png[/img] So I'm programming a server for a multiplayer game in Java, but I don't know the proper way to handle the client connections. The game is like a tiny mmo inspired inspired by Transformice. For those who do not know, Transformice is a MMO flash and tcp based game. It has around 60.000 concurrent players / day average and I wonder how they handle this amount of connections. Right now, my server spawns a thread for every client connection and I read in the FAQ's this is not good but also I thought same before read it. So basically the question is, how i manage my server to keep as many client connections as hardware / network is capable to (Without spawning a new thread for each client connection because i think this is not suitable for a mmo game). As far as i know JVM can't handle that huge amount of threads, so this can't be the right way. also I'm such a noob in networking. I started to learn it few months ago. Someone gives me some light? Regards.
