      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.

Golang Game Programming Question

3 posts in this topic

Recently I have considered using golang as the basis for a game runtime. I was tinkering with the idea of wrapping SFML into a Go library and linking in game modules written in GO.  I was wondering if anyone had any experience with golang and had any advice for me.

 

For example, is it a good idea to place the game loop on the C/C++ side, or keep it on the Go side?

 

I use <extern void go_func_name() __asm__ ("package_name.function_name");> as the basis for calling over into go. Are there more efficient ways of doing this? What if I do not know the name of the package/function at compile time?

Even if C++ will be a bit faster for runtime generated code, because compilers are more mature, and it has more features that are often the optimal way of doing them when you absolutely have to use them. (it was a conclusion of google when benchmarking different languages)

I would not use performance as a criterion to separate code into both languages.

if you want to make a game in Go, just do everything in GO, why not ? at least you have the advantage of having a very fast compilation, a clean grammar that allows inteli-sense-like tools to work as excpected (and not broken like with C++). this could reveal important for project dev speed.

Initially, I was using Lua (LuaJIT, and nginx/LuaJIT) for everything server-side, but was hitting way too many compatibility issues where 3rd party libraries weren't working with each other.

 

I switched to Go for the server-side, even including the webserver, and it is working like a charm.  The performance is extremely good (fairly close to C levels) but the big thing is productivity is high as it has all the newer language features and in general is well thought out.    Like any language, it has its nuances, and I'm still not really used to its different OO'ish mechanisms, but in general things "just work" including the easiest multitasking I've seen.  

  

While it doesn't have nearly the same depth of library as common languages like Java, Perl etc, I find that the few it has tend to be exactly the ones I need and are well thought out. Some of the most common ones (web serving, sockets, Templates) are built right into the main language library and are easy to use.

I want the game logic done with Go packages linked in after the fact, and the runtime will be partly C and Go. I am not certain how to do all of it in Go.  It seems some things are easier with C libs linked in.
