      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.

Self-hosting the Epoch Compiler: Day Six

Tackling problems with a fresh mind makes a world of difference.

The first thing I needed to solve this morning was a miscompile involving constructors. Deeper investigation showed that sum-typed members were to blame. Thankfully, this bug had an easy repro, so I built out a test case and set out to fix it.

A couple of false starts later, things were looking solid.

At 11:51AM PST, the self-hosted compiler passed its first test in the compiler test suite.

It's now time to run the full battery of tests on the shiny new compiler, and see if it passes enough of them to warrant attempting a second-order self-host.

At 12:02PM PST, the self-hosted compiler finished its first complete run of the test suite. There are a few failures, mostly dealing with pattern matching, which has always been the most fragile bit of the language implementation. Some of the failures I'm going to ignore because none of the compiler implementations can pass those tests yet, so it isn't really concerning that the self-hosted one can't either.

I'm not quite ready to proclaim self-hosting a success. The test failures are worrisome, and I haven't done a second-order self-host test yet (where I feed the compiler into the self-hosted version of itself... is this getting confusing yet?).

However, this is a huge milestone. To make sure the implications are clear, this is what happened:

  • I wrote a compiler, in C++, which compiles the Epoch language
  • I wrote a compiler, in Epoch, which does the same thing, using the C++ version to boot-strap it
  • The Epoch implementation of the compiler can compile itself
  • This "self-hosted" version of the compiler is almost completely accurate and stable

    I still have just over two weeks of padding time before my self-imposed deadline for finishing this project. That should hopefully be plenty of room to solve the last few bugs and get this thing completely done.

    For now, though, it is time to celebrate!

Congrats! That is a very major milestone, and an incredibly heartening achievement to keep up the spirits for the bug fixing ahead.
