      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.

AngelScript 2.26.2

8 posts in this topic

It appears that character literals are now treated as signed (most likely per rev 1600), but scriptstdstring addon's index operators still use uint8. This forces a rather awkward syntax needed for working with literals of high ASCII codes without getting any warnings:

somestring[5] == uint8('?');

I think character literals should stay unsigned, but in any case their sign should match that of the addon.

Actually, character literals are still unsigned. This was not changed when I changed integer numbers to be signed.

 

What settings do you have for the following engine properties?

 

asEP_SCRIPT_SCANNER

asEP_USE_CHARACTER_LITERALS

asEP_STRING_ENCODING

 

What is the compiler warning you get? And for what expression do you get them?

Indeed they are. I just realized that it is our preprocessor that converts the character literals into integers, as a normal step of preprocessing. We don't even have asEP_USE_CHARACTER_LITERALS enabled. Another false alarm!

Ah, you edited the message :)

 

So, your pre-processor is the one that treats the character literals as signed chars? Is this a home grown pre-processor?

It is an improved version of the good old preprocessor by Anthony Casteel (also known as Deyja), from sources dating back to 2005 or so. I was going to mention it in relation to the other topic: http://www.gamedev.net/topic/640629-cc-like-define-directive-patch-attached/

 

It is built over version 0.5 of that preprocessor. I couldn't find any newer version (if it ever existed), in fact I can't seem to find the original sources whatsoever, anywhere. In addition to the features from 0.5, our version includes:

- multiline macros,

- recursive macro expansion,

- token concatenation with ## operator,

- evaluation of constant expressions (somewhat incomplete),

- additional features for #pragmas,

- minor things such as #warning and #error,

- incidentally, character literals are now converted to unsigned integers.

 

It is still independent from AngelScritpt and is platform-agnostic, and features a working line number translation between sources and the preprocessed file. And it is still pretty lightweight.

 

I have hopes to release (or should I say re-release) it soon, although that's not entirely up to me. And following that, discuss a possibility of including it in AngelScript sdk in some way (probably as an addon).
