      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.

Indexed property accessors and namespaces

2 posts in this topic

I have an array I would like to expose to Angelscript (using v2.25.2):
[source lang="cpp"]bool getTrigger(Word8 id) {
return triggers[id&31] == 1;
bool setTrigger(Word8 id, bool setTo) {
return (triggers[id&31] = (setTo)) ? 1 : 0;
}[/source] [size=1](no comments on the switching from booleans to int8 values, please, it's for unrelated reasons)[/size]
I register the get function as follows:
[source lang="cpp"]ASengine->RegisterGlobalFunction("bool get_triggers(uint8)", asFUNCTION(getTrigger), asCALL_CDECL);[/source]
Trying to access it through Angelscript, I get this paradigm:
[code]triggers[0] //this works fine, thankfully
foo::triggers[0] //this also works fine, but shouldn't[/code]
On the other hand, if I register the get function [i]in [/i]a namespace
[source lang="cpp"]ASengine->SetDefaultNamespace("Game");
ASengine->RegisterGlobalFunction("bool get_triggers(uint8)", asFUNCTION(getTrigger), asCALL_CDECL);[/source]
I get this:
[code]triggers[0] //ERR : 'triggers' is not declared
Game::triggers[0] //ERR : 'Game::triggers' is not declared
foo::triggers[0] //ERR : 'foo::triggers' is not declared
Game::get_triggers(0) //works
get_triggers(0) //doesn't work
foo::get_triggers(0) //doesn't work[/code]
I can also register it any of the following ways:
[source lang="cpp"]ASengine->RegisterGlobalFunction("bool Game::get_triggers(uint8)", asFUNCTION(getTrigger), asCALL_CDECL);
ASengine->RegisterGlobalFunction("Game::bool get_triggers(uint8)", asFUNCTION(getTrigger), asCALL_CDECL);
ASengine->RegisterGlobalFunction("Game::bool Game::get_triggers(uint8)", asFUNCTION(getTrigger), asCALL_CDECL);[/source]
the latter two of which probably shouldn't even compile, and still get the same results.

(Everything I mention applies to the set function too, so I left it out for the sake of brevity.) As I understand it, proper behavior would be for get_triggers registered outside of any namespaces to be accessible only as "triggers", never as "foo::triggers", and get_triggers registered inside a namespace to be accessible only as "foo::triggers" instead of, well, never. Is this the right intended behavior? It's not what I'm getting. Edited by Andreas Jonsson

You seem to have discovered a bug related to namespaces and virtual property accessors in AngelScript.

I'll have a look at this.
