      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.

AngelScript 2.24.1 is released

9 posts in this topic

Awesome!

Mixins will be a great addition. i use lots of inheritance in my game.
interfaces do not cut it.

Do you have any plans for partial module compilation?
like module->RemoveScriptSection(...)
or adding one modules byte code to another module.
asIScriptModule::AddByteCode(asIBinaryStream *)

probably there are infinite ideas.. Edited by saejox

I haven't given partial module compilation much thought, though it is not the first time people ask for it.

It's already possible to dynamically add and remove global [url="http://www.angelcode.com/angelscript/sdk/docs/manual/classas_i_script_module.html#a1258d7cfeed965f36ba312beeb49e81c"]functions [/url]and global [url="http://www.angelcode.com/angelscript/sdk/docs/manual/classas_i_script_module.html#a34850e152dcdcb58c53a2b6929cebf77"]variables[/url], but it will probably not be that easy to expand this to types (classes, interfaces, etc).

Markus mentioned that in his patch he has implemented something like AddByteCode(), I might be able to incorporate that in the library too, but I've yet to dig into the details of what that implies.

Andreas, do the changes introduced in this release (actually, back in 2.24.0) break compatibility with the JIT? I noticed some members in asCContext had their names changed, but today I compiled my project (which worked fine with the JIT using Angelscript 2.23) and if I use the JIT my app just hangs.

The JIT was broken (mostly by the new nested context feature, the member name change was very minor). I fixed it a day ago, but forgot to commit the changes. If you update, you'll be compatible with 2.24.1.

Just a few hours after the release I receive a bug report with 3 more problems related to namespaces. :(

Anyway, this has now been fixed in revision 1388. So for those who plan on using it probably want to pick up those changes too.

Regards,
Andreas

Andreas, I´ve noticed a decrease in performance with this version compared to 2.23.1.

For the exact same code executing the exact same script for both versions 2.23.1 and 2.24.1 (with their corresponding JITs), I´m getting this readings:

2.23.1
Task #1 : CPU 0%
Task #2 : CPU 3 - 4%

2.24.1
Task #1 : CPU 0 - 6%
Task #2 : CPU 4 - 6%

While this are readings taken by the Task Manager (in Windows) and not by a proper profiler, they still show that there has been a significant loss of performance with the new version. Have there been any significant changes in the execution path that might be introducing this? Maybe some allocations and / or if/then checks?

Anything change can affect the performance. While I always try to maintain a good performance, my main priority is correctness, and sometimes performance suffers a bit for that.

I really can't say if there is anything specific that would have affected the performance that you see. It depends a lot on how exactly you're using the script library. If you can do some profiling on the code and let me know the bottlenecks the profiler identifies I'd gladly take a look at improving those for a future release. Edited by Andreas Jonsson
