      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.

  1. LifeAI is an open source C++ library for Artificial Intelligence decision-making. It can be integrated in video games, robotics, or anything that requires simulated intelligence. Entities and actions are created in C++ and text files with LifeAI's syntax.  Entities have characteristics that describe them called "stats".  They consider their value of the stats and how much they are modified to assess the "pros" and "cons" of an action.  They also consider their value of other entities involved in the action and how it affects them.  They can then determine an overall value for performing the action.  As stats in the simulation change, LifeAI updates the best action options for the entities. The actions can then be implemented as needed in a simulation.  LifeAI is licensed under the MIT (X11) license.   As IADaveMark pointed out in my original LifeAI thread, LifeAI best fits in the "Utility Theory" model for AI. Per his explanation, "Utility can represent anything that can be put on a continuum. Whether it be bullets in your gun, hunger, or a level of happiness, anger, etc. It's all numbers."  It does not provide all of these numbers, values, and weights for you.  But it does provide a thoughtfully crafted utility-based decision architecture.   Highlights of Version 1.1 include: - Actions with negative values can now be selected as the "best action". Enables entities to choose the "lesser of two evils," if an action with a positive value is not an option. - Added support for new "string" type. Convenient for storing words or phrases in LifeAI files. - Added feature for creating multiple instances of variables, stats, strings, entities, and actions in LifeAI files at the time of their creation. - Added laiSetLink() and laiSync() functions as an alternative way to sync data to and from LifeAI. Allows linking the memory address of a data type such as a floating point number to a variable, stat, or string in LifeAI. When laiSync() is called, syncs changes in the data to LifeAI.   Download LifeAI Video of LifeAI Demo App Video of LifeAI applied to a robot  
  2. @ IADaveMark - Wow, there appear to be many similarities in our approaches to AI. I can see some of the challenges I've encountered discussed in your work too. I would love to get your feedback on LifeAI sometime
  3. @IADaveMark - Ah, okay. So there IS an established term for this approach, "Utility". I appreciate the info.
  4. Thanks for the responses. @ VJo1 - LifeAI can already simulate emotions to some extent. You can make stats that represent emotions such as "happy, sad, fear, anger", ect... You can then design actions that involve or modify their emotion levels. LifeAI also contains a function laiGetSat() that attempts to retreive an overall satisfaction level of an entity based on their stat levels and values of those stats. @ _orm_ - LifeAI is not based on a common approach to AI, but it probably has similarities. A basic description is provided in the original post, but a more detailed description can be obtained here: [url="http://www.lifeai.com/guide_files/general.html"]http://www.lifeai.co...es/general.html[/url] I recommend viewing the video of the demonstration application here: [url="http://vimeo.com/28839032"]http://vimeo.com/28839032[/url] You can also download it [url="http://www.lifeai.com/download.html"]http://www.lifeai.com/download.html[/url] if you'd like to try it. It includes a text file that demonstrates how entities, stats, values, and actions all contribute to the logic of the system.
