    International audienceThis work presents a driving system designed for virtual racing situations. It is based on a complete modular architecture capable of automatically driving a car along a track with or without opponents. The architecture is composed of intuitive modules, with each one being responsible for a basic aspect of car driving. Moreover, this modularity of the architecture will allow us to replace or add modules in the future as a way to enhance particular features of particular situations. In the present work, some of the modules are implemented by means of hand-designed driving heuristics, whereas modules responsible for adapting the speed and direction of the vehicle to the track's shape, both critical aspects of driving a vehicle, are optimized by means of a genetic algorithm that evaluates the performance of the controller in four different tracks to obtain the best controller in a large number of situations; the algorithm also penalizes controllers that go out of the track, lose control, or get damaged. The evaluation of the performance is done in two ways. First, in runs with and without adversaries over several tracks. And second, the architecture was submitted as a participant to the 2010 Simulated Car Racing Competition, which in end won laurels

    Understanding computer game culture: the cultural shaping of a new medium

    In the past few decades, video games have developed from a marginal technological experiment into a mainstream medium. During this period they have gone through several transformations, from arcade machines offering a few minutes of solitary fun for a quarter to monthly subscription-based online MMOs in which thousands of players spend hundreds or even thousands of hours and lead a significant part of their social life as a fantasy character. But what is it that has driven video games? development? Is it technology? Indeed, with every new generation of hardware, game designers were given a broader set of tools for evoking exhilarating experiences. But is not culture at least as important? What would games look like if Tolkien never had written Lord of the Rings, or if Nintendo had not brought Japanese manga drawing styles to the new medium? This book looks at the theoretical challenges and foundations on which to base a cultural shaping approach towards the evolution of video games and proposes a set of concepts for analyzing and describing this process

    Advanced overtaking behaviors for blocking opponents in racing games using a fuzzy architecture

    No full text
    In car racing, blocking refers to maneuvers that can prevent, disturb or completely block an overtaking action by an incoming car. In this paper, we present an advanced overtaking behavior that is able to deal with opponents implementing blocking strategies of various difficulty level. The behavior we developed has been integrated in an existing fuzzy-based architecture for driving simulated cars and tested using The Open Car Racing Simulator (TORCS). We compared a driver implementing our overtaking strategy against four of the bots available in the TORCS distribution and Simplix, a state-of-the-art driver which won several competitions. The comparison was carried out against opponents implementing three blocking strategies of increasing difficulty and two different scenarios: (i) a basic scenario with one opponent on a straight stretch to overtake as quickly as possible; (ii) an advanced scenario involving a race on a non-trivial track against several opponents. The results from the basic scenario show that our strategy can always overtake the opponent car; in particular, our strategy is slightly more risky than the other ones and may result in a little damage, however, all the other controllers show a more careful and safe policy that often prevents them to complete an overtaking maneuver. When racing against several opponents on complex tracks, our strategy results in the best trade-off between the time spent being blocked by an opponent ahead and the number of overtaking maneuvers completed

    Rethinking gamification

    Gamification marks a major change to everyday life. It describes the permeation of economic, political, and social contexts by game-elements such as awards, rule structures, and interfaces that are inspired by video games. Sometimes the term is reduced to the implementation of points, badges, and leaderboards as incentives and motivations to be productive. Sometimes it is envisioned as a universal remedy to deeply transform society toward more humane and playful ends. Despite its use by corporations to manage brand communities and personnel, however, gamification is more than just a marketing buzzword. States are beginning to use it as a new tool for governing populations more effectively. It promises to fix what is wrong with reality by making every single one of us fitter, happier, and healthier. Indeed, it seems like all of society is up for being transformed into one massive game.The contributions in this book offer a candid assessment of the gamification hype. They trace back the historical roots of the phenomenon and explore novel design practices and methods. They critically discuss its social implications and even present artistic tactics for resistance. It is time to rethink gamification

    Red Perimeter Defeated: U.S. Naval Supremacy, Competitive Adaptation, and the Third Battle of the Atlantic, 1946-1981

    Get PDF
    This dissertation examines the long-term military competition between the U.S. and Soviet navies during 1946-81. It investigates the dynamics of naval posture change by integrating insights from military innovation theory with in-depth process tracing, thus providing a much-improved understanding of the Cold War at sea during the most decisive phases of the 'Third Battle of the Atlantic'
