Deriving Quests from Open World Mechanics

Open world games present players with more freedom than games with linear progression structures. However, without clearly-defined objectives, they often leave players without a sense of purpose. Most of the time, quests and objectives are hand-authored and overlaid atop an open world's mechanics. But what if they could be generated organically from the gameplay itself? The goal of our project was to develop a model of the mechanics in Minecraft that could be used to determine the ideal placement of objectives in an open world setting. We formalized the game logic of Minecraft in terms of logical rules that can be manipulated in two ways: they may be executed to generate graphs representative of the player experience when playing an open world game with little developer direction; and they may be statically analyzed to determine dependency orderings, feedback loops, and bottlenecks. These analyses may then be used to place achievements on gameplay actions algorithmically.Comment: To appear at Foundations of Digital Games (FDG) 201

Generative Design in Minecraft (GDMC), Settlement Generation Competition

This paper introduces the settlement generation competition for Minecraft, the first part of the Generative Design in Minecraft challenge. The settlement generation competition is about creating Artificial Intelligence (AI) agents that can produce functional, aesthetically appealing and believable settlements adapted to a given Minecraft map - ideally at a level that can compete with human created designs. The aim of the competition is to advance procedural content generation for games, especially in overcoming the challenges of adaptive and holistic PCG. The paper introduces the technical details of the challenge, but mostly focuses on what challenges this competition provides and why they are scientifically relevant.Comment: 10 pages, 5 figures, Part of the Foundations of Digital Games 2018 proceedings, as part of the workshop on Procedural Content Generatio

Sonancia : sonification of procedurally generated game levels

How can creative elements brought from level design effectively be coupled with audio in order to create tense and engaging player experiences? In this paper the above question is posed through the sonification of procedurally generated digital game levels. The paper details some initial approaches and methodologies for achieving this core aim.The research is supported, in part, by the FP7 ICT project C2Learn (project no: 318480) and the FP7 Marie Curie CIG project AutoGameDesign (project no: 630665).peer-reviewe

Node-Based Native Solution to Procedural Game Level Generation

A Geração Procedural de Conteúdo (PCG) aplicada ao domínio do desenvolvimento de jogos tem se tornado um tópico proeminente, com um número crescente de implementações e aplicações. Soluções de PCG standalone e plugin, regidas por interfaces baseadas em nós e outros modelos de alto nível, enfrentam limitações em termos de integração, interatividade e responsividade quando inseridas no processo de desenvolvimento de jogos. Essas limitações afetam a experiência do utilizador e inibem o verdadeiro potencial que estes sistemas podem oferecer. Adotando uma metodologia de Action-Research, realizou-se um estudo preliminar com entrevistas a especialistas da área. A avaliação da pertinência desta metodologia nativa e da abordagem visual mais adequada para a sua interface foi efetuada através de uma série de protótipos. Posteriormente, foi implementado um protótipo funcional e conduzido um estudo de caso com uma amostra constituída por um grupo de especialistas em PCG e de desenvolvedores de jogos. Os participantes realizaram uma série de exercícios que estavam documentados com os respetivos tutoriais. Após a conclusão dos exercícios propostos, os participantes avaliaram a relevância da solução e da experiência do utilizador através de um questionário. No desenvolvimento de uma metodologia nativa de PCG baseado em nós, integrado no motor de jogo, identificamos limitações e concluímos que existem diversos desafios ainda por superar no que diz respeito a uma implementação completa de um sistema complexo e amplo.Procedural Content Generation (PCG) applied to game development has become a prominent topic with increasing implementations and use cases. However, existing standalone and plugin PCG solutions, which use Node-based interfaces and other high-level approaches, face limitations in integration, interactivity, and responsiveness within the game development pipeline. These limitations hinder the overall user experience and restrain the true potential of PCG systems. Adopting an Action-Research methodology, a preliminary interview was conducted with experts in the field. The relevance assessment of this native methodology and the most suitable visual approach for its interface was carried out through a series of prototypes. Subsequently, a functional prototype was implemented, and a case study was conducted using a sample consisting of a group of PCG experts and game developers. The participants performed a series of exercises documented with the respective tutorials. After completing the exercises, the solution's relevancy and user experience were evaluated through a questionnaire. In developing a native node-based PCG methodology integrated into the game engine, we identified limitations. We concluded that several challenges are yet to be overcome regarding fully implementing a complex and extensive system

Designer modeling for personalized game content creation tools

With the growing use of automated content creation and computer-aided design tools in game development, there is potential for enhancing the design process through personalized interactions between the software and the game developer. This paper proposes designer modeling for capturing the designer’s preferences, goals and processes from their interaction with a computer- aided design tool, and suggests methods and domains within game development where such a model can be applied. We describe how designer modeling could be integrated with current work on automated and mixed- initiative content creation, and envision future directions which focus on personalizing the processes to a designer’s particular wishes.peer-reviewe

Enhancing performance proficiency at the expert level: Considering the role of 'somaesthetic awareness'

© 2014 Elsevier Ltd. Objectives: Traditional theories of motor learning (e.g., Fitts & Posner, 1967), along with certain contemporary psychological perspectives (e.g., Weiss & Reber, 2012; Wulf, 2013), postulate that expert performers must relinquish paying conscious attention to, and/or attempting to exert control over, their bodily movements in order to achieve optimal performance. Challenging such largely unquestioned conceptual approaches, however, is an emerging body of evidence (e.g., see Montero, 2010; Shusterman, 2011) which indicates that 'somatic reflection' (i.e., a conscious focus on bodily movement) is an important mediator of continuous improvement (i.e., the fact that certain performers continue to improve their skills even after becoming experts) at the elite level of sport. The present position paper seeks to elucidate and resolve this apparent paradox concerning the role of bodily awareness in expertise. Design: Literature review and position statement. Method: To achieve this latter aim, we draw on empirical evidence (e.g., from research on somatic attention) and theory (e.g., Shusterman's, 2008, theory of body consciousness) to elucidate the role of bodily awareness in facilitating continuous improvement at the elite level of sport. Results and conclusion: In doing so, we sketch some theoretical and practical implications of Shusterman's (2008, 2011, 2012) theory of 'somaesthetics' for contemporary research on expertise in sport

Customizing Experiences for Mobile Virtual Reality

A criação manual de conteúdo para um jogo é um processo demorado e trabalhoso que requer um conjunto de habilidades diversi cado (normalmente designers, artistas e programadores) e a gestão de diferentes recursos (hardware e software especializados). Dado que o orçamento, tempo e recursos são frequentemente muito limitados, os projetos poderiam bene ciar de uma solução que permitisse poupar e investir noutros aspectos do desenvolvimento. No contexto desta tese, abordamos este desa o sugerindo a criação de pacotes especí cos para a geração de conteúdo per sonalizável, focados em aplicações de Realidade Virtual (RV) móveis. Esta abordagem divide o problema numa solução com duas facetas: em primeiro lugar, a Geração Procedural de Conteúdo, alcançada através de métodos convencionais e pela utilização inovadora de Grandes Modelos de Lin guagem (normalmente conhecidos por Large Language Models). Em segundo lugar, a Co-Criação de Conteúdo, que enfatiza o desenvolvimento colaborativo de conteúdo. Adicionalmente, dado que este trabalho se foca na compatibilidade com RV móvel, as limitações de hardware associadas a capacetes de RV autónomos (standalone VR Headsets) e formas de as ultrapassar são também abordadas. O conteúdo será gerado utilizando métodos actuais em geração procedural e facilitando a co-criação de conteúdo pelo utilizador. A utilização de ambas estas abordagens resulta em ambi entes, objectivos e conteúdo geral mais re-jogáveis com muito menos desenho. Esta abordagem está actualmente a ser aplicada no desenvolvimento de duas aplicações de RV distintas. A primeira, AViR, destina-se a oferecer apoio psicológico a indivíduos após a perda de uma gravidez. A se gunda, EmotionalVRSystem, visa medir as variações nas respostas emocionais dos participantes induzidas por alterações no ambiente, utilizando tecnologia EEG para leituras precisas
