In many games sound also serves as an important game mechanism; in stealth games, for example, sounds triggered by player actions may attract enemy agents, and sounds created by enemy agents give useful information on where to target or avoid combat. Modelling sound, however, is computationally complex, and thus sound propagation is often restricted to highly localized contexts, or based on trivial propagation models such as a fixed radius that ignores the impact of obstacles. In this work, we describe an efficient approach to propagating sound in a real-time 2D game level. We use a heuristic ray-based approach, adapted to include diffraction, reflection, and transmission. Our design allows for dynamic geometries, avoids sound discontinuities, and can be tuned in various ways to trade-off accuracy for computation cost.","PeriodicalId":92576,"journal":{"name":"Proceedings.

The planner has an author goal it must achieve, but every action taken by an agent must make sense according to that agent's individual intentions and limited, possibly wrong beliefs. This paper describes the implementation of Sabre, which supports a rich action syntax and imposes no arbitrary limit on the depth of theory of mind. We present a search procedure for generating plans that achieve the author goals while ensuring all agent actions are explained, and we report the system's performance on several narrative planning benchmark problems.","PeriodicalId":92576,"journal":{"name":"Proceedings.

In creative spaces such as musical performance, they are able to exhibit creative autonomy through independent actions and decision-making. These systems, called co-creative systems, autonomously control some aspects of the creative process while a human musician manages others. When users perceive a co-creative system to be more autonomous, they may be willing to cede more creative control to it, leading to an experience that users may find more expressive and engaging.\u0000\u0000This paper describes the design and implementation of a co-creative musical system that captures gestural motion and uses that motion to filter pre-existing audio content. The system hosts two neural network architectures, enabling comparison of their use as a collaborative musical agent. This paper also presents a preliminary study in which subjects recorded short musical performances using this software while alternating between deep and shallow models. The analysis includes a comparison of users' perceptions of the two models' creative roles and the models' impact on the subjects' sense of self-expression.","PeriodicalId":92576,"journal":{"name":"Proceedings.

The industry perspective on this topic is also largely unknown. Thus, the purpose of this paper is to gain an understanding of the definition of a quest from industry professionals to better inform the academic community. We interviewed fifteen game developers with experience designing or implementing quests or narratives, and process the interviews using thematic analysis to identify trends. We identified a variety of personal developer definitions. However, we also discovered several themes that may inform future academic work. We introduce the definition-context-purpose paradigm as a synthesis of these trends: elements of a quest, purpose of a quest, and context of a quest. Finally, we discuss the developer’s reaction to a recently proposed quest definition as part of a push towards a general quest definition.","PeriodicalId":92576,"journal":{"name":"Proceedings.

Using a large study of chess games and applying the popular Word2Vec algorithm, we show that the resulting vector representation can reveal both common knowledge and subtle details about the game, including relative piece values and the natural spatial flow of chess play. Our results suggest that word embeddings are a cheap and simple technique that can provide a broad overview of a game’s dynamics, helping designers and critics form new hypotheses about a game’s design, structure and flow.","PeriodicalId":92576,"journal":{"name":"Proceedings.

Though sifting has successfully been used to enable novel computational narrative play experiences, its utility is limited by the fundamentally retrospective nature of existing sifters, which can only recognize storyful event sequences once they have fully played out. To address this limitation, we introduce Winnow: a domain-specific language for specifying story sifting patterns that can be executed incrementally to detect potentially storyful event sequences while they are still playing out. We evaluate Winnow by applying it to several specific use cases and show that it is well-suited to the implementation of prospective as well as retrospective narrative intelligence.","PeriodicalId":92576,"journal":{"name":"Proceedings.

In this project we integrate 'Squeezer', a tool for generating visual and audio effects (sometimes called 'juice') for games, with 'Puck', an automated game designer. The resulting hybrid system can design games and then generate appropriate sets of effects, making it the first automated game design system that directly engages with 'juiciness' in design. We support this work with a user study, measuring player responses to games with simple animations, effects automatically designed and arranged by Puck, and effects designed and arranged by an expert human designer. We then dissect the engineering challenges presented by integrating the two systems, and the new research questions raised by applying juice through automated game design systems.","PeriodicalId":92576,"journal":{"name":"Proceedings.
