Abstract :
Storytelling is an important feature in games and also other types of (semi) automated entertainment systems such as machinima and digital-TV. The majority of the current research in storytelling use precedence-based directed acyclic graphs, or even linear sequences, to model the ordering of events in a story. This approach makes it easier to plan, recognize and perform these events in real-time, but it is also too simple to represent complex human actions, which form the basis of the most interesting stories in this niche. PNF-Networks and Interval Scripting are frameworks to represent, recognize and perform human action that was proposed in the context of computer-aided theatre. In this paper we describe two extensions to this framework that were designed and developed to enable its use in larger scale storytelling systems: Hierarchical PNF-Networks and a template-based definition. Hierarchical PNF-Networks present lower complexity propagation heuristic while the definition language enables high-level and abstract description of the temporal structure of the actions and events that compose an interactive story or game.
