In this paper we focus on proactive behavior for nonplayer characters
(NPCs) in the first-person shooter (FPS) genre of video games based on
goal-oriented planning. Some recent approaches for applying realtime
planning in commercial video games show that the existing hardware is
starting to follow up on the computing resources needed for such
techniques to work well. Nonetheless, it is not clear under which
conditions real-time efficiency can be guaranteed. In this paper we
give a precise specification of SimpleFPS, a STRIPS planning domain
expressed in PDDL that captures some basic planning tasks that may be
useful in a first-person shooter video game. This is intended to work
as a first step towards quantifying the performance of different
planning techniques that may be used in real-time to guide the
behavior of NPCs. We present a simple tool we developed for generating
random planning problem instances in PDDL with user defined
properties, and show some preliminary results based on SimpleFPS
instances that vary in the size of the domain and two wellknown
planners from the planning community.
Stavros Vassos received his B.Sc. degree from the Electrical and
Computer Engineering Department of the National Technical University
of Athens in Greece. In 2005 he received the M.Sc. degree and in 2009
the Ph.D.degree from the Computer Science Department of the University
of Toronto under the supervision of Professor Hector J. Levesque. He is
currently working as a research associate at the National and Kapodistrian
University of Athens in Greece. His research interests lie mainly in the
area of Artificial Intelligence, in particular logic-based approaches for
Knowledge Representation and Reasoning, Reasoning about Action and
Change, as well as Intelligent Agent Design. During his studies in the
University of Toronto he was an active developer of the high-level agent
programming language IndiGolog. In 2008 he recieved the AAAI
Outstanding Paper Honorable Mention Award for his joint paper with
Professor H. J. Levesque "On the Progression of Situation Calculus Basic
Action Theories: Resolving a 10-year-old Conjecture".
