A tool for programming the behaviour of intelligent virtual agents in Prolog

The definition of intelligent virtual agent behaviour is a key stage in the process of developing any intelligent virtual environment application. Ranging from simple scripting languages to full-featured, general-purpose programming languages, the means available to developers for defining agent behaviour are bound by the choice of development methodology and platform for the entire system. In this paper, we present a tool for programming the behaviour of intelligent virtual agents in intelligent virtual environment applications on an implementation-independent basis using the Prolog language. Our aim is to evaluate the potential of Prolog as a means for defining intelligent virtual agent behaviour as well as extend our previous work in the field.
