A character AI is a system that makes decisions for what a character will do. Here, a decision means a strategy, tactics, or a certain behavior. Character AI does not only refer to the decision-making process, but also to the whole system used for dynamically connecting the character’s AI and the game world. Such systems implement what is called as an “agent architecture” (Russell and Norvig 2016a). An agent architecture of character AI has three modules: perception, decision-making, and memory modules.
Introduction
In this entry, an overview on the history of the development of character AI is presented. Characters’ AI techniques differ depending on the scale of the game. For small-size games, “scripted AI” is the most used method for controlling a character, whereby a scripted AI system uses script languages to issue commands that directly determine characters behaviors. For middle-size games, decision-making...
