Description

<p>This study is a proposal about the design patterns of character AI in 3D action games. Currently, there is no fixed method for the development of character AI in digital games. Therefore, this study proposes a method using pattern language as a development method for character AI. This method consists of four processes: “sampling character behavior from games “, “creating pattern language”, and “implementing pattern language”, “verifying pattern language”. A list of character AI design patterns that character AI should follow was created based on character behaviors that users felt unnatural. Next, the behavioral patterns of compliance and non-compliance with each norm of the list were implemented on a game engine (Unreal Engine 5) and compared each other. The implementation of four design patterns in the list was explained and their effectiveness showed in this article.</p>
