Decision model of NPC based on the definition of morality

Abstract

Controlling a behavior of Non-Player-Character (NPC) which appears in digital game has several tasks. In this research, by focus on ``communication" ``emotion" and ``mechanism of cooperation", we constructed ``NPC's decision-making model" which decides behavior based on the character assumed by the game designer. We constructed the model inspired by Hume's moral sentiment. We created a test case to confirm behavior, for 3D battle game, and confirmed the result. As a result, NPC's decision was made normally and no deadlock was confirmed. As future tasks, it needs to add test cases and add intuitively operable interfaces for game designers.
