  • 본 논문에서는 실감형 Networked Virtual Environment (NVE)의 사실성 증진을 위한 Non Player Character (NPC)의 지능적 제어 프레임워크를 제안한다. 이 프레임워크는 반응의 다양성, 실시간성 그리고 NPC의 능동성면에서 기존 게임에서 사용되는 NPC 구현 기법과 차이가 있다. 기존 NPC 제어구조의 경우, 휴먼 사용자의 행동에 따른 NPC의 반응이 일정 스크립트나 규칙에 따르기 때문에 정형적이며, 또한 NPC의 반응시간에 대한 실시간성을 고려하지 않고 있다. 또한 NPC는 휴먼 사용자의 액션에 반응하는 종속적이고 수동적인 역할만을 담당한다. 제안하는 프레임워크에서는 NPC는 각자의 취향을 가지고 있어 다양한 반응과 행동양식을 보일 수 있으며, NPC의 행동 결정 시간에 어느 정도 실시간성을 부여할 수 있으며, 또한 NPC의 역할이 수동적 형태에서 벗어나 능동적으로 계획하여 행동을 실행할 수 있다. 프레임워크의 구현을 위해 SWI-Prolog의 Rule based 추론엔진과 유전자 알고리즘을 사용하였다.

  • The non-player character(NPC) either cooperates with the player character to proceed the game or fight against the game player. This paper proposes the context awareness method for the natural action control of the same NPC. The context awareness method analyzes the context information of the NPC that can be utilized in the current status and creates the actions which suit the current context automatically. The context awareness method analyzes the information value of the context elements of the NPC which occur in the current context and creates natural actions of the character by utilizing the analyzed context element information. In this experiment, average performance improved by 39% and by 8% in the context awareness method as compared to the rule-based method and information gain method, respectively.

  • The purpose of this study is to show typology of Non Player Character(NPCs) and to look out what narrative functions of NPCs are served in Massively Multi-player Online Role-Playing Game(MMORPG). As the relationship with player characters and the propensity of actions, NPCs are classified 4types; passive helper, active helper, passive antagonist, active antagonist. Each type performs different functions of game narrative. Especially passive helper functions as a essential glue of movement in game world and makes the chain of quest narratives. Active antagonist functions as the cause of space perspective and creates dramatic effect of game narrative. Those functions make spacial, dimensional and extensible game narrative.

  • Recently AI(Artificial Intelligence) is one of the issues in the on-line game, a research that a game character seems to be realistic and is progressing using AI technique. Especially NPC is an important part of the AI researches of on-line game, and it is concerned by a game player and an architect. We proposed an intelligent agent framework to implement the NPC technique after studying the NPC technique using context awareness that reacts to the PC(Player Character) actively. Also, it can be developed gradually, and apply to various application because it has the capability to of adding an agent or deleting an agent easily.

  • Users connect to game server for considerably many hours and perform their roles in MMORPG(Massively Multiplayer Online Role Playing Game), users' immersion degree is very higher than other games, have known affluent contents make users play various roles in game world. However, although contents of games are improved quite much, MMORPG remains still boring game. It is because that the NPC (Non Player Character)' behavior patterns that are the most important elements to make games fun are so simple.

  • 포괄적인 개념에서, 게임에서 인공지능이란 PC(Player Character, 사용자에 의해서 조정되는 게임 오브젝트)를 제외한 모든 것들을 제어하기 위해 사용되는 일련의 기술이라고 정의할 수 있다. 예를 들면, PC를 둘러싸고 있는 환경, PC를 대적하거나 경쟁관계에 있는 NPC(Non-Player Character), PC에 조언을 해주는 조언자 NPC 등을 제어하고 사용자가 느끼기에 지능적이면서 실제적인 것으로 보이도록 하여 게임의 흥미를 더하기 위한 기술들이다. (중략)

  • 게임이나 가상환경에서 오락성과 실감성을 증진시키는 여러 가지 방법들 가운데 지능적인 Non-Player Character (NPC)들의 존재는 중요하다. 컴퓨터 그래픽과 관련 하드웨어 플랫폼 기술의 발전으로 인해 사용자들은 이제 시각적인 만족을 넘어서서, NPC들이 보다 지능적으로 행동하면서 오락적인 만족감과 동시에 보다 향상된 실감성을 제공하기를 원한다. 하지만, 유한상태기계 (Finite State Machine, FSM)를 기반으로 하는 NPC 구현의 한계와 어려움으로 인해 이러한 사용자들의 요구사항을 만족시키는 것은 어렵다. 본 논문에서는 FSM과 추론 엔진(Inference Engine)을 결합한 새로운 NPC 행동제어 구조를 제안한다. 또한 제안된 구조의 가능성을 시연하기 위해 실제로 동작하는 데모를 소개한다. 이러한 FSM과 추론 엔진의 하이브리드 구조는 FSM이 제공하는 NPC 반응의 실시간성을 보장하는 동시에 추론 엔진이 제공할 수 있는 보다 지능적이고 계획적인 NPC들의 행동을 만들어 낼 수 있다는 장점이 있다.
