본 논문에서는 대표적인 3차원 일인칭 액션 게임(first-person action game)인 Unreal Tournament 게임과 이것에 기초한 Gamebots시스템을 소개하고, 이러한 환경에서 효과적으로 동작하는 지능형 NPC인 KGBot의 설계와 구현에 대해 설명한다. KGBot는 Gamebots시스템에서 하나의 보트 클라이언트(bot client)로 동작하면서 지형이 복잡한 3차원 가상환경 안에서 적들에 대항해 아군과 연합하여 특정 목표 지점(domination point)들을 찾아 점령하는 자율 NPC이다. KGBot는 BDI기반의 범용 에이전트 구조인 UM-PRS를 제어엔진으로 채용하고 있으며, 복잡한 행위들을 효과적으로 구현하기 위해 계충화된 지식베이스를 가지고 있다. 본 논문에서는 특히 제한적인 센서정보와 이동점(waypoint)에 기초하여 자신이 놓여진 월드의 전체지도를 작성하고 임의의 목적지까지 효율적인 이동경로를 계획할 수 있는 KGBot의 행위의 구현과 실험에 대해 설명한다.

In aspect of HCI(Human Computer Interaction) gameplay is the procedure to solve the problem that gamers encounter in order to generate or discover a new rule to achieve gamers' goal. The goal of this research is to investigate the structure and understand the gameplay in aspect of affordance from ecological psychology rather than the traditional problem solving theory. This research selects 'World of Warcraft' as MMORPG(Massively Multiplayer Online Role Playing Game). Five expert gamers participated in this experiment. We record all gameplay using audio and video device. We conducted protocol analysis as qualitative method based on the verbal report and action protocol during game playing. As result, gameplay based on affordance includes selection and relation. We found that subjects selected one thing at once with attention. Moreover, we found that there were two behaviors : exploratory action and performatory action. We believe that learning, utilization, and transformation for affordance appear. The result of this research imply to suggest design guideline for game design methodology when designers develop game.

In this paper we suggested a map management method for on line RPG supporting full 3D. In general, it is possible to support full 3D with client engine. Rut the online game server cannot show the expected performance under normal price constrains with current hardware technology, since the amount of data for management of 3D on-line game server increase exponentially with respect to the size of game world. To solve this problem. we introduced the "special object" which makes it possible for on-line game server with low performance hardware. This suggested method gave concrete from to manage full 3D for server as well as clients.s clients.

In MMORPGs(Massively Multi-player Online Role-Playing Games) a large number of players actively interact with one another in a virtual world. Therefore MMORGs must be able to quickly process real-time access requests and process requests from numerous gaming users. A key challenge is that the workload of the game server increases as the number of gaming users increases. To address this workload problem, many developers apply with distributed server architectures which use dynamic map partitioning and load balancing according to the server function. Therefore most MMORPG servers partition a virtual world into zones and each zone runs on multiple game servers. These methods cause of players frequently move between game servers, which imposes high overhead for data updates. In this paper, we propose a new architecture that apply with an arithmetic server dedicated to data operation. This architecture enables the existing game servers to process more access and job requests by reducing the load. Through mathematical modeling and experimental results, we show that our scheme yields higher efficiency than the existing ones.

Game graphics provide players with a sense of immersion, leading to active participation. This paper aims to analyze the mythological meaning for symbolic design of game skill visual effects that reproduce the narrative and the worldview of games borrowing myths. The research method classified the visual effect image into a symbol of the form of a universal archetype representation and a symbol of color expressing the narrative in the game, and analyzed it by applying Roland Barthes' semiological scheme. Through this study, it was possible to analyze the meaning of visual effects as a mythical meaning that can be universally sympathized and an implicit meaning that symbolizes the narrative of the game. The symbolic expression of the visual effect, which reproduces the narrative of the game reflecting the myth, can induce players to engage and participate, and the design direction was intended to provide the visual effect to have a unique symbolism that reflects the game's mythical worldview of the game.

최근에 축구 경기에 대한 많은 관심이 모아지고 있으며 축구 경기를 분석하는 시스템들도 다양하게 개발되고 있다. 본 논문에서는 축구 경기의 중요 장면을 3 차원 그래픽으로 재연하여 다각도의 영상정보를 제공하는 축구경기 3 차원 재연 시스템에 대해 소개한다. KBS 기술연구소에서는 2002년 한일 월드컵 축구대회 기간 중 시청자에게 새로운 영상을 제공하기 위해 'VPlay'라는 이름의 축구경기 3차원 재연 시스템을 개발하였다. VPtay 는 영상 처리 기술과 컴퓨터 그래픽 기술이 함께 사용되었다. 영상 처리 기술에는 선수 추출 및 추적, 그리고 카메라 이동 모델 및 추적 점에 대한 운동장으로의 좌표변환 모델 제작 방법이 사용되었다. 컴퓨터 그래픽 기술에서는 추적결과 데이터로부터 캐릭터의 기본적인 동작을 생성할 수 있는 이동동작 생성 기술을 적용하였고 가상 카메라의 효과적인 제어를 위해서 조이스틱을 이용한 가상 카메라제어 프로그램을 개발하였다. VPlay 는 빠른 제작시간을 요구하는 축구중계 생방송용으로 개발되었으며 지난 월드컵 경기와 아시안 게임에 효과적으로 활용하였다

The interaction property of digital media have changed traditional storytelling into a new concept, digital-storytelling, which has been widely accepted. Nowadays open-ended game storytelling, which different from story design of movie or animation, is chosen for the development of RPG. It can make infinite stories according to player character's decision. In this paper, we propose a game storytelling structure focused on the characters for RPG, and analyze how characters designed with various story-values interact with background stories and events in the cyber game world through case studies. This research is necessary to design predictable game mechanics and provide methods to control game play in case of special-purpose game.

As digital technology evolved, digital paradigm emerged and storytelling began to evolve. Especially, since digital storytelling is the core of the digital game, it is a tendency to develop content in consideration of the strategy of transmedia storytelling at the planning stage even for IP expansion. By fusing media in a variety of ways and expanding the story, players can experience meaningful storytelling in a new media environment and game loyalty allows game developers to expand and innovate their businesses. In this study, we analyzed the case of , a proven powerful IP that has been expanding its story to various media for more than 20 years in order to investigate the transmedia storytelling strategy based on game media. I would like to take a look at the strategy of using the transmedia storytelling.

A stable game managing system is absolutely needed to accept simultaneous interlacing of many users for on- line game system. The proposed P2P on-line game system in this paper is able to get stable and real-time game managing within limited time stamp utilizing through reorganizing peers according to synchronous time which can be avoid congestion on one region, it is possible to synchronize for game nodes within limited time stamp utilizing. Reorganizing M-tree which leads 10 distribute loads. The system manages each region unit, and it is execute no matter how big game sizes are. Thus to ensure such as the problems of expand server and stabilization or message transmission. Also, prove efficiency of the suggested system through the simulation.
