Abstract

In the market of First Person Shooter (FPS) games, Massively Multi-player Online FPS games (MMOFPS) like 'PlanetSide 2' have been popular recently. Dead reckoning has been widely used in order to mitigate the network traffic overload for the game server with hundreds or thousands of people. This paper proposes the efficient analytical method to calculate the tolerable threshold angle of moving direction, which is one of the most important factors for character status updating when dead reckoning is used in MMOFPS games. The experimental results with game testers shows that the proposed method minimizes the position error for character moving and provides natural direction updates of characters.

최근 First Person Shooter (FPS) 게임 시장에서 '플래닛 사이드 2'를 비롯한 대규모 온라인 FPS (MMOFPS: Massively Multi-player Online FPS) 장르가 주목받고 있다. 수백 또는 수천명이 접속하는 게임 서버에서 네트워크 부하를 경감시키기 위해서 널리 사용되는 방법 중 하나는 데드레커닝이다. 본 논문에서는 MMOFPS 게임을 위한 데드레커닝 구현 시 주요 캐릭터 상태 갱신 변수 중 하나인 방향에 대하여 효율적으로 허용 임계각을 계산하는 수학적 방법을 제안한다. 제안하는 방법은 게임사용자들을 대상으로 하는 수행 실험을 통해 움직임 오차를 최소화하며 자유스러운 방향 갱신에 대한 효율성을 검증 하였다.
