Requirements Specification. An MMORPG Game Using Oculus Rift

Transcription

1 1 System Description CN1 An MMORPG Game Using Oculus Rift The project Game using Oculus Rift is the game application based on Microsoft Windows that allows user to play the game with the virtual reality technology (for our program, we tested and implemented with Oculus Rift) Rather than a LED or LCD monitor (But in case of user have none of a virtual reality technology a monitor is supported), user will have to setup their computer for supporting a Oculus Rift then launch our program to play the game. Our game does not only provide a virtual reality technology support but it also allows user to act or communicate the game system with their voice for some part of the game (Not a mandatory user have the right to using it or not). Our game is an MMORPG base (Massive multiplayer online role playing game) and not only supports multiplayer but single player is also a choice (character progress for multiplayer and single player is separate from each other, an internet is required in multiplayer). The game controller can be both gamepad or keyboard and mouse. 1.1 Perspective The relationship between our game using oculus rift and other systems, game engines and users is shown in Figure 1. Game using oculus rift project is the output of all component that been implemented and combined within Unity (Game Engine) for most of the project excluding authentication part (registered, login and user information management). Authentication will be provided outside the application product but it is created by our team. Data base will be separate in to two place depend on type of using. For the single player data based that keep the game information and An MMORPG Game using Oculus Rift 1

2 character progress will be saved in application database (local computer) but for the multiplayer data based will provide and keep the data within game server. Users can be anyone. 1.2 Functions The functions of Game Using Oculus Rift are shown in Figure 2. The functions are summarised as: Authentication: Connects between application and game server together provide with registration system and login system, keep user information within their data based. Unity: Unity game engine will provide all component for the game play including game world generating, controller, Screen display, Voice recognition, AI, Map, NPC, Item, Characters,, and In game objects all of these component or function will have a data base for keep their information with in Unity. Database: Database will get or store the users information authentication and then send back data to user application for playing. Database will also store the in game objects information. Voice Command: Allow users to speak to the microphone and recognize some specific words, then do the in game actions according to the voice. Oculus SDK: Generates the 360 degrees images and send it to Oculus Rift. Game World: Generates world map and that contains in game objects in there. In Game Objects: Provide all components for game playing which includes game environment, characters, monsters, items, and etc. An MMORPG Game using Oculus Rift 2
