A Space Game
By
William Sistar
The Problem
What is provided: Most network games are single player Some do allow team work but not in a common
environment What we want:
A networked game designed around team play Team members work together to manage what they
cannot on their own Team members play the roles they either like to or that
they do best
A Solution
A Space Game A team based, networked, multi-player
game Designed to be played with at least 4
players Players would be in teams of at least 2 Theme: Spaceship fighters Roles:
Pilot – Controls spaceship maneuvers Gunner – Manage weapon systems
The Requirements
Functional Common
Communication protocol Message handling Data structures for managing player information
The Requirements
Server Capable of authentication Ability to create and delete games Handle multiple games at once Modular for future requirements
The Requirements
Functional Game
Player should be able to remain logged in to server Allow for player selection of team and position Allow for at least 2 players and 2 teams
For demo purposes 1 player on each team At least one ship with at least one weapon Collision detection (for weapon fire) Provide smooth display of enemy ships when in view Support joystick and keyboard for control Have a scoring system to determine a winner Provide basic sound effects
The Design
Spiral design process Prototyping used for research and proof of
concept Client – Server model Design with cross-platform in mind Modular for future expansion

The Challenges
Object synchronization Collision detection Graphical Display Client – Server communication Development and Testing Time constraint Requirement creep Interest balanced with other commitments
Conclusion
I have developed a networked game designed around team play
Completed a project involving many facets of Computer Science
Learned many lessons about game design and project management
