This document discusses the components and elements of computer games. It outlines key game components such as objectives, gameplay theme, player characters, non-player characters, sound, feedback, rewards, physics, and visuals. It then discusses the components of a simple game including players, play area, scoring, controls, and non-player characters. An example of the simple game Bejeweled is provided. Finally, it outlines the components of a complex game and discusses game rules, consistency, and how a game engine coordinates the various game components.

– Players move the controller up/down/left/right and press a button
to position jewels
– Determine how you score points e.g. line up jewels in groups of

– Rules apply to all players
– Must be made clear and understandable for all players
– Rules are set and remain constant throughout the game
5. Components of a complex game
• A more complex game consists of:
– Objectives
– Story
– Sounds
– Feedback
– Rewards/achievements
– Game play theme
• Kameo
6. Game Rules
• The game is governed by sets of rules
– Player rules
• What your character can do
– Non player rules (AI)
• How non player characters react to you and their
environment
– Design rules (weather, environment, objects)
• How do the objects react within the environment
– Consistency
• Rules will be consistent throughout game play
7. Game Engine
• How are game components created and
coordinated in games
– Through the use of a game engine which usually
consists of:
•
•
•
•
•
AI Engine
Physics Engine
Graphics Engine
Control
Networking Tools
– Game engines can be 2D, 3D or genre specific
– A game or game engine can be coded from scratch
