Programming and Technology/Game Programming Patterns for Beginners

International Game Developers Association

This guide is intended for novice programmers who have a working understanding of C++ but have little experience programming games. It is a collection of programming patterns that will focus entirely on the structure of game programming, rather than any specific API like DirectX or OpenGL.

As game programming is truly a symposium of other areas of programming, you'll find that most of these patterns are used quite often outside of the game industry. This is just a selection of patterns which solves many of the challenges of game programming.

Overriding Concept

This should be filled with a description about Coupling, Stability, and Orthogonality. Why engineering is important, and what patterns hope to accomplish.

Traditional Patterns

Creational Patterns

The Singleton Pattern - A structure for a unique object or sub-system in the game.

The Factory Pattern

Behavioral Patterns

The Command Pattern

The Model View Controller Pattern

Game Specific

Engine

Sub-Systems - A logical way to separate different systems in a game engine

Dealing With Heterogeneous Data Types

The Resource Manager

The Game Loop - The core of all games.

Frame Rate Independence - How to make sure your game always moves at the same speed.

Physics

AI

The Strategy Pattern
