Overview

In working through the entire book, an aspiring game programmer will gain an in-depth understanding of a game engine. Such a programmer will not only know how a game engine is implemented, but also why it is implemented the way it is, understanding choices required to achieve general purpose functionality to support a variety of games. Moreover, an aspiring game programmer will understand game programming from the game programmer's point of view, being able to differentiate functionality in game code versus functionality provided by the game engine. This understanding will be reinforced by making a game, albeit a simple one, using a full-featured, fully functional game engine. Lastly, and for some perhaps most importantly, an aspiring game programmer will have created a substantial body of code potentially suitable for a portfolio, a showable record of what s/he can do. The built-from-scratch engine itself can be shown, with one or more games demonstrating its functionality, with the potential for an in-depth conversation (say, with a potential employer) about how, exactly, the engine and game(s) are implemented. All of this achievable by programming a game engine from scratch.

More specifically, the goals of this book are to provide an understanding of:

In order to accomplish these goals, this book:

  1. Gives detailed instructions on how to implement a game using Dragonfly.

  2. Provides an overview of the Dragonfly architecture.

  3. Provides the design of Dragonfly, in the form of header files with design rationale, presented incrementally in order of implementation.

  4. Details step-by-step how to fully implement Dragonfly following the design.

Development is supported in Microsoft Windows, Apple Macintosh or Linux, with platform specific differences illustrated, as needed.
