Modular Game Engine Design

Abstract

The usage of software engineering principles in designing a game engine is discussed in this chapter using a simple tower defense game implemented using C# and the XNA Framework to illustrate usage of the engine. Essential functions, such as collision detection, input/output, graphics, object management, state management, and sound, will be implemented as independent units called managers. Because each manager is independent from the rest, essential development tasks such as implementing each manager and isolating bugs are much simpler.
