Design patterns in game development

This section will discuss common uses of design patterns in game development. We will explore using some of the patterns from the previous chapter, combined with the introduction of two new patterns (the flyweight pattern and the state pattern).

For this purpose, we’ll implement a hybrid of an action and strategy game, where the player controls a group of agents fighting another group of agents. As part of this game, we will use the following patterns:

• Singleton: The singleton pattern can be used to manage global resources across the game, such as the game manager, the audio system, and the input system.
