Learning Design Patterns with Unity

By: Harrison Ferrone

Overview of this book

Struggling to write maintainable and clean code for your Unity games? Look no further! Learning Design Patterns with Unity empowers you to harness the fullest potential of popular design patterns while building exciting Unity projects. Through hands-on game development, you'll master creational patterns like Prototype to efficiently spawn enemies and delve into behavioral patterns like Observer to create reactive game mechanics. As you progress, you'll also identify the negative impacts of bad architectural decisions and understand how to overcome them with simple but effective practices. By the end of this Unity 2023 book, the way you develop Unity games will change. You'll emerge not just as a more skilled Unity developer, but as a well-rounded software engineer equipped with industry-leading design patterns.

Converting Incompatible Classes with the Adapter Pattern

In the last chapter, we used the Decorator pattern to dynamically add new behavior to existing classes without using a traditional subclassing approach. In this chapter, we’ll stick with the idea of adding new behavior without touching an existing class, but this time, we’ll use interfaces to adapt existing incompatible classes to work together using the Adapter pattern (which is perfect when you need to force two unruly systems to play together nicely without overhauling either one).

Now, the Adapter pattern can be used for all kinds of situations, including porting an existing class into an interface your client code already uses, creating reusable classes that work with classes you haven’t even built yet, or bypassing a deep subclass hierarchy by adapting a single parent class. You can even use the pattern to converge properties from classes that don’t share any common class hierarchies! While...
