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.

Global Access with the Service Locator Pattern

In the last chapter, we used the Flyweight pattern to create a resource-efficient sharing system for objects created in large (sometimes massive) batches. In this chapter, we’ll circle back to the very first topic of this book, global access, but instead of a Singleton solution, we’ll explore what the Service Locator pattern has to offer.

Scenarios where the Service Locator pattern shines are eerily similar to areas where a Singleton would be a potential solution – allowing a very select few services or systems to be accessible anywhere in your project. While this kind of freewheeling access should be extremely limited (for coupling and safety reasons we’ll discuss a little later), there are some use cases where a global service is a necessity (logging and data persistence come to mind). Think of the service locator as a wrapper for classes you would typically consider making into singletons – a...
