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.

Summary

Phew, that was an involved chapter (because why would performance optimization be easy, right?). But before you start looking for applicable spots to shoehorn the Flyweight pattern into your projects, let’s review some key topics. First, you’ll get the most out of the Flyweight pattern when you’re creating lots and lots of objects with both context-independent and -dependent data, and when those two data categories can be easily partitioned. The pattern will also come in handy when the context-dependent data can be computed rather than stored.

The Flyweight pattern has five components: the Flyweight interface, concrete Flyweights, unshared Flyweights, a Flyweight factory, and, of course, the client using it all. A clean flyweight interface is one that has operations that act on the object’s extrinsic state, acting as an injection point for any context-dependent information. Concrete flyweight objects implement the flyweight interface and store...
