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

If you’re reading this, then you’ve made it through the Strategy pattern, which should really be called the delegation pattern! We have a working prototype that can do similar work (sorting and behavior actions) in different ways while also allowing us to dynamically switch how the work is done at any time. Our system also lets us work with ScriptableObject assets instead of hardcoding our concrete strategies, and everything is nicely decoupled using interfaces (not bad for an afternoon of code)!

When using the Strategy pattern, remember that each family or grouping of strategies will need their own strategy interface, concrete strategies, and context. It also pays to think about how your project gets each concrete strategy the data it needs – it can be passed in from the context, stored in the strategy interface, or a mix of both. The only potential coupling downside with this pattern is that the client needs to know about all the available concrete...
