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.

Managing Performance and Memory with Object Pooling

In the last chapter, we created a pipeline for assembling tanks and drones using the Builder pattern and Unity’s ScriptableObjects. In this chapter, we’ll switch gears and focus on increasing performance and managing memory allocation when creating new objects with the Object Pool pattern. This approach is twofold; first, you get to control when batches of objects are instantiated, and second, you control how they are stored in a reusable pool that you can grab from whenever you want (without any additional CPU overhead).

By default, Unity already does a great job of allocating, managing, and cleaning up memory usage during object instantiation. So, why would we spend our time reinventing the wheel here? Well, even though Unity has our backs on this topic, you’ll find that pooling and reusing objects instead of creating and destroying them over and over has a marked performance impact. So, just because object...
