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.

Pattern strategies and optimizations

If you decide the original Observer pattern is right for a portion, or the entirety, of your project, you’ll need more clarity in three key areas:

  • Choosing the kind of information the subject sends to observers, which is commonly referred to as the communication strategy
  • Specifying different events that subjects can send out and choosing which events your observers listen for and act on
  • Managing object references and memory leaks when subjects or observers are destroyed or disabled

While I’ve marked this section as pattern variations and optimizations, incorporating these three topics into your design pattern code is mandatory if you want an efficient, scalable, and safe project.

I can’t stress this enough, especially the object cleanup; ghost objects and memory leaks are no joke and are extremely hard to debug in the decoupled subject-listener structure.

Choosing a communication...
