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.

Adapting for concurrent state machines

Other than prototypes or extremely simple games, you’ll likely run into situations where you need to keep track of multiple objects with their own internal states. This problem can quickly become a rabbit hole of concurrency and interdependence, but it boils down to whether the current states are related or not. We’ll start by updating our example to deal with unrelated state machines and end the section with recommendations for handling dependent scenarios.

Imagine we wanted to add states for weather conditions – one for sunny days and one for cloudy days. If we used a single state machine context to manage two sets of states, we would need concrete states for each combination (battle states x weather states) to keep tracking a single internal state. In our example, four battle states quickly turn into eight battle/weather combination states, and that’s just with two weather options. What if we wanted a third...
