Game Development Patterns with Unity 2021 - Second Edition

By: David Baron

Overview of this book

This book is written for every game developer ready to tackle the bigger picture and start working with advanced programming techniques and design patterns in Unity. Game Development Patterns with Unity 2021 is an introduction to the core principles of reusable software patterns and how to employ them to build components efficiently. In this second edition, you'll tackle design patterns with the help of a practical example; a playable racing game prototype where you’ll get to apply all your newfound knowledge. Notable updates also include a game design document (GDD), a Unity programming primer, and the downloadable source code of a complete prototype. Your journey will start by learning about overall design of the core game mechanics and systems. You’ll discover tried-and-tested software patterns to code essential components of a game in a structured manner, and start using classic design patterns to utilize Unity's unique API features. 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 book, the way you develop Unity games will change – you’ll adapt a more structured, scalable, and optimized process that will help you take the next step in your career.

Understanding the Service Locator pattern

Compared to more traditional patterns, the Service Locator pattern has less academic theory behind it and is very pragmatic in its overall design. As its name implies, its purpose is to locate services for a client. It achieves this by maintaining a central registry of objects that offer specific services.

Let's review a diagram of a typical Service Locator implementation:

As we can see, we could easily say that the Service Locator pattern is acting as a proxy between the clients (requestors) and the service providers, and this approach decouples them to a certain degree. A client will only need to call the Service Locator pattern when it has a dependency to resolve and needs access to a service. We could say that the Service Locator pattern is acting similarly to a waiter in a restaurant, taking orders from clients and acting as an intermediary between...
