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.

Managing Game Events with the Event Bus

The Event Bus acts as a central hub that manages a specific list of global events that objects can choose to subscribe to or publish. It's the most straightforward pattern related to event managing that I have in my toolbox. It reduces the process of assigning the role of subscriber or publisher to an object into a single line of code. As you can imagine, this can be beneficial when you need results quickly. But like most simple solutions, it has some drawbacks and limitations, which we will explore further on.

In the code example presented in this chapter, we will use the Event Bus to broadcast specific race events to components that need to listen for changes in the overall state of the race. But it's essential to keep in mind; I'm proposing using the Event Bus as a solution for managing global race events because of its...
