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 global race events

The project we are working on is a racing game, and most races are structured in stages. The following is a shortlist of typical racing stages: 

  • Countdown: At this stage, the bike is stopped behind the start line while a countdown timer is running down.
  • Race start: Once the clock hits zero, the green light signal is turned on, and the bike moves forward on the track.
  • Race finish: The moment the player crosses the finish line, the race is over.

In between the start and finish of the race, certain events can be triggered that could change the current state of the race:

  • Race pause: The player could pause the game while still racing.
  • Race quit: The player could quit the race at any time.
  • Race stop: The race could stop suddenly if the player is involved in a fatal crash.

So we want to broadcast a notification that signals the occurrence of each stage of the race and any other important event in between that will change the overall state of the race. This...
