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.

Designing a bike engine

We are not aiming to implement a complete simulation of an actual gas engine for a bike; this will take too long and demands an in-depth understanding of the physics and mechanics of a real-world engine. But we will aim to simulate, to a minimal degree, some standard components of a high-speed vehicle's motor. So first, let's break down the expected behavior of each part of our engine, as follows:

  • Cooling system: The cooling system is responsible for making sure the engine is not overheating. When the turbocharger is activated, the cooling system shuts down during a turbocharge. This behavior means that if the player overuses the turbocharger, this can overheat the engine, and in consequence, the engine will stop or explode and the bike will stop moving.
  • Fuel pump: This component is responsible for managing the fuel consumption of the bike. It knows the amount of gas remaining and stops the engine if it runs out of it.
  • Turbocharger: If the turbocharger...
