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 weapon system

By default, every bike model in our game comes equipped with a front-mounted gun that fires laser beams. The player can use this weapon to destroy obstacles that might be in the way, and very skilled players can shoot at flying drones while doing wheelies. The player can also purchase various attachments that boost the basic stats of the bike's weapon, as illustrated in the following diagram:

Let's review a shortlist of potential attachments that the player could buy:

  • Injector: A plasma injector that amplifies the weapon's damage capacity.
  • Stabilizer: An attachment that reduces vibrations caused when the bike hits its top speed. It stabilizes the weapon's shooting mechanism and expands its range.
  • Cooler: A water-cooling system that attaches itself to the weapon's firing mechanism. It enhances the rate of fire and reduces the cool-down duration.

These examples are high...
