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.

Benefits and drawbacks of the Command pattern

These are some of the benefits of the Command pattern:

  • Decoupling: The pattern permits the decoupling of the object that invokes the operation from the one that knows how to execute it. This layer of separation allows the addition of an intermediary that will be able to bookkeep and sequence operations.
  • Sequencing: The Command pattern facilitates the process of queuing user inputs, which permits the implementation of undo/redo features, macros, and command queues.

This is a potential drawback of the Command pattern:

  • Complexity: It takes numerous classes to implement this pattern as each command is a class in itself. And it takes a good understanding of the pattern to maintain code built with it. In most cases, this is not an issue, but if you are using the Command pattern without a specific goal in mind, it can become an unnecessary layer of complexity and verbosity in your code base.
