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.

When to use the Command pattern

Here's a shortlist of possible uses for the Command pattern:

  • Undo: Implementing an undo/redo system that you find in most text and image editors.
  • Macro: A macro recording system with which players can record a sequence of attack or defensive combos. Then, assign them on an input key to execute them automatically.
  • Automation: Automate processes or behaviors by recording a set of commands that a bot will automatically and sequentially execute.

In conclusion, it's a good pattern for features related to storing, timing, and sequencing user inputs. And if you get very creative with it, you could create some compelling game systems and mechanics.

Design patterns are fun to use if you don't worry too much about staying true to the original academic descriptions. If you don't lose the original intent of the pattern while experimenting with it, you should retain its core benefits.
