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 power-up mechanic

As mentioned at the beginning of this chapter, the power-up is a staple of video games. And it's a core ingredient of our game. But first, we will review some of the key specifications of our mechanic:

  • Granularity: Our power-up entities will have the ability to boost multiple properties at the same time. For example, we could have a power-up that increases offensive capabilities such as the primary weapon's range while repairing the front-facing shield.
  • Time: The power-up effects are not temporal so they don't expire after a certain amount of time. And the benefits of the next power-up are added on top of the previous one until they hit the maximum settings of the boosted properties.

Take note that these specifications are limited to the following code example, but are not final. We could easily make the benefits of a power-up temporary or change the overall design of the mechanic with slight changes to the code example presented in...
