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 Object Pool pattern

These are some of the benefits of the Object Pool pattern:

  • Predictable memory usage: With the Object Pool, we can allocate in a predictable manner some memory to hold a specific amount of instances of certain type of object.
  • Performance boost: By having objects already initialized in memory, you avoid the loading cost of initializing new ones.

These are some potential drawbacks of the Object Pool pattern:

  • Layering on already managed memory: Some people criticize the Object Pool pattern as being unnecessary in most cases because modern managed programming languages such as C# already optimally control memory allocation. However, this statement might be true in some contexts but false in others.
  • Unpredictable object states: A potential pitfall of the Object Pool pattern is that if it is incorrectly handled, objects can be returned to the pool in their current state instead of their initial one. This situation can be an issue...
