Unity Game Optimization - Third Edition

By: Dr. Davide Aversa, Chris Dickinson

Overview of this book

Unity engine comes with a great set of features to help you build high-performance games. This Unity book is your guide to optimizing various aspects of your game development, from game characters and scripts, right through to animations. You’ll explore techniques for writing better game scripts and learn how to optimize a game using Unity technologies such as ECS and the Burst compiler. The book will also help you manage third-party tooling used with the Unity ecosystem. You’ll also focus on the problems in the performance of large games and virtual reality (VR) projects in Unity, gaining insights into detecting performance issues and performing root cause analysis. As you progress, you’ll discover best practices for your Unity C# script code and get to grips with usage patterns. Later, you’ll be able to optimize audio resources and texture files, along with effectively storing and using resource files. You’ll then delve into the Rendering Pipeline and learn how to identify performance problems in the pipeline. In addition to this, you’ll learn how to optimize the memory and processing unit of Unity. Finally, you’ll cover tips and tricks used by Unity professionals to improve the project workflow. By the end of this book, you’ll have developed the skills you need to build interactive games using Unity and its components.

We've covered a humongous amount of theory and language concepts in this chapter, which have hopefully shed some light on how the internals of the Unity engine and C# language work. These tools try their best to spare us from the burden of complex memory management, but there is still a whole host of concerns we need to keep in mind as we develop our game. Between the compilation processes, multiple memory domains, the complexities of value types versus reference types, passing by value versus passing by reference, boxing, object pooling, and various quirks within the Unity API, you have a lot of things to worry about. However, with enough practice, you will learn to overcome them without needing to keep referring to giant tomes such as this!

With this chapter, we have covered all of the possible optimization areas in classic Unity. However, with the 2019.1 release...
