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.

It's always a good idea to organize our scenes using empty GameObjects and use them as parents for a group of objects while naming them something sensible for that group. The only drawback to this method is that the empty object's transform is included during position or rotation changes and is included during recalculations. As we know, reparenting GameObject to another transform has its own costs. Proper object referencing, transform change caching, and/or use of localPosition/localRotation can be used to solve some of these problems adequately. In almost all cases, the benefits of having a workflow from scene organization are significantly more valuable than such trivial performance losses.

Animator Override Controllers were introduced way back in Unity v4.3 but tend...
