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.

Loading scenes additively and asynchronously

Scenes can be loaded either to replace the current scene or can be loaded additively to add its contents to the current scene without unloading the preceding one. This can be toggled via the LoadSceneMode argument of the SceneManager.LoadScene() family of functions.

Another mode of scene loading is to complete it either synchronously or asynchronously, and there are good reasons to use both. Synchronous loading is the typical means of loading a scene by calling SceneManager.LoadScene(), where the main thread will block until the given scene completes loading. This normally results in poor user experience, as the game appears to freeze as the contents are loaded in (whether as a replacement or additively). This is best used if we want to get the player into the action as soon as possible, or we have no time to wait for scene objects...
