Unity Game Optimization - Third Edition

By: Dr. Davide Aversa, 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.

Materials and shaders

Render State in Unity is essentially exposed to us via materials. Materials are containers around shaders, short programs that define how the GPU should render incoming vertex and texture data. A shader on its own does not have the necessary knowledge of the state to accomplish anything of value. A shader requires input such as diffuse textures, normal maps, and lighting information, and effectively dictates what Render State variables need to be set in order to render the incoming data.

Shaders are named this way because, many years ago, their original implementation was to only handle the lighting and shading of an object (applying shadows where originally there were none). Their purpose has grown enormously since then, and now they have the much more generic purpose of being a programmable access point to many different kinds of parallel tasks, but the...
