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.

Texture files

The terms texture and sprite often get confused in game development, so it's worth making the distinction: a texture is simply an image file, a big list of color data telling the interpreting program what color each pixel of the image should be, whereas a sprite can be seen as the 2D equivalent of a mesh—it defines how and where the image will appear in the game scene. Usually, a sprite is just a single quad (a pair of triangles combined to make a rectangular mesh) that renders flat against the current camera.

There are also things called sprite sheets, which are large collections of individual images contained within a larger texture file, commonly used to contain the animations of a 2D character. These files can be split apart by tools, such as Unity's Sprite Atlas tool, to form individual textures for the character's animated frames.
