Unity 2017 Game Optimization - Second Edition

By: Chris Dickinson

Overview of this book

Unity is an awesome game development engine. Through its massive feature-set and ease-of-use, Unity helps put some of the best processing and rendering technology in the hands of hobbyists and professionals alike. This book shows you how to make your games fly with the recent version of Unity 2017, and demonstrates that high performance does not need to be limited to games with the biggest teams and budgets. Since nothing turns gamers away from a game faster than a poor user-experience, the book starts by explaining how to use the Unity Profiler to detect problems. You will learn how to use stopwatches, timers and logging methods to diagnose the problem. You will then explore techniques to improve performance through better programming practices. Moving on, you will then learn about Unity’s built-in batching processes; when they can be used to improve performance, and their limitations. Next, you will import your art assets using minimal space, CPU and memory at runtime, and discover some underused features and approaches for managing asset data. You will also improve graphics, particle system and shader performance with a series of tips and tricks to make the most of GPU parallel processing. You will then delve into the fundamental layers of the Unity3D engine to discuss some issues that may be difficult to understand without a strong knowledge of its inner-workings. The book also introduces you to the critical performance problems for VR projects and how to tackle them. By the end of the book, you will have learned to improve the development workflow by properly organizing assets and ways to instantiate assets as quickly and waste-free as possible via object pooling.

Editor hotkey tips

The Editor is rife with hotkeys that can aid rapid development, and it's worth checking out the documentation. However, let's be honest--nobody reads the manual until they need something specific from it, and so here are some of the most useful, yet lesser-known hotkeys available when playing with the Unity Editor.


In all cases, the Windows hotkey is listed. If the MacOS hotkey requires a different set of keystrokes, then it will be shown in parentheses.


GameObjects can be duplicated by selecting them in the Hierarchy window and pressing Ctrl + D (Command + D). New, empty GameObjects can be created using Ctrl + Shift + N (Command + Shift + N).

Press Ctrl + Shift + A (Command + Shift + A) to quickly open the Add Component menu. From there, you can type in the name of the Component you wish to add.

Scene window

Pressing Shift + F or double-tapping the F key will follow an object in the Scene window (assuming that the Scene window is open and visible), which can...
