Chapter 2. Scripting
To create your gameâs behavior, youâll need to write code. Code in Unity is written in C# (pronounced âC sharpâ), a language developed by Microsoft that has an excellent open source implementation, which Unity makes extensive use of.

This book isnât going to try to give you a complete guide to programming, or a complete guide to programming in C#âthatâd be a whole other book. Instead, weâll show you how to write scripts for use in Unity, using C# as the language.
If youâre interested in learning C# in a broader sense, we recommend C# 7.0 in a Nutshell (OâReilly), by Ben and Joseph Albahari.
2.1 Working with MonoBehaviours
You want to add scripts to your game objects, so that you can customize their behavior through code.
Unity game objects are containers for components. A
MonoBehaviourânamed for Mono, the scripting runtime that Unity usesâis a script component; when a
MonoBehaviour is attached to a game object, it participates in the gameâs update loop and gives you the opportunity to run code every frame.
To add code to a game object, you create a new
MonoBehaviour script and attach it to the game object as a component. This means that youâll need a game object to use:
Create a new cube by opening the GameObject menu and choosing 3D Object â Cube.
Use the Move tool to position the ...
