Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "Since we don't need to set the initial variables, we can erase the Start() function."

A block of code is set as follows:

public void Update()
 if (Input.GetKeyDown (key))
 {
 EventSystem.current.SetSelectedGameObject(
this.gameObject);
 }}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

using UnityEngine.UI;
using UnityEngine.EventSystems;
using UnityEngine;
using System.Collections;

Any command-line input or output is written as follows:

C:\Program Files\Unity\Editor\Unity.exe

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Clicking the Next button moves you to the next screen."

Note
