All you need is a copy of Unity 2018, which can be downloaded for free from http://www.unity3d.com.
If you wish to create your own image files, for the recipes in the Creating Maps and Materials, for example, you will also need an image editor, such as Adobe Photoshop, which can be found at http://www.photoshop.com, or GIMP, which is free and can be found at http://www.gimp.org.

You'll find the recipes assets and completed Unity projects for each chapter at: https://github.com/PacktPublishing/Unity-2018-Cookbook-Third-Edition.

You can either download these files as Zip archives or use free Git software to download (clone) these files. These GitHub repositories will be updated with any improvements.

We also have other code bundles from our rich catalog of books and videos available at https://github.com/PacktPublishing/. Check them out!

We also provide a PDF file that has color images of the screenshots/diagrams used in this book. You can download it here: https://www.packtpub.com/sites/default/files/downloads/Unity2018CookbookThirdEdition_ColorImages.pdf.

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Import file arrowCursor.png into your Unity project."

A block of code is set as follows:

using UnityEngine; 
using UnityEngine.UI; 

[RequireComponent(typeof(PlayerInventoryTotal))] 
public class PlayerInventoryDisplay : MonoBehaviour { 
   public Text starText; 
   public void OnChangeStarTotal(int numStars) { 
         string starMessage = "total stars = " + numStars; 
         starText.text = starMessage; 
   } 
}

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select System info from the Administration panel."
