To get the most out of this book

Some familiarity with Unity would be helpful but is not essential. A basic understanding of C# or any other object-oriented programming knowledge is required. At the time of writing this book, the Unity exam is based on Unity version 2017.3. We'll go through the procedure of downloading and installing the software in Chapter 1, Setting Up and Structuring Our Project. If for any reason, you are using a later version of Unity, that shouldn't matter unless the book mentions where things may differ between versions.

Conventions used

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

CodeInText: Indicates code words in the text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "A Unity package is a single file that contains various assets that can be used in Unity in a similar manner to a .zip file."

A block of code is set as follows:

  void Start()
    {
        this.transform.localPosition = Vector3.zero;
        startPos = transform.position;
        Distance();
    }

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

          public class PlayerSpawner : MonoBehaviour
        

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: "To finally bake the lights, open the Lighting window by going to Window | Lighting | Settings. Once there, select the Global Maps tab."
