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: "The main Unity callback for application updates is the Update() function."

A block of code is set as follows:

public class TestComponent : MonoBehaviour {
    void Update() {
        if (Input.GetKeyDown(KeyCode.Space)) {
            PerformProfilingTest();
        }
    }
}

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 TestComponent : MonoBehaviour {
    void Update() {
        if (Input.GetKeyDown(KeyCode.Space)) {
            PerformProfilingTest();
        }
    }
}

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: "The threshold value for the sleeping state can be modified under Edit | Project Settings | Physics | Sleep Threshold."

Note

Warnings or important notes appear in a box like this.
