Conventions

In this book, you will find a number of styles of text 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: "We can include other contexts through the use of the include directive."

A block of code is set as follows:

1 int integerVariable = 42;
2 
3 int interger function (int inInteger) {
4    return inInteger + 42;
5 } 

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

1 int integerVariable = 42;
2 
3 int interger function (int inInteger) {
4     return inInteger + 42;
5 } 

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Click on the Add component button and add Box 2D Collider and Sprite Renderer components".

Note
