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 variables that we'll be using for now are Health, statePassive, stateAggressive, and stateDefensive."

A block of code is set as follows:

if (playerPosition == "triggerM") 
{ 
 transform.LookAt(playerSoldier); // Face the direction of the player 
 transform.position = Vector3.MoveTowards(transform.position, 
 buildingPosition.position, walkBack); 
 backwardsFire(); 
} 

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: "In Unity we click under the Layers button to expand more options, and then we click where it says Edit Layers...."
