What just happened?

This heading explains the working of tasks or instructions that you have just completed.

You will also find some other learning aids in the book, including:

Pop quiz – heading

These are short multiple choice questions intended to help you test your own understanding.

Have a go hero – heading

These set practical challenges and give you ideas for experimenting with what you have learned.

You will also 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 are shown as follows: "We can play the example game that comes with it to get an idea of what the UDK can do by going into C:\UDK\UDK-AwesomeGame\Binaries\Win32 (or Win64 if we have a 64-bit operating system) and running UDK.exe"

A block of code is set as follows:

Class AwesomeActor extends Actor
   placeable;
defaultproperties
{
   Begin Object Class=SpriteComponent Name=Sprite
      Sprite=Texture2D'EditorResources.S_NavP'
   End Object
   Components.Add(Sprite)
}

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

Begin Object Class=SpriteComponent Name=Sprite
   Sprite=Texture2D'EditorResources.S_NavP'
HiddenGame=True
End Object
Components.Add(Sprite)

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: "Let's click on Return to Desktop for now."
