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 are shown as follows: "Declare a new Difficulty variable to store current difficulty."

A block of code is set as follows:

public void OnDifficultyChange() 
{
  //If Difficulty changes to Normal, set Difficulties.Normal
  if(UIPopupList.current.value == "Normal")
    Difficulty = Difficulties.Normal;
  //Otherwise, set it to Hard
  else Difficulty = Difficulties.Hard;
}

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

//We will need the Slider
UISlider slider;

void Awake ()
{
  //Get the Slider
  slider = GetComponent<UISlider>();
  //Set the Slider's value to last saved volume
  slider.value = NGUITools.soundVolume;
}

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: "You can now click on the Create Your UI button."
