Time for action – overloading the level restart

Let's add an overloaded version of RestartLevel():

1. Open up Utilities and add the following code:

 public static class Utilities 
 {
     public static int playerDeaths = 0;
 
     public static void RestartLevel()
     {
         SceneManager.LoadScene(0);
         Time.timeScale = 1.0f;
     }
 
     // 1
     public static bool RestartLevel(int sceneIndex) 
      {
         // 2
         SceneManager.LoadScene(sceneIndex);
         Time.timeScale = 1.0f;
 
         // 3
         return true;
     }
 } 

2. Open GameBehavior and update one of the calls to Utilities.RestartLevel() in the OnGUI() method to the following:

if (showWinScreen)
 {
   if (GUI.Button(new Rect(Screen.width/2 - 100, 
      Screen.height/2 - 50, 200, 100), "YOU WON!"))
   {
     // 4
     Utilities.RestartLevel(0);
   }
 }

Let's break down the code:

1. First, it declares an overloaded version of the RestartLevel() method that takes in an int parameter and returns...
