Time for action – linking your tutorial to your game

Your tutorial level is ready to play, but we still need a way to access it. We'll accomplish this by adding another button to your title screen directly underneath the start button. Perform the following steps to link the tutorial:

1. Open the scene named TitleScreen and double-click on the StartButton.cs script to open it in your code editor.

2. Add the following lines of code in your OnGUI function to create a tutorial button immediately below the start button:

   void OnGUI()
   {
     if(GUI.Button(new Rect(Screen.width / 2 – 50, Screen.height / 2 + 25, 100, 50), "Start"))
     {
       Application.LoadLevel("level1");
     }
   
     //create a tutorial button
     if(GUI.Button(new Rect(Screen.width / 2 – 50, Screen.height / 2 + 125, 100, 50), "Tutorial"))
     {
       Application.LoadLevel("TutorialScreen");
     }
   }

   Much like the start and reset buttons, the code for the tutorial button is uniform with the others; we only needed to edit the button text and the linked level...
