Time for action – creating an interactive button

Now that you've created a cannon prefab, we can start writing scripts for it that use the OUYA controller's touchpad. The first functionality we'll add is an interactive button that makes the cannon fire a cannonball when it's tapped. Perform the following steps to add an interactive button:

1. Create a new script named CannonScript.cs in your Code folder and attach it to your Cannon prefab.

2. Open CannonScript.cs in your code editor.

3. Declare the following variables at the top of the CannonScript class definition, just before the Start function:

   private int buttonWidth;
   private int buttonHeight;
   private string buttonText;
   
   void Start()
   {
   
   }

4. Initialize each variable with values for our new button in the Start function. Give the button a width of 100, a height of 50, and a "Fire!" text label, as shown in the following code:

   Private int buttonWidth;
   private int buttonHeight;
   private string buttonText;
   
   Void Start()
   {
     buttonWidth = 100;
     buttonHeight...
