Time for action – responding to events

To enable our buttons to do something, we need to add code to the UIButton_Clicked() method by performing the following steps:

1. 1. Modify the UIButton_Clicked() method in the TankBattlesGame class to respond to button clicks as follows:

   void UIButton_Clicked(object sender, UIButtonArgs e)
   {
       int playerNumber = int.Parse(e.ID.Substring(1, 1)) - 1;
       string buttonName = e.ID.Substring(2);
   
       switch (buttonName)
       {
           case "Left":
               tanks[playerNumber].TurretRotation += 0.01f;
               break;
   
           case "Right":
               tanks[playerNumber].TurretRotation -= 0.01f;
               break;
   
           case "Up":
               tanks[playerNumber].GunElevation -= 0.01f;
               break;
   
           case "Down":
               tanks[playerNumber].GunElevation += 0.01f;
               break;
   
           case "Fire":
               break;
       }
   }

2. 2. In the User Interface region of the TankBattlesGame class, add a helper method for updating the contents...
