Time for action – handling input

1. Add the following declarations to the declarations region of the Player class:

   private static Vector2 baseAngle = Vector2.Zero;
   private static Vector2 turretAngle = Vector2.Zero;
   private static float playerSpeed = 90f;

2. Add the methods to handle keyboard and gamepad input to the Player class:

   #region Input Handling
   private static Vector2 handleKeyboardMovement(KeyboardState keyState)
   {
       Vector2 keyMovement = Vector2.Zero;
       if (keyState.IsKeyDown(Keys.W))
           keyMovement.Y--;
   
       if (keyState.IsKeyDown(Keys.A))
           keyMovement.X--;
   
       if (keyState.IsKeyDown(Keys.S))
           keyMovement.Y++;
   
       if (keyState.IsKeyDown(Keys.D))
           keyMovement.X++;
   
       return keyMovement;
   }
   
   private static Vector2 handleGamePadMovement(GamePadState gamepadState)
   {
       return new Vector2(
           gamepadState.ThumbSticks.Left.X,
           -gamepadState.ThumbSticks.Left.Y);
   }
   
   private static Vector2 handleKeyboardShots(KeyboardState keyState)
   {
       Vector2 keyShots...
