Time for action – handling user input

1. Add the FireShot() helper method to the PlayerManager class:

   private void FireShot()
   {
       if (shotTimer >= minShotTimer)
       {
           PlayerShotManager.FireShot(
               playerSprite.Location + gunOffset,
               new Vector2(0, -1),
               true);
           shotTimer = 0.0f;
       }
   }

2. Add the HandleKeyboardInput() helper method to the PlayerManager class:

   private void HandleKeyboardInput(KeyboardState keyState)
   {
       if (keyState.IsKeyDown(Keys.Up))
       {
           playerSprite.Velocity += new Vector2(0, -1);
       }
   
       if (keyState.IsKeyDown(Keys.Down))
       {
           playerSprite.Velocity += new Vector2(0, 1);
       }
   
       if (keyState.IsKeyDown(Keys.Left))
       {
           playerSprite.Velocity += new Vector2(-1, 0);
       }
   
       if (keyState.IsKeyDown(Keys.Right))
       {
           playerSprite.Velocity += new Vector2(1, 0);
       }
   
       if (keyState.IsKeyDown(Keys.Space))
       {
           FireShot();
       }
   }
