Time for action – updating and drawing the player's ship

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

   Private Sub imposeMovementLimits()
       Dim location as Vector2 = playerSprite.Location
   
       If location.X < playerAreaLimit.X Then
           location.X = playerAreaLimit.X
       End If
   
       If location.X > 
           (playerAreaLimit.Right - playerSprite.Source.Width) Then
           location.X = 
               (playerAreaLimit.Right - playerSprite.Source.Width)
       End If
   
       If location.Y < playerAreaLimit.Y
           location.Y = playerAreaLimit.Y
       End If
   
       If location.Y > 
           (playerAreaLimit.Bottom - playerSprite.Source.Height) Then
           location.Y = 
               (playerAreaLimit.Bottom - playerSprite.Source.Height)
       End If
   
       playerSprite.Location = location
   End Sub

2. Add the Update() method to the PlayerManager class:

   Public Sub Update(gameTime As GameTime)
       PlayerShotManager.Update(gameTime)
   
       If Not Destroyed Then
