In the didAddToEntity() method, add the following code below the line that reads updateHealth(0, forNode: componentNode):

if let _ = componentNode as? Player {
  hitAction = SKAction.playSoundFileNamed("player_hit",
                                          waitForCompletion: false)

  let playSound = SKAction.playSoundFileNamed("player_die" ...
