How can you make zombies have their name and health not appear through walls?

Im making a game which has a maze and it would spoil the intensity of knowing what is behind a certain wall so i want to have the health bar and name hidden please help i cant find out how to hide it.

Hi...you will need to use a property call NameDisplayDistance and HealthDisplayDistance

game.Players.PlayerAdded:connect(function(player)--We are using the player added event and namming this function player
	player.CharacterAdded:connect(function(character)-- Now were adding the character
		local hum = character:WaitForChild("Humanoid") --now we will wait for child humanoid
               hum.NameDisplayDistance = 0 --sets these 2 propertys to 0 that will make it where you cant see it
               hum.HealthDisplayDistance = 0 
	end)
end)

Hope this helped let me know if it did..If it did and accepted answer would be appreciated
