How do i make a message when a player dies???

Hello, I see you are asking about the .Died function.

Here is an example of what you are looking for:

IN A SERVER SCRIPT

game.Players.PlayerAdded:connect(function(plr)
	plr.CharacterAdded:connect(function(char)
		repeat wait() until char.Humanoid
		local humanoid = char.Humanoid
	
		local function died()
			local hint = Instance.new("Hint")
			hint.Parent = game.Workspace
			hint.Text = plr.Name.." has died!"
			wait(5)
			hint:destroy()
		end

		humanoid.Died:connect(died)
	end)
end)

Here is what we used:

Local functions are basically functions inside functions, which is what the died function is.
