scripting trouble: script where if someone dies then everyone dies?

i learned how to make a script for a brick to kill you... but i’m having trouble to make it where if someone dies then everyone dies and respawns, so how do i do it or how do i start off? any help is appreciated!

I would advise you look into the Player.CharacterAdded event, the Humanoid.Died event, and the Players.PlayerAdded event. You can use these to help detect when someone has died.

**Put a local script into StarterGui: **

wait()

local player = game.Players.LocalPlayer
local chr = player.Character
local humanoid = chr:WaitForChild("Humanoid")

humanoid.Died:Connect(function()
	for i,v in pairs(game.Players:GetPlayers()) do
		v.Character:WaitForChild("Humanoid").Health = 0
	end
end)

Hope this helps!
