Unable to harm/kill other players on my own server

I created a fivem server so I could play online with mods with my friend, but ingame I’m unable to harm any real player. I can cause damage to other entities, but I’m unable to shot a bullet at an online player when I am over them. Does anyone know how I can fix this issue.

You could use this, or take it and turn it into something more

Citizen.CreateThread(function()
	while true do
		Citizen.Wait(0)
		for i = 0,63 do
			if NetworkIsPlayerConnected(i) then
				if GetPlayerPed(i) ~= nil then
					SetCanAttackFriendly(GetPlayerPed(i), true, true)
					NetworkSetFriendlyFireOption(true)
				end
			end
		end
	end
end)

Thanks your script got it working
