No Damage God Mode

[Epsilon_Pegas]

Hello Facepunch. Recently, I've been looking around to try and find some manner script that would prevent players in god mode from being able to damage other players. I was given the following script a few weeks back, but it didn't seem to function properly for me.

local PMETA = FindMetaTable("Player")

function PMETA:IsGod()
	return self:GetNWBool("GodMode")
end

function PMETA:SetGod()
	if SERVER then
		if !self:IsGod() then
			self:GodEnable()
			self:SetNWBool("GodMode",true)
		else
			self:GodDisable()
			self:SetNWBool("GodMode",false)
		end
	end
end

hook.Add("PlayerShouldTakeDamage","DisableDamageFromGod",function(vic,atk)
	if atk:IsGod() then return false end
end)

Since I possess only a basic understanding of how Lua works in Garry's Mod, I was hoping that one of you might be able to help me diagnose the problem. Thanks in advance.

[lua]
local plyMeta = FindMetaTable("Player")

function plyMeta:IsGod()
return self._godMode -- the function is probably only used on the server
end -- no point in networking a boolean value

plyMeta.oldGodEnable = plyMeta.oldGodEnable or plyMeta.GodEnable
plyMeta.oldGodDisable = plyMeta.oldGodDisable or plyMeta.GodDisable

function plyMeta:GodEnable()
self._godMode = true
self:oldGodEnable()
end

function plyMeta:GodDisable()
self._godMode = false
self:oldGodDisable()
end

hook.Add("PlayerShouldTakeDamage","disable_damage_from_god",function(_,p)
if IsValid(p) and p:IsPlayer() and p:IsGod() then -- players can take damage from non-player entities too
return false
end
end)
