Updating events lua

[Rob (R8XFT)]

At the moment, I have an event which triggers at any point in Anno Domini, but I only want it to trigger once the civilization has discovered Nobility.

Currently, the code is this:

local Event_LapisLazuli = {}
    Event_LapisLazuli.Name = "TXT_KEY_EVENT_LAPIS_LAZULI"
	Event_LapisLazuli.Desc = "TXT_KEY_EVENT_LAPIS_LAZULI_DESC"
	Event_LapisLazuli.Weight = 5
	Event_LapisLazuli.CanFunc = (
		function(pPlayer)

			return true
		end
		)
	Event_LapisLazuli.Outcomes = {}

I'm adding a one-liner so it becomes this:

local Event_LapisLazuli = {}
    Event_LapisLazuli.Name = "TXT_KEY_EVENT_LAPIS_LAZULI"
	Event_LapisLazuli.Desc = "TXT_KEY_EVENT_LAPIS_LAZULI_DESC"
	Event_LapisLazuli.Weight = 5
	Event_LapisLazuli.CanFunc = (
		function(pPlayer)
		if not(Teams[pPlayer:GetTeam()]:IsHasTech(GameInfoTypes.TECH_NOBILITY)) then return false end

			return true
		end
		)
	Event_LapisLazuli.Outcomes = {}

Is that correct?
