Created page with "{{PageHeaderChild|LUA|GetServerVariable}} == GetServerVariable() == Gets the value of the server variable == Syntax == var = GetServerVariable(param1) == Parameters == ; Requ..."

New page

{{PageHeaderChild|LUA|GetServerVariable}}

== GetServerVariable() ==
Gets the value of the server variable

== Syntax ==
var = GetServerVariable(param1)

== Parameters ==
; Required - ''param1'' (String)
: ''param1'' is the name of the server variable to get

== Returns ==
; String

== Usage ==
<pre>
function hailed(NPC, Spawn)
local var = tonumber(GetServerVariable("Quest1_Global_Complete_Count"))

if var == nil or var <= 4000 then
OfferQuest(Spawn, Quest1)
else
OfferQuest(Spawn, Quest2)
end
end
</pre>

This will offer the player a different quest if the server variable Quest1_Global_Complete_Count is less then or equal to 4000
