LUA - GetServerVariable

Return to: LUA | Tutorials | Portal | Forum | Project Manager | Bug Tracker


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

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

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

Notes

If the server variable is not a number then tonumber returns nil, hence the check for nil.

Also, if the value is a string, for example a 'motd' variable, or an existing non 'LUA_' prefix variable_name, it will return as NULL. Use GetVariableValue() for those criteria instead.
