LUA Tutorial: String to function

-- Convert string to function

-- Setup:
gSetup = {
    -- function (string), function arguments:
    {"TextPrintString",{"Hello World",2,1}},
    {"ClockSet",{8,45}},
    {"PlayerKilled",{""}},
    {"PedSetWeapon",{gPlayer,305,50}},
    {"ForceStartMission",{"6_B"}},
}
-- Main function:
function main()
    Wait(450)

    while true do
        if IsButtonBeingPressed(3,0) then
            -- Random call:
            local Random = math.random(1,table.getn(gSetup))
            _G[gSetup[Random][1]](unpack(gSetup[Random][2]))
        end

        Wait(0)
    end
end
