how can i call a function by a string?

[Seraphim8400]

i try like this

stemp = stemp .. "_HM" .. "1";
        print(stemp);
        _G[stemp]();

but log

HistoricalEnd: sino_HM1
Runtime Error: [string "Historical end/HistoricalEnd.lua"]:140: attempt to index global '_G' (a nil value)

i try another way

loadstring(stemp .. "()")();

then it error too
Runtime Error: [string "Historical end/HistoricalEnd.lua"]:140: attempt to call global 'loadstring' (a nil value)

so how can i call function sino_HM1() by a string value "sino_HM1"?

theres a bunch of lua stuff blocked by the game, loadstring must be one of these

i think so
but how can i do a operation like this?

 

[smellymummy]

do you mean something like this

local tbl = { ab = function(a) print(a); end, }; 

local a = "a"; 
local b = "b"; 

local string = a .. b; 

tbl[string]("hello");
