The setting of random seeds in Lua

1. Common methods:

Math.randomseed (Os.time ()) print (Math.random ())

2. Methods of Improvement:

Math.randomseed (ToString (Os.time ()): Reverse (): Sub (1, 6)) print (Math.random ())

3. Methods for further improvement:

Local socket = require ("socket")--need to use Luasocket Library local function get_seed ()        Local t = String.Format ("%f", Socket.gett IME ())        Local st = string.sub (T, String.find (t, "%.") + 1,-1)         return Tonumber (String.reverse (ST)) Endmath.randomseed (Get_seed ()) print (Math.random ())
