math.randomseed
Seeds the random number generator
Prototype
math.randomseed (n)Description
Seeds the random number generator with an integer. Re-seed with the same number to regenerate the same sequences by calling math.random.
Seeding with os.time () is a common technique to make random numbers different each time. Be aware however that for cryptographic purposes, the time of day is hardly a secret.

math.randomseed (44) -- fixed random seed
math.randomseed (os.time ()) -- randomize from whatever the time is
