WebDescription. 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. WebJun 4, 2015 · 6. You're misunderstanding what random does: It's a pseudorandom number generator. This means that, given a specific seed, it will always give you the exact same sequence of numbers. Typically, you use a seed from an external source, e.g. use the current time as seed (WARNING: This is cryptologically dangerous!).

WebDec 27, 2024 · When called with two integers m and n, math.random returns a pseudo-random integer with uniform distribution in the range [m, n]. (The value n-m cannot be negative and must fit in a Lua integer.) The call math.random(n) is equivalent to math.random(1,n). This function is an interface to the underling pseudo-random generator … WebDec 5, 2024 · math.randomseed ( os.time () ) If Lua could get milliseconds from os.time () the init could be better done. Another thing to be aware of is truncation of the seed provided. math.randomseed will call the underlying C function srand which takes an unsigned integer value. Lua will cast the value of the seed to this format.
