love.math.setRandomState
Sets the current state of the random number generator. The value used as an argument for this function is an opaque implementation-dependent string and should only originate from a previous call to love.math.getRandomState.

This is different from love.math.setRandomSeed in that setRandomState directly sets the random number generator's current implementation-dependent state, whereas setRandomSeed gives it a new seed value.
love.math.setRandomState( state )
state string The new state of the random number generator, represented as a string. This should originate from a previous call to love.math.getRandomState.
