Function
Synopsis
RandomGenerator:setSeed( seed )
Arguments
number seed- The integer number with which you want to seed the randomization. Must be within the range of [1, 2^53].
Returns
Nothing.
Notes
Due to Lua's use of double-precision floating point numbers, values above 2^53 cannot be accurately represented. Use the other variant of this function if your seed will have a larger value.
Function
Combines two 32-bit integer numbers into a 64-bit integer value and sets the seed of the random number generator using the value.
Synopsis
RandomGenerator:setSeed( low, high )
Arguments
number low- The lower 32 bits of the seed value. Must be within the range of [0, 2^32 - 1].
number high- The higher 32 bits of the seed value. Must be within the range of [0, 2^32 - 1].
Returns
Nothing.
