Sets the seed of the random number generator using the specified integer number.
Contents
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.
Examples
Creates a new RandomGenerator object, sets the seed to the system clock's time, then generates a number between 1 and 100 inclusive. Note that the seed can be any number within the range of [0, 2^53 - 1].
function love.load()
rng = love.math.newRandomGenerator()
rng:setSeed(os.time())
randomNumber = rng:random(1,100)
end
