RandomGenerator:getState
| Available since LÖVE 0.9.1 |
| This function is not supported in earlier versions. |
Gets the current state of the random number generator. This returns an opaque implementation-dependent string which is only useful for later use with RandomGenerator:setState.
This is different from RandomGenerator:getSeed in that getState gets the RandomGenerator's current state, whereas getSeed gets the previously set seed number.
Function
Synopsis
state = RandomGenerator:getState( )
Arguments
None.
Returns
string state- The current state of the RandomGenerator object, represented as a string.
Notes
The value of the state string does not depend on the current operating system.
Examples
rng = love.math.newRandomGenerator(os.time())
for i=1, 100 do
-- Use some random numbers.
rng:random()
end
-- Make a new RandomGenerator and set its state to the current state of the first one.
rng2 = love.math.newRandomGenerator()
rng2:setState(rng:getState())
-- Both 'rng' and 'rng2' will now give the same results.
assert(rng:random() == rng2:random())
for i=1, 100 do
-- Use some random numbers.
rng:random()
end
-- Make a new RandomGenerator and set its state to the current state of the first one.
rng2 = love.math.newRandomGenerator()
rng2:setState(rng:getState())
-- Both 'rng' and 'rng2' will now give the same results.
assert(rng:random() == rng2:random())
