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())
