Available since LÖVE 0.9.0
This function is not supported in earlier versions.

Generates a pseudo-random number in a platform independent manner.

Function

Get uniformly distributed pseudo-random real number within [0, 1).

Synopsis

number = RandomGenerator:random( )

Arguments

None.

Returns

number number
The pseudo-random number.

Function

Get uniformly distributed pseudo-random integer number within [1, max].

Synopsis

number = RandomGenerator:random( max )

Arguments

number max
The maximum possible value it should return.

Returns

number number
The pseudo-random integer number.

Function

Get uniformly distributed pseudo-random integer number within [min, max].

Synopsis

number = RandomGenerator:random( min, max )

Arguments

number min
The minimum possible value it should return.
number max
The maximum possible value it should return.

Returns

number number
The pseudo-random integer number.

Notes

When using the 2nd and 3rd variant, numbers passed will be rounded, thus, RandomGenerator:random(0, 76.767) may return 77
