random()

float love::math::random	(	float	min,
		float	max
	)

Get uniformly distributed pseudo-random number, between the given numbers.

Parameters

min	(0.0f) The minimum value. Can be a double, float, or int.
max	(1.0f) The max value. Can be a double, float, or int.

Returns

A number between the two given min and max values.

love.math.random(5, 10) // 5-10
love.math.random(10)    // 0-10
love.math.random()      // 0.0f-1.0f

setRandomSeed() [1/2]

math& love::math::setRandomSeed	(	int	min,
		int	max
	)

Sets the random seed to a random seed between the given min and max values.

Parameters

min	The lower 32 bits of the seed value.
max	The higher 32 bits of the seed value.

Returns

The math module, to allow for method chaining.

love.math.getRandomSeed

setRandomSeed() [2/2]

math& love::math::setRandomSeed

(

int

seed

)

Sets the seed of the random number generator.

Parameters

seed	The integer number with which you want to seed the randomization.

Returns

The math module, to allow for method chaining.
