| This function is not supported in earlier versions. |
Generates a pseudo-random number in a platform independent manner. The default love.run seeds this function at startup, so you generally don't need to seed it yourself.
Contents
Function
Get uniformly distributed pseudo-random real number within [0, 1].
Synopsis
number = love.math.random( )
Arguments
None.
Returns
number number- The pseudo-random number.
Function
Get a uniformly distributed pseudo-random integer within [1, max].
Synopsis
number = love.math.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 within [min, max].
Synopsis
number = love.math.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.
Examples
Generates a number between 1 and 100 (both inclusive).
function love.load()
randomNumber = love.math.random(1, 100)
end
