This function is not supported in earlier versions. |
Generates a pseudo-random number in a platform independent manner. This function is seeded 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
Notes
When using the 2nd and 3rd variant, numbers passed will be rounded, thus, love.math.random(0, 76.767)
may return 77
