local x, y = lume.vector(0, 10) -- Returns 10, 0 local x, y = lume.vector(0, 10) -- Returns 10, 0
``` ```
#### lume.seed([low [, high]])
Sets random seed. If using LOVE engine's math library, both `low` and `high`
arguments are used, else, only one argument is accepted.
#### lume.random([a [, b]]) #### lume.random([a [, b]])
Returns a random number between `a` and `b`. If only `a` is supplied a number Returns a random number between `a` and `b`. If only `a` is supplied a number
between `0` and `a` is returned. If no arguments are supplied a random number between `0` and `a` is returned. If no arguments are supplied a random number
