maybe_random2()

[Jk]

I'm trying to understand fight.cc, and all the to_hit functionality is calling this function. It's clearly not just random between a minimum and a maximum. Can anyone explain how maybe_random2() works (or direct me to where it is in the code)?

For instance:

  Code:

your_to_hit += maybe_random2(you.skills[wpn_skill] + 1, random_factor);

[galehar]

it's defined in random.cc. random_factor is a boolean. If it's true, the function returns the result of random2, else it returns the mean. random2(x) returns a random number between 0 and x - 1.
maybe_random2 is used because the to_hit functions can either return a randomized result (when called for actual fight) or a mean value for the interface to report the average player to_hit (although this functionality is currently disabled).
