About random...

[Caldaron]

hey folks!
I'm currently updating my weather script... to make the region and season setup much easier, but now i ran into a problem.

  def setup_regions_weather_cycle

    for region in @regions

      case region.name

      when "Outside"

        region.weather_transition = 200 # Frames

        region.weather_duration   = x   # Frames

      end

    end

whenever x comes along with rand(whatever) the duration of weather effects is still fix. So i want to call rand() without its seed.

I found a solution by putting the formluar into a string and call it with eval() when it's time to make the calculations.

But is there a better option?

to make it more obvious:
when g = rand(5) i want a random integer (0 to 4) returned whenever I call g, therefore i need to get rid of the seed in rand()

Bumpf!

Njargh!

I just want g = rand() to be always random, whenever i call it, dangit!

I am pretty sure it will always be random. If it is not, then just replace all your "g"s in your code with "rand(5)".

sry, but i think you misunderstood my problem, of course rand() is random, but after assigning it to to g it's fix.

g = rand(5) # => a random number from 0 to 4, this time 2

print g # => 2

print g # => 2

 

you got it now?

i want g, whenever i call it to return an integer from 0-4

define g as a method...

def g
return rand(5)
end

print g # => 0..4
