Thanks for fast reply. :P
Anyways, I tried importing the std.c.stdlib and the std.c.time to use those exact same functions, but I got errors trying to use time(0) as a argument. Forgot to mention I tried that.

So, what would I put as an argument for rand_seed instead of time(0)? Can I just put in any number? Like 0?
BTW, don't use Tango.
