FSXA [C++] randomized variables

[Vitus]

Hi there,
I want to implement a radomize function to determine the weight of the passengers for my load manager. I tried to use the rand() function, but it seems like this doesn't work. What I tried is something like this:

FLOAT64 grd_pax_weight1 = 0.0;

void updatePayload()
{
  HRESULT hr;
  srand( (int) fs_time );

  grd_pax_weight1 = (((FLOAT64) rand() / 200 ) + 100);
}

the seeding value fs_time in this case is synchronized to the

E:LOCAL TIME,second

token variable before calling the updatePayload function.
I also tried to use a C++ time variable but that didn't work either, the result is always the same: the weight is set to a "random" number once, but when constantly updated, the number does only change after about a minute - then it is increased by exactly +1.

Do you have any idea how to get a real pseudo-random number?

Regards
Vitus

You should only call the srand function once, on startup, and then call just rand when you want a new random number.

Hey Tim,

that did the trick! Thanks for your help!
