Is there a GaussianRand() function?

Hi,
I’m looking for a rand() function that does not return uniformly distributed random values, but Gaussian distributed random values. Like FMath:GaussianRandInRange(int a, int b) or something. Does this exist somewhere?

Anyone? …

There seems to be none, atleast i didn’t find it. Try implement something yourselfs, there definitely some C++ algorithms somewhere laying on internet, just watch out on licences

Isn’t c++11’s std::normal_distribution, gaussian?

Yeah, im 95% certain normal_distribution is gaussian. I have some code within 's Victory Plugin that could be of use.

Hey, yes, I also think Gaussian distribution and normal distribution are the same thing, whereas uniform distribution is what you get, when you use
FMath::FRandRange(0, 20)
