Cruising the API and I see that grandom is deprecated. Does random offer a similar functionality considering standard deviation etc? Or is there some other function I should be using for similar results?

 

EDIT: Perhaps I should use this:

yes it will

I seem to remember it was deprecated because it wasn't functioning correctly; the API now only supports linear random. That being said, it's not too hard to come up with your own equivalent using https://docs.oracle.com/javase/7/docs/api/java/util/Random.html#nextGaussian()

Make sure to take into account far-edge generations though!

I deprecated it because it doesn't create a normal distribution, it only creates the positive half of the bell curve. My official solution was/is the following:

 

 public static int gRandom(int mean, double stdDeviation)
            throws IllegalArgumentException {
        if (mean < 0)
            throw new IllegalArgumentException("Mean can't be lower than 0!");
        double max = stdDeviation * 3;
        int result;
        do {
            result = Math.toIntExact(Math.round(random.nextGaussian() * stdDeviation + mean));
        } while (Math.abs(result - mean) > max);
        return result;
    }
