Map Seed

Does anyone know what method NMS code uses to set the map seed string to a long and pass into the WorldCreator? Ive got a map that has a string for a seed, but i need it to be converted into a long to work with the world creator. I figured it may be just hashing the string, but i dont wanna be wrong. (nor do i know how i would check)

Code:java

String s = this.propertyManager.getString("level-seed", "");
long k = (new Random()).nextLong();
if (s.length() > 0) {
    try {
        long l = Long.parseLong(s);
 
        if (l != 0L) {
            k = l;
        }
    } catch (NumberFormatException numberformatexception) {
        k = (long) s.hashCode();
    }
}

k would be the seed. It would default to a random long, take the String as seed if the seed can be converted to a long. If not, it would get, indeed, the hash.

 

Yeah i found that after i had posted this. Question though, when i didnt define a seed in my world creator, it would always generate the map fractally, is this because every reboot it would choose a different seed?

 

Umm... no? wouldn't a world save the seed?

 

I mean with my multiworld system. Based on what ive seen, whenever i try to load additional worlds, if i dont save the seed to file, and specify the seed, it fragments the world.

 

Mmh weird

 

I think the reason is that the seed for the main world is saved to the preferences file, while any additional worlds loaded (not typical with minecraft) are given a random seed if you dont provide one.
