Mr L64 started this library after he figured out an new way to find quad-witch huts and monuments. I added two new parts for finding interesting worlds. L64 also added this video https://www.youtube.com/watch?v=97OdqeiUfHw explaining the principle behind the program.
QuadHutFinder: Finds quad witch huts, by L64.
HutandMonumentFinder: The first looks for a quad huts/monuments combination. So the four is ether huts or monuments. What you most likely are looking for are 3 huts and one monument. But that's up to you. By EgU.
QuadHutMonFinder: This one first looks for a quad witch huts and if the monument would spawn in x-chunk higher then 16 and z-chunk higher then 16 around top left hut it will also check where and it the conditions are correct. If you are lucky it will spawn higher then 24,24 and be in the middle of the quad huts. By EgU.
There are also a small build script using ant. To choose what job you want to run change line 49 in build.xml.
java -jar dist/seedfinder.jar > seeds.txt
You can run as many copies as you have cores in your computer, more is pointless.
I'm not a java developer but I know how you should write java code. So if you are looking for nice well formed java-code. Please run away!! It you are looking for a program that finds cool seeds, this is the place to be, and if you do know how to write java code please do so and I will accept the pull request :)
