Used to find Minecraft world seeds with certain loot in the desert temple chests.
Minecraft will attempt to create one temple per 512x512 block region, and if it's not a desert biome, it won't be there.
If the temple doesn't spawn because it's not the right biome, add 248 to the seed. This will leave the loot and temple location unchanged, but the biomes will be different. Keep doing this until you find a seed with the right biome.
Sometimes the loot generated in minecraft will be different than what is predicted by this program. This can happen if there is a mineshaft, village or stronghold in the same chunk. This should be pretty rare if searching in the 0, 0 region, but mineshafts are more common farther away from spawn, so you'll have a higher chance of getting false results.
The program is by default configured to search for 3 or more mending books in the temple in the 0, 0 region. This temple can be found between 0-384 on both the x and z axis. Feel free to modify it to suit your needs.
