Seed Finder Mod
With Seed Finder Mod, a player can search for a Minecraft Java Edition world seed that places chosen structures and biomes near spawn.
What it does
The mod works from the Java Bedrock game's seed data: it finds seeds that match criteria a player sets, which can help with seed cracking and seed reversal. A player starts with a minimal criterion, such as a village within 100 blocks, and adds more later, for example a woodland mansion within 150 blocks of the previous structure, a badlands biome within 500 blocks, or 20% jungle with sparse bamboo. Changing criteria stops the current search, and an impossible set, such as an outpost within 100 blocks of a village, is reported as unmatched.
Seed Finder Mod adds a world type for this search. Once a seed matches, the new dimension is created with the overworld seed given, and the player can create a new world with the seed found or load it. A seed book holds the seed number and details of the criteria, and it can be kept in an ender chest for later use. The mod is open source under the MIT License and is published for Fabric only, across 1.19.2, 1.20 and 1.20.1, with 0.1.3 for 1.20.1 as the latest file.
Key features
Criteria-based seed search
Players set structures, biomes and distances, then run the next command to step through seeds that match.
Seed book
A book records the seed number and the search criteria, and it can be reopened while holding it in the main hand.
Teleport and structure check
The player can fly to a found seed's structure locations and move into a world built on that seed to confirm them.
Island seed search
A player who wants an island seed can set a large amount of ocean as a criterion and refine the search from there.
