WyWF

Players type a description of the world they want into the seed field on the world creation screen, then confirm the creation step. The mod reads the text, picks out recognizable terms in Russian or English, and starts an offline search that scans seeds around a chosen center. Each candidate is tested against the placement math for structures, biomes and spawn conditions, and a match is presented before any world is generated.

The search covers surface biomes such as ocean, desert, forest and cave biomes, village variants including plains and desert villages, and structures such as plains village and desert temple. A spawn block marks the player's approximate spawn point on the map, and the selected spawn is used once the world is generated. Slow queries stop early after a few candidates are collected, and candidates are re-checked exhaustively before being shown. Biome lookups use a fast native library when one is available and fall back to pure Java otherwise.

WyWF is client and server, so the server and every player need it. It is published for Fabric only, across 16 release versions 1.21.1 – 26.3, under the Apache License 2.0, and the source code is open source. Builds for the 26.x line depend on Java 25.
