WyWF

What you Want to Find - Minecraft seed finder mod that searches for vanilla seeds matching the biomes, structures and spawn conditions you describe - before the world is created. Describe the world you want, press Create, and the mod searches offline for a matching seed.

Type what you want your world to be like — get a seed that matches.

Type a description into the Seed field, for example:

village near warm ocean       mansion dark forest
desert temple in desert       near deep dark
spawn on sand                 some 4 village
never plains village          only desert pyramid
between 500 to 800 village   spawn on any solid

When you press Create New World, the mod parses the text and, if it contains recognized keywords, opens a search screen. It scans seeds around your chosen center (spawn or origin), locates structures from placement math and samples biomes with a fast native library when available (with a pure-Java fallback). When a seed matches, the world is created with it. The red dot indicates the player's approximate spawn point (the player's spawn point is selected after the world has been generated):

Keywords are recognized in Russian and English, with many synonyms.

Modifier (EN / RU)	Meaning
(none)	present within the default radius
near / рядом, возле…	within ~200 blocks
in / в, на…	within ~64 blocks
far / далеко, вдали…	far away (~500–1000 blocks)
some N / несколько, много…	N or more structures nearby
only / только, лишь, одна…	exactly one structure nearby
between 500 to 800 / между, от…	structure within a distance range
under / под, снизу	the surface biome at that spot
no, not, without, never / нет, не, без	must NOT be present

• Biomes: surface biomes (ocean, desert, forest, …) and cave biomes (deep dark, lush caves, dripstone caves, sulfur caves — with near or under).
• Structures: village (and village_plains/desert/… variants), desert pyramid, jungle temple, swamp hut, igloo, mansion, monument, shipwreck, outpost, mineshaft, ocean ruins, buried treasure, trail ruins, ancient city, trial chambers, ruined portal, stronghold, nether fortress/bastion/fossil, and more. Nether checks use a separate nether generator.
• Compound terms: plains village → village_plains, desert temple → desert_pyramid, snowy village → village_snowy, etc.
• Spawn block: find seeds by the block you stand on — spawn on sand, on the stone block, на блоке песок, or any solid block.
• Search center: check at spawn (default) or origin (0, 0).

For slow queries the search stops early (after collecting a few candidates) so you get a result faster. Every candidate is re-checked exhaustively before it is shown.

Normal play logs almost nothing; run with -Dwywf.debug=true for the full per-search log when reporting a bug.

• Objects (tree, water, lava) are recognized but not searched yet.
• The 26.x jars require Minecraft 26.x and Java 25; the 1.21.x jar (version 1.4.1) requires Minecraft 1.21.x and Java 21.

The mod can ONLY find vanilla seeds with vanilla structures and biomes; at this time, the mod cannot find structures and biomes from other mods, and it is not recommended to use WyWF with mods that alter vanilla generation.
