How Minecraft Generates Structures

Minecraft uses a deterministic seeded random-number generator to decide where structures spawn. Each structure type has a region grid — for example, villages occupy 34×34-chunk regions. Within each region the game rolls a random position and then checks that the biome is valid. Because the algorithm is deterministic, knowing the seed is enough to predict every structure location.

Java vs Bedrock Structure Generation

Java Edition uses the Cubiomes C library's internal RNG, while Bedrock Edition relies on an MT19937 (Mersenne Twister) port from the MCBEStructureFinder C++ source. CraftMod Hub implements both engines in your browser via WebAssembly, so you get accurate results for either edition without any download.

Strict Biome Filtering

CraftMod Hub always uses strict biome filtering to ensure accuracy — each candidate position is verified against valid biomes for that structure type. This eliminates false positives that can appear with region-grid-only tools.
