Formations - Library for Extending Structure Datapack Capabilities

Formations is a library mod that significantly expands the possibilities of structure generation through datapacks in Minecraft.

Main Features

Structure Types

The library adds two new structure types: formations:simple and formations:pieced. These types correspond to standard vanilla structures but offer improved placement and a more understandable JSON format.

Both types support the following placement options:

• surface - placement on the top layer of solid blocks
• ceiling - placement on the bottom layer of solid blocks
• on_water - placement on the top layer of blocks if those blocks are water
• on_lava - placement on the top layer of blocks if those blocks are lava
• underground - underground placement between top and bottom block layers
• underground_surface - underground placement at the bottom of an open area
• underground_ceiling - underground placement at the top of an open area
• underground_buried - completely buried underground placement without access to open areas
• underground_on_lava - underground placement in an open area above lava

Structure Pool Elements

Added a new type of structure pool element - formations:single_pool_element. This element allows setting an arbitrary ground level instead of the standard level 0 in vanilla game through the ground_level parameter.

Structure Processors

Formations includes numerous new structure processors:

• formations:random_bed_color - random bed color changes
• formations:biome_replacements - replacement of certain blocks (wood, bricks, grass) depending on the biome
• formations:fill_brewing_stands - filling brewing stands with random potions and blaze powder with parameters slotFillChance and maxBlazePowder
• formations:fill_chiseled_bookshelves - filling chiseled bookshelves with enchanted books with parameter slotFillChance
• formations:block_age - adding block aging effect with parameters mossiness, degradation, disintegration, replacing regular blocks with mossy or cracked variants
• formations:random_plant_growth - random change of plant growth stage with parameters minGrowth and maxGrowth
