About

Formations is a library mod which adds additional features to datapacks for generating structures!

Features
Structure Types
Formations adds two new structure types: formations:simple and formations:pieced. These essentially correspond to the vanilla regular and jigsaw structure types, but with better placement and a clearer json format.
Both types can choose from the following placements:
| Identifier | Description |
|---|---|
surface | Will place the structure at the top layer of solid blocks |
ceiling | Will place the at the bottom layer of solid blocks |
on_water | Will place the structure at the top layer of blocks if those blocks are water |
on_lava | Will place the structure at the top layer of blocks if those blocks are lava |
underground | Will place the structure somewhere between the top and bottom layers of blocks |
underground_surface | Will place the structure between the top and bottom layers of blocks, at the bottom of an open area |
underground_ceiling | Will place the structure between the top and bottom layers of blocks, at the top of an open area |
underground_buried | Will place the structure between the top and bottom layers of blocks, such that it is not exposed to any open area |
underground_on_lava | Will place the structure between the top and bottom layers of blocks, in an open area on top of lava |
Structure Pool Element Types
Formations adds one new structure pool element type, formations:single_pool_element. The element type allows setting a different ground level rather than vanilla's fixed ground level of 0. The ground level can be set through the ground_level key.
Structure Processors
Formations adds a bunch of new structure processors.
