An open source library mod for structure mod developers.
Foam - marker blocks that define blocks which should stay air (air blocks get treated as structure void). They can spread on their own to fill a region.
Simple structures - a built-in structure type and piece type covering a large range of structure use-cases. Everything is data driven so pack authors can modify structures.
Extended jigsaw - jigsaw structure with a fluent builder and pool bootstrap helpers that reduce boilerplate.
Scattered Grid placement - scattered grid-shaped placement with a structure-tag exclusion zone.
Fixtures - a block that gets replaced with whatever it specifies when a structure is generated.
Spawner profiles - data driven spawner settings that resolve at load time so spawners can be adjusted from data packs
