Moog's Structure Lib (moogs_structures)
by FinnDog_123
Moog's Structure Lib is a library that other structure mods on Fabric, Forge and NeoForge build on, providing data-driven structure types and placement systems.
What it does
Rather than adding structures of its own to a world, the library supplies the generation systems that other mods call. Mods that depend on it can define structures through data files and use its structure types and placement rules. A complete barn structure ships with the mod as a worked example of those features. The library is required by 11 other mods, including MES - Moog's End Structures, MVS - Moog's Voyager Structures and MMV - Moog's Missing Villages. It runs on the server alone, so players join without installing it. Files exist for 1.20 – 26.3 across Fabric, Forge and NeoForge, and the code is under the GNU Lesser General Public License v3.0 only, making it open source.
Key features
