Structure Generation Overview

To generate a structure in Minecraft, you need four main components:

1. Structure JSON (data/<namespace>/worldgen/structure/) - Defines the structure type and properties
2. Template Pool JSON (data/<namespace>/worldgen/template_pool/) - Defines which structure pieces to use
3. Structure Set JSON (data/<namespace>/worldgen/structure_set/) - Defines where and how often structures spawn
4. NBT Structure Files (data/<namespace>/structure/) - The actual structure data files

Examples Used

Throughout this wiki, we use examples from MoogsVoyagerStructures (MVS).
