hxwi1structures

Structures are added by dropping NBT files into the structures folder inside the mods folder, and the mod detects them automatically. Each structure is then given its generation rules through the in-game GUI, where a player picks an NBT file and sets biomes, chance, Y range and minimum distance. The screen offers four placement modes, and biome tags and dimensions can be used to narrow where a structure appears. Running the hxwi1 config command opens the same setup for generation rules, so no JSON has to be written by hand.

The mod is aimed at modpack makers who want to add buildings to a world without writing configuration files. A structure can be dropped into a world by a few clicks, and the hxwi1 spawn command places one at the current position for testing. The hxwi1 biomeinfo command shows which structures generate in the current biome. Hxwi1Structures is marked as high performance, and it works alongside Mixin-based mods, with good compatibility reported. The license is MIT, but the project is not open source.

Client and server: the server and every player need the mod. Files are published for Forge and NeoForge, covering 1.20.1 and 1.21.1, with the latest 0.3.1 build marked alpha.
