Genflower
by Ampflower
Genflower is a small library for worldgen loot and structure processors, used by datapack authors who build structures on Fabric, Forge, NeoForge and Quilt.
What it does
A block map lets one entry cover several blocks, reducing verbosity in structure processor definitions. Each block in the list can carry a likelihood scale from 0 to 1, which defaults to 1, so a replacement happens only some of the time.
The loot function applies a loot table to blocks whose inventories do not accept the LootTable NBT tag, filling them during world generation. A potion randomiser function picks potions for brewing stands and chests. Weights on list entries are optional and default to 1, using object-in-list notation, and a potion weight map can be written in two ways. The mod is aimed at server-side worldgen and is published for 1.20 and 1.20.1.
Genflower is open source under the Apache License 2.0. Its files target 1.20.1 on all four loaders, with the latest file dated 2024-01-17, and the environment is server-side only, so players do not need it installed.
