Genflower
World gen & loot utils library for datapacks and mods.
About this Mod
A small worldgen and loot utility library for mods and datapacks
What does it add?
Genflower adds two new structure processors and a loot function to help speed up the development of datapacks,
allowing one to do things that weren't possible, were difficult or tedious before with vanilla's processors.
Loot Functions
Set Random Potion genflower:set_random_potion
A potion randomiser function for potions found in brewing stands and chests.
potions: A potion->weight map expressed in one of two ways:- Map of ID to Weight:
{"minecraft:luck": 1} - Object-in-List:
[{"data":"minecraft:luck","weight":1}]
- Map of ID to Weight:
The weight field is optional and defaults to 1 when using the object-in-list notation.

Structure Processors
Block Map genflower:block_map
A block to blocks mapping to reduce the verbosity of structure processors.
block_map: A block to list of blocks map used for replacing blocks.probability: The likelihood of a block being replaced with a new one.- Scale of 0-1, defaults to 1.

Genflower server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 4 GB RAM is allocated and the loader matches the mod version (1.20.1). You can switch loaders with one click in the panel.
Is Genflower compatible with fabric and forge and neoforge and quilt?
Genflower officially supports fabric, forge, neoforge, quilt for Minecraft 1.20.1, 1.20. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Genflower – how to optimize performance?
Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if Genflower consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
