Python script that tweaks the spawnrate of modded minecraft structures. The script does that for all mods in a folder. The mods have to use the datapack system to place structures.
The script works by extracting all data/worldgen/structure_set folders from all mod jars in the modsfolder. Then for every json it looks for the separation and spacing parameter. It applies a modifier to that parameter. It also does some checks on the new parameter in accordance with the minecraft wiki. It then saves the json files in a datapack.
Drop that datapack in your world folder to enjoy the tweaked spawnrates of modded minecraft structures.
Improvements I can think of are: Make clearer to the user what the inputs are. Add logging. Add parameter for datapack version. Add datapack version based on mc version.
Optimizations I can think of are: Don't extract everything. Only what's needed.
