About this Mod

1.2.0+ REQUIRES DATAPACK

Important note on updating

(This only concers you if you're updating from previous versions to 1.2.0)
Due to major changes in how permission is registered through Flan, datapack is now required. Make sure you have the datapack in place when booting the mod.

Claims should remain intact, however, the permission setting for display case and pokemon spawn cannot be migrated currently, thus you'll need to re-enable them in your claims.

Description

Flan extension that supports Pokemon spawn prevention for Cobblemon.

Simply claim an area, open /flan menu, head over to the last page and a Pokeball with the name POKEMONSPAWN will allow you to cancel PokemonEntity spawning.

Also supports disabling new Cobblemon Display Case interactions.

1.2.0 Onwards requires datapack as well as the mod itself.
