Cobblemon Chat Alerts

When a rare wild Pokémon spawns, is captured or defeated, reaches level 100, becomes ready to evolve, evolves, or adds a new Pokédex entry, a chat message appears. Each alert category can be switched on or off on its own, and so can each rarity filter, covering shiny and legendary finds, Ultra Beast and perfect IV results. The rare-spawn audience can be set to a block radius, a chunk radius or the whole dimension, and coordinates, biome, level and IV details can be added to the message.

The server decides which events trigger an alert, and the client supplies the translated chat text. The mod is a Fabric companion for Cobblemon and requires Cobblemon, Cloth Config API and Fabric API. Mod Menu is optional and offers an in-game configuration screen; without it, the configuration file is edited by hand. In singleplayer, the integrated server reads the same settings, while a dedicated server keeps its own settings file, which takes priority, so a manual change there needs a restart. Files are published for 1.21.1 only, and the environment is client and server, so both sides run it. The code is released under the MIT License and is open source.
