CobbleTracker (Cobblemon)

When a rare spawn appears near a player, CobbleTracker tracks it and places a light column over the Pokémon, which stays visible in the world even at a distance. Tracked spawns persist through a reconnect or relog, so a player who leaves and returns finds the marker still in place, and it is removed once the Pokémon is gone. Each spawn can also be shown on the minimap as a waypoint, and a browsable history keeps a record of everything that has appeared.

The mod reads the spawn pool Cobblemon uses at runtime rather than a fixed list, so it reports real data whatever datapack is installed. Its legendary table lives in legendaries.yml and uses the same vocabulary as Cobblemon's own spawn files. A configurable chance per attempt, a cooldown, and a countdown to the next attempt let server owners tune how often rare spawns show up. Plain chat works without the client mod, and announcements can carry a clickable Create Waypoint link. Per-category announcements can be rewritten, which limits announcements to the categories a server wants.

CobbleTracker is a companion that requires Cobblemon on Fabric or NeoForge. It runs on Minecraft 1.21.1 and Java 21. Files are published for Fabric and NeoForge across 11 release versions, 1.21.1 – 1.21.11, under the MIT License, and the mod is not open source.
