Cobblemon Arena
by Raguto
Cobblemon Arena is a Cobblemon add-on that runs competitive battle queues on a server, with ranked ladders, quick casual queues and spectating.
What it does
Players queue for battles from any location with an Arena Orb, and the server assigns each match to a remote arena automatically. Ranked matchmaking runs on several live ladders at once, and casual battles use a quick queue with no ranking attached. Seasons roll over, and each match leaves a result screen and an entry in the match history, which records how often each Pokemon was used.
Server owners can set up their own ranked ladders and define the rules for each one. Format, level cap and the restricted toggle are configurable, and the server can apply clauses for species and items, along with bans on specific Pokemon, items and moves. The ladder configuration is kept authoritative on the server, and reward and progression hooks let administrators connect rewards to results. Spectators can watch active matches, and a team preview with lead selection comes before each battle.
Cobblemon Arena requires Architectury API, Cobblemon and Fabric API on Fabric. It is open source under no license name and published for 1.21.1 on Fabric and NeoForge. Every player and the server need a copy of the mod.
Key features
Ranked ladders
Several ranked ladders can run live at the same time, with seasons that roll over to a new period when they end.
Quick queue battles
Casual battles start from a quick queue, separate from the ranked ladders, for players who want a match without a score.
Remote arena assignment
Matches are placed in remote arenas generated by the server, and the Arena Orb lets a player join the queue from anywhere.
Spectating and match history
Spectators can follow active matches, and the match history records results and how often each Pokemon was picked.
Custom ladder rules
Server owners define the format, level cap, clauses and bans for each ladder, with reward hooks for progression.
