About this project
What does Cobblefight add?

Rated Cobblemon battles for Minecraft servers.
CobbleFight gives players a fair way to find competitive battles without interrupting normal server play. Join the queue whenever you are ready, get matched with a player near your Cobble Fight Rating, and battle in a server-made arena. When the match ends, both players return to where they were.
Every player begins at 1,000 CFR. Wins and losses change that rating, ranks mark long-term progress, and the leaderboard shows who is currently on top.
For players
/cobblefight joinjoins matchmaking for any arena available to you./cobblefight join <arena>queues only for a chosen arena./cobblefight leaveleaves the queue./cobblefight leaderboard [page]shows the CFR leaderboard.
You need at least one Pokémon in your party to queue. Changing your party or anything about a Pokémon in it while waiting automatically leaves the queue. Matches begin automatically once both players arrive. Leaving the battle or taking too long to choose a move awards the win to the opponent.
Players who also install CobbleFight on their client can press 0 to open the Player Profile, showing their CFR, rank, record, recent battles, and most-used ranked Pokémon. The same screen can join or leave matchmaking.
For server owners
CobbleFight is designed to fit the server around it. You can create multiple arenas in-game, restrict arenas by rank, adjust matchmaking and rating rules, rename ranks, and choose the rewards given for wins, losses, milestones, and first-time rank promotions.
Rewards can use items, money, or server commands. CFR, rank, wins, losses, matches, and win streaks are also available as placeholders for chat, scoreboards, and permission setups.
Placeholder API is integrated
Arena setup starts with /cobblefight arena wand. Select both arena corners and player spawns, then save it with /cobblefight arena create <id>.
