About this Mod

Cobblemon Random Battles
Bring the thrill of Pokémon Showdown's Random Battles directly into your Cobblemon server!

Cobblemon Random Battles is a server-side minigame mod that lets players instantly jump into competitive, fair, and unpredictable Pokémon battles.

Features

  • True Random Teams: Upon starting a battle, both participants are temporarily given a full team of 6 random Pokémon. These Pokémon are generated using Showdown data.
  • Safe Party Restoration: Your original Pokémon are completely safe! Once the battle concludes, your original team is instantly restored. The mod features robust fail-safes so your team is restored even if you flee, win, lose, or suddenly disconnect mid-battle.
  • PvP Matchmaking: Use the sleek built-in GUI (/randombattle menu) to join a server-wide matchmaking queue and get matched with another random player looking for a fight.
  • Direct Player Challenges: Want to battle a specific friend? Challenge them with /randombattle challenge ! They will receive a beautiful, interactive chat message with clickable [ ACCEPT ] and [ DECLINE ] buttons.
  • Proximity Checks: Prevents cross-map sniping by requiring players to be within 20 blocks of each other to send and accept direct challenges.

Commands

  • /randombattle menu - Opens the main minigame UI to join the matchmaking queue or select a player to challenge.
  • /randombattle challenge - Sends a battle request to a specific player.
  • /randombattle accept - Accepts an incoming battle request.
  • /randombattle decline - Declines an incoming battle request.

Installation

This is a server-side mod. Clients do not need to install it to play! Simply drop the .jar into your server's mods folder. Make sure you also have the base Cobblemon mod installed!

Note: This mod is currently in Alpha. A future update will introduce configuration files allowing server owners to map custom items (like Mega Stones or Z-Crystals from addons) to the random showdown teams!
