elo mod

This mod is a server-side Fabric competitive ELO system for Minecraft servers. It gives every player a persistent rating that starts at 1000 and updates automatically when players kill each other. The rating gain is tiered: from 1000 to 1999 players gain +10 ELO per kill, from 2000 to 3999 they gain +1, and above 4000 they gain +0.1. Every death always removes 10 ELO. The mod also tracks kills, deaths, K/D ratio, highest reached ELO, ranking position, and an active league/rank label.

All player data is stored persistently on the server, so ratings survive disconnects and server restarts. The mod supports direct and indirect PvP attribution, including cases like pushing another player to their death, projectile kills, and other player-caused deaths when Minecraft exposes the attacker chain. It includes /elo for personal stats, /elo top [page] for paginated in-game rankings, /elo gui for a Minecraft inventory-based leaderboard UI, and /elo page or /elo export to generate leaderboard.html and leaderboard.json files on the server.

The in-game GUI leaderboard includes:

top 3 podium layout rank colors pagination player head icons highlighted self-position export button for HTML/JSON output The generated HTML leaderboard is designed as a modern styled leaderboard page and includes:

player name current ELO rank position total kills total deaths K/D ratio peak ELO active rank/league player skin/head visuals Important technical note: this is still a Fabric mod, but it behaves like a plugin-style server feature because it is fully server-side. Players do not need to install it on the client just to use the ELO system and commands. NOT: HTML/JSON output is currently not working properly.
