Player Stats

Player Stats is a server-side Fabric mod that tracks detailed per-player statistics and stores them in per-player JSON files. It works by polling each player's vanilla statistic map on a configurable interval and recording only what changed since the last poll, which keeps server overhead near zero. The collected data is exposed in game through admin commands with formatted, color-coded output. Nothing needs to be installed on the client; players join with a vanilla client and are tracked automatically.

How it works

On every poll interval the mod snapshots each online player's vanilla stats, computes the difference against the previous snapshot, and adds the deltas to that player's persistent profile.
Profiles are saved to stats/player_data/<player-uuid>.json in the server folder on a configurable save interval, when a player disconnects, and when the server stops.
Tracking starts automatically on server start. No setup is required beyond installing the mod.
Every tracker category can be enabled or disabled individually in config/viper_player_stats.json.

Commands

All commands require operator permission level 2. Tab completion is provided for player names, stat types, and limits.

Command	Description
`/stats list`	Lists all tracked stat categories, grouped by section (Mining and Blocks, Combat, Items, Movement, World and Life).
`/stats <player>`	Shows a full stat card for a player, grouped into sections. Only sections that contain data are displayed.
`/stats <player> all`	Same as above; shows every recorded stat for the player.
`/stats <player> <stat_type>`	Shows one stat in detail: a highlighted total plus a top-entries breakdown (for example the most mined blocks or most killed mobs), with a clickable shortcut to the leaderboard.
`/stats <player> <stat_type> <timeframe>`	Same detailed view; accepts a timeframe argument (`24h`, `7d`, `30d`, `all`).
`/stats top <stat_type> <limit>`	Ranked leaderboard for a stat across all tracked players (limit 1-100). The top 3 ranks are highlighted. Clicking a row opens that player's detail view for the stat.
`/stats reset <player> <stat_type>`	Resets one stat category for a player, or use `all` to wipe the whole profile.

Data storage

Player profiles: stats/player_data/<player-uuid>.json (pretty-printed JSON, includes the player name for readability).
Profiles load when a player joins and save on the save interval, on disconnect, and on server stop.
To wipe a player's data, use /stats reset <player> all or delete the player's JSON file while the server is stopped.
