Counter

Physics-based anti-cheat for Spigot/Paper 1.20+ Java and Bedrock (Geyser) > Requires PacketEvents << I've been working on Counter for months, slowly improving it as time passes. It's the runner-up to my earlier NoChance anti-cheat project. I rebuilt this from the ground up around a full movement prediction engine instead of simple threshold checks. Expect rough edges and report what you find. Features 80+ checks across movement, combat and player behaviour Prediction engine - simulates vanilla physics each tick (friction, gravity, water/lava, ladders, ice, soul sand, levitation, slow falling, depth strider, swift sneak and more) Combat analysis - reach, killaura (legit-aim and multiaura included), aim patterns, autoclicker, velocity/anti-KB, hitbox, backtrack, crits, mace Movement coverage - fly, speed, timer, jesus, phase, step, elytra, boats/vehicles, ground spoof, blink, scaffold-walk Player checks - fastbreak/nuker (full vanilla dig-speed math with enchants and effects), scaffold, tower, xray heuristics, inventory, fast use, crystal/anchor/totem, bots and crash packets Bedrock support - Geyser/Floodgate players get checked too, touch-unfriendly checks skip them automatically Client info - staff see what client and version players join with (Forge, Fabric, Lunar, Badlion, Bedrock and more) plus self-reported mods World Downloader blocking - detects the mod, disables it remotely and flags the player Smart enforcement - safe setbacks with confirmed snapshots, violation ladder, configurable punishments, optional double filtering for FP-sensitive servers Auto-tune - loosen-only tuning engine driven by live stats, plus scheduled violation auto-clear In-game GUI - alerts, per-check toggles, settings and tuning from one menu Discord webhooks , persistent flag storage, lag/TPS/ping compensation throughout Commands /counter (aliases /c, /anticheat) - open the main menu /counter alerts - toggle alerts /counter check <name> - toggle a check /counter info <check> - check details /counter status [player] - server/player info /counter vl <player> - show all violation levels /counter top - top online violators /counter history <player> - stored flag history /counter client <player> - client, version and mods /counter exempt <player> - temporarily exempt a player /counter logs [page] - view recent flag logs /counter debug [player] - toggle debug mode /counter tune [apply] - auto-tune checks from flag data /counter shadow - compare the new prediction model /counter reset <player> - reset player data /counter clear - wipe all violation data /counter reload - reload config Permissions counter.admin - full access (alerts, gui, debug, kick, ban) counter.alerts - receive cheat alerts counter.gui - access the GUI counter.use - use /counter counter.exempt / counter.bypass - exclude a player from checks (default false)
