Physics-based anti-cheat for Spigot/Paper 1.20+
Java and Bedrock (Geyser)
>> Requires PacketEvents <<
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
