One AntiCheat

# One AntiCheat An anti-cheat plugin for Minecraft servers running **1.8 through 26.2** (Paper, Purpur, Spigot). It watches movement, combat, and block interaction, then flags weird stuff for staff. Machine learning is used to help separate real cheating from laggy / weird-but-legit play. By default it alerts and soft-locks. It does **not** auto-ban people. --- ## What it checks **Movement**: speed, fly, Jesus, step, phase, nofall, timer, elytra abuse **Combat**: reach, aura-style patterns, crits, click/aim oddities, hitbox **World**: fast break/place, nuker, scaffold, inventory move **PvP exploits**: crystal / anchor / bed style stuff **Newer game features**: spear, lunge, and mount checks for 26.2 Java and Bedrock (via Geyser/Floodgate) get different thresholds so Bedrock players aren’t treated the same as Java. --- ## How punishment works Defaults are intentionally cautious: - Balanced mode on - Hyper / instant-block off - Auto-kick and auto-ban **off** - High ping or low TPS can pause harsh actions - New joins get a short grace period - Same check usually needs to trip more than once before a soft lock You can turn kicks/bans on later in `config.yml` if you want. Most people should leave them off until they’ve watched alerts on their own server for a bit. --- ## Staff tools Includes the usual moderation kit: ban, mute, kick, warn, freeze, vanish, staff mode, notes, invsee, locate, quick-mod GUI, admin dashboard, and optional Discord webhook alerts. PlaceholderAPI is optional. If you use it, grab **2.12.3+** on 26.2 servers (older builds break on that version string). --- ## Install 1. Put the jar in `/plugins` 2. (Optional) install PlaceholderAPI 2.12.3+ 3. Boot once so configs generate 4. Tweak `config.yml` if you need to 5. Restart Main command: `/anticheat` GUI: `/anticheat gui` or `/anticheat hub` Permissions are listed in `plugin.yml` under `antisystem.*` / `anticheat.*`. --- ## Config starting point ```yaml detection: balanced-mode: true hyper-mode: false instant-block: false smart-anti-false-positive: true punishments: auto-kick: false auto-ban: false ml: enabled: true ``` --- ## Notes - This is a detection / moderation helper, not a substitute for staff judgment. - Works on experimental Purpur 26.2 (including `26.2.build.*` API versions). - If you get a false flag, note the check name, the player’s ping, TPS, and what they were doing (sprint, elytra, vehicle, etc.).
