DaynAC Plugin (1.21.11) – Catch AimBot and KillAura Cheaters in Live PvP Fights

DaynAC Plugin guards Bukkit and Paper servers with a neural-network anticheat system. It spots AimBot and KillAura cheats by watching hit behavior during PvP fights. Server admins record real and cheating combat sessions to train the model directly on their own server. Because it runs in pure Kotlin, the server needs no Python or outside machine-learning libraries.

Features:

• Behavior-Based Detection: Checks aim geometry, rotation entropy, and hit timing predictability instead of click speed.
• Custom Server Training: Ships with no prebuilt signatures and learns strictly from combat data recorded on your server, detecting nothing until you train it.
• Step-by-Step Punishments: Starts with cooldown admin alerts, moves up to reducing or canceling hit damage, and kicks or bans a player only after flagging multiple separate hit windows.
• Runs checks on separate background threads so live retraining and active detection do not freeze the main server tick.
• Saves the dataset, model, and settings locally inside the plugin folder with zero outside telemetry.
• Protects player privacy in saved CSV files by replacing UUIDs with salted SHA-256 hashes.
• Includes an admin GUI for watching players, complete with quick teleport and temporary bypass options.

Commands:

• /daynac eval: Shows model performance stats with confidence intervals, separates data by session to stop data leaks, and warns you if your recorded dataset is too small.
