What the Anti-Cheat is: a simulation anticheat built exclusively for 1.8.8 — 145 named checks, PacketEvents 2.0, 13 languages, persistent violations and per-check exemptions.
The Anti-Cheat is a simulation anticheat built exclusively for Minecraft 1.8.8: its loader refuses to enable on any other server version, because the entire detection model is calibrated for 1.8.8 physics and its packet stream. Packet-level analysis runs on PacketEvents 2.0, shaded into the jar — no ProtocolLib, nothing extra to install. The registry holds 145 named checks across movement, combat, aim, world interaction, protocol and exploit families, every one active out of the box and individually toggleable. One payment of EUR 30.00 includes permanent licensing, per-server binding, and configuration guidance from the developer.
| Check family | What it covers |
|---|---|
| Movement & simulation | The prediction engine (Simulation/OffsetHandler), GroundSpoof, Phase, AntiKB, AntiExplosion, Flight, NoFall ×2, five Timer checks, NoSlow ×2, Step, Jesus, Blink, NoJumpDelay, sprint-state checks and a full vehicle family |
| Combat | Reach and Hitboxes against lag-compensated hitboxes, KillAura A–D, Criticals, NoSwing, two statistical AutoClicker checks, FastBow, BowAimbot, LineOfSight ray tracing, AutoSoup and AutoSplashPot reflex analysis |
| Aim | Constant-rate rotation deltas (AimA), sensitivity-lattice analysis (AimB), smooth-aim coefficient analysis (AimC), duplicate-rotation and modulo-360 protocol impossibilities |
| Breaking & placing | Twelve breaking checks and thirteen placing checks, including the through-wall GhostHand / GhostInteract / GhostPlace ray-traces, ScaffoldTower and the SnapHold camera signature |
| Protocol | BadPackets A–Z (26 checks), PacketOrder A–P (16), Crash A–J (10) and the Exploit family (anvil, book, sign) |
| Interaction | InventoryMove and InventoryWalk, ContainerClickA cadence, FastEquip, FastEat, and packet-order-vs-tick Post checks |
Violation history is a first-class feature, not a console afterthought. On quit, a player's violations snapshot to violations/<uuid>.json and are restored on join with linear decay over each group's decay window — so a relog cannot launder a cheat session. Optional datastore backends (memory by default; redis, mysql/mariadb, postgres, sqlite and mongo opt-in via database.routing) carry sessions and violation history for multi-server setups. On the other side of the fairness ledger, per-check exemption permissions (anticheat.exempt.<check>, plus nosetback and nomodifypacket variants) are re-evaluated every 40 ticks and heal without a reconnect — a rank change applies live.
Punishments are configured per locale in punishments/<locale>.yml as check groups — Simulation, Movement, Knockback, Post, BadPackets, Reach, Hitboxes, Misc, Combat, Autoclicker — each running commands at threshold:interval boundaries. The special actions [alert] and [log] feed staff alerts and the datastore; only the Movement group ships a kick by default, and a test-mode dry-run lets you log what *would* happen before enabling anything. On top of the groups, the auto-kick layer disconnects a player at 100 total violations spread across at least 2 check families — one noisy check alone can never reach it.
The build ships 39 localization resources: config, messages and punishments files for German, English, Spanish, French, Italian, Japanese, Dutch, Polish, Portuguese, Romanian, Russian, Turkish and Chinese. The locale is chosen from the server's language, and international staff and players see alerts, kick screens and punishment text in their language. Alerts carry the check name and description on hover, with an asterisk marking the build's single experimental check (NegativeTimer) so nothing is hidden.
Staff tooling is deliberate: chat alerts with hover details, verbose mode exposing per-check offsets, prediction-level debug on a target player, and client-brand tracking for every join. Integration surfaces include a PlaceholderAPI expansion (%anticheat_player_ping%, %anticheat_player_tps% and friends) and a public plugin API with cancellable events — a flag, a setback or a punishment command can all be intercepted by your own plugins before they run.
Warning:Stated limits, so nobody buys on a wrong premise: this build has no Discord or Telegram webhook delivery (the pipeline was removed; any [webhook] punishment entries are inert), no staff GUI, and no proxy or Folia support — it belongs on the backend 1.8.8 game server. The server host needs Java 17 or newer.
