Jester AntiCheat

0.0.4-beta

A large stability, accuracy and configurability pass on top of 0.0.3 — mostly killing false positives, hardening detections, and exposing every setting. Two new checks added.

✨ New

• GhostBlock check — flags placing a block against a position that is air server-side (the ghost-block region exploit).
• GhostItem check — flags using an item the server doesn't see in the player's hand (inventory desync / fake item).
• Global high-ping guard — above a configurable ping, movement/combat checks alert but don't kick; packet-integrity checks (BadPackets/Crash/Exploit) still enforce. Judged on live ping, so a lag-switch can't buy kick-immunity.
• AFK via WorldGuard flag — mark no-AFK zones natively: /rg flag <region> jester-afk-blocked allow (region list removed).

🐛 False-positive & bug fixes

• Throwing egg / snowball / ender pearl / splash & lingering potion / xp bottle / fishing rod no longer leaves a stuck "using item" state that false-flagged NoSlow & Multitask.
• Criticals no longer false-flags players attacking while riding a horse/boat.
• NoSlow loosened + much faster violation decay — stops false kicks on high-ping players.
• ReachB hardened: pose-aware eye height (swimming/elytra were ~1 block off), riders skipped, absurd high-ping distances ignored, shield/knockback grace, evidence not wiped by skipped hits.
• KillAuraC now needs a streak of attacks-while-GUI-open (fixes a container open/close race).
• TriggerBot now uses real ray-box hitbox intersection instead of a fixed sphere — correct for every mob size (cow/horse/etc.).
• Phase no longer false-kicks when standing on a shulker box as it opens (still catches real phasing).
• AutoParkour division-by-zero / bitmask-overflow guard on window-size.
• Rebalanced the FP-prone rate checks (AutoClicker, FastBreak, FastPlace, AutoArmor, Multitask) so butterfly/drag clicking, fast bridging and quick armor swaps don't trip them.

⚙️ Configuration & tuning

• Every check is now visible & configurable in config.yml — added blocks for ~100 previously-hidden checks.
• ~60 orphaned settings exposed that the code read but the config never listed: violation history/database (SQLite/MySQL), ghost-block/exploit options, Knockback & Reach tuning, ChestStealer/AutoBlock/AutoPot/Explosion, and an Advanced section (high-ping API limits, packet-spam threshold, item-usage resets, etc.).
• 11 command-response messages (freeze / tp / cps / kb / setback / rotate / stats / clearviolations) added to messages.yml so they're customizable.
• Packet-integrity checks (BadPackets / Crash / Exploit) now enforce (kick) with commands.
• AFK settings merged into config.yml under afk: (separate afk.yml removed).
• Reach max-violations set to 3; KillAuraB min-targets, KillAuraC/GhostBlock/GhostItem min-consecutive, and Reach extra-reach are now configurable.

📌 Notes

• Back up your config and let it regenerate after updating — many keys were added/renamed.
• Requires PacketEvents.
