RXVY ANTI CHEAT

📦 RXVY AntiCheat v15.5 Changelog Release Date: February 16, 2026

🔥 Major Features Packet Timer & Balance Engine: Added a strict "Balance" check that tracks packet flow in milliseconds. This detects Blink, Timer, and GameSpeed cheats that manipulate time rather than distance.

Velocity Decay System: Replaced the static "immunity timer" with a dynamic velocity buffer.

Old: Hit player -> 1s immunity (Cheaters could fly).

New: Hit player -> Exact knockback vector applied -> Decays by 0.6x per tick. (Cheaters warp back if they exceed the specific knockback force).

Lag Spike Safety Patch: Added a "Ping Jitter" detector. If a player's ping spikes >350ms, the system grants a temporary 1-second immunity to prevent false bans on laggy players.

🛡️ Security & Exploits Attribute Clamping: The engine now strictly caps GENERIC_MOVEMENT_SPEED at 0.4 server-side.

Fixes: Exploits where cheat clients spoof high attribute values to bypass speed checks.

Climbable Recognition: Added native support for Ladders, Vines, Weeping Vines, and Scaffolding.

Fixes: False positives when climbing walls or using scaffolding.

🌍 Physics & Environment Honey Block Support: Friction engine now accounts for Honey Block stickiness (preventing "Gravity" false flags).

Sweet Berry Bush Support: Speed limit is now dynamically reduced when inside berry bushes to prevent "Speed" false flags.

Soul Sand & Ice: Full friction simulation for Soul Sand (slow) and Blue Ice (fast), allowing legitimate gameplay mechanics without rubberbanding.

Step Detection: Explicitly handles 0.6 (Block) and 0.5 (Slab) step heights to prevent them from triggering "Gravity (Rise)" violations.

🔧 Technical & Build ProtocolLib Integration: Fixed Dependency not found errors by forcing local library usage via systemPath.

Null Safety: Patched NullPointerException errors when checking attributes or potion effects on new players.

Packet cloning: Moved packet processing to the main thread via deepClone() to prevent asynchronous world access crashes.

Status: PRODUCTION READY Recommended Use: Survival Multiplayer (SMP) servers with 1.20+ mechanics.
