Antixray

🔒 AntiXray Plugin: AntiXray is a lightweight anti-cheat plugin for Minecraft 1.21+ (Paper/Spigot) that prevents X-Ray cheating using ProtocolLib packet manipulation. Features:

🎮 Player Experience: Players mine normally – ores reveal when digging nearby. X-Ray cheaters see only stone/deepslate instead of diamonds, emeralds, and gold. No lag, no false positives, invisible protection.

⚙️ Admin Commands: (/antixray – requires antixray.admin permission): /antixray reload – Reload configuration. /antixray toggle – Enable/disable protection. /antixray mode <1|2> – Switch engine mode (1=stone/deepslate, 2=random blocks).

🛡️ Protection: Hidden ores: Diamond, Emerald, Gold, Iron, Coal, Lapis, Redstone, Copper, Ancient Debris, Nether ores. Engine Mode 1 (Recommended): Replaces ores with stone (Y≥0) or deepslate (Y<0). Engine Mode 2: Replaces ores with random blocks from configurable list. Reveal mechanism: Ores become visible within update-radius (default: 2 blocks) when player starts mining nearby. update-on-damage: true triggers on first hit.

🔐 Security: Packet-level obfuscation using ProtocolLib – modifies chunk data before sending to clients. Each player has individual exposed-block tracking (memory-stored, cleared on logout). Blocks X-Ray texture packs, mods, and shaders effectively. What it blocks: X-Ray resource packs, X-Ray mods (Wurst, Impact), X-Ray shaders, Cavefinder tools. What it doesn't block: ESP, movement hacks, combat hacks (use dedicated anti-cheat for those).

📦 Requirements: Minecraft: 1.21+ Dependencies: ProtocolLib (required) Server: Bukkit/Spigot/Paper 1.21.4+ Java: 21

⚡ Performance: CPU: Low – obfuscation only on chunk load + mining events (event-driven). RAM: Minimal – ~32 bytes per exposed block (1000 blocks ≈ 32KB per player). Network: Negligible – small sendBlockChange() packets only. Thread-safe (ConcurrentHashMap), no continuous scanning, asynchronous chunk processing.

🚀 Installation:

Download and install ProtocolLib from SpigotMC Place ProtocolLib.jar in plugins/ folder Place AntiXray-2.0jar in plugins/ folder Restart server Configure plugins/AntiXray/config.yml (optional)

Plugin auto-detects ProtocolLib on startup (disables if missing).
