📷 FrozenAntiCam

Hides underground blocks and entities from a player's client via packet manipulation once they're at or above a configured surface Y level so FreeCam-style mods that let players fly around outside their body see nothing but void where your bases, vaults, and farms actually are. Download it if you want real protection against FreeCam base-finding, not just a detection alert after the damage is done.

🎯 Uses

• 🕳️ Replaces every block at or below a configurable "void Y" with air (or another block) in the packets sent to a protected player, so nothing real is visible underground.
• 📈 Smart activation zone: protection is always on above your surface level, always off far underground, and in the zone between the two it arms based on look-direction and open-sky raycasts — so legitimate digging/mining near bases isn't disrupted.
• 🥧 Optional "pie chart protection" strips tile entities and entity spawn packets so the F3 debug pie chart can't be used to locate chests or mob farms through the void.
• 👻 Hides non-player entities (mob farms, storage mobs, etc.) inside the hidden zone, not just blocks.
• ⚡ Instant protection on zone entry — force-refreshes a radius of chunks the moment a player crosses into the surface zone, so there's no momentary glimpse of real terrain.
• 🌍 Per-world protection list, with optional per-world void-Y overrides.
• 🕹️ Freeze-detection helper logs a console warning if a protected player stops moving for a set time, a common sign of position-spoofing FreeCam abuse.
• 📱 Bedrock Edition (GeyserMC/Floodgate) player support.
• 🎚️ Tunable performance settings — max chunk refreshes per tick, instant-protection radius, and an optional limited-refresh-area mode for lower-powered servers.
