FP's AntiFreecam

✨ New: Smart Fill

Smart Fill now reveals caves based on what you can actually see. Once a second, the plugin casts rays from your eyes and reveals every cave section they pass through, out to your render distance (or reveal-max-distance-cap, default 128 blocks). Large caverns are now revealed across their full width instead of ending in a wall of fake stone partway across.

Walls and corners still block the view, so bases behind them stay hidden. The close-range reveal around you still works as before.

Config (protection.smart-fill):

• reveal-line-of-sight: turn the ray sweep on or off (default true)
• reveal-follow-render-distance: limit the sweep to your render distance (default true)
• reveal-max-distance-cap: hard cap in blocks, 32 to 256 (default 128)
• reveal-sight-budget: max blocks checked per player per second (default 60000)

🧩 Compatibility

• Supports Paper, Folia, Purpur and Spigot, 1.19 – 26.3.
• Spigot support fixed: the plugin used to crash on plain Spigot. It now works there, with these differences:
  • Chunk refreshes use the server's view distance instead of each player's.
  • /fpac stats shows TPS as N/A.
  • Freecam mod detection is turned off, because it needs Paper.
• Requires PacketEvents 2.11.0 or newer. Use the PacketEvents version that matches your Minecraft version (for example 2.14.0+ for 26.3).

🐛 Bug fixes

• Sounds, particles and mob/item spawns in hidden areas now follow pie-chart-protection and Smart Fill's reveal, so you can hear and see them in your own cave again.
• Fixed some block sounds being hidden or shown based on the wrong position.
• pie-chart-protection: false now also stops hiding chest/sign/spawner data.
• raycast no longer turns off Smart Fill's look-direction reveal.
• Fixed freeze detection never triggering.
• Fixed entities staying hidden after turning hide-entities off and reloading.
• performance.max-chunks-per-tick is now actually used.
• Smart Fill reveal settings now load on startup instead of only after a reload.

🧹 Config cleanup

• config.yml is reorganized, with shorter and clearer comments.
• Removed the protection.raycast section. It now uses fixed, tuned values.
• Freecam detection's translation keys are now built in.
• Removed the unused folia-optimizations option.
• Removed keys are deleted from existing configs automatically on update; your other settings are kept.

Config version 5.1. For the new clean comments, delete plugins/FPAntiFreeCam/config.yml and let it regenerate.
