Chunck Protector
Chunck Protector is a server-side Fabric mod that marks chunks as protected territories and applies per-area flags to them.
What it does
Chunks are picked with an in-game tool, a named protected area is created from them, and its flags are switched on or off through a 54-slot chest menu or through commands. Every flag is checked on the server when a matching event reaches a protected chunk, covering block changes, player-versus-player hits, blasts, thrown projectiles, ender pearl teleports, fluid movement, fire spreading, flight and mob spawns. Where selections overlap, the server consults an internal cache that is rebuilt whenever the configuration loads or reloads.
Chunck Protector requires Fabric Loader and Fabric API on the server, and its environment is server-side only, so connecting clients need nothing extra. The mod is published for Fabric across 17 release versions, and the latest file is 1.0.0+26.3 for 26.3. The code is under the MIT License, and the project is not open source.
Key features
Chunk-based territories
Protected areas are built from whole chunks, so boundaries follow the chunk grid rather than arbitrary coordinates.
Per-area flags
Each area carries its own set of flags, covering block changes, PvP, blasts, projectiles, ender pearls, fluid movement, fire, flight and mob spawns.
Chest menu and commands
Flags can be changed in a 54-slot chest GUI opened from the menu command, or toggled directly with the area toggle command.
Autocompletion and config reload
Identifiers and flag names can be autocompleted in the console, and the JSON configuration is reloaded with one command after manual edits.
