Protect Your Structures
by arcanealloy
Protect Your Structures keeps players from breaking or placing blocks inside generated structures, including vanilla and modded ones, by protecting the areas that the configuration file defines.
What it does
Players can destroy and place blocks in structures they explore, which can damage a village, dungeon or other build made by the world generator. This mod limits those actions, so generated structures keep their layout while players move through a world. Protection covers the structures the mod is set up to guard, and the rules are changed by editing the protectyourstructures.json file, which is created with the mod's configuration.
The mod runs on Forge and NeoForge, with builds for 1.19.2 – 1.21.1 published as release versions for 1.19.2, 1.19.3, 1.19.4, 1.20.1 and 1.21.1. Every player and the server need a copy of the mod. The code is not open source, and the mod is released under All rights reserved.

Use cases
Multiplayer servers
A server where many players explore can keep villages and dungeons intact, with the rules set in the configuration file.

Who it’s for: Server owners who want generated structures to stay unchanged, and map makers who depend on the layout of villages and dungeons in their worlds.
