StructureBlock
Protect structures! A mod that allows mod, modpack and datapack authors to prevent breaking and placement within structures.
I don't know my version or loader
StructureBlock is a mod that will allow you to ensure structures are protected.
By adding structure ID's to a config file, you can decide wether breaking or placement of blocks within a structure is allowed. You can also utilise a wildcard to block actions in multiple structures at once. I.e. the ID for a plains village is minecraft:village_plains. However if you want to protect all village variants, you can simply block minecraft:village_*.
The Mod only needs to be installed on a Server to work, but you can still install it client-side for singleplayer worlds.
