Structural Safety
by MrStilu2k6
Structural Safety is a server-side protection system that keeps generated structures and world-generation features from being broken or changed by players in Survival.
What it does
On a server running Structural Safety, players stay in Survival Mode, but the server decides which blocks may be broken, placed, or interacted with inside a protected area. When a player enters a protected structure, rules from the configured area apply automatically, and the same rules stop environmental effects from damaging important generated areas. Allowed blocks still follow normal vanilla mining, so speed, tool durability, enchantments and drops behave as usual.
The mod covers Minecraft structures and world-generation features alike. Vanilla Monster Rooms and Dungeon Spawners are detected and protected, and generated areas added by other content receive the same system. Rules can be set through commands or a server-side graphical menu, and everything can be changed live in-game. Structural Safety requires Fabric API and is published for Fabric, Forge and NeoForge across six game versions, 1.20.1 – 26.2.
Key features
Protected structures
Vanilla structures and world-generation features are guarded so players cannot break or alter them.
Vanilla mining on allowed blocks
Blocks that are permitted to break use normal mining speed, tool durability, enchantments and drops.
Configurable interactions
Server owners choose which blocks and items players may interact with or place, and which may be broken.
Live graphical menu
Protection rules can be changed in-game through a server-side menu or by commands, without restarting.
