Structural Safety

Keep generated structures intact. Automatically. Structural Safety protects naturally generated structures from grief and environmental damage by switching players into Adventure Mode inside them — while still letting them loot, fight, and explore. Fully configurable in‑game, no commands memorized required.

✨ What it does

When a player enters a protected structure (dungeon, mansion, trial chamber, village …):

• 🛡️ They are put into Adventure Mode automatically (with an action‑bar notice + sound). When they leave, their previous game mode is restored — even across disconnects/restarts.
• ⛏️ No griefing: blocks can't be broken or placed freely…
• ✅ …but exploration still works: loot chests, fight mobs, pull levers, brush suspicious sand, and break a curated list of "weak" blocks (cobwebs, vines, pots …) so you never get stuck.
• 💥🔥🌋 Environmental protection: explosions, fire (including fire spread and lava‑lit fire), and flowing lava cannot destroy protected structure blocks.
• 🚪 Anti‑stuck: a /structuralsafety escape command teleports a trapped player to the nearest safe spot.

Everything is configurable live, in‑game, through a clean clickable menu — no file editing needed (but a JSON config exists for power users).

🎮 Core features

Adventure‑Mode protection

Players inside a protected structure are forced into Adventure Mode every second. Creative and Spectator players are never affected. Optional Op‑Bypass lets staff keep their game mode.

Smart interaction whitelist

Even in Adventure Mode, players can still:

• Break a configurable list of breakable blocks by sneak + right‑click (follows vanilla tool rules — e.g. cobweb needs a sword/shears).
• Interact with whitelisted blocks (repeaters, comparators, suspicious sand/gravel — brushable blocks always allowed).
• Place whitelisted items, split into:
  • Temporary items (e.g. torches, ladders, hay/slime for self‑rescue) that auto‑remove after a timer.
  • Permanent items (e.g. ladders, scaffolding, ender eye).

Environmental damage protection (toggleable)

Each can be toggled independently. Turn Fire off and lava/fire behave exactly like vanilla again.

Sprawling structures

Spread‑out structures like villages use their overall bounding box instead of tight per‑building boxes — so plazas, gardens and paths between houses are protected too. The sprawling list is configurable.

/escape anti‑stuck

Teleports the player to the nearest safe surface position (no lava/fire, room to stand). Has a configurable cooldown when used outside a structure (to prevent fast‑travel abuse) but is always allowed when actually stuck inside a protected area.

🧱 Command reference

Player commands work for everyone. Admin commands require permission level 2 (op). Open the clickable menu any time with /structuralsafety.

Player

Admin — overview

Admin — structures

Admin — player allowances

Admin — timers

Structure names accept either the plain name (e.g. Pillager Outpost) or the raw ID (e.g. minecraft:pillager_outpost), with tab‑completion.

🗂️ Default protected structures

Out of the box these vanilla structures are protected: abandoned_mineshaft, simple_dungeon, pillager_outpost, desert_pyramid, jungle_pyramid, mansion, monument, stronghold, trial_chambers, ancient_city, fortress, bastion_remnant, nether_fossil, end_city.

Modded structures are detected automatically and added to the config (disabled by default) — just enable the ones you want via /structuralsafety admin structure protect <name>.

⚙️ Configuration

A JSON config is created at config/structuralsafety_settings.json. Everything there can also be set in‑game, so editing by hand is optional. Keys include: structures, sprawling_structures, weak_blocks, interact_allowed, temp_place_items, perm_place_items, cooldown_minutes, temp_minutes, op_bypass, protect_explosions, protect_fire, protect_lava.

New default entries are merged into existing configs on update without wiping your customizations.
