Description
Adds a fully furnished, auto-built Obsidian Bunker structure — a secured shell with entry/security areas, control room, beds, storage, workshop, kitchen, library/enchanting area, farm space, armory, lighting, and internal pathways. Players craft an Obsidian Bunker Control Panel and use its in-game menu to place the bunker at their current position, save that anchor, trigger automated repairs to restore damaged or missing blocks, or initiate a security lockdown that clears nearby hostile mobs and grants temporary resistance to players near the bunker; an action-bar status display shows live bunker status. All bunker anchors, repair and security sweep counts, and last-action status are persisted across world reloads so your bunker and its history survive sessions.

Obsidian Repair Bunker
Quickstart
- Gather obsidian, glass, redstone, a comparator, and an iron door.
- Craft the Obsidian Bunker Control Panel at a crafting table:


- Hold the Control Panel and use it (right-click / tap) to open the menu.
- Choose Build Bunker Here — the fully furnished bunker instantly assembles around your current position.
- Walk inside and explore. Whenever you need to repair or protect the bunker, use the Control Panel again.
Overview
Obsidian Repair Bunker adds a single, powerful item — the Obsidian Bunker Control Panel — that auto-constructs a massive, multi-room obsidian fortress right where you stand. The bunker survives world reloads, can repair itself on demand, and has a built-in security system that sweeps out hostile mobs and shields nearby players.

How To Use
Hold the Obsidian Bunker Control Panel and use it to open an in-game menu with four options:
| Menu Option | What It Does |
|---|---|
| Build Bunker Here | Places the bunker centered on your current position and saves that spot as the anchor |
| Repair Bunker | Rebuilds all damaged or missing blocks at the saved anchor location |
| Security Lockdown | Removes all nearby hostile mobs within the security radius and grants Resistance IV (30 s) to every player near the bunker |
| Bunker Status | Prints a detailed status message to chat showing the anchor coordinates, repair cycle count, security sweep count, and last action |
Action-Bar Display
While you are near the bunker, your action bar continuously shows a live readout:
Obsidian Bunker | Repairs
#| Sweeps#| Hostiles#
This updates automatically so you always know the current threat level.
Abilities And Mechanics
Anchor System
When you first build the bunker, its exact coordinates are saved as an anchor. All future repairs and security sweeps target that same fixed location, even after reloading the world.
Automated Repair
Choosing Repair Bunker re-runs the full structure placement at the saved anchor. Every block — including interior furnishings — is restored to its original state. The repair count increments with each use and is saved permanently.
Security Lockdown
The security sweep scans a large radius around the bunker anchor and instantly removes all hostile mobs found there. Simultaneously, every player within that same radius receives Resistance IV for 30 seconds. The sweep count is tracked and persisted across sessions.
Persistent State
Anchor position, dimension, total repair cycles, total security sweeps, and the description of the last action are all saved to the world and survive game restarts. You never need to rebuild from scratch unless you deliberately choose to place the bunker at a new location.
Progression And Strategy
- First session: Build the bunker somewhere flat with room to expand above and around it — the structure extends roughly 48 blocks in each horizontal direction from your position and about 64 blocks vertically.
- After a raid or cave exploration: Run Security Lockdown before logging off to clear any hostiles that wandered near the bunker, and bank the resistance buff for your return.
- If you mine or blast nearby: Use Repair Bunker to instantly restore the shell without hunting for individual broken blocks.
- Keep one Control Panel safe: The panel stacks to only 1 and is your sole way to interact with the bunker. Store a spare in the bunker's storage room.
- Check the action bar: If the Hostiles counter ticks up while you're inside, trigger a Security Lockdown immediately to clear threats before they breach the entry.
