A simple, honest fuel-powered chunk loader for Fabric. No new blocks, no new items — just an Observer, a Trapped Chest, and any fuel you'd use in a furnace.
🔥 How It Works
- Place an Observer block.
- Place a Trapped Chest directly on top of it.
- Put any furnace fuel in the chest (coal, charcoal, coal block, lava bucket, wood, etc.).
As long as there's fuel in the chest, the chunk containing the Observer stays force-loaded — even with no players nearby.
Each fuel item burns for its standard furnace smelting time:
| Fuel | Duration |
|---|---|
| 1 Coal / Charcoal | 80 seconds |
| 1 Block of Coal | ~13 minutes 20 seconds |
| 1 Lava Bucket | ~16 minutes 40 seconds |
| 1 Stick | 5 seconds |
| 1 Oak Plank | 15 seconds |
| 1 Blaze Rod | 2 minutes 40 seconds |
| 1 Dried Kelp Block | 4 minutes |
Once the fuel runs out, the chunk is automatically removed from force-load. No commands needed.
✨ Features
- 🪵 Zero new content — uses only vanilla Observer, Trapped Chest, and furnace fuels.
- 🔢 Multiple loaders per chunk — if a chunk has several Observer+Trapped Chest pairs, it stays loaded as long as at least one is still active. Breaking one won't unload the chunk if others are still running.
- 🔥 Furnace fuel system — any item that burns in a furnace works here. Fuel durations match vanilla furnace smelting times exactly.
