Frequently asked questions

How do I start using this mod?
The mod activates automatically once installed—no setup needed. Start mining underground normally, and you'll notice ceiling blocks can collapse if you dig them out with air blocks below. Use /function cave_in:config to adjust collapse frequency to your preferred difficulty.
What triggers a cave-in?
Mining a ceiling block when there are two or more air blocks directly beneath it can cause a collapse. Collapses become more frequent and severe below Y=30. Using Silk Touch tools or placing structural pillars nearby prevents collapses entirely.
How do I know if a ceiling block is safe to mine?
Hold a Soul Lantern in your off-hand and a Pickaxe in your main hand—cyan particles mean the block is safe (supported by a pillar), while red particles warn of danger. This lets you plan your mining route before breaking any stone.
How do I build a structural pillar?
Craft a pillar by placing a stripped log between two polished deepslate blocks on a crafting table. Place the pillar vertically underground between 2 and 10 blocks tall, and it will protect all ceiling blocks within a 12-block range from its top.
