Caves collapse. You get out or die trying.
A mod that makes mining dangerous. Get unlucky breaking blocks and watch the ceiling come down.
⛏️ So what does it do? 🤔
You either hop in a cave or strip mine, coming out with 55 diamonds within one hour and maybe, if you're lucky, the most you did was fight one zombie. Boring. This mod changes that. Start breaking certain blocks and the rock above starts falling. Not all at once, it's progressive. Stone falls, then ore, then dirt, each one triggering more collapses until the whole area settles. The ground shakes under your feet while it happens, and you hear the sound of boulders crashing down. Get out of the way or you're dead. Or at least hurt enough to where that one zombie you'll encounter is actually an issue.
It's not random, there's real block logic behind it. Certain blocks are flagged as being able to trigger a collapse and if you mine one of those blocks, it's just a game of probability. You won't get spam collapses because there's a cooldown too. When you roll the dice and get the bad outcome, blocks directly depending on the block you last mined will fall first... then those blocks land, triggering more blocks to fall. The point is walls collapse realistically, not just everything at once.
Singleplayer or server-side, it just works and needs zero setup.
💔 How Collapses Work 🪨
Break a cave-supporting block and the ceiling takes it personally.
- Stone, Deepslate, Ore, and Dirt blocks can trigger collapses when mined.
- Gravity-affected blocks (sand, gravel, concrete powder) fall and pile up.
- Each falling block has a chance to trigger more blocks around it to collapse.
- The collapse spreads outward in waves. Fast at first, then slower as the chain reaction settles.
- Screen shake and sound effects kick in the moment it starts, so you know something's going wrong.
Blocks you placed yourself don't trigger anything. Collapse logic only cares about natural world blocks. So your pillars stay put.
🕹️ Commands 📢
/triggercollapse [radius]forces a cave-in at your location, useful for testing or just causing chaos. Radius is optional, defaults to 5 blocks./cavecooldown [ticks]sets how long before another collapse can start after one finishes. Keeps the world from being a constant earthquake.
Both commands are restricted to operator permission level (like Minecraft commands typically are), so only server ops can mess with them.
🎬 Screen Shake and Sound 🔊
When a collapse starts, your camera shakes for the duration. The closer you are to the collapse, the more intense it gets. Step too close and the screen's bouncing around. Back away and it calms down.
The mod plays cave rumbling and crashing sounds as blocks fall. Different pitch based on how big the collapse is. It's satisfying in a stressful kind of way.
⚙️ Config, Simple and Optional 🔧
Everything is configurable. Collapse frequency, screen shake intensity, sound volume, cooldown time between collapses. You can dial it all the way down to "basically disabled" or crank it up to pure chaos.
You don't have to touch any of it though. Defaults are already tuned to feel dangerous but not annoying. Open CollapsingCaves.toml in your config folder and tweak whatever you want.
