<center> !(https://github.com/ccdelic1/collapsingcaves/blob/main/ImageBlocks/collapsingCavesBanner.jpg?raw=true) --- ### This pages mod description only accurately portrays version 1.7+ of the mod. New versions of this mod **(v1.6+)** are for Fabric and NeoForge only. <br> ### You can use this mod in modpacks. I have zero issue with this mod being in modpacks and I don't need to be credited. --- !(https://github.com/ccdelic1/collapsingcaves/blob/main/ImageBlocks/BugsAndBurdensUpdate.png?raw=true) **Version 1.7 Notes:** <br> This update, called the _'Bugs & Burdens Update'_ addressed a large number of cave-in bugs, added QoL configuration options with fine-tuned logic to ensure players can enjoy the mod without being griefed or burdened, added a small buffer before a cave-in begins after it's been triggered, improved sound effect logic (and a few new sounds!) and added extra commands for bug-testing and experimentations. --- !(https://github.com/ccdelic1/collapsingcaves/blob/main/ImageBlocks/annoyanceFixUpdate.png?raw=true) **Version 1.6 Notes:** <br> This update, called the _'Annoyance Fix Update'_ addressed a notable lack of 'power' to prevent cave-ins, issues with environments being griefed and turned ugly, and caved-ins happening inappropriately, incorrectly and far too frequently. --- ### What This Mod Does You mine a block below ground. Sometimes the ceiling above you falls. <img src="https://raw.githubusercontent.com/ccdelic1/collapsingcaves/main/ImageBlocks/NewGifs/ceilingfalls.gif" alt="The Ceiling Falling From A Cave In" width="640" height="180" /> <br> When a cave-in starts, the screen shakes and you hear a deep rumble. The first **3 seconds** are a warning. No block falls in this time. Use the warning to move to a safe position. This time is part of the time of the cave-in. The mod does not add it to the end. <img src="https://raw.githubusercontent.com/ccdelic1/collapsingcaves/main/ImageBlocks/NewGifs/caveinstarts.gif" alt="The Start of a Cave In" width="640" height="180" /> <br> After the warning, groups of blocks fall from the ceiling. The blocks hurt players and mobs, they make dust when they hit the ground, produce a sound effect and stay in the position where they land. <img src="https://raw.githubusercontent.com/ccdelic1/collapsingcaves/main/ImageBlocks/NewGifs/youcanflee.gif" alt="Player running from a Cave In" width="640" height="180" /> <br> A cave-in has a fixed centre at the block that you broke.

If a solid block is above these blocks, the sky is hidden and a cave-in is possible again. * The mod reads the sea level from the world generation. If a mod or a data pack moves the sea level, the height limit moves with it. You can turn off this limit in the settings file. You cannot set the sea level, because the world gives this value. <center> --- ### Cave-In Sizes There are three sizes.

### What This Mod Does You mine a block below ground. Sometimes the ceiling above you falls.

When a cave-in starts, the screen shakes and you hear a deep rumble. The first 3 seconds are a warning. No block falls in this time. Use the warning to move to a safe position. This time is part of the time of the cave-in. The mod does not add it to the end.

After the warning, groups of blocks fall from the ceiling. The blocks hurt players and mobs, they make dust when they hit the ground, produce a sound effect and stay in the position where they land.

A cave-in has a fixed centre at the block that you broke. It does not follow you. If you move away from the centre, you are safe.
### How A Cave-In Starts These blocks can start a cave-in when you break them:
Stone and the different types of stone Deepslate All ore Dirt, clay and the different types of dirt Gravel Sulfur and cinnabar, in the newer versions of the game only

Each applicable block that you break has a 1 in 512 chance to start a cave-in.
### "Cave-In Possible" Conditions These rules also apply:
You cannot start a cave-in if you can see the sky. The block that you break must also not see the sky. You must be at or below the sea level of the world plus 15 blocks. In the Overworld this is Y 78. You cannot start a cave-in for 20 minutes after you log in. You cannot start a new cave-in for 20 minutes after your last one. A tool with the Gentle enchantment never starts a cave-in. No more than 3 cave-ins can occur at the same time.

Some blocks do not hide the sky from you.
Leaves, logs, glass, glass panes, beehives, mangrove roots, snow layers, grass, vines and the other small plants let the sky through. You cannot put leaves above your head and mine in safety. If a solid block is above these blocks, the sky is hidden and a cave-in is possible again. The mod reads the sea level from the world generation. If a mod or a data pack moves the sea level, the height limit moves with it. You can turn off this limit in the settings file. You cannot set the sea level, because the world gives this value.
### Cave-In Sizes There are three sizes. A small cave-in is the most frequent size.
| Size | Chance | Time | Blocks in each group | Distance to the side | Height above you | | --- | --- | --- | --- | --- | --- | | Small | 60% | 60 seconds | 14 to 17 | 16 blocks | 24 blocks | | Medium | 30% | 90 seconds | 18 to 21 | 24 blocks | 32 blocks | | Large | 10% | 120 seconds | 22 to 35 | 32 blocks
