I have zero issue with this mod being in modpacks and I don't need to be credited.

Version 1.7 Notes:
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.

Version 1.6 Notes:
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.
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.
These blocks can start a cave-in when you break them:

Each applicable block that you break has a 1 in 512 chance to start a cave-in.
These rules also apply:

Some blocks do not hide the sky from you.
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 | 48 blocks |
The screen shake and the rumble sound go to 10 blocks past the distance to the side in the table. They are at full strength at the centre, and they decrease to nothing at that limit. After the warning, one group of blocks falls each second, approximately. A group is a set of blocks that touch each other. The mod can also divide the group into more than one shape.
The mod is careful about the blocks that it selects. A block falls only if all of these conditions are true:
The third condition keeps the surface of the world safe. The blocks at the top of a cave fall, but the blocks that hold up the ground stay in position. A block keeps its type when it falls. Stone stays stone and ore stays ore. The blocks fall at two fifths of the usual speed, thus you have time to move away.
Gentle is a new enchantment for pickaxes and other mining tools. Modded tools also accept it.

Use Gentle when you must mine in a large cave and you do not want the risk.
A falling block causes 2 points of damage for each block of the fall distance. The limit is 6 points, which is 3 hearts.

One block does not kill you. If the blocks cover you, suffocation causes more damage.
The movement of the screen can make some players ill.
Set MotionSicknessMode to true at the top of the settings file to remove the screen shake and effects.

With this mode on, the screen does not shake. The mod shows a message across the middle of your screen instead. The message is Cave-In Triggered! when a cave-in starts, and Cave-In Over! when it ends. Each message stays for 3 seconds. This setting is for your game only. It does not change the game for the other players on a server.
The mod writes a settings file with the name collapsingcaves.conf in the config folder. There are 27 settings in the file. Each setting has a short description and its permitted values.
You can change these values and more:
The default values are balanced. The mod does not become an annoyance with them.
An operator can use these commands.
| Command | What it does |
|---|---|
/triggercollapse <size> <player> |
The next applicable block that the player breaks starts a cave-in of this size. The command also removes the cooldown of the player. If a block break does not meet the rules, the mod tells you which rules stop it. |
/cancollapsecheck |
Shows if your position and your current conditions permit a cave-in. The command also examines the block that you look at. If a rule stops you, the command gives the rule. |
/collapsecooldown <player> |
Shows if a cooldown prevents a cave-in for this player. |
/setcooldown <seconds> [player] |
Sets your cooldown, or the cooldown of the player that you give. A value of 0 removes it. |

Cave-Ins by Lettooce was the inspiration for this mod. It is an excellent datapack and everyone must try it. This mod uses a different approach, but that datapack gave me and my friends some of our best memories in Minecraft. Without it, this mod would not exist.
