# Amplified world generation without excessive flooded caves

This datapack changes Minecraft's noise parameters to remove flooded caves in amplified world generation.
It achieves this by increasing the terrain density (= more stone/dirt) around y=46,
which cuts off most surface water from the cave systems.
It shouldn't make it harder to find caves since some seemingly ignore the inital density generation.

## Installation

Download the [.zip](https://github.com/FliegendeWurst/amplified_fixed/releases/download/v1/amplified_fixed.zip) and save it in your datapacks directory.

## Screenshots

| ------------------------- | --------------------- |
| ![vanilla](./vanilla.jpg) | ![fixed](./fixed.jpg) |

Or a three-way comparison:
| Normal | Amplified | Amplified (fixed) |
| ------ | --------- | ----------------- |
| ![normal](./random_vanilla.jpg) | ![amplified](./random_amplified.jpg) | ![fixed](./random_fixed.jpg) |

As you can see, some flooding near the surface remains. I believe that can be corrected by tweaking the y level of my fix, but that will also lead to more terrain changes.

## Removing all flooded caves

It is also possible to remove normal flooded caves by decreasing the `fluid_level_floodedness` noise.
