netherhub-map-generator

A Scarpet script to create a Nether hub which represents the Overworld at a 1:8 scale.

For each block in the Nether map, the script scans the corresponding section of the Overworld to determine the average elevation and average block.

Installation

1. Install the Carpet mod for Minecraft.

   This script was written for the following versions, but should work in others.

   • fabric-carpet-1.20-1.4.112+v230608
   • Minecraft 1.20.1

2. Install the script into your world save folder, under /scripts.

3. In game, enter the following command:

   /script load netherhub

Usage

There are two commands.

/netherhub switch

This will switch the player's position between the Overworld and Nether, maintaining relative world position (1:8).

/netherhub generate_map <from> <to> <water_block>

This will generate a map from position <from> to position <to>.

The bottom layer of the map will be a solid platform of <water_block>, which represents sea level.

Example

Existing survival world:

New World:

Exceptions

This script does not map sink holes, or other below sea-level generation. Further, it takes for granted that an elevation at or near 0 would be filled with water.

This script should not be used on an area larger than 256x256 without an appropriate amount of RAM allocated. This is either a quirk of the Carpet mod, or my juvenile implementation.
