Portal Calculator

by Fayr

Portal Calculator is a Fabric command for working out Nether portal coordinates, so a position in the Overworld can be matched to its Nether counterpart.

FabricClient and serverCC0 1.0 UniversalOpen source1.20.1 – 26.3

What it does

The mod adds a convert command that takes coordinates and returns the matching location for the other dimension, which saves players from doing the 8-to-1 scaling by hand when linking portals. It is available to players at permission level 0, so no operator rights are needed. The source is released under the CC0 1.0 Universal license, which makes the code open source, and the environment is client and server.

Key features

  1. Convert command

    A convert command calculates the Nether portal coordinates that correspond to a given Overworld position.

  2. No operator rights needed

    The command works at permission level 0, so any player can use it on a server without extra permissions.

  3. Overworld and Nether

    Coordinates can be converted in either direction, between the Overworld and the Nether.
