findCodexRegionForBoxel(id64): BoxelCodexRegionLookup

Defined in: src/astro/codex-region-lookup.ts:246

Find the galactic region of a system's boxel, from its system address (id64).

This is the region written to the player journal and shown on the codex main page for the system. It is resolved from the 0/0/0 corner of the system's boxel, which can differ from findCodexRegionAt of the system's exact coordinates near a region border.

SystemAddressInput

The 64-bit system address, as a bigint, a normally parsed journal number, or a decimal string (see SystemAddressInput).

BoxelCodexRegionLookup

The boxel corner coordinates — galactic light-years, Sol at origin — and the region there. Those coordinates are also the closest this library gets to a position for an id64 alone: the corner of the system's boxel, so they are accurate to one boxel edge (boxelEdgeLy of the size class: 10 ly for mass code a, 1280 ly for h).

If id64 is not a usable address representation.

If the address is outside 64 bits.

import { findCodexRegionForBoxel } from '@elite-dangerous-almanac/core/astro/codex-region-lookup';

findCodexRegionForBoxel(5306097239922n).region?.name; // -> the codex region

// Approximate position from an id64 alone (boxel corner, in light-years):
const { x, y, z } = findCodexRegionForBoxel(3309179996515n);
({ x, y, z }); // -> { x: 735, y: -185, z: -105 }
