findCodexRegionAt(point): CodexRegion | null

Defined in: src/astro/codex-region-lookup.ts:208

Find the galactic region at a point on the galactic plane.

This is the region the game records a codex discovery against, and the region name shown when jumping into a system.

CodexRegionPoint

Galactic position, in light-years. Only x and z are read — the vertical y is accepted but ignored, because the region map is a flat X/Z projection.

CodexRegion | null

The CodexRegion containing the point, or null if the point lies outside the mapped region grid.

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

findCodexRegionAt({ x: 0, z: 0 })?.name;      // -> 'Inner Orion Spur' (near Sol)
findCodexRegionAt({ x: 0, z: 25900 })?.name;  // -> 'Galactic Centre'

// A full position works as it comes — no need to strip the `y` first:
findCodexRegionAt({ x: 0, y: 0, z: 0 })?.name; // -> 'Inner Orion Spur'
