Among Demons Map Editor

Standalone local editor for public/api/data/map.json.

Workflow

1. Open tools/map-editor/index.html locally.
2. Click Import and choose public/api/data/map.json.
3. Edit roads, blocked terrain, shrines, teleports, spawn, or demon spots. Select a demon spot to edit its threat, key demon, and team members.
4. Use Display to switch between the game-style preview and the editor schematic.
5. Click Save Draft to store a temporary draft in this browser.
6. Click Export to download the current map as map.json.
7. Replace public/api/data/map.json with the exported file when you are ready.

Save Draft uses browser local storage only. It does not write to the repo and does not call the website API.

The game preview mirrors the /world map styling with procedural terrain, roads, blocked terrain, shrines, portals, spawn, and demon spots. Demon spot portraits load from public/app/images/demons/map when this editor is used inside the website repo; otherwise the editor falls back to rarity-colored markers.
