GlymeraWebMap — Your World, Live in the Browser

A live map of your server world that anyone can open in a web browser — like Dynmap, for Hytale. The plugin serves the map itself from your game server: no web hosting, no external services, no accounts. Install the jar, open http://<your-server-ip>:8123, and share the link with your players.

What is GlymeraWebMap?

A persistent, ever-growing map of your server. While players explore in-game, the plugin renders the world from Hytale's own cartography into map tiles and serves them on a built-in web page. Everything mapped once stays on the map forever — it keeps growing across restarts, slowly building a complete picture of your world that visitors can browse from anywhere, on any device, without launching the game.

Features

• Live player markers. See who is online and where they are, updated every few seconds. Click a name in the online list to jump straight to that player and watch them uncover new land as they travel.
• Pan & zoom viewer. Drag to pan, scroll to zoom, with a coordinate readout under the cursor. Clean dark theme, works on phones and tablets too.
• Multi-world support. Every world gets its own map; switch between them with the world selector. New worlds appear automatically once a player visits them. Worlds that no longer exist drop out of the list, and a whitelist lets you choose exactly which worlds are public.
• Persistent exploration. The map never forgets: terrain stays visible even when chunks unload or everyone logs off. Over days of play it grows into a full atlas of your server.
• Completely self-hosted. The page, the tiles and all data live on your server and nowhere else. Nothing is sent to any external service.

For Admins — Setup in Two Steps

1. Drop the jar into your server's mods/ folder and start the server. That's the whole installation — the config writes itself with working defaults.
2. Open TCP port 8123 in your firewall or hoster panel (the one thing a plugin cannot do for you). The port can be changed in the config if 8123 is taken.

Then give the map your server's name — in-game, as OP:

/webmap title My Awesome Server

The name appears on the page within seconds. /webmap (OP-only) shows status and the URL to share.

Running several worlds? Pick the one the map opens on:

/webmap default <world>

/webmap default clear switches back to automatic (a world with players online).

Only want some worlds on the map? Use the world whitelist:

/webmap whitelist add <world>
/webmap whitelist remove <world>
/webmap whitelist clear

With an empty whitelist, every world is shown. /webmap worlds lists all worlds and whether they are shown or hidden.

Optional settings in mods/de.glymera_GlymeraWebMap/config.json:

• playerMarkers: false — hide live player positions from the page (privacy)
• port / bindAddress — where the web server listens
• title — the page title, if you prefer editing the file over the command
• defaultWorld — the world the page opens on (empty = automatic)
• worldWhitelist — only these worlds appear on the map, e.g. ["default", "nether"] (empty = all worlds)
• mapInstances — map temporary instance worlds such as a hub or dungeon that is spawned per visit (default: off)
• render cadence and budget — sensible defaults, no tuning needed

Good to Know

• The map is rendered from the game's own cartography at its native resolution, so it always matches what players see on their in-game map.
• Tiles render near online players only, on background threads, with a hard per-pass budget — no impact on world tick performance, and an idle server does no map work at all.
• Tiles are plain PNG files under mods/de.glymera_GlymeraWebMap/tiles/ — trivially easy to back up, and deleting them simply resets the map (it re-fills as players explore).
• Browsers cache tiles aggressively; the page only re-downloads a tile when its pixels actually changed. A handful of open map pages costs your server next to nothing.
• Works standalone — no other plugin required.
