SharedMap

A shared map layer for your server: everyone's exploration and public markers, synced through the server and saved next to the world. Your own map stays your own.

Markers

• Public marker: choose an icon and double-click the map. Everyone on the server sees it, tinted so you can tell it apart.
• Private marker: hold Left Ctrl while double-clicking. Only you see it, like vanilla.
• Make public later: hold Left Shift and left-click one of your private markers, or a greyed-out marker read from a cartography table. A plain left-click on a greyed-out marker makes it your own private (white) marker, as in vanilla.
• Cross out: left-click a marker to cross it out or undo the cross. Anyone can cross out a public marker.
• Delete: right-click a marker. A public marker can only be deleted by the account that placed it or by an admin (listed in adminlist.txt; the host of a listen server counts as admin). The server logs every deletion with the player, marker name, icon, biome, coordinates and owner.
• Duplicates: markers with the same icon and name (unnamed ones count too) within 20 m (configurable on the server) are cleaned up:
  • Between public markers, the server keeps the original and removes the new one.
  • On your own map, every marker is checked: public (gold), private (white) and cartography (grey). Gold beats white beats grey; within a colour the older marker stays.

Personal map

• Shared exploration shows as lighter fog, the same shading vanilla uses for cartography-table data. It is never written into your own exploration.
• Hiding the shared map: untick the Server shared map checkbox on the large map (above vanilla's cartography and "Visible to other players" checkboxes) (or set ShowSharedMap = false). This hides shared exploration and public markers without changing your own exploration, private markers or cartography-table data.
• Cartography tables: areas you read from a table are added to the shared exploration for everyone. Vanilla's "Cartography Table Shared map" checkbox then only shows or hides the table's pins; the fog stays under the "Server shared map" checkbox.
• Saving: public markers are never saved to your character or written to a cartography table. Your client receives them from the server each time you join.

Crossplay / network

• Map data is sent in batches of compressed changes. The initial map goes out in bands of 64 rows. Nothing is sent pixel by pixel.
• Sending pauses whenever a connection's send queue is busy, so the map never delays world and gameplay data.
• There is no version enforcement. Players without the mod, including console players, can join and are never sent map data.

Install

• Server: required. It stores the map in <world>.txcsharedmap next to the world .db file, keeping the previous save as .txcsharedmap.old.
• Clients: every player who wants the shared map. The server and clients must run the same major version.

Config (BepInEx/config/txc.sharedmap.cfg)

Notes

• Public markers are identified by icon and position, rounded to 0.5 m.
• Updating from 1.x: public copies previously saved to your character are replaced by the server's markers. Markers shared in 1.x have no recorded owner, so only admins can delete them.
• Sync is done by the clients, like the vanilla game, so a modified client could send fake data. Permissions are enforced by the server.
