🗺️ MapShare

Version 1.1.1 · all the mods · install it from Thunderstore (r2modman, Thunderstore Mod Manager) or the in-game mod manager (F7)

Share the map you uncover with everyone in the world, live, as you run through the fog. New players get the whole map when they join.

One map for everyone: what each player has explored, and their pins

Playing on a server

General/AllowSharing is the server's when the server has this mod: turned off there, nobody's map is shared while they play on it. A server without the mod sends nothing, and each player's own settings apply.

🔍 How it works

Share the map you uncover with everyone in the world, live, as you run through the fog of war.

How it works

• The cartography table only shares a map by hand: you write your map to the table, then others read it one visit at a time. This mod does it automatically instead.
• Every few seconds, the new parts of the map you uncovered are sent to the other players and appear on their maps.
• When someone joins, one of the players already there sends them the whole map, and the newcomer sends theirs back, so everyone ends up with the same explored area.
• Only the explored area is shared, not pins. Players without the mod do not take part.

Settings: turn sending or receiving on or off, and how often updates go out.

📜 Changes

• 1.1.1 A new id, com.quad.mapshare (it was com.dhack.mapshare): your settings move over by themselves the first time it starts, and the old settings file is kept as a backup. Restart the game after this update. If an old copy is still installed beside it, this one stands down and says which file to delete, so the two never both run. The DLL now says it was made with AI, as Thunderstore asks.
• New: General/AllowSharing, decided by the server in multiplayer: a server where everyone should explore for themselves can turn map sharing off for all. Fix: a map that arrived only partly (its sender left) was kept in memory for the rest of the session, and a shared map is now only unpacked up to the size of this world's map, so nobody can send something that unpacks to a huge size.
• Fix: a player joining could miss the map explored so far when someone online did not have MapShare or had sharing off. Everyone who shares now sends it.
• First version: live sharing of the explored map between players, plus a full sync when someone joins.

1.1.5

• Settings: edits to the config file now apply while the game runs (a server owner no longer has to restart), and a server's admins can change the server's settings from their own game with Configuration Manager, where other players see them greyed out. Your config file always keeps your own values while you play on a server (saving it there could write the server's in). Players on an older version still get the server's settings.

1.1.4

• Less network traffic when someone joins. Only one player sends the newcomer the whole map now; the others send just what the newcomer still lacks (usually nothing), instead of every player sending their whole map at once. Maps also go out at a gentler pace, so the newcomer's world loads without a flood of map pieces. Works with older versions on the same server, and everyone still ends up with the same explored area.

1.1.3

• Its reload message in chat follows the game's language.

1.1.2

• A clearer page: what it does, who needs it in multiplayer, how it gets on with other mods, and where to report a bug. The game itself is unchanged.

1.1.1

• A new id, com.quad.mapshare (it was com.dhack.mapshare): your settings move over by themselves the first time it starts, and the old settings file is kept as a backup. Restart the game after this update. If an old copy is still installed beside it, this one stands down and says which file to delete, so the two never both run.
