About Unmarked

From Thunderstore

Clears the 'summoned through cheating means' mark from items and objects, on load and live as players play. Server only.

Unmarked

Unmarked

Gets rid of the "summoned through cheating means" mark, and keeps it gone.

Since Valheim 1.0, items made or found while cheats were on carry a mark, the grey line "This item was summoned through cheating means". The mark spreads: put one marked wood on a stack and the whole stack is marked, smelt marked ore and the bars come out marked, tear down a marked wall and its materials are marked.

Install Unmarked on your dedicated server and it clears the mark from your world as soon as the world loads, then keeps clearing it as people play. Your players don't install anything. It runs only on the server.


What you get

| | | |---|---| | A clean world on load | Every item in every chest, cart, ship, tombstone and item stand, every item on the ground, and every marked building piece and station is cleared as the world loads. | | Kept clean while you play | When a player's game sends the server a chest, a dropped item or a station, Unmarked clears any mark within a second, and every player's game, theirs too, gets the clean version. | | Clean your own inventory | Put marked items in any chest, close it, open it again: they come back clean. | | Clean furnace output | Smelters, blast furnaces, kilns, refineries, fermenters and cooking stations fed marked items lose their mark before anything comes out. | | Builds stop leaking marks | Pieces built with cheats are cleared, so tearing them down gives back clean materials. | | Leaves everything else alone | Only the one mark bit of each item is changed: stack, quality, crafter, slot and custom data stay as they are. Anything it can't read exactly is left untouched. | | Chests in use are left alone | A chest someone has open is cleaned when they close it, so nothing changes under their hands. | | Tells you what it found | The log says what was cleaned, where, and whose game sent it, and the player sees a short message. | | Optional: spot outside cheat tools | Switch on FlagImpossibleItems and the log names items the game could never make, like a stack of 500 wood or a quality-10 sword, with where they are and whose game sent them. Only logs. | | Optional: debug items | Switch on RemoveDebugItems to delete the developer-only items (SwordCheat, SledgeCheat and the like) wherever they are stored. | | Light on your server | Live cleaning costs next to nothing. The whole-world check runs every 10 minutes, about 0.5 ms a frame for half a minute on a world of 2.9 million objects, never more than a few ms in one frame. The log shows the numbers for yours. |


Install

You need a Valheim dedicated server with BepInEx on it (BepInExPack for Valheim). Most server hosts have a one-click option for BepInEx.

Step by step

  1. Download Unmarked-<version>.zip from

Releases.

  1. Unzip it. Inside is a plugins/Unmarked folder.
  2. Copy the Unmarked folder into your server's BepInEx/plugins folder,

so you end up with:

   <server>/BepInEx/plugins/Unmarked/Unmarked.dll
  1. Start the server. In the server log you should see:
   Unmarked 1.0.0 loaded

and, once the world has been checked:

   Unmarked: world on load: 802 marked items cleaned in 5648 objects, 5057 object marks cleaned; ...

That's it. Make a backup of your world first if you'd like to be able to go back: cleared marks are saved with the world.


Settings

Settings live in BepInEx/config/com.cocopuff2u.unmarked.cfg. The file appears after the first start. Edit it any time: Unmarked picks up the change a second after you save, and says Settings reloaded in the log.

| Setting | Unmarked default | Vanilla game | What it does | |---|---|---|---| | Enabled | true | | Turns the whole mod on or off. | | CleanOnLoad | true | marks stay forever | Clear every mark in the world right after it loads. | | CleanLive | true | marks stay forever | Clear marks from chests (once closed), carts, ships, tombstones, ground items and stands as players' games send them. | | CleanObjects | true | marks stay forever | Clear marks from stations fed marked items and from marked pieces and containers. | | RoundMinutes | 10 | | Minutes between checks of the whole world, for anything not caught live. 0 turns the rounds off. | | RemoveDebugItems | false | debug items stay | Delete the developer-only items: SwordCheat, SledgeCheat and every other item whose name ends in Cheat. | | ExtraItems | (empty) | | More items to delete when RemoveDebugItems is on, by prefab name, comma separated. | | ReportOnly | false | | Find and log marked things, but change nothing. Handy for a first look. | | FlagImpossibleItems | false | | Log items the game could never make: a stack bigger than the item's stack size, or a higher quality than it can be upgraded to. Only logs, never changes anything. | | LogEachClean | true | | A log line for each thing cleaned while people play (what, where, from whom), and a summary after each world check. | | NotifyPlayers | true | | A short message in the middle of the player's screen when items they just stored were cleaned. |

A blank means the game has nothing like it.
