Community Item Trade Values

The community suggests what items trade for with villagers at brennan.games/dungeontrain/items, and approved values ship in the next build of the mod.

Since: v0.1055.0 (PR #1696); the page lives in the relay (dp-relay PR #618).

How It Works

  • Browse. The page lists every item in the game (3374 at launch) with its inventory icon, its trade value in emeralds, and what a villager actually pays for it, for example "villager: 22 → 1 emerald".
  • Suggest. Log in with Discord (Dungeon Train server members only) and press Suggest on any item. Type either the value in emeralds or the trade you want ("Villagers pay [N] item → [M] emeralds"); the other side fills in as you type. A reason is required. One open suggestion per person per item; suggesting again replaces it.
  • Vote. On someone else's suggestion, press Support or Reject and say why. One vote per person per suggestion. The tally and everyone's reasons are public, and suggestions sort best-supported first. You can't vote on your own suggestion, and changing or withdrawing a suggestion clears its votes.
  • Approve. Approvers (Discord ids in the relay's ITEM_VALUE_APPROVER_IDS) approve or reject each suggestion from the same page, or set and reset a value directly. Approving one suggestion closes the others on that item.
  • Ship. Approved values reach players when a developer pulls them into the mod and builds it. See Development: community item trade values.

Technical Notes

  • Units. Values are Trade Everything's integer sixteenths of an emerald (16 = one emerald).
  • The villager line. Trade Everything pays 75% of value (result_multiplier 0.75, shown as "33.3% extra"), rounds down to whole emeralds, batches cheap items and pays dear ones in emerald blocks. The page shows the with-rounding figure next to the exact margin. public/dungeontrain/items/trade-quote.js ports TE's TradePricer; a relay test requires it to match the game's own quote for every item in the catalog.
  • In the mod. compat/TradeValueTable reads the bundled data/dungeontrain/trade_values.json and is registered as Trade Everything's first value provider, so an approved value beats DT's hand-tuned constants (TradeEverythingBridge) and TE's defaults.
  • Relay API (cap-less, /api/dp-relay/items/): values, export, me, auth/*, suggest, withdraw, vote, and approver-only approve, reject, set, clear. See the dp-relay README section "Item trade values".
  • Login. Same Discord application as the whitelist page, on its own cookie mount with redirect https://brennan.games/api/dp-relay/items/auth/callback.
