About this Mod

Requires Arcadia Lib and Numismatics (the coin economy this AH plugs into).
English
A player-driven auction house. Sell items for coins, browse what others are listing, get paid offline. Servers sharing one MySQL database share one marketplace.
What it does
- Cross-server listings: post on A, show up on B and C.
- Mailbox tab: payouts and expired listings wait there. Open the tab, click to claim.
- Search and filters: by name, by category (All / Pets / Misc), or your own listings only.
- Top Business leaderboard: ranks sellers by unique buyers, not raw coin volume.
- 48h expiry (configurable). Expired items go to the mailbox.
- Live coin breakdown while you type the price: see "3 Crown, 2 Cog" instead of guessing what 4022 spurs is worth.

Français
Un hôtel des ventes piloté par les joueurs. Tu mets en vente, tu parcours, tu reçois ton paiement même hors ligne. Tous les serveurs branchés sur la même base MySQL partagent un seul et même marché.
Ce que ça fait
- Annonces cross-serveur : ce que tu mets en vente sur A apparaît aussi sur B et sur C.
- Onglet Boîte aux lettres : paiements et annonces expirées s'y accumulent. Tu ouvres, tu cliques, tu récupères.
- Recherche et filtres : par nom, par catégorie (Tout / Pets / Divers), ou uniquement tes annonces.
- Top Business : classement basé sur les acheteurs uniques, pas sur le volume brut.
- Expiration 48h (configurable). Les annonces qui n'ont pas trouvé preneur partent dans ta boîte.
- Aperçu en direct de la décomposition en pièces pendant que tu tapes le prix.
Commandes
/arcadia_ah | Ouvrir l'hôtel des ventes |
/arcadia_ah sell <prix> [quantité] | Mettre l'item tenu en vente |
/arcadia_ah bid <listingId> <montant> | Enchérir sur une annonce |
/arcadia_ah pricehistory [item] | Historique des prix sur 7 jours |
/arcadia_ah top | Classement Top Business |
Côté serveur
La durée des annonces, le nombre maximum par joueur, les frais de mise en vente et la blacklist se règlent dans config/arcadia-ah.toml. Les outils d'admin (activation globale, prix planchers, blacklist à chaud) sont accessibles sous /arcadia_ah pour les OP 2.
