LootBuyer is a resource buyer GUI for Paper and Purpur. Players open /buyer and sell their loot to the server. Prices rotate on a timer, every item has its own per-player limit, ranks can earn more, and admins can see who sold what.

Features

• Clean menu. Every item shows its price, the change since the last rotation (▲/▼ in %), how many you can still sell and how many you have.
• Fast selling. Left click sells 1, right click sells a stack, shift-click sells everything. "Sell all" button and /buyer sellall command.
• Rotating prices. A random price within the range you set, rotated on a timer with a chat announcement.
• Anarchy mode. Optionally buy only a random set of items each rotation (items-per-rotation).
• Per-player limits that reset with every rotation, so farms can't flood your economy.
• Rank multipliers. Give lootbuyer.multiplier.vip and that player earns ×1.1 (configurable).
• Sales history for admins. /buyer history <player> shows every sale with date, item, amount and money, plus totals. Choose how many days to keep it, or turn it off.
• Safe by default. Only plain items are bought: renamed, enchanted or custom items from other plugins are left alone. Armor and off-hand are never sold, and items can't be taken out of the menu.
• Persistent. Prices and limits survive restarts.
• Works across versions. Paper and Purpur 1.16.5 – 26.x. Items that don't exist in your version are skipped automatically.
• Localized. English and Russian included, plus your own languages. Item names show in each player's client language where the server supports it. Every line is configurable with MiniMessage (gradients, hex colors).
• PlaceholderAPI support and works with Citizens NPCs.

Requirements

• Paper or Purpur 1.16.5 – 26.x (forks of Paper work too)
• Java 8 or newer, whatever your server version requires
• Vault and an economy plugin (EssentialsX, CMI, …)
  • On 1.16.5 use EssentialsX 2.20.1: newer EssentialsX doesn't support 1.16.5
• PlaceholderAPI — optional

Not supported: plain Spigot, Folia.

Configuring items

language: en            # en, ru or your own lang/<code>.yml
rotation-minutes: 60
items-per-rotation: 0   # 0 = all items, 7 = random 7 each rotation
items:
  diamond: { material: DIAMOND, price: [90, 140], limit: 128 }
  bone:    { material: BONE,    price: 2,         limit: 0 }   # fixed price, no limit

Run /buyer reload after editing. If you change an item's price range, a new price is picked right away.
