EzAuction is a complete, GUI-driven auction house plugin for Paper, Spigot, Purpur, and Bukkit Minecraft servers. Players list items for timed sale, create reserve-balance buy orders, and compete in real-time live broadcast auctions – all through smooth, paginated menus backed by Vault economy, MySQL or YAML persistence, PlaceholderAPI support, and optional Discord webhook notifications.

Whether you run survival, skyblock, SMP, or factions, EzAuction handles your server economy: timed listings, offline-safe item returns, enchantment-aware search, live auction sessions with one-click bidding, and team-scoped auctions via TeamsAPI.

Requires Vault and a compatible economy plugin such as EzEconomy to process currency.

What's New – v2.3.0

Live Auction Overhaul

• Live auction seller management – Players with ezauction.auction.live.sell can now queue items directly from the Live Auction browser (sell button in the GUI) or via /liveauction sell. On enqueue, a chat message confirms the queue position. /liveauction cancel removes the entry and refunds the deposit; a cancel button also appears in the GUI while the player has a queued entry. Admins with ezauction.auction.live.admin can force-cancel any active auction with /liveauction cancel <id>.
• /bid command (alias /livebid) – Dedicated command for live auction interactions: place bids (/bid <amount>), view session status, and manage per-player countdown preferences. Bids can also be placed by clicking the suggestion in the live auction chat message.
• Per-player notification preferences – Toggle countdowns with /bid notify [on|off] and select display type with /bid notify display <types…>. Preferences persist across restarts in live-preferences.yml (or a MySQL table).
• EzCountdown integration (optional soft-dependency) – Display live auction countdowns via ACTION_BAR, BOSS_BAR, TITLE, SCOREBOARD, or CHAT.
• Clickable bid messages & item hover previews – The bid announcement in chat links directly to /bid <next-minimum>; hovering the item name shows enchantments, potion effects, and shulker box contents on hover.
• Five new Bukkit events – LiveAuctionStartedEvent (cancellable), LiveAuctionBidPlacedEvent (cancellable), LiveAuctionEndedEvent, LiveAuctionPlayerJoinedEvent, LiveAuctionPlayerLeftEvent.
• Live Auctions shortcut in Auction House – A quick-access beacon button (slot 47) in the main /auction browser opens the Live Auction picker directly, without having to type /liveauction.

Fixes & Other Additions

• Claim GUI – /auction claim and the Claims button in the browser now open a 54-slot GUI showing each pending return item with its expiry date displayed in the item lore. A single Claim All button collects everything at once; a Back button returns to the auction browser.
• Configurable claim expiry – Set claim.expiry-days in auction.yml (default 7) to control how many days pending return items are held before expiry is shown in the Claim GUI.
• First-bid minimum fix – The opening bid on a live auction now only requires the starting price; the increment is applied to subsequent bids only. Sending an empty /bid response automatically places the minimum bid.

Why Use EzAuction?

!Auction House browser: paginated, searchable listings with price overlays

• Menu-first trading – Paginated browsers, sell/order editors, and confirmation popups keep every transaction guided and click-friendly.
• Listings + buy orders – Run timed sales, reserve balance for buy requests, and fulfill either side straight from the GUI or command flow.

!Buy orders GUI

!Listing editor with price and quantity controls

• Team auctions – TeamsAPI integration lets team members co-list and co-claim auctions, perfect for faction and skyblock economies.

!Team Auction GUI

• Async persistence & fallbacks – Listings and history write through dedicated executors, automatically falling back to YAML storage if MySQL is unreachable.
• Offline-safe returns – Expired or undeliverable items go to a claimable stash with login reminders and /auction claim recovery.
• Rank-aware limits – Plug in a custom AuctionListingLimitResolver service to scale slot caps with ranks, islands, or progression data.
• Smart value overlays – Surface configured price hints or pipe in EzShops buy/sell estimates directly into menu lore.

Feature Highlights

• Configurable menus & translations – Override browser/confirm layouts, filler glass, and button text across the bundled English, Dutch, Spanish, and Chinese menu files.
• Flexible storage – Start on lightweight YAML or flip to production-ready MySQL with connection pooling, SSL flags, and table prefixes.
• Asynchronous history – Background save queues batch player history writes to keep gameplay responsive, even during heavy auction traffic.
• Player protections – Deposit refunds, balance checks, expiry sweeps, and inventory-aware delivery prevent dupes and lost currency.
• PlaceholderAPI support – Drop %ezauction_*% placeholders into scoreboards, holograms, or chat to surface active listings, orders, limits, and pending returns.
• Integration-ready API – Register Bukkit services to override listing caps or provide custom value providers without forking the plugin.
• Enchant-aware search – Search sharpness v, fortune 3, or minecraft:looting to find listings and buy orders carrying exact enchantment stacks - supports roman numerals, numeric levels, namespaced keys, and underscore/space variants.
• Shulker box previews – Buyers can inspect shulker contents directly from the auction browser before purchasing.

Discord Integration

• Standalone webhook – Post colour-coded embed notifications to any Discord channel by pasting a webhook URL into discord.yml. No DiscordSRV or bot setup required.
• DiscordSRV support – Optionally route notifications through an existing DiscordSRV installation with optional account-linking and role-gating per event.
• Four event types – Receive a message whenever an auction is listed, sold, bid on, or cancelled, each styled with its own accent colour (green / blue / yellow / red).
• Live admin commands – Configure, enable, disable, and test the webhook in-game with /auctiondiscord webhook - changes take effect instantly without a restart.
• Async & non-blocking – All HTTP calls run on a background thread; a failed delivery is logged at WARNING level and never interrupts gameplay.

Hologram Features

• Permission and proximity controls – Optionally restrict hologram visibility and interaction by permission node or player proximity (distance).
• Configurable types – Choose which auction stats or listings to display via hologram type selection.

Quick Start

1. Upload EzAuction.jar, restart your Paper or Purpur server, and confirm Vault plus an economy plugin are active.
2. Edit plugins/EzAuction/auction.yml for pricing rules, durations, and GUI slots, adjust auction-storage.yml for YAML/MySQL persistence, and update auction-values.yml or messages/menu-interactions_*.yml as needed.
3. Choose between YAML or MySQL storage, then grant players ezauction.auction (and optional sell/order/history nodes) so they can browse and trade.
4. Encourage /auction history so buyers and sellers can audit their latest activity right from chat.

Live Auctions

!Live Auction Queue GUI: browse, join, or queue your own item

• Queue the spotlight listings – Flip live-auctions.enabled on (and queue-enabled if you want a rolling lineup) so fresh sales are staged for broadcast and visible through /liveauction.
• Sell from the GUI – The Live Auction browser shows a sell button for players with ezauction.auction.live.sell. One click opens the sell menu pre-configured for the live queue – no command needed.
• Queue position feedback – After queuing an item, the seller receives a chat confirmation with their position number. If the queue is disabled, the auction starts immediately and a different confirmation is shown.
• Cancel anytime – A cancel button appears in the GUI while the player has a queued entry; clicking it (or running /liveauction cancel) dequeues the item and refunds the deposit.
• Admin force-cancel – OPs and players with ezauction.auction.live.admin can stop an active auction immediately via /liveauction cancel <auction-id>. All bids are refunded and the item is returned to the seller.
• /bid command – Bidders place bids with /bid <amount> or by clicking the clickable suggestion in chat. /bid notify and /bid notify display manage per-player countdown preferences.
• Hype them in chat – Keep display-in-chat enabled to broadcast live listings every announcement-interval-ticks ticks with clickable bid links and hover previews on the item name.

• Curate from the live menu – The Live Auctions GUI shows queue position, seller names, price summaries, and highlights your own entry with a badge and enchant glow.
