QuickBuy Addon - Overview

The QuickBuy Addon is a personal shop companion for Sigma Orders & Auctions that lets each player configure up to 54 quick-buy slots, each targeting a specific item from the live auction house. One click on a configured slot instantly purchases the cheapest currently active listing — no browsing, no manual searching.

What It Does​

Every player gets their own private shop layout. Each slot is bound to a material the player chooses, with an optional per-item price cap and optional minimum enchantment requirements. When a player clicks a configured slot, the addon queries the live auction in real time, finds the cheapest qualifying listing, and calls the core plugin's buy() method — the same path a normal auction purchase takes, with the same balance checks, delivery, and confirmation. The shop GUI then refreshes immediately to reflect the new auction state.

Key Features​

Per-Player Configurable Shop​

  • Each player independently configures their own layout of up to 54 slots (server-configurable, multiple of 9)
  • Slots are private, persisted per-player as YAML, and survive restarts
  • Unconfigured slots show as a green glass pane invite; locked slots (beyond permission allotment) show as red

Real-Time Cheapest Listing Purchase​

  • One click finds and purchases the cheapest active listing for that slot's material at that moment
  • If the targeted listing was just bought by someone else in a concurrent request, the addon silently falls through to the next-cheapest candidate — no error, no failed click
  • The buyer's own listings are never matched

Dialog-Based Material Picker (1.21.6+ Java clients)​

  • Shift-clicking a slot (or clicking it in edit mode) opens a sleek scrollable Dialog UI with an embedded search box
  • Every item the auction accepts loads at once in a single scrollable grid — the client scrolls natively, no page reloads. Items the auction can never hold (spawn eggs, command blocks, barriers, anything on the auction blacklist) are not offered
  • Real vanilla item textures render inline in the buttons for 1.21.9+ clients on a 1.21.9+ server, no resource pack needed. Older clients get plain text labels
  • Items with applicable enchantments advance to a dedicated enchantment requirement screen with per-enchantment level dropdowns

Automatic Client Fallback​

  • Bedrock clients (via Floodgate) and Java clients below protocol 771 (pre-1.21.6) are detected automatically — via the ViaVersion API when installed, not the bridged Bukkit protocol
  • Those clients get a fully independent chest-GUI + chat picker: material browsing by page, enchantment selection by chest-GUI, price input by chat with a title/subtitle overlay
  • Everything in it works with plain taps, so touch and controller players can do all of it

Optional Per-Slot Price Cap​

  • Each slot can have a max price per item, or be left unlimited ("No Limit") to always buy the absolute cheapest listing regardless of price
  • The slot lore shows "No Limit" in place of a price when uncapped
  • Prices can be typed as 1500, 1,500, 12.5, 10k or 2.5m; type none (or leave the box empty in the Dialog) for no limit — see Price input

Enchantment Requirement Matching​

  • Require specific enchantments at a minimum level (≥) on the purchased item
  • Enchanted books are handled via EnchantmentStorageMeta separately from regular item enchantments, and the picker offers every enchantment for them
  • Custom enchantments from other plugins or datapacks are supported and are saved with their full namespaced key
  • Required enchantments are shown in the slot's lore for quick reference

Edit Mode​

  • Change or delete a configured slot with plain clicks: tap the lever in the shop's last slot (shown when that slot is locked for you) or run /quickbuy edit, then tap the slot
  • Built for Bedrock and touch players, who have no shift-click. Shift-click still works for Java players

Permission-Based Slot Allotments​

  • Server admins configure how many slots each permission group can use
  • Conflict resolution always takes the highest matching limit — no permission conflicts
  • Slots beyond the player's allotment are shown as locked (non-interactive)

Configurable Command Aliases​

  • /quickbuy ships with /qb as a built-in alias
  • Additional aliases can be added to config.yml under command-aliases — effective after a restart, no rebuild needed

Fully Config-Driven​

  • Every chat message, lore line, GUI title, Dialog label, and button text lives in config.yml
  • Translate, rebrand, or tweak without touching code

Folia-Safe​

  • Uses EntityScheduler for per-player work and AsyncScheduler for background I/O throughout
  • No Bukkit.getScheduler() calls

How It Works​

Setup (one time per slot):

  1. Run /quickbuy (or /qb) to open your personal shop
  2. Click an empty slot to configure it. To change a configured slot, shift-click it, or turn on edit mode (/qb edit) and click it
  3. Search for and pick the material you want to auto-buy
  4. Optionally set minimum enchantment levels on the purchased item
  5. Enter a max price per item (1500, 10k, 2.5m ...), or leave it empty / type none for no limit

Daily use:

  1. Open /quickbuy — each slot shows live availability, quantity, price-per-unit, and total cost
  2. Click any configured slot to instantly buy the cheapest matching auction listing
  3. The slot refreshes after every click — what you see is always current
