Item Info Command

The /gs iteminfo command is a powerful debugging and configuration helper. Hold any item and run the command to see:

• All lore lines
• Enchantments in config-ready format (e.g., SHARPNESS:5 UNBREAKING:3)
• Potion info in config-ready format (type, splash, extended, upgraded)

This makes it easy to configure complex items - just create the item you want, then use /gs iteminfo to get the exact format needed for your shops.yml.

          id: STONE               # Material ID

GUI-Based Item Editor

GUIShop features a powerful, fully GUI-based item editor that eliminates the need for manual config editing. Configure every aspect of shop items through intuitive click-based menus.

How It Works

1. Enter creator mode with /gs edit (for menu) or /gs edit <shop> (for shops)
2. Left-click to drag and drop items - move items within the shop, rearrange positions, or place new items from your inventory into the shop
3. Right-click or Shift+click any item to open the Item Editor GUI
4. Click on any setting to modify it through chat input or nested selection GUIs
5. Changes save automatically when you close the inventory

Creator Mode Controls

Left-click     - Pick up / place items (works between shop and your inventory)
Right-click    - Open Item Editor for the clicked item
Shift+click    - Open Item Editor for the clicked item

Navigation Buttons (pagination, back, balance):
Left-click     - Pick up and move the button
Right-click    - Open Item Editor for the button
Shift+click    - Activate the button (navigate pages, go back, etc.)

Item Editor Features

• Buy/Sell Prices - Set prices with support for abbreviated formats (1k, 1.5M, 100B)

Worth Display System

GUIShop includes a powerful worth display feature that shows item sell values directly in the item lore. This uses packet manipulation to display worth client-side only, meaning your actual items are never modified.

Requirements: PacketEvents plugin

Worth Display Configuration (worth.yml)

enabled: true
format: "&7Worth: &a%worth%"
position: BOTTOM
add-blank-line: true
only-show-sellable: true
not-sellable-format: "&7Worth: &cNot sellable"

# Hide worth in specific inventories
blacklisted-inventories:
  - "Auction House"
  - "Crate Preview"

# Hide worth on items with specific names
blacklisted-item-names:
  - "Crate Key"
  - "Vote Token"

# Hide worth on equipped armor
hide-armor-slots: true

Advanced Item Types

Command Items

Sell commands that execute when purchased. Use placeholders like {PLAYER_NAME}, {PLAYER_UUID}, {PLAYER_WORLD}, or any PlaceholderAPI placeholder:

'19':
  type: COMMAND
  id: NETHER_STAR
  shop-name: '&6VIP Rank'
  buy-price: 10000
  sudo: false          # Run as console (default) or as player (true)
  commands:
    - 'lp user {PLAYER_NAME} parent set vip'
    - 'broadcast {PLAYER_NAME} purchased VIP!'

Statistics & PlaceholderAPI

GUIShop tracks player shop statistics and integrates with PlaceholderAPI for use in scoreboards, holograms, and chat.

Tracked Statistics

• Total money spent (buying from shops)
• Total money earned (selling items)
• Total items bought/sold
• Top 3 most bought items per player
• Top 3 most sold items per player

Available Placeholders

%guishop_total_spent%           - Money spent (with commas)
%guishop_total_spent_formatted% - Money spent (abbreviated: 1.5M)
%guishop_total_earned%          - Money earned (with commas)
%guishop_total_earned_formatted% - Money earned (abbreviated)
%guishop_items_bought%          - Items purchased count
%guishop_items_bought_formatted% - Items purchased (abbreviated)
%guishop_items_sold%            - Items sold count
%guishop_items_sold_formatted%  - Items sold (abbreviated)
%guishop_top_bought_1%          - #1 most bought item (Material: Qty)
%guishop_top_sold_1%            - #1 most sold item (Material: Qty)

Statistics are stored in SQLite (plugins/GUIShop/Data/player_statistics.db).

Dynamic Pricing System

GUIShop includes a built-in supply/demand economy system that makes item prices fluctuate based on trading activity.

How It Works

• When items are bought: Supply decreases → prices increase
• When items are sold: Supply increases → prices decrease
• Over time: Prices gradually normalize back to base values

Configuration

Enable in config.yml:

dynamic-pricing: true

Configure in dynamicpricing.yml:

price-change-per-item: 0.01    # 1% change per item
max-price-multiplier: 2.0      # Up to 200% of base price
min-price-multiplier: 0.5      # Down to 50% of base price
normalization-rate: 0.001      # How fast prices return to normal
normalization-interval: 300    # Seconds between normalization ticks

Per-Item Overrides

Configure different volatility settings for specific items:

item-overrides:
  DIAMOND:
    price-change-per-item: 0.005  # More stable (0.5% per item)
    max-price-multiplier: 1.5
    min-price-multiplier: 0.75

Linked Pricing

Make items affect other items' prices - perfect for crafting relationships:

item-overrides:
  DIAMOND_BLOCK:
    affects:
      DIAMOND: 9.0           # 1 block = 9 diamonds in crafting
      DIAMOND_ORE: 1.0       # Also affects ore prices
  
  BREAD:
    affects:
      WHEAT: 3.0             # 1 bread = 3 wheat in crafting

When a player buys 1 DIAMOND_BLOCK, DIAMOND prices change as if 9 diamonds were bought. This creates realistic economic relationships!

Per-Item Control

Exempt specific items from dynamic pricing:

'0':
  id: DIAMOND
  buy-price: 100
  sell-price: 50
  dynamic: false  # Uses static pricing

Admin Commands

Developer API

GUIShop provides a comprehensive API for developers to integrate with:

// Check if an item can be sold
boolean canSell = GUIShopAPI.canBeSold(itemStack);

// Get buy/sell prices
BigDecimal buyPrice = GUIShopAPI.getBuyPrice(itemStack, quantity);
BigDecimal sellPrice = GUIShopAPI.getSellPrice(itemStack, quantity);

// Sell items programmatically
GUIShopAPI.sellItems(player, SellType.COMMAND, items);

// Worth Display API
BigDecimal worth = GUIShopAPI.getItemWorth(itemStack);
BigDecimal stackWorth = GUIShopAPI.getStackWorth(itemStack);

// Per-player worth toggle
GUIShopAPI.toggleWorthForPlayer(player);
GUIShopAPI.enableWorthForPlayer(player);
GUIShopAPI.disableWorthForPlayer(player);

// Hook for persistent per-player worth settings
GUIShopAPI.setExternalWorthCheck(player -> {
    return myPlugin.hasWorthDisabled(player.getUniqueId());
});

Full API documentation available on the Wiki.
