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

  - "Crate Key"
  - "Vote Token"

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_formatted% - Money spent (abbreviated: 1.5M)
%guishop_total_earned%          - Money earned (with commas)

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

Command	Description
/gs market status	View system status
/gs market info <item>	Check item's market status
/gs market reset <item>	Reset item to base price
/gs market resetall	Reset all prices

---

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.
