Bazaar Villager Mod

The Bazaar Villager Mod introduces an advanced, fully server-side trading system centered around a new type of NPC: the Bazaar Villager. Instead of randomized vanilla trades, Bazaar Villagers function as personal shopkeepers, allowing players to configure their own item stocks and set custom prices up to 10,368 emeralds.

Unlike normal villagers, Bazaar Villagers do not wander, cannot die, and cannot be pushed — they act as secure, persistent NPC vendors.

Key Features

- Custom Player-Owned Bazaar Villagers

• Players can place items inside their Bazaar Villager and assign a price for each slot with a custom GUI
• Prices support:
  • Emeralds
  • Emerald Blocks (×9)

Advanced Currency System

• The mod introduces Emerald Core Blocks, crafted from 9 emerald blocks.

  • 1 Emerald Block = 9 Emeralds
  • 1 Emerald Core Block = 81 Emeralds
• Prices up to 128 Core Blocks (10,368 emeralds) are supported.

🔄 Smart Auto-Payment & Overpayment Handling

When a buyer selects a trade:

• The system automatically pulls the smallest possible combination from the player’s inventory.
• Supports mixed payment (emeralds, blocks, cores).
• Overpayment is allowed and fully supported. You will receive change if you pay too much!

Buyers receive change intelligently:

• As many Core Blocks as possible
