Exchange Wands

✨ Features

🔍 Select Any Block

Sneak + RMB a block to set it as your source block. The wand remembers your selection and shows a clean actionbar message.

🔄 Replace Blocks with Flood‑Fill Logic

RMB a block to replace all connected blocks of the same type. The wand uses a safe, optimized flood‑fill algorithm that respects:

• block properties (facing, waterlogged, lit…)
• inventories (chests, barrels, furnaces…)
• NBT data (restored when compatible)
• tile entity transfers
• survival inventory limits
• durability and cooldowns

🎨 Property‑Preserving Replacement

Exchange Wands copy all shared blockstate properties automatically. Orientation, waterlogging, lit state, slab halves - everything transfers seamlessly.

• the wand only replaces blocks you have
• it removes one item per exchange
• it drops overflow items safely

This mod was originally developed for Minecraft 1.20.1. I am gradually migrating it to newer versions, ensuring each update is stable, polished, and fully adapted to the latest APIs.
