True Hopper

• 1.21 Crafter-style slot locking, single-block 5-item filtering, and bulk top-off.
• Clean, vanilla-native logistics without redstone spaghetti.

Features

• 20 Items/Second Throughput (Hopper Minecart Parity):
  • Built with a 1-tick transfer engine to match hopper minecart transfer speeds.
• 1.21 Crafter-Style Slot Locking:
  • Click any empty slot with an empty hand to seal it. Prevents unwanted items from ever entering or clogging your line.
• Filtering:
  • Click a locked slot while holding an item to assign a ghost filter. Preserves the item on your cursor.
• Single-Block 5-Item Sorter:
  • Filter up to 5 distinct items in a single hopper block.
• Bulk Pull Top-Off:
  • Pulling items into the hopper tops off matching stacks instantly to match hopper minecart speeds.
• Full Redstone Parity:
  • Full vanilla redstone and comparator support with zero changes or quirks.
• Round-Robin:
  • Cycles slot-by-slot to keep transfers balanced and vanilla-friendly:
  • Transfer speed naturally scales up the more slots you dedicate to an item (up to 20 items/s across all 5 slots).
  • Single slots or mixed sorting lines retain a slower, controlled rate.
