How it works

Each rising edge transfers one stone directly into the barrel. A held input transfers only once. This is container transfer, so it does not depend on dropped-item physics.

  1. An activation schedules the dropper action.
  2. When a receiving inventory is in the output direction, the dropper attempts to transfer an item into it.

Inputs and outputs

  • Inputtransfer pulse (x 0, y 0, z 0)
  • Inputrefill dropper (x 2, y 0, z 0)
  • Outputbarrel (x 3, y 0, z 0)

Blocks you need

1 × lever, 1 × redstone dust, 1 × dropper, 1 × barrel.

Build it in the game: 5 commands

Relative to where you stand, with x running east and z running south. Paste one line at a time into chat, or into a chain of command blocks. The block art is the game's own; the layout is what the page above shows.
