Some sites state that “it moves 2 ticks after the signal comes in,” but this is contrary to the facts observed in BE1.17.11.

  • Droppers send items in one tick.

    • I only turned on one tick and made sure the item moved to the next hopper.
  • Hopper sucks items in one tick.

    • I put the item in the hopper with no destination on the top and turned on the hopper on the bottom for one tick and confirmed that the item moved down
  • Hopper sucks ignoring the feed invalidation time of the upper hopper.

      • The first tick put the item in the top hopper and the second tick turned on the bottom hopper.
      • I confirmed that the item moves down on the second tick.
        • There must be a counter inside that counts the “number of ticks since the item was entered” because the sending out does not occur until 4 ticks later, but it is clear that the target counter value does not care when the item is sucked out
    • You can see that the hoppers are transported faster when lined up vertically than when lined up horizontally.
