Instead, hoppers with multiple dropped items above them collect the items in the order in which they entered the chunk in which the hopper is located. Items that drop from a broken armor stand are collected in a random order. Hoppers usually check for dropped items every game tick and they can collect items even before they are picked up by a player [ verify ] or destroyed by lava.
However, in Bedrock Edition hoppers have a "collection cooldown" time. After collecting an item or stack of items , a hopper waits 4 redstone ticks 0. Hoppers collect groups of items all at once rather than collecting them as single items one at a time. As a result, hoppers can collect item entities much faster than they can pull items from a container. Pulling from a moving minecart with chest or minecart with hopper is even slower, since the minecart is not always above the hopper.
A hopper with a storage container above it such as a furnace , chest , dropper , composter , or another hopper attempts to pull from the container instead of checking for floating items above it, and hence can not collect items. A hopper always tries to push or pull items using the leftmost available slot. When a hopper is removing items from a chest, the items disappear from left to right. Similarly, when filling up a chest, the chest fills up from left to right.
Hoppers prioritize pulling from the first slot of a container over pulling into the first hopper slot. If a hopper has stone in its first slot and nothing in its second while the container it is pulling from has chicken in its first slot but stone in the second, the hopper pulls the chicken from the first slot of the container into its empty second slot. However, if the hopper is unable to pull the chicken, such as if all slots are filled with stone, the hopper pulls the stone from the second slot of the container instead.
Similarly, hoppers prioritize pushing from their first slot over pushing into the first slot of a container. If a hopper has stone in its first slot and chicken in its second while the container it is pushing to has chicken it its first slot but stone in the second, the hopper pushes stone from its first slot into the second slot of the container.
The checks done by a hopper while pulling generally require less processing than the checks done by a hopper attempting collection. Placing composters with no storage slots but still with custom output logic on top of hoppers provide the greatest efficiency, while double chests actually degrade performance, even when sharing each double chest across two hoppers. Push then Pull. Item pushes and pulls are processed in the same game tick, but pushes are processed before pulls.
In the schematic, the empty hopper first pulls an item from chest A as it cannot push anything into chest B. After the cooldown, the hopper first pushes its item into chest B before pulling another item from chest A, both pushing and pulling in the same tick, and the process repeats.
The hopper stops pulling when A is empty, and stops pushing when B becomes full. Hoppers also have a "transfer cooldown" time. A hopper that has an item pushed into it from another hopper also starts a 4 tick cooldown period, regardless of whether it pushed or pulled items itself. Item entities can be collected at any time without affecting the transfer cooldown time. The transfer cooldown and the Bedrock Edition collection cooldown are independent of each other.
Some containers interact with hoppers in specific ways:. Bedrock Edition : [ needs in-game testing ]. In Bedrock Edition , a hopper uses its block data to specify its orientation and activation status. The 13w02a Banner includes a minecart with TNT and a hopper.

A Hopper Hoppers are a block that can pick up items thrown into the top or can remove and transfer items from adjacent containers and deposit them into another container. You can see the output is connected to the chest by the small piece that juts out of the bottom of the hopper. Items that the hopper pulls will sit in the hopper inventory until it has an output to push the items out into. The top chest is full of cobblestone and the hopper below it will pull cobblestone out of the chest and feed it into the furnace below it.
The furnace will cook the cobblestone and as the resulting stone gets cooked, the hopper below it will pull the stone out of the furnace. Finally, this hopper will feed the cooked stone into the chest at its side. Ensure that the hoppers have something to pull from and push into. Otherwise, it will simply be a glorified chest that only holds five inventory slots.
A hopper will transfer items from above to below at a rate of 2. Hold sneak to prevent opening the chest with right-click. With the hopper selected in your Hotbar simply hold sneak and right-click the chest in order to put the output of the hopper towards the chest.
A hopper in a minecart will check items above the rail for potential inputs. If you place a chest above the rail the hopper will pull items from that chest. It will not output items, but you can place another hopper below the track to pull from the minecart with a hopper. You can use a hopper in a minecart to travel upwards, but there is no way to connect only hoppers and go upwards. You can utilize an item elevator made with blocks, water, and fence posts to push items upwards, but this is a separate device from hoppers.
A hopper on its own cannot drop items into lava. You can feed the hopper into a dropper that is positioned over lava for an automated incinerator. Yes, a hopper will feed items into a furnace. It is not smart enough to detect which items can be fuel or which items are used for smelting and instead places every item it gets in its inventory into the top slot of a furnace.
You will have to refuel your furnaces afterward. Hoppers have three main functions that they operate with. However there are some popular uses that many players utilize frequently in their builds. The top 3 uses for Hoppers are:. You can do this manually or setup other automations that drop items on top of the Hopper setup.
