Obtaining[επεξεργασία | επεξεργασία κώδικα]
Droppers can be mined using any pickaxe. If mined without a pickaxe, it will drop nothing.

Usage[επεξεργασία | επεξεργασία κώδικα]
A dropper can be used as a container or as a redstone component to move items.
To place a dropper, use the Place Block control. A dropper can be placed so that its output faces in any direction, including up or down. When placed, the dropper's output will face in the direction it was placed from.
A dropper cannot be moved by pistons,[Computer and Console editions] and water and lava will flow around a dropper.
Container[επεξεργασία | επεξεργασία κώδικα]
A dropper has 9 slots of inventory space.
To open the dropper GUI, use the Use Item control. To move items between the dropper inventory and the player inventory or hotbar while the dropper GUI is open, drag or shift-click the items. To exit the dropper GUI, use the Esc control.
By default, the GUI of a dropper is labeled "Dropper". A dropper's GUI label can be changed by naming the dropper in an anvil before placing it, or by using the blockdata command (for example, to label a dropper at (0,64,0) "Alice's Dropper", use blockdata 0 64 0 {CustomName:"Alice's Dropper"}
).
A dropper can be "locked" (or subsequently unlocked) by setting the dropper's Lock
tag with the blockdata command. If a dropper's Lock
tag is not blank, the dropper cannot be accessed except by players holding an item with the same name as the Lock
tag's text. For example, to lock a dropper at (0,64,0) so that only players holding an item named "Alice's Key" can access the dropper, use blockdata 0 64 0 {Lock:"Alice's Key"}
.
Redstone component[επεξεργασία | επεξεργασία κώδικα]
- See also: Redstone circuit
A dropper can be used to eject items, or push items into another container.
- Activation
- A dropper can be activated by:
- an adjacent active power component (Exceptions: a redstone torch will not turn ON a dropper it is attached to)
- an adjacent powered opaque block (strongly-powered or weakly-powered)
- a powered redstone repeater or redstone comparator facing the dropper
- powered redstone dust configured to point at the dropper, or on top of it, or a directionless "dot" next to it; a dropper is not activated by adjacent powered redstone dust which is configured to point in another direction.
- In addition to the methods above, droppers can also be activated by quasi-connectivity. A dropper will be activated if one of the methods above would activate a mechanism component in the block above the dropper, even if there is no mechanism component there (even if the block above the dropper is air or a transparent block), but only when the dropper receives a block update (including a redstone update within two blocks of the dropper).
- A dropper will not activate if it has been less than 1 redstone tick (2 game ticks, or 0.1 seconds barring lag) since its last activation ended.
- Behavior
- When activated, a dropper waits 2 redstone ticks (4 game ticks, or 0.2 seconds barring lag) and then ejects one item from its inventory. The dropper does not continue to eject items while activated -- ejection occurs only on the initial activation (the rising edge of an input signal). To eject multiple items, repeatedly activate the dropper with a clock circuit.
- If multiple slots are occupied by items, a random occupied slot will be chosen for ejection. The slot is chosen when an item is ejected, not when the dropper is initially activated, thus it is possible to move items into or out of a dropper between its activation and item dispensing.
- If the dropper is facing a container, the ejected item will be transferred into the container. Otherwise, the item is ejected in the direction the dropper is facing, as if a player had used the Drop control.
- A dropper makes a clicking noise (the
random.click
sound event) when activated empty or when ejecting items into air, but is silent when it successfully transfers an item into another container.
A dropper is an opaque block, so powering it directly can cause adjacent mechanism components (including other droppers) to activate as well.
A line of droppers, each pushing items into the next dropper, is known as a dropper pipe. A dropper pipe must be clocked to move items, but can be clocked to move items faster than a hopper pipe's transfer rate. When a dropper pipe pushes items upwards, it is known as a droppervator (short for "dropper elevator").

Data values[επεξεργασία | επεξεργασία κώδικα]
A dropper has a numeric ID of 158 in the PC edition, and 125 in the Pocket Edition.
A dropper has an ID name of minecraft:dropper
, and is further defined by its block data and block entity. A dropper also has a block state which is expected to replace the functionality of block data in a future version.
Block data[επεξεργασία | επεξεργασία κώδικα]
- See also: Data values
A dropper's block data specifies its orientation and activation status:
Bits | Values |
---|---|
0x1 0x2 0x4 |
A three-bit field storing a value from 0 to 5 specifying which direction the dropper is facing:
|
0x8 | Set if dropper is activated. |
Block entity[επεξεργασία | επεξεργασία κώδικα]
- See also: Block entity format
A dropper has a block entity associated with it that holds additional data about the block. The block's block entity ID is dropper
.
- Block entity data
- Tags common to all block entities see Template:Nbt inherit/blockentity/template
- CustomName: Optional. The name of this container, which will display in its GUI where the default name ordinarily is.
- Lock: Optional. When not blank, prevents the container from being opened unless the opener is holding an item whose name matches this string.
- Items: List of items in the container.
- : An item, including the slot tag. Dropper slots are numbered 0-8 with 0 in the top left corner.
- Tags common to all items see Template:Nbt inherit/item/template
- : An item, including the slot tag. Dropper slots are numbered 0-8 with 0 in the top left corner.
- LootTable: Optional. Loot table to be used to fill the dropper when it is next opened, or the items are otherwise interacted with.[note 1]
- LootTableSeed: Optional. Seed for generating the loot table. 0 or omitted will use a random seed.[note 1]
Block state[επεξεργασία | επεξεργασία κώδικα]
