The dropper is a block that can be used to eject items, or push items into another container.

Obtaining

Droppers can be mined using any type of pickaxe. If mined without a pickaxe, they drop nothing.

Usage

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 faces toward the player.

A dropper cannot be moved by pistons,‌^{[Java and Legacy Console editions only]} and water and lava flow around a dropper.

Container

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 /data command (for example, to label a dropper at (0,64,0) "Alice's Dropper", use /data merge block 0 64 0 {CustomName:"Alice's Dropper"}).

A dropper can be "locked" (or subsequently unlocked) by setting the dropper's Lock tag with the /data 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 /data merge block 0 64 0 {Lock:"Alice's Key"}.‌^{[Java Edition only]}

Redstone component

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 does 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 that is configured to point in another direction.

In addition to the methods above, droppers can also be activated by quasi-connectivity.‌^{[Java Edition only]} A dropper activates 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 does 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 is 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 is 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. Even items that would be treated differently by a dispenser (such as arrows) are simply ejected by a dropper.

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

Block data

See also: Data values

In Bedrock Edition, 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: 0: Dropper facing down 1: Dropper facing up 2: Dropper facing north 3: Dropper facing south 4: Dropper facing west 5: Dropper facing east
0x8	Set if dropper is activated.

Block states

See also: Block states

Java Edition:

Name	Default value	Allowed values	Description
facing	north	down east north south up west	The direction in which contents are shot or dropped. The opposite from the direction the player faces while placing the block.
triggered	false	false true	True if this block is activated.

Bedrock Edition:

Name	Default value	Allowed values	Description
facing_direction	0	0 1 2 3 4 5 6 7	The direction in which contents are shot or dropped. The opposite from the direction the player faces while placing the block.
triggered_bit	false	false true	True if this block is activated.

Block entity

See also: Block entity format

A dropper has a block entity associated with it that holds additional data about the block.

• Block entity data
  • Tags common to all block entities see Template:Nbt inherit/blockentity/template
  •  CustomName: Optional. The name of this container in JSON text component, which display in its GUI where the default name ordinarily appears.
  •  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
  •  LootTable: Optional. Loot table to be used to fill the dropper when it is next opened, or the items are otherwise interacted with.
  •  LootTableSeed: Optional. Seed for generating the loot table. 0 or omitted uses a random seed.
