Syntax

File:Data graph.svg

A graph that describes the syntax of this command.

There are four instructions for /data (get, merge, modify, remove), and the targets/sources referenced by each instruction command may be either block <targetPos>, entity <target>, or

1. REDIRECT Template:Visible anchor

Template:Code

Merge the NBT data from the target block position or entity with the specified <nbt> data.

Examples

• To view the NBT data of the player's held item:

  /data get entity @s SelectedItem

• To get the saturation level of the current player:

  /data get entity @s foodSaturationLevel

• To make the nearest item within 10 blocks unable to be picked up by players:

  /data modify entity @n[type=item,distance=..10] PickupDelay set value -1s

• To get the Y-position of a random item:

  /data get entity @e[type=item,limit=1,sort=random] Pos[1]

• To get the item ID of the item in the first hotbar slot of the nearest player:

  /data get entity @p Inventory[{Slot:0b}].id

• To change the first item in a chest located at coordinates (1, 64, 1) into a diamond block, keeping all NBT data:

  /data modify block 1 64 1 Items[0].id set value "minecraft:diamond_block"

• To make the nearest zombie have a 80% chance to drop items in its off-hand when it dies, and never drop items in the main hand:

  /data merge entity @n[type=zombie] {drop_chances:{mainhand:0f,offhand:0.8f}}

• To make the nearest zombie have an 80% chance to drop items in its off-hand when it dies, without affecting the chance for the main hand:

  /data modify entity @n[type=zombie] drop_chances.offhand set value 0.8f

List, array and string length

With

1. REDIRECT Template:Command

Template:Redr, it is possible to get the length of lists or arrays and the number of characters in strings, since its return value is the length of the string, list, or arrays being referenced. This value can then be stored using

1. REDIRECT Template:Command

Template:Redr, if necessary.

List example

Suppose a list is stored using the following command:

Template:Cmd

Then, running the following returns 6, the length of the list:

1. REDIRECT Template:Command

String example

Suppose a string is stored using the following command:

Template:Cmd

Then, running the following returns 43, the length of the string:

1. REDIRECT Template:Command
