The '''Slot''' data structure is how Minecraft represents an item and its associated data in the [[Protocol|Minecraft Protocol]].
The '''Slot''' data structure defines how an item is represented when inside an inventory window of any kind, such as a chest or furnace.
 
This page presents the new Slot data structure, using structured components. You can find the documentation of the old structure, that utilizes raw NBT data, [[Special:Permalink/18899|here]].

The Slot data structure defines how an item is represented when inside an inventory window of any kind, such as a chest or furnace.

This page presents the new Slot data structure, using structured components. You can find the documentation of the old structure, that utilizes raw NBT data, here.

Format

Name Type Meaning
Item Count {{#switch: User:WinX64/Slot Data Data types = 
       VarInt
#default = 
       VarInt
   }}
The item count. Every following field is only present if this value is greater than zero.
Item ID {{#switch: User:WinX64/Slot Data Data types = 
       Optional
#default = 
       Optional
   }} {{#switch: User:WinX64/Slot Data
Data types = 
       VarInt
#default = 
       VarInt
   }}
The item ID. Item IDs are distinct from block IDs; see Data Generators for more information.
Components with data {{#switch: User:WinX64/Slot Data Data types = 
       Optional
#default =

Data types = 
       NBT
#default = 
       NBT
