Slot

A slot is a location in the data of a block entity or entity that an item stack can be placed in.

Java Edition
A slot is defined by its slot index.


 * {| class="wikitable sortable" data-description="Slot Index"

!Slot index !Used by !Description
 * 0-53
 * General inventories
 * Different containers have different ranges for the slot number:
 * Chests, dispensers, droppers, hoppers, and trapped chests are numbered 0 for the top-left slot and then increase first horizontally, then vertically (so, for example, a chest's top row slots are numbered 0 to 8 from left to right). Double chests and double trapped chests are treated as two single container blocks.
 * A brewing stand's bottom slots are numbered 0 to 2 from left to right, its top slot is 3 and the fuel slot is 4.
 * A furnace's slots are numbered 0 for the input slot, 1 for the fuel slot, and 2 for the output slot.
