Minecraft displays the player inventory differently, according to how the window was opened. Ranges of slot indices vary in meaning between different “windows”. The Open Window packet indicates which window is being opened according to:

  • 2Chest
  • 4Furnace

  1. Baubles is a small mod and API by Azanor, which was temporarily taken over by Vazkii until Azanor returned, that is meant to be used by other mods to add additional player inventory slots. The Baubles inventory can be accessed by pressing the B key, by default.
  2. Format slot 0 of player with skull of Sam1370 named ' &c Owner: &c S &6 a &e m &a 1 &b 3 &9 7 &1 0' to be unstealable Somehow format slot just doesn't like me. Am I doing something wrong?
  3. Inventory slots refer to a unique equipment or bag slot. For equipment, slot names are resolved to a slot id constant with GetInventorySlotInfo. This gives Blizzard more flexibility to change slot ids. InventorySlotName also doubles as a GlobalString Graphical Explanation (Classic) Example.
The following information needs to be added to this page:
Most of the inventories new to 1.14 have buttons, which are probably implemented using Protocol#Click Window Button. This needs to be confirmed and the button IDs should be checked.

RealPC mod for Minecraft PE 0.11.0RealPC adds to the game a few useful things! Now, in the inventory of creativity you can find all the available items that developers have not yet added. In addition it will be a new opportunity - 32,000 slots in the inventory mod for MCPE 0.10.5It is a simple mod, but it will be in your inventory slots 32k.

The slot number is calculated starting at 0, counting up through the window's unique slots, and then counting through the players inventory.

For all windows, the slot in the upper-left corner of the player's inventory is slot n where n is the number of unique slots, and slot number -999 is always used for clicking outside the window.

The default inventory window, which is never explicitly opened by the server, has 10 unique slots.

Rectangular regions are always indexed starting with the upper-left corner and scanning across rows. If a window has a crafting region, the output slot is always slot 0 followed immediately by the input region.

Each window type is described in the following sections. All slot index ranges are inclusive and reflect the indices observed in the Minecraft protocol.

For the window properties (additional data in each window, e.g. smelting progress or enchantments), refer to the table in the Window Property packet.

Using -1 as slot index and as window id will set the cursor item (the stack dragged with the mouse).

Player Inventory

Inventory slots

This is the inventory window that the player can always open, typically by pressing E since Beta 1.4. Before, you had to press I.

Slot rangeDescription
0crafting output
1–42×2 crafting input (1 + x + 2 * y)

Note that this is different from inventory items stored in a player.dat file. This may help: https://gist.github.com/459a1691c3dd751db160

Chest

Chest slots

This is the window that is opened when the player right-clicks on a single chest block.

Large chest

This is the window that is opened when the player right-clicks on a double chest block (two adjacent chest blocks).

Slot rangeDescription
0–53chest
54–80main inventory
81–89hotbar

It is possible to receive different 'Number Of Slots' parameters than those two. In vanilla, using /setblock four times around a chest and then opening the middle chest will open a window with 5*27 chest slots. Some custom servers will send chest inventories with other sizes, usually ranging from 1 row to 6 rows. These may be used for custom GUIs. It is thus important to correctly use the 'Number Of Slots' parameter in the open window packet to determine the number of rows in the chest, rather than hardcoding what constitutes a regular chest or a large chest.

Crafting table

Crafting table slots

This is the window that is opened when the player right-clicks on a workbench.

Slot rangeDescription
0crafting output
1–93×3 crafting input (1 + x + 3 * y)
