GetStackInSlot(side:number, slot:number):table Returns a table describing the item in the specified slot or nil. Deprecated for getting info about robot's own inventory, see getStackInInternalSlot. Side - must be a valid side. Slot - the slot to analyze. This does not check the inventory size and will consider slots outside the inventory bounds. I am, of course, playing the newest version of Minecraft. Thank you in advance for your help, ArthurPhoenix:3. Edit: Thanks to the people who have commented so far, I learned that replacing 'Inventory' with 'SelectedItem' tests for the item held by the player instead of executing the command if it is placed in any inventory slot. Specifies the item to be placed in the block or entity's inventory slot. Must be an item id, or a block id for which an item exists (for example, minecraft:goldensword). Minecraft Ids 1.12.2 amount (BE: amount: int) (optional) Specifies the number of items to be placed in the block or entity's inventory slot.

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

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 number of unique slots in the window is sent in the Open Window (Play, 0x2d, clientbound) packet for all storage windows (e.g. Chest, Dropper). For non-storage windows (the items get dropped when the window is closed, e.g. Workbench, Anvil), the received number of unique slots is always 0, but it can be looked up by the client from the window type.

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

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.

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

Chest

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).

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

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

If the 'Number Of Slots' parameter is not set to 0, the opened window will behave like a container window.

Furnace

The window that appears when a furnace is right-clicked.

If the 'Number Of Slots' parameter is inferior to 3, placing an item in a slot may crash the client.

Dispenser

The inventory that appears when a dispenser or dropper is opened.

If the 'Number Of Slots' parameter is inferior to 9, placing an item in a slot may crash the client.

Enchantment Table

The inventory of an enchantment table. The enchant buttons trigger a Enchant item packet.

Brewing stand

Inventory Slot Id Minecraft

The GUI that appears when a brewing stand is opened.

Villager trading

The GUI that appears when a villager is right-clicked. Note that if the villager only requires one item, you can put it in either (or both) slots.

Beacon

The window that appears when a beacon is right-clicked.

Anvil

Hopper

The window that appears when a hopper or hopper minecart is opened.

Shulker box

This is the window that is opened when the player right-clicks on a shulker box chest.

Llama

The inventory that appears when a tamed llama is right-clicked and has a chest, or when the player's inventory is opened while riding a tamed llama. Depending on the value of the strength field, the number of chest rows may vary (max is 5, so 15 slots).

There still is a saddle slot, even though it cannot be used and is invisible.

Slot positions within the llama inventory vary - slot 2 may be at (1,0) or at (0,1) depending on the number of columns.

• Unchested llama

• Llama with strength 1

• Llama with strength 2

• Llama with strength 3

• Llama with strength 4

• Llama with strength 5

Horse

The window for when a tamed horse is right-clicked or the player's inventory is opened while riding a horse.

• Horse slots

• Skeleton horse slots

• Zombie horse slots

Donkey

The inventory that appears when a tamed donkey (or mule?) is right-clicked, or when the player's inventory is opened while riding a tamed donkey or mule.

There still is an armor slot, even though it cannot be used and is invisible.

• Unchested donkey

• Chested donkey

• Unchested mule

• Chested mule
