Inventory Slot Plugin Minecraft

This Minecraft villager inventory plugin for spigot and paper servers allows players to interact with villagers’ inventory. Supports any server with Bukkit API: Spigot, Paper etc. Tested Minecraft Version: 1.16.4. By default the villagers in vanilla Minecraft have 8 inventory slots. Suggested name: UCC Inventory Lock What I want: I run a creative Minecraft server that uses the clock to easily access commands on the fly at any time. I need some type of plugin that will lock the 9th inventory slot from being modified (or dropped), and for a clock to always be there, but all other inventory slots to be accessible. Add a Hidden Slot in the players inventory So, what I mean by hidden is a slot, you can't access in your inventory BUT you can access it via /data, /loot and /replaceitem. Also, you should be able to add modifiers. This would make it possible so you don't have to use an armor or weapon slot to e.g. Give a player extra health.

A GUI is an in-game screen with which has interactive objects. It consists of text fields, images, buttons, slots etc.

GUI Properties

There are 5 properties:

• GUI Width: The width of your GUI (in pixels)
• GUI Height: The height of your GUI (in pixels)
• GUI Type: 2 options: With Slots or WIthout Slots. If you select With Slots, you will be able to create slots (Input and output slots) and inventories.
• Render background layer: Check this box if you want a backgound (Grey-White color). If not, uncheck the box.
• Bind GUI to block: If you want to make a Tile Entity, you have to choose the block with the option for inventory activated.

GUI Components

There are 6 components:

• Buttons: The buttons are objects with events. This event works like the normal events.
• Images: Just images from your PC.
• Text Label: Plain text that supports MCreator's default tags for some variables (both in-game and global MCreator's variables). The text can also be colored.
• Text Input: A section where the player can write any text and can be detected and used to execute events, example uses are like a custom command block or search function.
• Input Slot: Description below
• Output Slot: Description below

Slots and Inventory Components

To create a slot (input or output) you must first enable inventory, with the Inventory Option:

Inventory Slot Plugin Minecraft 1.12.2

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

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

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.

Blast Furnace

The GUI that appears when a blast furnace is opened. Same layout as a furnace; however, the recipe book displays blast furnace recipes instead of regular furnace recipes.

Smoker

The GUI that appears when a smoker is opened. Same layout as a furnace; however, the recipe book displays blast furnace recipes instead of regular furnace recipes.

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

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

Inventory Slot Plugin Minecraft 1.8

Inventory Slot Plugin Minecraft 1.8.9

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.
