Shulker Box Tooltip Mod — Guide
Key Features
The mod offers several distinct viewing modes and utility features to help players track their resources:
- Dynamic Previews: Instantly see icons and stack counts for every item inside a container.
- Color Matching: The preview window's border and background adapt to the color of the Shulker Box (e.g., a Lime Shulker Box will have a lime-themed tooltip).
- Inventory Fullness: Displays a summary of how many slots are occupied versus the total capacity.
- Loot Table Detection: For technical players, the mod can display the internal loot table name of a container (disabled by default).
- Creative Mode Support: Works seamlessly with containers obtained via the 'Pick Block' (Ctrl + Middle Click) command, showing their saved NBT contents.

Controls and Interaction
Interaction with the tooltips is handled through configurable hotkeys. By default, the mod uses the following keybindings:
| Action | Keybinding (Default) | Description |
|---|---|---|
| Compact Preview | Shift |
Shows a condensed list of items and their total counts. |
| Full Preview | Alt + Shift |
Displays a full 3x9 grid exactly as it appears inside the box. |
| Lock Tooltip | N |
Keeps the preview window open even after moving the mouse. |
| Toggle View | V |
Cycles through different tooltip styles (Compact, Full, or Hidden). |
| Tool Info | Left Alt |
Displays detailed durability and enchantment data for tools inside the box. |
Note: These keys can be remapped in the standard Minecraft Controls menu or via the mod's configuration screen.
Mechanics and Logic
Preview Styles
The mod utilizes two primary rendering methods for tooltips:
- Compact Mode: This mode groups identical items together. If you have three stacks of Cobblestone, it will show a single Cobblestone icon with the number '192'. This is ideal for bulk storage boxes.
- Full Mode: This mode mimics the actual container GUI. It shows the exact slot placement of every item, which is useful for organized kits or shulker boxes containing varied equipment.
While the mod is primarily client-side, installing it on a server enables the Ender Chest Preview. Because Ender Chest contents are stored per-player on the server, the client cannot normally see them. With the mod on the server, it securely syncs your Ender Chest data to your client for the preview to function.
Supported Containers
Shulker Box Tooltip is designed to be compatible with almost any container item. Supported vanilla items include:
- All 17 colors of Shulker Boxes
- Chests and Trapped Chests
- Barrels
- Furnaces, Blast Furnaces, and Smokers
- Dispensers and Droppers
- Hoppers
- Ender Chests (Requires server-side mod)
Mod Compatibility
The mod features an API that allows other mod developers to add support for their own backpacks, crates, and storage bags. It is widely compatible with popular storage mods, ensuring that modded backpacks display previews in the same style as vanilla Shulker Boxes.
