Advanced NBT Tooltips

Minecraft is a game of endless depth, but much of its most valuable information remains hidden beneath the surface. Every item, block, and entity carries NBT (Named Binary Tag) data that dictates its behavior, yet the vanilla game rarely shows you these details. The Advanced NBT Tooltips mod changes that, transforming how you interact with the game by surfacing crucial metadata exactly when you need it. Whether you are a map maker, a technical player, or simply curious about the inner workings of your world, this add-on is an indispensable tool.

What Does Advanced NBT Tooltips Reveal?

This mod goes far beyond the basic F3+H debug screen. It dynamically displays context-sensitive information as you hover over items in your inventory, inside containers, on armor stands, in item frames, or even on the ground. The goal is to provide immediate, actionable data without cluttering your screen. Here are some of the standout features you will encounter:

• Suspicious Stew Effects: Instantly see which potion effect a suspicious stew will grant, including its duration. No more guessing if that flower-fed mooshroom stew will heal or harm you.
• Lodestone Compass Tracking: Hover over a lodestone compass to view the exact coordinates and dimension of the linked lodestone, making navigation across vast worlds effortless.
• Book and Sign Details: Check the number of pages in a written book or read the full text of a copied sign without placing it down. Command block settings are also displayed, saving you from opening the interface repeatedly.
• Entity and Spawn Egg Info: See the number of bees inside a hive or nest, and inspect modified spawn egg data to understand exactly what creature will emerge.
• Hidden Property Exposure: The mod reveals properties that are normally concealed by HideFlags, such as enchantments, attribute modifiers, and unbreakable status. You can even remove these HideFlags restrictions entirely.
• CustomModelData and RepairCost: For map makers and resource pack creators, seeing CustomModelData values at a glance is a game-changer. RepairCost is also shown, helping you manage anvil expenses.

How to Install Advanced NBT Tooltips

Getting started with this powerful utility is straightforward. The mod is designed for the Java Edition of Minecraft and supports modern versions, including the widely used 1.18.2 and 1.19 releases. It is built for the Fabric mod loader, ensuring smooth performance and compatibility with other popular optimization mods. To install, you will first need to set up the Fabric Loader and the Fabric API. Then, simply place the downloaded Advanced NBT Tooltips jar file into your mods folder. If you are using a custom launcher like the one from foxygame.net, you can often find Advanced NBT Tooltips in its built-in add-on catalog, allowing for a one-click installation that automatically handles version compatibility and updates. After launching the game, the tooltips will appear immediately when you hover over any item.

Customizing Your Tooltip Experience

One of the most powerful aspects of this mod is its flexibility. You are not limited to the default tooltips. Advanced NBT Tooltips allows you to create, load, and even override tooltips using JSON files within your resource packs. This means you can design custom tooltips that display exactly the NBT data you care about, formatted in a way that suits your playstyle or map-making needs. The mod also includes a configurable HUD that shows tooltip information when you aim at armor stands, item frames, or dropped items, so you never have to pick something up just to inspect it.

Using the In-Game Configuration

Pressing the default hotkey (B) opens a dedicated configuration screen. Here, you can toggle all custom tooltips on or off, giving you complete control over what information is displayed. This is especially useful when you want to temporarily declutter your screen during intense gameplay moments. The mod also supports translations, with community-provided language files for Chinese and German already included.

Advanced Features for Map Makers and Server Admins

If you create custom maps or manage a server, Advanced NBT Tooltips is a must-have. The ability to see CustomModelData values at a glance speeds up resource pack development. You can also inspect the command stored in a command block without activating it, which is invaluable for debugging complex command chains. The mod’s JSON-based tooltip system allows you to define tooltips for specific items or NBT patterns, making it a powerful tool for documenting your custom content directly in the game.

Why You Should Download Advanced NBT Tooltips

This mod bridges the gap between casual play and technical mastery. It eliminates the need to constantly open external editors or memorize NBT structures. Whether you are checking the repair cost of your enchanted gear, verifying a spawn egg’s entity data, or simply satisfying your curiosity about a suspicious stew, the information is right there at your cursor. The mod is lightweight, actively maintained, and integrates seamlessly into your existing mod setup. For those who want to dive even deeper, the ability to write custom JSON tooltips opens up endless possibilities for map-specific HUDs and item descriptions.

Performance and Compatibility

Advanced NBT Tooltips is built with performance in mind. It only processes tooltip data when you hover over an item, so it won’t impact your frame rate during normal gameplay. The mod is compatible with most major optimization and content mods, and the developer actively addresses issues reported on the GitHub issue tracker. If you encounter a bug or have a feature request, the community-driven development process ensures that your voice is heard.

For players who want to take their Minecraft knowledge to the next level, Advanced NBT Tooltips is an essential addition. It turns hidden data into visible, actionable insights, making every aspect of the game more transparent and enjoyable. Whether you are a seasoned modder or a curious newcomer, this tool will change the way you see your world.
