Modifier Tooltip Fix (Fabric)
If you have ever worked with custom items in Minecraft, you know how important clear tooltips are. The Modifier Tooltip Fix (Fabric) mod addresses a subtle but frustrating issue: when attribute modifiers are added through NBT data, the special equals-style tooltip used for attack damage and attack speed simply does not appear. This mod changes that, bringing consistency back to your item displays.
Why Attribute Tooltips Matter in Minecraft
In vanilla Minecraft, the default attack damage and attack speed modifiers on weapons and tools show up with a distinct equals sign style in the tooltip. This visual cue helps players instantly recognize standard modifiers. However, when those same modifiers are applied via NBT, such as through JSON recipes or commands, the tooltip reverts to a plain format. The Modifier Tooltip Fix (Fabric) for Minecraft corrects this discrepancy by ensuring the equals style is used regardless of how the modifier was added.
This is particularly useful for map makers, modpack creators, and datapack developers who rely heavily on NBT-based item customization. Without the fix, players might see inconsistent tooltips that make it harder to compare gear at a glance.
How the Fix Works Under the Hood
The mod uses two simple mixins to patch the vanilla code responsible for tooltip rendering. Specifically, it targets the UUIDs associated with the default attack damage and attack speed modifiers. When one of these UUIDs is detected on a modifier, the equals style is applied. A quirk in the vanilla code previously prevented this from happening for NBT-loaded modifiers, but the Modifier Tooltip Fix (Fabric) overrides that behavior.
Affected UUIDs
- generic.attack_damage: CB3F55D3-645C-4F38-A497-9C13A33DB5CF
- generic.attack_speed: FA233E1C-4180-4865-B01B-BCCE9785ACA3
These are the exact UUIDs used by the default modifiers. The mod watches for them and ensures the correct tooltip style is rendered, no matter the source of the modifier.
Supported Minecraft Versions and Fabric Loader
The Modifier Tooltip Fix (Fabric) is built for the Fabric loader, which means you will need Fabric API and a compatible Fabric installation. Builds are marked with the Minecraft version they were compiled for, and they will work for that specific version. Because the mod consists of only two lightweight mixins, it is highly likely to remain compatible with future Minecraft releases and snapshots. If a new version breaks compatibility, the developer encourages users to leave a comment so an update can be issued.
For players who prefer a streamlined setup, the foxygame.net launcher offers a one-click install option that automatically places Modifier Tooltip Fix (Fabric) into your mods folder without any manual file management. The launcher also maintains an add-on catalog with auto-updates, so your version compatibility stays current with each Minecraft release.
How to Install Modifier Tooltip Fix (Fabric)
Installing the mod is straightforward. First, ensure you have Fabric Loader installed for your Minecraft version. Then, download Modifier Tooltip Fix (Fabric) from a trusted source and place the JAR file into your mods folder. Launch the game with the Fabric profile, and the fix will be active immediately. No configuration is required.
If you are using a launcher like foxygame.net, the process is even simpler: browse the add-on catalog, select Modifier Tooltip Fix (Fabric), and let the launcher handle the rest, including automatic updates and version matching.
Note for Mod Developers
If you wish to include this fix in your own mod, you must use Loom's include configuration to package it within your JAR. The mixin used in this mod cannot coexist with other copies of itself, so proper packaging is essential. Since the developer lacks resources to host a Maven repository, JitPack is the recommended alternative.
Conclusion
The Modifier Tooltip Fix (Fabric) is a small but valuable addition for anyone who works with NBT-based attribute modifiers in Minecraft. It restores visual consistency, improves readability, and requires virtually no effort to install. Whether you are building complex datapacks or simply want your custom gear to look right, this mod delivers a clean, reliable solution for Fabric users across multiple Minecraft versions.
