About this Mod

ItemsAdderAdvancedTooltip is a simple Clientside Fabric Mod for 1.21.11 that modifies the minecraft:<id> text usually shown in Advanced Tooltips with a custom <namespace>:<id> one, if you're hovering over an item that was created by the Server Plugin ItemsAdder.

How it works

The Mod looks for the following components structure in an item:

components: {
    "minecraft:custom_data": {
        itemsadder: {
            namespace: "namespace",
            id: "id"
        }
    }
}

If such a component structure is found does the mod take the namespace and id value and use them as the Tooltip's <namespace>:<id> content, replacing the minecraft:<id> one usually displayed.

Example: Instead of minecraft:paper would it display example:custom_item.

Modpack inclusion?

This mod can be included in Modpacks, as long as you respect the MIT license and also give credit to me and this original project page.

(Neo)Forge version?

Tried to add support for NeoForge using Architectury, but due to way too many issues did I make this mod a Fabric-only version.
This mod may work on NeoForge using the Connector mod but no guarantee is provided here.
Maybe in the future will I consider a NeoForge version to be created.
