How to Create and Reload Custom Tooltips with a Resource Pack

Setting Up the Tooltip File

To build custom tooltips, you define them inside a standard Minecraft resource pack. Create a JSON file at the following path:

assets/<namespace>/datatip/datatip.json

Replace <namespace> with minecraft or your custom pack namespace. Inside this file, specify which items receive tooltips. Data Tip Mod allows you to target items using three methods:

• Exact Item IDs: Apply tooltips directly to specific items.
• Item Tags: Group multiple items together using standard Minecraft tags.
• Wildcard Patterns: Target broad groups of items matching pattern rules.

Within each definition, add your desired text lines, custom fonts, bold formatting, and colors.

Applying Changes In-Game

You do not need to restart your Minecraft client to test your updates.

1. Save your changes to datatip.json.

2. Return to the game and press F3 + T to reload your resource packs (or run the /reload command).

3. Open your inventory and hover over the targeted item to view your new custom tooltip.

All text styles and custom elements will refresh immediately upon reloading.
