JEI Integration Mod — Guide

Mechanics and Integration

The mod functions as a "plugin" for JEI. It hooks into the JEI API to register categories and handlers that other mods may have neglected to implement.

Recipe Handlers

While JEI handles most vanilla recipes, many complex modded machines require custom handlers to display their inputs and outputs. JEI Integration acts as a catch-all support layer, ensuring that machine recipes, specialized crafting altars, and chemical processors from various mods appear correctly in the JEI recipe overlay.

Technical Utility

For modders and pack developers, the Translation Key and NBT Data tooltips are the most critical mechanics. The Translation Key allows translators to identify exactly which string needs to be localized in .json or .lang files. The NBT Data tooltip allows developers to see the exact tags required for specialized item filters in mods like Applied Energistics 2 or Refined Storage.

Frequently Asked Questions

Q: Does this mod work with Fabric? No. JEI Integration is designed exclusively for the Forge mod loader.

Q: Why are no tooltips showing up after I installed the mod? By default, all tooltips are set to "Disabled" to prevent cluttering the player's screen. You must enter the configuration file or the in-game config menu to enable the specific tooltips you wish to see.

Q: Is there a performance impact? The performance impact is negligible. The mod only calculates tooltip data when the player hovers over an item in an inventory, and the recipe handlers are indexed during the game's startup phase.
