Thaumcraft Inventory Scanning Mod — Reference

Core Mechanics

The mod hooks into the standard Minecraft inventory system to allow the Thaumometer to 'see' items that are not currently rendered in the world.

Scanning Logic

When a player opens a GUI and hovers over a slot, the mod checks for the following conditions: 1. The player must have a Thaumometer in their hand or attached to their cursor. 2. The item in the slot must have defined Aspects (either from vanilla Thaumcraft or other addons). 3. The player must have discovered the prerequisite Aspects required to understand the item's composition.

If these conditions are met, the standard scanning animation and sound effect play, and the item is marked as 'Scanned' in the player's knowledge base.

The "Secret" Feature

A notable hidden feature of this mod is the ability to scan the player themselves. By hovering the Thaumometer over the player's character model in the inventory screen, the player can scan themselves to discover Aspects such as Humanus, Spiritus, or Corpus (depending on the Thaumcraft version and installed addons).
