About this Mod

Copy Block ID

Source Patreon

A minimal client-side utility mod for NeoForge 1.21.1 that lets you copy registry IDs directly from Minecraft with Ctrl+C.

You can copy hovered inventory item IDs, JEI/REI ingredient IDs, fluid IDs, and optionally the targeted block or entity ID in the world. When something is copied, the mod shows a short in-game notification.

Example

minecraft:dirt

Features

  • Copy hovered inventory item IDs with Ctrl+C
  • Copy hovered JEI and REI ingredient IDs
  • Copy hovered fluid IDs from supported tooltips
  • Optionally copy the targeted block ID in the world
  • Optionally copy the targeted entity ID in the world
  • Client-side only
  • Lightweight and fast
  • Does not interfere with chat or focused text fields

Config

CopyBlockId creates a client config file:

config/copyblockid-client.toml

Available options:

copyTargetedEntityInWorld = false

Set either option to true if you want Ctrl+C in the world to copy the ID of the block or entity you are looking at.
