Block Sniffer
by Vigilance
Block Sniffer is a Fabric equipment mod for finding blocks by name, with three tiers of sniffer items and an Echo Necklace.
What it does
Several items help a player locate a block they are looking for. The primary items are the Block Sniffer and the Echo Necklace, and each can search with an alternative mode that matches similar block names. Searching for a chest, for example, can also return blocks whose names contain the word chest, and the item itself is included as a block nametag.
Block Sniffer comes in three available tiers, and the higher tiers are crafted from an Emerald Block or a Diamond Block with a Block Sniffer as the ingredient. The Block Sniffer and the Echo Necklace both need a Calibrated Echo Pearl to be crafted, and the Block Sniffer items themselves need an Echo Pearl. Searches also cover blocks and items added by other mods, so modded content can be found alongside vanilla blocks.
Block Sniffer runs on client and server, so the server and every player need it. Files are published for Fabric only, for game versions 1.20.1 and 1.21.1, and the license is Creative Commons Attribution 4.0. The project is not open source.
Key features
Three sniffer tiers
The Block Sniffer is available in three tiers, with the higher tiers crafted from emerald and diamond blocks.
Echo Necklace search
The Echo Necklace offers a second item for finding blocks, alongside the Block Sniffer.
Similar name matching
An alternative searching mode matches blocks with similar names, so a search for chest also finds blocks with chest in the name.
Jukebox and note block volume
The mod can detect a sound change and adjust the volume settings of jukebox and note blocks.

The mod is compatible with modded blocks and…
