The backstory

Back during the mob vote, me and my friends wanted the Tuff Golem to win. It was, for us, the most reasonable to have: "3D item frame, customizable, helps story telling (which was kind of the point of 1.20) and Mojang can't let us down by under-delivering features".

Sadly, we ended up getting the Sniffer. With the only addition of TWO decorative plants, we felt as if it wasn't worth having in the game. That was, of course, with the exception of one weirdo, MaxiTaxi_323, who is obsessed with Sniffers, playing all day to farm them, giving them stupid names and talking about it in vc. One day, one of my friends got tired of him, broke and said: "Say no more" said the programmer (that's me!!1!), "I'll make them worth having in the game".

The features

High on Sugar

• Right Click a Sniffer with sugar in your hand to make them sniff it. They'll go crazy for a bit before exploding and dropping a Potion of Sniffing.
  
  
• Giving the Sniffer more sugar while it's running will make the explosion bigger. But be careful, don't give him way too much!

Potion of Sniffing

• Drinking a Potion of Sniffing will make you sniff for ores, revealing them to the player for some time. This feature was inspired by the Potion of Spelunking Datapack by DanMizu. The sniffing effect supports:
  • All (vanilla) ores
  • Deepslate variants
  • Nether ores
  • Budding Amethyst
  • Ancient Debris (sniffing in the nether lasts fewer seconds to balance the mechanic)
• Splash and Lingering variants of the potion can also be brewed, having the corresponding intensity and duration mechanics for each of them.
• Ore revealing has two modes: (Check them out in the gallery)
  • Block Mode just outlining the block (with block displays).
  • Item Mode showing the ingots (with item displays).
  • Item Mode showing the raw minerals (with item displays).
  
  
• Admins have access to commands to get the potion, its variants and effect for integration, compatibility, testing or debugging purposes. (e.g. CommandAPI)
  • /sniff <duration> <range>
  • /potionofsniffing [potion|splash|lingering]
• Since this effect is basically a temporary X-ray, if you’re worried that someone might be using an actual X-ray, you can turn on a logging feature in the settings. It’ll show a message in the console, informing about the use of the effect.

Slime Chunk Sniffing

• In slime chunks, Sniffers are able to dig up slime balls, making for a great vanilla-friendly slime chunk detector.

Translations

• String translation support for the Potion of Sniffing.

The extra info

There's info on what customization options are available in the documentation tab. If you have another idea for making the Sniffer worth having, don't hesitate to share it here or in the repo's discussions.
