Mojang Keeps Re-Adding This AMAZING Bug

For some reason, Mojang keeps re-adding an amazing new redstone bug(?) that let's us detect what item the player is holding!

If you can use this with noteblocks, and each slot. You've essentially just created a working piano in Minecraft.

[@nikj1178]

Exactly what I was thinking, imma make it

[@Speaker-Beater]

convenient that the hotbar is 9 slots too, you can make one entire scale and have an extra note left

[@BlueHazeBurnout93]

⁠​⁠@@Speaker-BeaterIf the hotbar was 10 slots, you could make an entire scale and even have 2 extra notes left.

[@catovr]

@@BlueHazeBurnout93 Now get this, if it was 11 slots, you could make an entire scale and even have 3 extra notes left

[@Saiyana]

I think the delay is a bit too long for that, its something like half a second or less but still enough to make it really hard to play anything

[@arcanine_enjoyer]

Just remember to prevent the villager from ever getting back to its work station or else it will refresh its trades the following day

[@random832]

Most of the potential here is for custom maps with custom villagers anyway.

[@itskdog]

​@@random832 custom maps wouldn't need to worry about this as they could use commands, though. I'm seeing this more as a survival thing.

[@connerkb8497]

I suppose that could also be used as an advantage, for something like randomized puzzles or codes.

[@Pickled_Poet]

​@itskdog I can see it as both for vailla and puzzle making. Id use it as a control panel for a factory or multiple Redstone contractions. I like the right click feature of edible items

[@jan_harald]

@@Pickled_Poet custom maps can already check every inventory slot of the player with command blocks though, so it's only for SURVIVAL puzzle making ;P

[@lucidmoses]

I would think it's intentional as they would have to program it specifically to give it the response number (4). To be sure, I would check the data pack modding systems and see if there is a corresponding type of entry for it. That would prove intention but sadly if absent doesn't prove it wasn't. I can't see it being a bug for sure but unintentional.... slight maybe.

[@devil1ndisguise_]

maybe they accidently added it and its supposed to be added in a future "bigger" update like 1.21

[@witha1]

maybe the 4 has to do with a specific set of mob events and villagers pulling out an item classifies under that

[@kmb600]

According to the Wiki, "Villager holds item" falls under the "Entity Action" game event.

I suspect that the reason this works is because of the entity_action event, which was added in 23w31a to be a general selector for all unique things that a particular entity can do. The wiki lists Ravagers roaring and wolves shaking as the things it replaces, but elsewhere it says that camels sitting/standing, turtles digging, and witches using potions are detectable under that event as well. It’s not hard to imagine that someone could have thought “Oh hey, villagers have a unique action that they can take, I should put that in there too.”

[@Nuttist]

I love tech like this in minecraft. almost feels like not-a-bug and I hope its here to stay!

[@KBRoller]

It seems intentional for the sculk sensors to pick up the villager equipping/unequipping vibrations. Whether the devs realized the power of that, though, I don't know, but I don't think they'll remove it. This is really cool tech! 😁

[@sylv256]

it’s a bug. of course they’ll remove it. if it doesn’t work in bedrock then they’ll definitely remove it.

[@joshsatterwhite1571]

This feels like a return to the old school Sarc content I subbed for. I honestly do enjoy the suggestion and opinion style pieces, but your mechanical videos are the best of their kind on all of KZbin. This one especially is phenomenal, and I hope this ends up being an accidental feature that stays in the game, and not a bug that gets patched out.

[@FluffyFoxUwU]

i agree but i think a bug should be fixed and re-add properly as a feature as bug maybe result from consequences of something entirely different

[@CraftyMasterman]

how did i not know about this??????? this is so cool

[@Mr_Mimestamp]

This is really cool, great find! I can finally make a secret entrance that requires players to eat a potato to enter!

[@Protofall]

This reminds me of the carrot door Etho made in his LP years ago. Basically a rabbit on a lead under a wall/door and when he held the carrot, the rabbit would go hyper, tug towards the door and hit a pressure plate activating the door. That said, I think eventually he gave up on it and just added a button to that door. The door is in his Lab leading to the brick/water/leave hallway.

[@SiggyTundra]

I'm curious if this works with renamed items. If it does. Imagine using items as keys in adventure maps with this.

[@Florian87]

I don’t actually know for sure, but I’m certain it does work, you simply set up a custom villager trade with commands. Although checking if the player is holding an item is something you can already with command blocks, which is a lot more convenient, making the villager trick kinda pointless for this purpose

[@osman8950]

@@Florian87 im pretty sure this mechanic ignores NBT data

[@SmokeFactory]

@@osman8950yeah it does, plus using this mechanic would make the key randomly unlock if you’re near the door, rather than you actually selecting to use it (which COULD be annoying)

[@theai_1]

I mean, with adventure maps you have commands that can detect held items anyway, so it doesn't really help all too much there

[@Lordofbones96803]

@@theai_1Just wondering what command that would be because that would be very useful

[@prizegotti]

I noticed each Copper Bulb had a different note. Would it be possible to get 9 villagers, give each one a different individual trade, fill up your hotbar and use your 1-9 keys as a midi keyboard?

[@SimplySarc]

Yea, there were some noteblocks underground :) And sure I think that's doable!

[@TomParkes1993]

noteblock has 25 pitches. with good enough coordination, 3 players could play a wider range.

[@kaelanirevyruun1676]

​@michael23b add a series of sensors then :P

[@ninja-ed8mj]

The number 4 is the "mob exclusive action" frequency, so since only villager type mobs can Doo that I'm guessing it's not a bug but a feature

[@kadenspencer-smurthwaite9006]

[@jackmercenary]

[@PicklesBaby]

As somebody who has been Redstoning for almost 8 years now, this feels like magic.

[@Imverybadatyoutube]

Really neat, don't play Minecraft much anymore but it certainly is interesting for more wireless redstone capabilities. Even if it is a bug (ahem Copper bulbs) they should keep it as it's very interesting with a lot of potential uses for redstone builders.

[@JacobP81]

6:27 I get it now. Looking at the Sculk Sensor Minecraft article I can understand this. The 3 diffrent villager sending vibration level 4 must be detected with 3 different Skulk Sensors you have hidden. this is paired with the vibration level 8 (the eating vibration) to detect what you are eating does setting off the correct firework. Very clever.

[@jasonrubik]

At 5:25 when you said that "there's a way to take control of the player's scroll wheel", I thought that you meant that the game would prevent the player from scrolling thru their hotbar, and that the game itself (the redstone) would be moving the selected hotbar item. I think that what you really meant was "that there's a way for the player's scroll wheel to take control of the redstone". A minor distinction, but one which might confuse non-native English speakers. This is an awesome and amazing discovery ! I hope this bug is a feature !

[@user-ud5zj5jg4m]

Wow that is a powerful mechanic! Will definitely give it a try. Btw I think you can distinguish the code item from an emerald by having 2 villagers with different trades triggering 1 isolated sculk sensor each. And plug in a comparator so when the secondary sculk gets triggered it blocks the signal from the main villager. Also am I the only one who thought of combination locks?

[@monkeyblade99]

Neat. So you could recreate up to 9 note instruments with this....

[@KBRoller]

8, really; you need an empty slot to switch to or else you can't do the same note twice in a row.

[@Max_Power_]

@@KBRoller Or just play the note when you right click the item, then you can use all 9 slots.

[@nicholass5621]

Better than exhausting the other trades to to deactivate the emerald reaction you could have 2 villagers that respond to different items. So if they both react, you're holding an emerald and the door doesn't open but if you hold just the right item, then it opens.

[@dasneko7218]

This reminds me of the stairs collision detection bug that could do the same thing. Basically by having an item on top of a stair that was pushed up and down by a piston the behavior of the item was different depending on if you had the item held in your hands or not. I can't remember it clearly but I think the item normally floated above the stair as if it was a full block but once you held it then the item fell down onto the lower stair which you could detect with a nearby pressure plate. The biggest difference is that the item was not really important so you could use anything rather than being limited to villager trade. Do not think the bug still works sadly.

minecraft in minecraft could actually become much easier to run with this, pressing buttons to do stuff, heck you could even add a whole system to control it for you that takes inputs and transfers them to item slot positions.

Good to know that if I want to get past these doors all I need to do is get my pet ravager to yell at it. And it will open

For a bit of context, "vibration frequency" 4 for a calibrated sculk sensor is listed as "Gliding with an elytra or unique mob actions". This includes stuff like wolves shaking themselves after getting wet, ravager roars, amongst other things. Unfortunately this does mean that any door you have locked behind this mechanic can simply be opened by flying into it. AWESOME tech potential for my elytraless world though. Nice video Sarc, cheers!

[@BenjaminGoldberg1]

You would need to fly near the particular Skulk Sensor to activate the door. If the villager is standing slightly below ground level, and the Sensor is far enough below the villager that nothing above his feet can be heard by the Sensor, you and your elytra will be out of luck.
