[MC-207251] Sculk sensors and shriekers do not work correctly when cloned, generated on superflat worlds or placed with custom structures

Using a flat world with preset minecraft:bedrock,2*minecraft:dirt,minecraft:sculk_sensor;minecraft:plains causes all sculk sensors not to work. Only sculk sensors you placed react to sound.
The sculk_sensor_phase tag seems to be on inactive forever.

i know this isn't an intended bug, but what if there is/will be a way to make them being on cooldown toggleable, like you can use something to "turn them off" and im not talking about wool occulsion. Maybe a glow squid drop? something that can pad them in a gel like substance?

Is this still an issue in snapshot 21w05a or later?

Avoma 2021-02-04T16:51:35Z

Yes, this is still an issue in 21w05a.

Avoma 2021-02-15T09:04:45Z

Can confirm in 21w06a.

alphaimetal0903 2021-02-26T02:24:04Z

Can confirm in 21w08a,b

Avoma 2021-02-27T17:35:00Z

Video attached.

Avoma 2021-04-14T14:54:14Z

Can confirm in 21w14a.

CalXee 2021-04-23T20:55:55Z

@Avoma I've noticed in the video you attached, the sculk sensor phase is on Inactive which is strange because the sculk sensors are still not activating...

bowser2lux 2021-05-13T13:52:41Z

Can confirm for 21w19a

The problem also exists when, for example, the command "/ fill" is used

ampolive 2021-07-06T21:10:39Z

Can confirm on 1.17.1, but in my world sculk_sensor_phase is on inactive instead of cooldown.

ampolive 2021-09-28T23:02:16Z

Can confirm in 21w38a.

MMK21 2022-03-19T07:15:24Z

Affects 22w11a. /fill seems to not have this issue

SamtheBKBoss 2022-04-19T04:13:48Z

The issue is different now. Sculk Sensors generated in a standard or single-biome world work perfectly. This issue only applies to superflat worlds, as well as Sensors generated as part of a custom structure. In these specific cases, as of 22w15a, the sensors had "sculk_sensor_phase" set to "inactive," not "cooldown," but they still don't quite work until an entity steps on them. As soon as they're stepped on, they work perfectly again.

SamtheBKBoss 2022-04-21T13:56:27Z

Correction from my previous comment: sensors generated in custom structures are slightly different from those in superflat worlds. In superflat worlds, they begin working like normal after being stepped on by any mob once, whereas in structures, they work when stepped on, but NEVER resume normal ranged functionality.

To be honest, I could totally see the developers making superflat sensors work like this on purpose so as to not overload the game with sensor activation on world generation.

gnembon 2022-04-26T07:41:07Z

You are correct, Sensors are 'off' in the flat worlds due to special treatment of block layers in flat worlds only. This is not a new issue since the same is happening if you create a world of hoppers for example. This is still a valid issue, just more general and not isolated to sculk sensors.

The other issue is saved state of sensors in structure files. Sculk sensor is one of those annoying blocks that need some extra manual treatment, for example removing of last vibration data to work properly. This is similar to other blocks of this type, like loot chests, with the extra care here that sculk sensors cannot be tripped before saving, or need to be cleaned manually afterwards.

SamtheBKBoss 2022-04-26T13:20:26Z

@Gnembon Wasn't expecting a Mojang response on my random comment... thanks for the insight! For structure files, I assume the fix is the same for MC-249450?

MMK21 2022-04-27T17:58:26Z

Sculk Shriekers and Structure Blocks should be mentioned in this report (see MC-250670, which was resolved as a duplicate of this one)

aceplante 2022-07-23T18:47:27Z

Deleting the last vibration data didnt work, as it just defaults to 0

Oxibaros_ 2022-08-05T20:14:53Z

I can fix it!
U need a delete one value in .nbt (i use NBTExplorer)

Edit this and delete coordinates in this "pos"

user-f2760 2023-03-26T09:12:53Z

Also affects control+pick block.

ampolive 2023-03-26T11:16:44Z

Ctrl + pick block is tracked at MC-249450.

Ray 2023-04-05T19:04:19Z

also doesnt work with structure blocks
