Sculk sensor wool occlusion has directional bias
The bug:
Sculk sensors have a bias when detecting sounds from certain directions when wool is in the way. It seems the x axis is different from the z axis, where the x axis blocks sounds and z does not from diagonals

Hey there!
Does MC-207289 describe your issue?
Since this describes your issue, this report is a duplicate of MC-207289
Isn't this the same issue as MC-207289?
Yeah, its the same issue, but my report is about the bias on vertical diagonals while MC-207289 only covers for the diagonals on same y level.
I did it mostly for the sake of completion, you can close this one if its not helpful at all.

The sculk sensors have a bias when detecting vibrations from certain directions when wool is in the way. It seems the x-axis is different from the z-axis, where the x-axis blocks vibrations and z does not from diagonals.
How to Reproduce
- Make the following setups based on the attached image.
- Press the levers and see the responses.
Observed Result
The sculk sensor wool occlusions only block vibration from the north/south.
Expected Result
The sculk sensor wool occlusions should block vibration from all sides.
This appears to be fixed as of 22w17a, but I'm not sure when. I suspect 22w14a due to the fixing of MC-207289 - will have to test.

Yes, this is intentional, if you watch the Minecon segment on sculk sensors, you can clearly see that "wool occlusion" exists.
This is not intentional in my mind. I think you might be misunderstanding what I am saying. If you place a wool on certain axis from a lever, sometimes it will detect the sound other times it will not. Watch this video: https://youtu.be/7HN89WI5_SQ
Can confirm.
Hmm, must be something with the wool positioning. Hard to tell if this is intentional or not.

here is another 55 second video with some additional information. as you can see the wool works different on different cardinal directions. but the problem goes a little further, in the end of the video it's showcasing that the wool block even work different on some coordinates. there are certain coordinates with weird behaviors, x=81 z=8 is one of those.
Is this still an issue in snapshot 21w05a or later?
Can confirm in 21w05a that this is still an issue.
Can confirm in 21w05b.
Can confirm in 21w06a.
Can confirm in 21w07a.
Can confirm in 21w11a.
Can confirm in 21w14a.
Can confirm in 21w16a.
Can confirm in 21w17a.
Confused
Can confirm in 1.17.
Can confirm in 1.17.1.
Can confirm in 21w42a.
Can confirm 1.18 pre-5
If you look at this image:
The way of checking for wool is by doing something known as a raycast. It's a line that checks for every block that it intersects. Although when going at a perfect 45 degree angle you run into a problem. A raycast is only able to interact with a single block at any point on the ray.
So the solution around this is simply to check the other block that would not have been hit. We do this by first checking if the ray is at a 45 degree angle, if it is then we check the block at the same position but switch the x & z to get the opposite side.
Working Fix
Can confirm in 1.18.1.
Can confirm in 1.18.2.
I'm still able to reproduce this issue in 22w12a.
