Blocks with special collision behavior have a larger detection range than previously
Blocks with special collision behavior have wider ranges than before in 1.21.1 when standing up against these blocks.
Affected Blocks:
(Comment for any I missed)
- Honey block
- Fire
- Powder snow
- Nether portals
- Cauldrons
- Bubble Columns
- Cobwebs
- Soul Fire
- End Gateways
- Sweet Berries
- Big Dripleaf
Steps to Reproduce:
- Recreate this simple setup:
- Place down any of the affected blocks on top of the red wool
- Stand half against the white concrete, and half against the affected block
Expected Result:
None of the blocks would have their respective behaviors occur and affect the player, as this did not occur in 1.21.1, and the player is not actually inside of the block.
Observed Behavior:
The blocks will output their behaviors onto the player when standing against the concrete and affected block.
This also is not directional, as using an example where the player isn't standing next to a block, but above it, the same issue occurs:

It appears that you’ve encountered MC-275298. That issue has already been resolved and is expected to be fixed in the next regular snapshot.
This is not MC-275298. That issue is remarked as "fixed" and I can confirm.
This also affects:
Cobwebs
Soul Fire
End Gateways
And precisely, these blocks' detection range is 0.00001001192067636 blocks wider than a full block on each side.
Relates to:
MC-93478MC-101556MC-150455MC-215402 MC-217632Can confirm, also affect water columns with soul sand when the player stand next to it.
Edit : it seem to affect the player even if he stands above and to the side, see the attached videos. Minecraft 2024.08.16 - 14.47.10.03.mp4
Minecraft 2024.08.16 - 14.52.12.04.mp4
Can you pin my comment ?
it also affects sweet berries
Affected blocks+:
Campfire
Soul Campfire
Here is a full list of affected blocks:
This issue lies within the method that collects the block positions for collision. Previously entity hitbox was contracted by 10^-7 blocks so that if the entity intersected the block space of an interactable block by a tiny bit it didnt include it in the collision calculation, and since 24w33a the entity hitbox gets infltated instead which causes the issue
Old code:
New code:
Still in 24w34a
>COMETC2021A1
just a little question: how did you calculate that?
Also affects Wither Rose.
