I created a staircase with a roof of upside down stairs above it. The top stairs were positioned such that if the player were to stand inside the staircase, they would fit, but couldn't enter the staircase under normal circumstances. If, however, the player moves in just the right way, they can make it partway up the staircase, but will then be stuck (keep in mind that the player initially wasn't able to enter the staircase). Furthermore, sprinting up the stairs causes the player to be able to make it to the top and exit completely, but unable to go back down the stairs, even while attempting to sprint.
I suspect this has to do with MCPE-30039, as the data presented from the report indicates that the coordinates are being rounded DOWN, allowing the player to run up the stairs without hitting their head on the upside down stairs above them. This hypothesis also explains why attempting to go down the stairs doesn't work, as rounding down in this case results in the player's feet clipping through the floor (since the player's coordinates are measured from the lower half of the player model on Minecraft Bedrock).
Steps to Reproduce
build a staircase using stair blocks (note: might be directional)
build a roof above the staircase, again using stairs, but upside down this time) such that there is a 2 block gap between stairs that occupy the same x and z coords.
sprint up the stairs
attempt to sprint back down
Expected results: the stair tunnel would not be traversible, as the players hitbox is 0.6 blocks in width, causing the upside down stair that is located 2 blocks above and one block in front of the stair you are attempting to climb to block your movement.
Observed results: you can sprint up the stairs just fine, but you cannot go back down.

Hi. Sorry for not getting back. I havent been able to test this in the latest version due to not having a lot of free time. I remember seeing it happen a bit more recently, but i will try to test it in the newest version. As for the steps to reproduce, here they are:
1)build a staircase using stair blocks (note: might be directional)
2) build a roof above the staircase, again using stairs, but upside down this time) such that there is a 2 block gap between stairs that occupy the same x and z coords.
3) sprint up the stairs
4) attempt to sprint back down
Expected results: the stair tunnel would not be traversible, as the players hitbox is 0.6 blocks in width, causing the upside down stair that is located 2 blocks above and one block in front of the stair you are attempting to climb to block your movement.
Observed results: you can sprint up the stairs just fine, but you cannot go back down.
Still an issue in 1.21.60.24 Preview. I have added slightly better steps. I am also requesting ownership of this report as the original reporter has not been active since April 2022.
Improved Reproduction Steps:
Build this structure. This structure consists of only wooden blocks and a diamond block. There are no hidden blocks. This structure can be any direction.Â
[media]Sprint or walk up the stairs (but do not sneak). Get to the topmost part of the top stair. Careful not to fall down the last stair.
Attempt to get back down the stairs without falling off the staircase or using sneak.
Thank you for your report!
However, this issue has been temporarily resolved as Awaiting Response
Is this still an issue in the latest version?
