[MCPE-109925] Player hitbox incorrect after hitting a wall with an elytra

You will be able to go through blocks above you after hitting a wall while flying with the elytra.

Steps to replicate

Equip elytra
Fly into a block, preferably a wall you built that should be easy to fly into, but a tree also works (do this in survival)
You are no longer flying after hitting that wall (make sure to not glide again)
Walk into a space with a roof 2 blocks off the ground
Jump
You can go into the block above you
From here you can test it further by going into one block gaps and other places. It is very easy to suffocate by jumping when inside 1 block gaps, but you will probably suffocate just from walking into them.

Ways to reset yourself after going into this mode

Reload the world, your hitbox will be normal
Use the elytra again and not hit a wall. This is probably the easiest and simplest way
There might be a way by doing something while swimming, but I am not sure

After further testing

There is a way to fix it while swimming, but it is not because you are swimming that it fixes itself. You can "glide" while swimming, which activates the same fix as if you would on land. It has the same effect that fixes your hitbox, but you will not start to actually glide like you would in lava or land. You just need to press space while swimming, sometimes multiple times. It is somewhat related to MCPE-54255, since doing that bug fixes the effects of this one.

As stated in the comments, dying while swimming in a 1 block gap will also have the same hitbox bug. The same effect will not happen if you die while swimming with water above you, ~~so I think that there is either a certain timing between damage and switching hitboxes that activates it, or it is caused by being forced to switch hitboxes in a specific way by damage.~~ It is not damage, since I was able to get this bug in creative. I think it might just be caused by switching hitboxes in a specific way, regardless of damage.

Confirmed for 1.16.210.50

Andrei the Ghost 2020-12-09T20:39:21Z

Hi,

My issue

MCPE-109537 is exactly the same. At least i wasn't able to explain it jet.

Skaijie 2020-12-11T15:53:51Z

I think the root issue can be phrased generally as "taking damage and attempting to switch to another hitbox in the same tick locks the hitbox".
Comment from duplicate MCPE-110647 indicates that this also happens when dying while swimming.

Hipposgrumm 2020-12-11T15:56:38Z

Swimming will fix because swimming changes the hitbox size.

osfanbuff63 2020-12-22T13:31:06Z

I have experienced this bug but I think that incorrect hitboxes happens with another, similar bug. My reasoning is that I had other people in my world who had never even equipped an elytra, much less run into a wall with one, and were still experiencing the bug! They have also not died while swimming in a one block high space.

Anyone have any thoughts on what else could be causing these incorrect hitboxes? It would be much appreciated!

If a player dies while in a swimming state, this will also occur once they respawn.

Jonathan5733 2021-01-02T22:07:26Z

Could this possibly be related to MCPE-85052?

osfanbuff63 2021-01-04T00:09:14Z

@Jonathan Hanzel I think it could be

Hacker1MC 2021-01-04T14:05:53Z

@Jonathan Handel I don’t think it would be by an important amount, that one is relating to the player’s camera, where this one is about the hitbox for walking. They both do involve using the elytra to get a smaller hotbox, but no other similarities from there.

jamie craft 2021-01-09T10:13:40Z

I have also been experiencing similar issues, and not purely from elytra flying or swimming. The frequency has been increased by elytra usage, but it did occur before and I cannot recall any times when I or others respawned after dying while in a swimming state. From this, I can only assume it has multiple causes as well as the elytra and swimming ones. I hope this helps 🙂

Yiannis Siakaris 2021-01-10T10:34:08Z

I experience this bug a lot and I got so used to it that i exploit it by going in 1 block high places (it is painfull though). I also came to the conclusion that if you reactivate your elytra or leave the chunk youre in when this happens the bug goes away most of the times. I belive bug is the reverce of MCPE-31896 , were the hitbox doesnt change when flying or swimming to the corect 1 block high hitbox. Instead it changes after you stop swimming and flying and under conditions like coliding with walls.

Azarel Howard 2021-01-14T09:42:34Z

I am able to replicate this issue in an offline creative world (while wearing elytra) as well as on a private Bedrock server. Issue is pervasive and effects all players on our server. Including when in our tunnels where flying isn't possible.

I'll find/create a bug report for this as well but tangentially we're noticing that when we go through our nether portals it's possible to come out inside the obsidian. Thankfully you usually only take a couple of hits of suffocation damage before the server figures out it screwed up and shifts you over a block but... it happens pretty regularly and might be related.

Edit: Found the related ticket if you're reading this and have this issue go here MCPE-28765 turns out this issue occurs more frequently going from the overworld to nether. There is a workaround in this instance. However for nether to overworld, the issue I'm encountering, no known workaround exists currently.

Note that I mention this issue because being able to phase through blocks occurs in conjunction with this issue on our server, some of the time. It's not 100% correlated but it happens often enough to be worth mentioning.

Phoenix TF 2021-01-18T13:40:57Z

I did it without the use of an elytra once.

kmb600 2021-01-22T21:56:54Z

affects 1.17.30.20

Eduardo Mejia 2021-01-24T23:13:53Z

I make a similar issue, but without hit a wall.
When i try to fly but can´t get and return to ground, the player hitbox don't work correctly. Exactly like your videos. (I have a beacon with jump boost 1)

Kaustub /Dattkaya 2021-02-07T20:47:28Z

I have done a lot of research and found this has to do with your hit box changing the frame you move your hit box ( enderpearls) or/and being inside a block when your hit box returns to normal from gliding to riptiding. if you update your hit box in any way it is canceled. for example having the space bar pushed down while moving down updates, swimming updates, riptide, reloading, gliding, and pearling. suffocating usually doesn't happen but it probably a 50/50 thing. I would say ask for footage from victims of the glitch to identify more causes for this.

Joshua Green 2021-02-09T15:51:38Z

I have done further research on this issue, and I have found that almost any time that the player is pushed into a block(pistons, standing on shulkers, gravity blocks) will activate this bug. I have noticed that it somewhat halves your hitbox to about 1 meter tall, but the suffocation box is still at the correct place.

Apig0123456 2021-02-23T19:23:00Z

I can simply walk into the block, no elytra or anything needed.

Ahoop 2021-02-23T20:45:36Z

I can do the same thing Zayne! I reported this issue separately and someone merged it here, I don’t even know if they are related.

Jason Petersen 2021-03-04T02:02:25Z

It would be much easier to read the activity and related pane were there a separate "Duplicate" label rather than "RESOLVED". Yes, I know their status is duplicate, but I have to click through to see that, and seeing a ton of "RESOLVED" things up top gave me false hope.

I run a Bedrock server with people playing from iOS, Windows (10, mostly), PS4, and Switch and every one of us has experienced this bug.

I realize the upcoming release is important, but we're getting annoyed enough at suffocating in our own houses that I'm not sure we'll make it that long.

From our experience, this is an incredibly easy bug to reproduce. No, I don't know what causes it, but as it happens every time we play, if I had a debugger (maybe not even source!) I hope I could knock this out in a week, tops. It goes away after dropping and reconnecting, and it's some state related to the player, be that client or server side, but it feels like comparing the differences between those states and starting from there could get somewhere.

Carlo Lovejoy 2021-03-11T02:43:04Z

Man I didn't have this issue till the new update... This is ridiculous! Extremely annoying when I try playing in my survival realm. I'm in the end right now stuck with shulkers keep hitting me causing me to constantly being pinned inside the ceiling.

Tracy Colletta 2021-03-15T14:02:54Z

Same for me. After updating to 1.16.2310, I went End-busting and have been dealing with phasing through blocks constantly when hit by shulker bullets. Soooooo frustrating.

Michele 2021-03-16T16:09:13Z

This issue has become much worse after the realms update. Especially in the end! I've died multiple times in the last few days because I'm hit by shulkers and levitate into blocks. So frustrating.

Gavin Gibbs 2021-03-17T20:37:50Z

This bug has gotten worse since the recent update. Used too, if you took off the elytra and then put it back on the issue would resolve itself. Now when you take the elytra off, the bug acts the same whether the elytra is on or off.

Travis Hauser 2021-03-23T23:55:58Z

This also seems to occur for me when using scaffolding. I’ve been having this issue even when my elytra isn’t equipped. After observation the only other thing I’m doing that’s unusual is building and climbing scaffolding in tight spaces

osfanbuff63 2021-03-24T11:25:52Z

According to a duplicate report, this can cause xray.

Jonathan5733 2021-03-24T20:15:09Z

osfanjoshua There is a report on another Elytra X-Ray glitch that is being tracked at MCPE-85052

osfanbuff63 2021-03-24T21:08:59Z

Jonathan Hanzel That bug is slightly different from the one I mentioned.

Jonathan5733 2021-03-24T22:07:33Z

osfanjoshua I am aware of that. I'm just trying to make sure you know that they are different (note: the updated version of the comment says "Another Elytra X-Ray glitch"), however the two X-ray issues may be related (I will check with that on the other tickets)

Jonathan5733 2021-04-07T07:28:05Z

I just discovered that you can use MCPE-85052's test world to try and test this bug (MCPE-109925), I'll provide a screenshot of the layout of MCPE-85052's test world if requested by a mod. To use the MCPE-85052 test world:

Download the test world from MCPE-85052 (I'll attach it to this report if asked to by a mod)
You will spawn with an elytra already equipped on a small platform enclosed in dirt blocks
There should be a "landing point", and a wall of dirt at the end
Crash into the wall at the end (you can try the side walls, but it's probably too hard)
Break one of the blocks of dirt on the bottom of any of the walls (it won't drop)
Walk through the wall where the block of dirt was broken

I discovered you can do this while trying to reproduce MCPE-85052 in 1.16.220, and reproduced both issues (MCPE-109925 and MCPE-85052) in the same world within the same few seconds.

Zephyr Tolliver 2021-04-12T17:04:30Z

I can confirm that this is still a problem in 1.16.220, how to recreate:

fly into a wall (in survival mode) so that your elytra disengages,
then, walk into a block floating 1 block off of the ground,
and you will find that your head glitches through the top block,

you will find this also works with any blocks off of the ground including 2 block high ceilings that you jump into. Developers, please fix this, it has been in the game for the last three updates.

Draco894 2021-05-16T03:34:26Z

This happens without Elytra as well so this is not related to players glitching into crawl mode with Elytra.

osfanbuff63 2021-05-18T18:55:48Z

@unknown It is related to that, since that is a reproduceable way to cause the bug. However, it can happen without an elytra.

SrAlliphe 2021-06-08T21:39:01Z

Still happens in 1.17 update - Windows 10 Edition

Vaughn Thomas 2021-06-12T21:38:14Z

Mine is different I have it when I walk through a 1 block space and I go through the bottom on my xbox!

Also I cannot send any screen shots sorry.

Timothy Fox 2021-06-25T05:04:09Z

I have maybe noticed this happen more often after 1.17.2 hotfix. I don't have to be using elytra. I can be walking normally and walk into a 1x1 space at my feet- at which point I begin taking suffocation damage. If the 1x1 space is at head height, my character collides with the block at my feet normally. Reloging doesn't always fix the issue. This is especially difficult while end raiding. After being hit with a shulker bullet, I can float into blocks above my head and begin suffocating. I can break the block above my head and not die, but it seems that the lower half of my hitbox will catch on a neighboring block and I hang there until the shulker effect to wear off.

Beau Farley 2021-07-03T02:57:16Z

This issue needs to be fixed asap. When in the end cities, shulkers will hit you and you levitate into the blocks, unable to move or get away, as they keep hitting you. You're stuck there indefinitely. FIX THIS MOJANG! THIS HAS BEEN HERE SINCE 1.16 RELEASED!!

Hullu Hapua 2021-07-06T17:39:11Z

Actually, it can happen anyway, anytime (but not always) after using elytra. And can be fixed by using Elytra again, or by swimming (sprinting in water). It can sometimes even fix itself.

Branko Šaškovič 2021-07-12T06:29:57Z

Can Confirm in 1.17.20.21

Ryan Ewing 2021-08-20T07:02:33Z

I do have a duplicate post. It was about how that happened. For swimming underwater, spamming the jump button while having the Elytra equipped may end you up having your hitbox to 2 blocks high. I witnessed a different step. In creative, I fly up, then used the Elytra, dived, and I quickly unequip it. That'll randomly get the hitbox to 1 block height.

Yes, it is linked.

Joel Whitney 2021-10-31T22:43:16Z

You can deactivate the bug by using the elytra again

thebigsmileXD 2021-12-29T15:45:39Z

The fix causes unintended side effects on servers when only height or only width are resent (causing the same bug to affect every server out there now)
