Sneaking on ice can change direction of movement to lines along axis

It is possible to move on ice blocks while crouching, in a direction up to 45 degrees away from the direction you should be moving based on the movement key you are pressing.

 

How to replicate: (this is shown in the video "Ice Sneaking Direction Glitch Take 3")

  1. Build a flat surface of ice blocks. Stand in the centre, and face diagonally on the X/Z axis.

  2. Move your crosshair to be just to the side of the exact diagonal between the X and Z axis (it doesn't matter which side). Your crosshair should not move from this point onwards.

  3. Wiggle your player left and right, alternating directions a few times each second.

  4. While still wiggling, crouch.

If the glitch has happened, you will notice your direction of movement has changed. You can stop wiggling, but stay crouched. Now if you attempt to sneak left or right, you should notice that your character moves straight along either the Z or X axis. This can be made easier to see by doing either (or both) of the following;

  • Switch to third person view. You should see your character's body (most noticeably their arms) shudders while you move during the glitch.

  • Build a flat surface of non-ice blocks connected to your ice surface, at the same level. Once you have begun the glitch, if you sneak off the ice and onto the non-ice blocks, you will notice your direction of movement changes back to what it should be.

Whoops, I resolved the wrong ticket by accident. Disregard fix version 19w35a.

Can you provide a short video of you reproducing the issue? From your description I was unable to reproduce.

Lewis Elliott

Done.

As you can see, when I sneak along, pressing only a or d, I go parallel to the blocks rather than diagonally. Then when I step onto the netherack, my direction changes to what it should be and I start moving diagonally.

Is this still an issue in 1.16.4?

Lewis Elliott

Yes, and I found an easier way to replicate it. I'll attach a new video later today.

Thank you! I finally got it to happen! Feel free to update the description if you want

Lewis Elliott

Done! This was fun 🙂

Confirm for 22w14a
This is actually a by-product of MC-241951
I have tested it already, and my fix for MC-241951 fixes this bug also.

Affects 24w21b
The information by @unknown is still noteworthy though (could simply duplicate that issue, or have a 'caused by' relation added if the issue should stay seperate).
