Piston arm animation is inconsistent and choppy

I would not say that the second video shows a "smooth" animation. It's a little less choppy than the first, but it's not smooth at all compared to Java.

I clipped the first two extensions and retractions of each video and slowed them down twice using Windows default tools. Here they are for comparison:

Looking more closely at these examples I observe the following:

• The extension and retraction animations at best run in exactly 4 steps. Since an extension takes 2 game ticks or 1/10th of a second, that means the piston extension animation is capped at 40 fps. Not terrible, but not great either. (The 4 steps are not an artifact of my video recording or editing in Windows. I also observed exactly 4 steps examining

• , which I made in Minecraft on my iPhone 8, and I have noted 4 steps in supporting media from other reports.)

• The 4 steps are not consistent with each other. This is why even the "smooth" animation (which I called "Not choppy..." in the video name) is actually not very smooth. In the first extension from the smoother video, the animation steps jump as follows:
  ||Animation Step||Step Distance (pixels)||Total Distance (pixels)|| ||
  |1|3.5|3.5|

  |2|4.5|8|

  |
  |3|6.25|14.25|

  [media]

  |
  |4|1.75|16|

• Sometimes (randomly) the animations appear to only have two or three steps. This largely accounts for the less smooth/"Not choppy..." video examples. Given the inconsistency noted in the previous point, this point may just be a result of the game playing successive steps with no difference in distance. Note that the second extension in the smoother/"Not choppy..." video, there are four steps, but the total distance goes 8, 15.5, 15.75, 16.

This report is about the piston arm animation, not blocks moved by the piston. MCPE-146597 refers to the moving block. They are separate issues as the piston arm animation has been the same choppy and inconsistent through many different versions while moving block visuals have changed.

MCPE-146597 talks about the block that is being moved by the piston, while this one is about the piston arm itself not being smooth, which an entirely separate issue.

The ticket has been slightly updated to clarify what the issue is about.

It seems the beta did not fix this issue

This is not fixed in the latest release.

I have downloaded the latest release; It's hard for me to tell, but it appears to be slightly improved.

Block movement animation has yet to see any kind of treatment, but that's a different issue with its own ticket.

FireLiz, if you can provide some footage to demonstrate whether the problem still consists, that would be appreciated.

This is not fixed in the latest release. I have attached a video.
 
 

By the look of it, the problem seems to remain persistent. Therefore, the issue has not been solved yet, and this ticket should be reopened.

We're always told to use this site as a platform to report bugs. And now we're being told otherwise for doing this exact same thing. This is ridiculous.

Sorry for the delay in reopening the report.

Thanks for reopening

apparently, the issue has been marked as "fixed" in the latest preview versions. If someone could upload a short video demonstrating it, it would be appreciated.
