[MCPE-62777] Falling block won't turn into an item with pistons

When sand falls onto a slab, it will normally turn into an item. However, when you put a piston below the slab, sand just falls on the slab, piling together.

Then, if you push the sand, it expands.

If you block the way, sand will not expand, but if you stand on the sand, you will be pushed far away as if the sand has expanded.(Like the stairs with a piston in the picture below)

Someone even built an ultra-fast transportation system with it!

However, it randomly crashes the game.

(Other blocks like gravel acts the same)

This is definitely intended behaviour and a really cool feature.

I agree with 77Tigers. It is a very useful mechanic, such as in this mob farm by NavyNexus. Java Edition has quasi-connectivity and zero-ticking, while Bedrock Edition has sand pushers and trident killers.

This is definitely NOT intended behavior.

Sometimes activating a lot of pistons at the same time also crashes the client(server works fine). Maybe the crash has something to do with the ticking mechanism.

Another strange behavior is that if you use the sand-piston based fast-transportation machine in a server, the user's game won't crash,but if you watch closely or stay within a few chunks to the machine,chances are that your game will crash.

To be fair, this generally is a benign bug. I have experimented with them, and generally it seems they only crash if overloaded (too much sand/gravel). I personally don't see it as much of a priority to fix or too much a problem.

There are no problems in my server though and my offline worlds in Bedrock Edition (especially in my phone) when me or my friends are using this. This is a helpful feature, and one of the unique features to differentiate our mechanics from the Java version. You can use a lot of possibilities to use this kind of mechanic, why fix this? After all, this isn't some sort of OP mechanism that doesn't give any advantage to the player or in a server.

Enzo He 2020-02-10T09:37:04Z

Tested it on server with friends. The player using it did not appear to encounter any problem, but there was a high probability that an observing player's game might crash. A very useful glitch, to be sure, and I wouldn't want it fixed either if not for the crashing issue.

This bug is fixed in the latest beta version, and the fix will be included in a future update when that is ready for full release (no specific date can be given). We will leave this ticket open as a point of reference until the fix has been fully released.

Tested multiple times and never experienced an issue Instead of taking this away you should just let the java players have it too I’m tired of including these mechanics into my farms just to have them taken away it’s making me slowly but surely stop playing all together

Landry Foster 2020-03-07T23:42:23Z

And if this is definitely NOT intended behavior you’re about to lose you’re helping job when bedrock inevitably goes under @LateLag if you actually played the game and listened to the people who spend hours designing farms to help make bedrock edition playable (77tigers naveynax old guy yodolf)you would understand but instead you java favoriting bedrock devs are going to yank something WITH 0 UPVOTES you guys are going to loose anybody who actually plays bedrock hope you’re happy finding a new job

Landry Foster 2020-03-07T23:50:08Z

And the last thing I have to say before I go and cool off is a tip for the reporter of this issue. How about instead of listing this “bug” numerous times (only activity this person has just so happens to be on this issue and nothing else) how about ya just don’t do it? Kinda feels like this is a java player crying to me so that explains why it’s getting patched with no upvotes. This bedrock player is about done with this Blatant favoritism

Hi Landry,

Please be respectful when posting in the JIRA, while this may have been helpful for you there is more to this bug than just the usefulness in some farms.

This mechanic crashes some devices and has been used to ruin the experience for players. While I agree that any loss of functionality can be frustrating there's usually reasoning behind it that we don't get to see. Its also important to note that everyone here are volunteers (sans anyone listed as "Minecraft" or "Mojang". We're just here to help keep the bug report system running smoothly.

I appreciate the reminder and the polite explanation. I apologize for my frustration and thank you for your time.
