| Description |
|
A sticky piston powered as in the picture below will create less than one tick pulses but the piston still holds on to the block. Powering the repeater to the left causes this. What I would expect to happen is the block to be left in the extended position as it does in nearly every other setup with 1 tick or shorter pulses. |

Please check if that's still an issue for you in the latest 1.15.2 stable release or the latest 1.16 development snapshot. |

@Connor Steppie I can reproduce this in 18w47b. |

Is this still an issue in the most recent versions (currently that is 1.10.2, or 16w42a) of Minecraft? If so, please update the affected versions and help us keeping this ticket updated from time to time. If you are the owner/reporter of this ticket, you can modify the affected version(s) yourself. |

To quickly clarify why this bug occurs: To confirm this, you can have a repeater coming from the redstone dust that powers the piston, which updates the piston (without powering it). This is not necessarily a bug, we might eventually see what Mojang thinks of it. If it were fixed, many buds would definitely break, such as the sticky piston with a slimeblock and a redstone block bud, or the one with glass and sand on top. Thus I would prefer to see this report's solution also become 'works as intended'. Generally, redstone changes are bad, because they often break many contraptions that rely on current redstone mechanics. This one certainly would break quite a few if it were Fixed. |

Yes, this still happens in 1.9.1-pre3. Now that the related piston report is 'works as intended' I believe we can agree this is not intended behavior |

Is this still an issue in 1.9 or 1.9.1-pre3? |

Agreed. Which is why |

Invalid? This bug is about more than leaving the block behind or not... The idea here is that in the majority of configurations the pistons will leave blocks behind with a short pulse but in this one it will not. An inconsistency is bad regardless of which outcome was intended. |

Confirmed in 1.8.2-pre6, but see my previous comment as to why this is invalid. |

This is not actually a bug, it's an exception to |

Is this still a concern in the current Minecraft version 1.8.1 Prerelease 3 / Launcher version 1.5.3 or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases. |

In earlier versions, the piston would leave the block behind. This was quite useful as a mono stable circuit that only fires once until it gets reset (pulling the block back in). I had a segmented farm setup that took advantage of this nicely. The piston removes its power source the instant it is powered, so it should create a <1 tick pulse and leave the block behind. "Fixing" it by adding another piston isn't very practical in survival and/or compact setups. |

I just want to point out that this is not a bug to start with. It makes total sense. (And it's useful.) |

Still happens in 14w30c |

Is this still a concern in the latest Minecraft version 14w30c? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases. |

If this is the case, then why does stringing a line of repeaters after the block to the right show a series of 1 on 2 off pulses? Also, the dust is graphically flickering for less than one tick. |

I can explain this. |

To whom and how do I ask? |
| Comment by Tails [ 06/Mar/13 ] |

Only Mojang knows. |
| Comment by João Mambelli [ 06/Mar/13 ] |
|
Tails, can you explain? |
| Comment by João Mambelli [ 06/Mar/13 ] |

Also wanted to know why when you place a sticky piston, a boco in front and a torch on top of the block, the piston pushes and pulls back the block. This was to be a pulse of 1 tick. |

Confirmed. |
