| Description |
|
When a piston is powered with a 0 redstone tick pulse (or a half redstone tick pulse, meaning it's powered for only 1 game tick but not a full redstone tick), it only gives a pulse at some occasions, as it can be seen in the screenshots. To reproduce: |

This bug is not due to pistons. Tho its hard to test without them So the X-piston checks for power and fires Then Z-piston checks for power (sees no power due to the block being moved) and doesn't do anything If the block update order was changed from XYZ to XZY or YXZ there would be way less Directional stuff |

Mojang seems to have decided that the purpose of pistons is to have as many inconsistent behaviors as possible. I don't think any piston-related reports are going to be fixed any time soon. |

please fix this. it breaks more redstone contraptions than it fixes |

Leaving the bug like that will also have something broken. |

Maybe fixing that would break something |

I'm sorry, but this bug being flagged as "Works as intended" will leave pistons buggy, as they've always been. Sincerely, it feels like this bug wasn't even read by Mojang before being flagged by that. |

An easy way to explain this is using 'microticks'. |

Sand generators were already fixed. |

Added more screenshots, updated the affected versions and changed the title as well as the description, explaining better what happens. |

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. |

It seems that the pulse is actually 0.5 tick. |

Seems like piston monostable circuit's output is shorter than 1 tick and pistons not responding it. |

This is really weird because with some specific setup, pistons respond. See http://youtu.be/J12aW0hmT98 |

Confirmed. |
