            <title>[MC-3610] Pistons cannot be de/activated individually when stacked on top of each other</title>
                <link>https://bugs.mojang.com/browse/MC-3610</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;Good evening,&lt;/p&gt;

&lt;p&gt;Excuse me for my poor english.&lt;/p&gt;

&lt;p&gt;I experienced an issue with the activation of vertical pistons.&lt;/p&gt;


&lt;p&gt;&lt;a href=&quot;https://mojang.atlassian.net/secure/attachment/13948/2012-11-21_13.37.08.png&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;The first screen&lt;/a&gt; shows us the configuration: 2 piston taking alimentation from stone block near them, and redstone torch to tell us if the stone is alimented.&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;https://mojang.atlassian.net/secure/attachment/13949/2012-11-21_13.37.13.png&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;The second screen&lt;/a&gt; shows us what happens if we alimente the bottom piston only.&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;https://mojang.atlassian.net/secure/attachment/13950/2012-11-21_13.37.20.png&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;The third screen&lt;/a&gt; shows us what happens if we alimente the top piston only.&lt;/p&gt;

&lt;p&gt;At &lt;a href=&quot;https://mojang.atlassian.net/secure/attachment/13951/2012-11-21_13.37.27.png&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;the fourth screen&lt;/a&gt; we alimente both pistons, every thing works well.&lt;/p&gt;

&lt;p&gt;At &lt;a href=&quot;https://mojang.atlassian.net/secure/attachment/13952/2012-11-21_13.37.32.png&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;the fifth screen&lt;/a&gt;, we cancel the bottom piston&apos;s alimentation: here&apos;s the problem.&lt;br/&gt;
The bottom piston is still activated while the bottom redstone torch shows that the stone is not powered: the piston should be deactivated.&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;https://mojang.atlassian.net/secure/attachment/13953/2012-11-21_13.37.39.png&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;The screen six&lt;/a&gt; just shows us that the redstone torchs don&apos;t change anything.&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;https://mojang.atlassian.net/secure/attachment/13954/2012-11-21_13.37.49.png&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;The screen seven&lt;/a&gt; shows that system come back to normal if we take away the power.&lt;/p&gt;

&lt;p&gt;And &lt;a href=&quot;https://mojang.atlassian.net/secure/attachment/13955/2012-11-21_13.38.00.png&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;the last screen&lt;/a&gt; shows the system from his back.&lt;/p&gt;


&lt;p&gt;I had this bug on online server and offline on private world on the last version, and both creative and survival.&lt;br/&gt;
This is really sad, because we can&apos;t deal with the powering of vertical stack of pistons.&lt;/p&gt;

&lt;p&gt;exemple of application: double vertical piston system&lt;/p&gt;


&lt;p&gt;Thanks for reading me, the redstone mechanics is one part of minecraft that I really love.&lt;/p&gt;

&lt;p&gt;I wish you a good week.&lt;/p&gt;</description>

&lt;p&gt;PC crafters can rest easy, too: we aren&#8217;t planning to remove quasi-connectivity from that version. But stay tuned for other exciting developments there, too!&lt;/p&gt;&lt;/blockquote&gt;
&lt;p&gt;&lt;a href=&quot;http://mojang.com/2016/08/whats-happening-with-redstone-on-pocket-win-10/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://mojang.com/2016/08/whats-happening-with-redstone-on-pocket-win-10/&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;Welp, I suppose that&apos;s the final nail in the coffin for people wanting to get it fixed. This report can finally be &quot;resolved as Won&apos;t Fix&quot;.&lt;/p&gt;</comment>
                            <comment id="209481" author="ijatsu" created="Sat, 22 Nov 2014 20:10:54 +0100"  >&lt;p&gt;I tested in 1.8.&lt;br/&gt;
There&apos;s no such ghost behavior now. But it&apos;s still impossible to activate separately pistons stacked vertically.&lt;br/&gt;
And honestly it is a reason I stopped minecraft: you create an object called piston, opening a new world of possibilities. In fact no the possibilities are really limited and the fixes on this was more like &quot;featuring the bug more than fixing it&quot;, this is dirty work.&lt;/p&gt;

&lt;p&gt;You truly can&apos;t do everything you want, there isn&apos;t even a simple featured way to extend the size of the pistons, there isn&apos;t even the feature of catapulting sand and player when turned to the top. Pistons are a shame, if I wonder what was in the head of the devs when they implemented the piston mod i think about this &quot;meh you want it, get it, happy now?&quot;.&lt;/p&gt;

&lt;p&gt;This is sad.&lt;/p&gt;</comment>

                            <comment id="104351" author="pokechu22" created="Thu, 19 Sep 2013 05:44:12 +0200"  >&lt;p&gt;What is &quot;is blocked by&quot; mean?&lt;br/&gt;
Isnt this basicly a duplicate?&lt;/p&gt;</comment>
                            <comment id="23880" author="ijatsu" created="Wed, 21 Nov 2012 17:33:33 +0100"  >&lt;p&gt;Thanks for your answers.&lt;/p&gt;

&lt;p&gt;CubeTheThird: it&apos;s the most na&#239;ve way to power pistons, the problem is that it powers both top and bottom pistons, i use a &quot;proxy&quot; stone block to power only one piston.&lt;/p&gt;

&lt;p&gt;Tails: It works only if we works we 2 pistons, in my case it&apos;s not possible because i have a big vertical stack of pistons and i need to control each separatly. &lt;img class=&quot;emoticon&quot; src=&quot;https://bugs.mojang.com/images/icons/emoticons/sad.png&quot; height=&quot;16&quot; width=&quot;16&quot; align=&quot;absmiddle&quot; alt=&quot;&quot; border=&quot;0&quot;/&gt;&lt;/p&gt;

&lt;p&gt;I believe it&apos;s a bug because it works separatly, but when the top one is activated, if you activate the bottom one he&apos;s stuck in this position, you can barrely remove everything else except the bottom piston, he will keep being stuck. &lt;img class=&quot;emoticon&quot; src=&quot;https://bugs.mojang.com/images/icons/emoticons/sad.png&quot; height=&quot;16&quot; width=&quot;16&quot; align=&quot;absmiddle&quot; alt=&quot;&quot; border=&quot;0&quot;/&gt;&lt;/p&gt;</comment>
                            <comment id="23865" author="bljat" created="Wed, 21 Nov 2012 16:02:46 +0100"  >&lt;p&gt;This is kind of related to the piston quasi connectivity. To be able to control 2 pistons above each other without interference use the setup I provided in the screenshot.&lt;br/&gt;
Edit: Using the &quot;feature&quot; explained here: &lt;a href=&quot;https://bugs.mojang.com/browse/MC-3592&quot; title=&quot;Pistons can be powered by a torch from 2 blocks above. Unrelated to Block Update Detection.&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-3592&quot;&gt;&lt;del&gt;MC-3592&lt;/del&gt;&lt;/a&gt;&lt;/p&gt;</comment>
