            <title>[MC-9194] A Comparator can lock a Repeater, but the Repeater doesn&apos;t look like it is locked</title>
                <link>https://bugs.mojang.com/browse/MC-9194</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;h3&gt;&lt;a name=&quot;Update&quot;&gt;&lt;/a&gt;Update&lt;/h3&gt;
&lt;p&gt;As of the 1.13 snapshots, the repeater will appear locked &lt;b&gt;until the other side is updated&lt;/b&gt;. See the newly attached screenshot &amp;#8211; the repeater appeared locked until the packed ice was placed. Removing the ice leaves the repeater visually unlocked.&lt;/p&gt;

&lt;h3&gt;&lt;a name=&quot;Thebug&quot;&gt;&lt;/a&gt;The bug&lt;/h3&gt;
&lt;p&gt;When powering a repeater from the side by a comparator it can lock the repeater (similar to repeater locking with repeaters). But it doesn&apos;t show the texture of a locked repeater.&lt;/p&gt;

&lt;p&gt;The problem is actually with the comparator, not the repeater. Until you toggle the comparator, it won&apos;t recognize that it is supposed to be locking the repeater. If you place a comparator, then toggle it, then place the repeater, it will already appear locked. The comparator also has to be powered for the toggle to work.&lt;/p&gt;

&lt;h3&gt;&lt;a name=&quot;Codeanalysis&quot;&gt;&lt;/a&gt;Code analysis&lt;/h3&gt;
&lt;p&gt;Based on 1.11.2 decompiled using MCP 9.35 rc1&lt;/p&gt;

&lt;p&gt;The problem is that the power level of a comparator is determined by the comparator tile entity client side as well, but this tile entity is not updated unless the player right clicks the comparator.&lt;br/&gt;
This can cause the opposite of the bug described here as well when the tile entity was updated and stores client side a power level, but the power source was removed afterwards. Replacing it then with the &lt;tt&gt;powered=true&lt;/tt&gt; state (without actually powering it) causes it to display the repeater as locked while it is not actually locked server-side.&lt;/p&gt;</description>

The bug is visual only, repeaters are locking when locked by a comparator, and the visual bug can be temporarily fixed by switching the mode on the attached comparator.  Screenshot of test added.&lt;br/&gt;
Client 14w10c&lt;/p&gt;

&lt;p&gt;Mechanics should be functional for map makers, assuming players will not need to see the repeaters.&lt;/p&gt;</comment>

&lt;p&gt;EDIT:&lt;br/&gt;
Tested it again,  @Kwin van der Veen is completely right. Toggling the comparators torch temporary fixes the bug, reloading chunks/world resets it to its buggy behavior.&lt;/p&gt;</comment>
                            <comment id="87537" author="unleashed75" created="Wed, 10 Jul 2013 01:36:58 +0200"  >&lt;p&gt;its about time this gets fixed seeing them have know about it for so long. how are you meant to make problem solving maps when people cant see the problem that needs to be solved! turns a problem solving map into a lucky guess map!&lt;/p&gt;</comment>
                            <comment id="46319" author="fibonatic" created="Sun, 17 Feb 2013 23:10:06 +0100"  >&lt;p&gt;I just noticed something, if you right click the comparator while being powered (so it would toggle between compare and subtract mode) then the repeater does show that it is locked. Tested this in snapshot 13w06a. However if I reload the world/chunk will reset this and no block update seems the trigger this as well. &lt;/p&gt;</comment>

                            <comment id="44330" author="onyxdarkknight" created="Thu, 7 Feb 2013 22:19:48 +0100"  >&lt;p&gt;I think it was intended because they said they wanted only repeaters to be able to lock other repeaters. So it might actually work as intended. Maybe they weren&apos;t supposed to be blocked that&apos;s why the lock texture doesn&apos;t show, or it should lock it and the texture doesn&apos;t show. Anyway, it&apos;s up to Dinnerbone to decide.&lt;/p&gt;</comment>
