            <title>[MC-1669] Possible to walk through two perpendicular anvils at the corner where they meet.</title>
                <link>https://bugs.mojang.com/browse/MC-1669</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;Only tested in SMP.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;What I expected to happen was...:&lt;/b&gt;&lt;br/&gt;
Running against an anvil (actually to jump on it &lt;img class=&quot;emoticon&quot; src=&quot;https://bugs.mojang.com/images/icons/emoticons/biggrin.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;&lt;b&gt;What actually happened was...:&lt;/b&gt;&lt;br/&gt;
I was pushed back and forward while running forward.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;Steps to Reproduce:&lt;/b&gt;&lt;br/&gt;
1. Place an anvil (in front of a wall)&lt;br/&gt;
2. run against it.&lt;br/&gt;
3. Be pushed back. (Looks laggy and a bit like suffocating in the anvil).&lt;/p&gt;

&lt;p&gt;Explanation of the bug in this video: &lt;a href=&quot;http://www.youtube.com/watch?v=y1kon5Wax8I&amp;amp;feature=youtu.be&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://www.youtube.com/watch?v=y1kon5Wax8I&amp;amp;feature=youtu.be&lt;/a&gt;&lt;/p&gt;</description>

                            <comment id="145794" author="zoshi235" created="Sun, 9 Mar 2014 03:47:25 +0100"  >&lt;p&gt;The four screenshots I originally posted are invalid. The real cause is looking at an anvil facing the other direction, not turning. The hitboxes of all anvils is set to the last one you looked at. The same thing happens with double chests, but the difference isn&apos;t big enough to let you pass through completely, which if I&apos;m not mistaken, makes this issue a duplicate.&lt;/p&gt;</comment>

Confirmed in 1.6.2 both with anvil and a chest.&lt;/p&gt;</comment>
                            <comment id="98680" author="zepheros" created="Tue, 13 Aug 2013 19:29:26 +0200"  >&lt;p&gt;This needs to be updated for 1.6.2 as it is still an issue.&lt;/p&gt;</comment>
                            <comment id="79052" author="domas321" created="Sun, 30 Jun 2013 16:16:30 +0200"  >&lt;p&gt;I think this is caused by unsynced width of anvil block in singleplayer and server files. Thus, playing in SP is ok, but server thinks that anvil is wider than client knows, pushing player back when updating his position. So the fix would probably be changing anvil&apos;s hitbox in server files.&lt;/p&gt;</comment>

A quick search through the issue tracker revealed my worst fears: Anvils can be decorporealized at will. I have uploaded a series of four images describing the process.&lt;/p&gt;</comment>

So you can&apos;t pass by it walking against the long sides of them.&lt;/p&gt;</comment>

Comfirmed.&lt;/p&gt;</comment>
                            <comment id="17975" author="ryuutei" created="Sun, 4 Nov 2012 12:56:49 +0100"  >&lt;p&gt;Same thing happens for me on my Linux server with an OSX and Windows client. (1.4.3 Pre-release)&lt;/p&gt;</comment>
                            <comment id="17805" author="tigerfly" created="Sat, 3 Nov 2012 22:23:40 +0100"  >&lt;p&gt;Tested in Multiplayer there (1.4.3 pre-release)&lt;/p&gt;

&lt;p&gt;Bug comfirmed : collision bug when running into the anvil (little knockback)&lt;br/&gt;
                collision bug when : force walking into the anvil, then moving left or right -&amp;gt; being stuck with a spazzing knock back until we stop moving in that direction&lt;/p&gt;

&lt;p&gt;Solo mode : seems to have no bug with collision.&lt;/p&gt;</comment>
