            <title>[MC-1307] Corner stairs have a gap in the hitbox</title>
                <link>https://bugs.mojang.com/browse/MC-1307</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;When stairs are placed in a Z-shape with 2 corner stairs next to each other, placing blocks on/next to the corner stairs behaves inconsistently.&lt;/p&gt;

&lt;p&gt;It&apos;s hard to explain in words - just look at the pictures.&lt;/p&gt;</description>

confirmed for 15w34d&lt;br/&gt;
can the title be changed so it is more clear what the issue is?&lt;/p&gt;</comment>

                            <comment id="65076" author="bugi74" created="Sat, 4 May 2013 21:17:34 +0200"  >&lt;p&gt;(Adapting part of my comment from &lt;a href=&quot;https://bugs.mojang.com/browse/MC-15132&quot; title=&quot;Can not place on back face of stairs. &quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-15132&quot;&gt;&lt;del&gt;MC-15132&lt;/del&gt;&lt;/a&gt; to here; note, this issue affects more than just placing other stair blocks: )&lt;/p&gt;

&lt;p&gt;The crosshair (aiming) raytracing is done with the &quot;real&quot; stairs, not the visuals of the stairs. The aimed stairs block can be placed in two orientations which both produce the same visual result.&lt;/p&gt;

&lt;p&gt;Screenshot &apos;stairs_orientations.png&apos; shows the two orientations: the upper placement (after adding a stairs block to the corner) shows the issue, while the lower placement will not.&lt;/p&gt;

&lt;p&gt;First I thought this is a minor bug, but then I realized that this can be used to shoot arrows through a visually solid stairs (near the corner). I think the real bug here is that the stair&apos;s raytracer method uses only the block&apos;s data to figure the shape of the block, instead of the visual shape based also on the neighbor blocks&apos; data. As the raytracer is used for multiple things, it might be good to improve it; doing that would automatically fix all the use cases at once.&lt;/p&gt;</comment>

This does indeed only happen with stairs though.&lt;/p&gt;</comment>
