            <title>[MC-11242] When you jump and place a fence post under you you will get inside the fence post</title>
                <link>https://bugs.mojang.com/browse/MC-11242</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;h3&gt;&lt;a name=&quot;Thebug&quot;&gt;&lt;/a&gt;The bug&lt;/h3&gt;
&lt;p&gt;When you jump and place a fence post under you you will get inside off the fence post.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;Note:&lt;/b&gt; This works correctly for fence gates and cobblestone walls.&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 class &lt;tt&gt;BlockFence&lt;/tt&gt; is not overriding the method &lt;tt&gt;net.minecraft.block.Block.getCollisionBoundingBox(IBlockState, IBlockAccess, BlockPos)&lt;/tt&gt; and therefore returns the hitbox instead of the collision box.&lt;/p&gt;</description>

The fact that you can fall though it is intended, you are inside the fence&apos;s hitbox, and that is how crouching works. The actual bug is that you can place the fence there in the first place. The game should detect that the block would intersect your hitbox and should prevent the placement like it does with other blocks.&lt;/p&gt;</comment>
                            <comment id="204174" author="conormcs" created="Sat, 18 Oct 2014 20:17:59 +0200"  >&lt;p&gt;Confirmed for 1.8.1-pre2.&lt;/p&gt;

&lt;p&gt;Suggested fix for the devs:&lt;br/&gt;
Replace the 1.5 block high collision box of the fence with a 1 block high one that matches the visual shape, and then add an invisible 0.5 block high collision box on top. This will not be a perfect solution, it just means that if a player manages to fall through the top 0.5 block section, they will be standing on what is effectively a 1 block high internal support platform. Due to the fact that the fence is only visually 1 block high anyway, this would mean a player wouldn&apos;t even appear to be inside the fence.&lt;/p&gt;</comment>

&lt;em&gt;Ouch. That looks like it hurt. (Sic!)&lt;/em&gt;&lt;/p&gt;</comment>
