            <title>[MCPE-934] Mobs will not move through stationary water blocks (id 9)</title>
                <link>https://bugs.mojang.com/browse/MCPE-934</link>
                <project id="10200" key="MCPE">Minecraft (Bedrock codebase)</project>
                    <description>&lt;p&gt;There was a zombie in my pool, I expected it to chase after me. It didn&apos;t, it just continued to swim around. I even got closer, it only hurt me when I pushed into it. (Sorry if this is a duplicate, I searched for similar problems but didn&apos;t find anything). In the picture it looks like it is looking at me, but this was the screen shot I was able to get whilst staying above water.&lt;/p&gt;</description>

                            <comment id="35957" author="cultist_o" created="Sat, 12 Jan 2013 09:48:50 +0100"  >&lt;p&gt;The same seems to be true with fire proof mobs in deep lava&lt;/p&gt;

&lt;p&gt;I mentioned this on an issue that was marked a duplicate of this, so I thought I would mention it here&lt;/p&gt;</comment>
                            <comment id="26164" author="do" created="Sun, 2 Dec 2012 03:54:02 +0100"  >&lt;p&gt;Hmm, so the description I gave above is a little inaccurate... it ultimately doesn&apos;t matter what kind of water you place, since at some point (after saving and reloading, or block updates?) they&apos;ll become the same blocks either way... block 8 around the edges and 9 in the center, as far as I can tell. There&apos;s definitely a problem with the mobs swimming through block 9, though.&lt;/p&gt;</comment>
                            <comment id="26156" author="madi33" created="Sun, 2 Dec 2012 01:50:56 +0100"  >&lt;p&gt;I&apos;m fine with zombies NOT chasing me...but yeah that does seem like a problem, now logically explained. And I love your weapon of choice...a shovel.&lt;/p&gt;</comment>
                            <comment id="26142" author="do" created="Sat, 1 Dec 2012 23:57:37 +0100"  >&lt;p&gt;Hmm, I tested this a bit and I think I&apos;ve got it figured out. There are two types of water block, running water (block id 8) and stationary water (block id 9). Zombies (and, I assume, other aggressive mobs, and maybe passive ones) don&apos;t seem to be able to move through stationary water, but they can move through running water fine. I still need to confirm that this is actually what I&apos;m seeing by looking at the data in chunks.dat, but I&apos;m almost positive this is the problem.&lt;/p&gt;

&lt;p&gt;Edit: this is definitely the problem. They can&apos;t move through block 9, but they can move through block 8.&lt;/p&gt;

&lt;p&gt;I tested it on Android by using PocketInvEditor to add eggs and both flowing and stationary water to my inventory. I also applied a patch that makes zombies spawn from eggs instead of chickens, with a 100% probability of spawning. I created a pool from each type of water, and threw an egg into the center of each pool. The zombie easily escaped from the block 8 water and pursued me. The zombie in the block 9 water was unable to move, and watched helplessly as I killed it with a shovel.&lt;/p&gt;

&lt;p&gt;The effect is especially noticeable when spawning a zombie on the other side of the block 9 pool... it will treat the pool as an obstacle and try to run around it instead of swimming to the other side. With a block 8 pool, the zombie swims across as expected. Interestingly, the zombie will go into the water at the very edge of the block 9 pool, but will not go any farther.&lt;/p&gt;

&lt;p&gt;The easiest way to recreate this on Android is to use the spawn egg patch, give yourself an egg, and throw it into naturally-occurring deep water, then swim up to the zombie and notice that he stays in one place.&lt;/p&gt;</comment>
                            <comment id="26127" author="madi33" created="Sat, 1 Dec 2012 22:56:25 +0100"  >&lt;p&gt;Unfortunately, I was unable to replicate a zombie in two block deep water... Turns out mobs only spawn when you DON&apos;T want them, haha. But, a creeper spawned and made it into the water... I think I had alerted it when I broke a dirt block next to it, causing it to explode.  So, that&apos;s not a good expiremnt...guess I shouldn&apos;t be a scientist. &lt;/p&gt;</comment>
                            <comment id="26118" author="do" created="Sat, 1 Dec 2012 21:51:21 +0100"  >&lt;p&gt;The hostile mobs don&apos;t seem to end up in the water as much, but once they&apos;re in there, they can&apos;t seem to get back out. It&apos;s my suspicion that the same logic that stops them from walking off cliffs also stops them from moving around when in deep water, but it&apos;s completely a guess, and I&apos;ve never tried to test it.&lt;/p&gt;</comment>
                            <comment id="26117" author="madi33" created="Sat, 1 Dec 2012 21:47:53 +0100"  >&lt;p&gt;I don&apos;t think it is related to that, I&apos;ve only found a few hostile mobs in water before.  I&apos;ll have to check about the two blocks deep thing. &lt;/p&gt;</comment>
                            <comment id="26106" author="do" created="Sat, 1 Dec 2012 20:47:18 +0100"  >&lt;p&gt;Possibly related to &lt;a href=&quot;https://bugs.mojang.com/browse/MCPE-992&quot; title=&quot;Mobs can&amp;#39;t move through deep water&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MCPE-992&quot;&gt;&lt;del&gt;MCPE-229&lt;/del&gt;&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Out of curiosity, if you fill in the bottom of the pool so the water is only two blocks deep, will the zombie start chasing you?&lt;/p&gt;</comment>
