If it&apos;s okay, could I request ownership since the reporter has been inactive for just under two years? I&apos;ll make all the necessary changes and will keep this ticket actively updated.

                            <comment id="39644" author="flapjacksmike" created="Fri, 25 Jan 2013 05:46:19 +0100"  >&lt;p&gt;Whether or not this is considered a bug or intended, this is visible in version 13w03a.&lt;br/&gt;
I also noticed that with knockback II that zombies will most launch horizontally out of the water rather than the proportional vertical movement like CubeTheThird said. It almost looks like they skip across the water like a rock rather than upwards.&lt;/p&gt;

                            <comment id="25338" author="cubethethird" created="Tue, 27 Nov 2012 14:11:20 +0100"  >&lt;p&gt;I recreated this with knockback II, and I have to agree that the vertical movement (though existant) seems disproportionately small compared to the horizontal movement. Whether or not this is intended, I am not sure. Next time please be as specific as possible when reporting an issue.&lt;/p&gt;</comment>
                            <comment id="25337" author="738dave" created="Tue, 27 Nov 2012 13:48:29 +0100"  >&lt;p&gt;I&apos;m refering to Knockback II, which is on my diamond sword together with Smite (IV level I think).&lt;/p&gt;</comment>
                            <comment id="25328" author="cubethethird" created="Tue, 27 Nov 2012 13:09:40 +0100"  >&lt;p&gt;Out of curiosity, are you refering to knockback 1 or 2?&lt;/p&gt;</comment>
                            <comment id="25324" author="738dave" created="Tue, 27 Nov 2012 11:18:48 +0100"  >&lt;p&gt;Well then it seems that you (Mojang) like it the way it is. I always imagined knockback as an extra power which is added to your punch and I imagined a punch to behave close to real-life punch.&lt;/p&gt;

&lt;p&gt;I&apos;ll try to describe it another way.&lt;br/&gt;
Imagine that you have a ball and throw it in front of you (that&apos;s example 1), then imagine that you throw a ball above your head (that&apos;s example 2). That&apos;s how I imagined Knockback to work and how it also make sense to me. If Mojang wanted it to behave like some kind of horizontal teleporter, then I&apos;ll accept it (with sad panda face).&lt;/p&gt;</comment>
                            <comment id="25264" author="cubethethird" created="Tue, 27 Nov 2012 01:00:52 +0100"  >&lt;p&gt;That is exactly what I did, attack from underwater, and the mob went both vertically (not by much mind you) and horizontally.&lt;/p&gt;</comment>
                            <comment id="25178" author="738dave" created="Mon, 26 Nov 2012 18:37:54 +0100"  >&lt;p&gt;I propably wasn&apos;t specific enough.&lt;/p&gt;

&lt;p&gt;Example 1&lt;br/&gt;
When you are normally on the ground and attack a mob with a sword with knockback enchantment, the mob will fly far away and very little high (just like you expected).&lt;/p&gt;

&lt;p&gt;Example 2&lt;br/&gt;
On the other hand when the mob is in water, you jump into water and swim underwater right under the mob (you look between it&apos;s legs) and then attack, you would expect the mob to fly really high into the air and not far away. Instead, it flies in the exactly same way as in the example 1.&lt;/p&gt;

&lt;p&gt;If this doesn&apos;t help then I&apos;ll try to draw it in MS Paint.&lt;/p&gt;

&lt;p&gt;EDIT: Also when you use Knockback II its even more visible and even more akward.&lt;/p&gt;</comment>
