            <title>[MC-8262] Airborne minecarts rapidly lose horizontal velocity</title>
                <link>https://bugs.mojang.com/browse/MC-8262</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;&lt;b&gt;What happens:&lt;/b&gt;&lt;br/&gt;
A minecart that runs out of track and has no ground directly under it will slow down at a fast rate.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;What I think should happen:&lt;/b&gt;&lt;br/&gt;
A minecart that runs out of track and has no ground directly under it should not lose any (or much) of its horizontal speed. An airborn minecart should only slow down quickly if it enters water or lava while falling.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;How to observe:&lt;/b&gt;&lt;br/&gt;
Build straight line of blocks floating high up in the air and place powered rails on top. Use either a redstone torch, redstone block, or a lever to give the rails constant power. Then, put a minecart on the track and push it so that it starts moving. Once the minecart runs out of track on the floating blocks you created, it will start to fall down. At the same time, it will begin to quickly stop moving forward (as if the air was dense like water).&lt;/p&gt;

If so, please &lt;em&gt;update the affected versions&lt;/em&gt; in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases. If this has been done, we can reopen the issue.&lt;/p&gt;

&lt;p&gt;Keep in mind that the &quot;Resolved&quot;-Status on this ticket just means &quot;Answered&quot;, and that we are waiting for further information on whether this issue still exists or not. It will be reopened as soon as the requested information has been delivered.&lt;/p&gt;

&lt;p&gt;The following is based on decompiled version of Minecraft 1.9 using MCP 9.24 beta. All method and class names are the names used in the decompiled version.&lt;/p&gt;

&lt;p&gt;The reason why this happens is very likely that the method &lt;tt&gt;net.minecraft.entity.item.EntityMinecart.moveDerailedMinecart()&lt;/tt&gt; clamps the motion for all three axes to the &quot;maximum speed&quot; (0.4d). This means that it rapidly drops from about 1.1d on the power rail to 0.4d.The problem is that clamping the value between two fixed values makes little sense because the slowing down looks pretty strange then. Additionally the factor used to slow down the minecart could be changed from &lt;tt&gt;0.949999988079071D&lt;/tt&gt; to a higher value or could be made dependent from the current motion in relation to the maximum speed.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;Note:&lt;/b&gt; Changes to this method will break existing minecart tracks.&lt;/p&gt;</comment>

Especially now that we have TNT minecarts. &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;</comment>
