Created Issue:
No knockback on y-axis when using the NoGravity tag
When you punch a mob from below, it doesn't receive any knockback upwards even if it has the NoGravity-tag. Same applies for knockback downwards if you're punching from above.
What I expected to happen was...:
The mob should be moving into the direction you are punching as it is getting pushed away from the player.What actually happened was...:
Instead, the mob only moves on the x- and z-axis and it isn't even considered whether you're punching from above or from below which is strange when you're in air.Steps to Reproduce:
{NoGravity:1b}
1. Set up a commandblock with the command "entitydata @e"
2. Set that commandblock into the repeat-mode and apply a redstone signal to it
3. Spawn some mobs
4. Punch them so they are in the air or spawn them above air.
5. Now try to punch them from above or below. You will notice that it isn't even considered in which direction you are punching and the mobs only move on the x- and z-axis.Environment

The command I gave in the bug report doesn't seem to work in the 1.13. snapshots anymore. It would be great if anybody knew how to fix the commandblock necessary for NoGravity-tests.
Done
Thanks a lot! I have added the command to my other reports as well

This feature was introduced in version 1.9. It modifies the game so that entities experience vertical knockback only when they have solid ground beneath them. This adjustment aims to prevent entities from being launched excessively high into the air.
