Slime blocks and the jump decay problem

With the new slime block's properties of a decayed bounce, the Decay of the bounce height is less the smaller the jump is, therefore, a smaller jump will produce a larger bounce proportionally (if I am correct in my test)
Tested Examples:(100, 75, 50, 25 and 12.5 were tested, the other results are in the .txt file)
A 100 M. Jump will make a 31.625 M bounce. 31.625 Percent of the original
Whereas a 12.5 M. Jump will make a 7.5 M bounce. 60 percent of the original
If this were to be extrapolated out, in some instances the bounce would reach 100 percent, but at very small values. It has what the computer sees as and infinitesimal

Due to the way this works, it seems that with certain heights that you jump from, the height does not always decay to zero. this causes the Ground test to spit out True/False Repeatedly. I believe this is due to the Ground test detecting such small changes that the y coordinate test cannot detect. Therefore it shows change, without the y coordinate necessarily "changing".

I Hope this helps to solve the problem.

This would explain the issue with trading with villagers standing on slime as well.... interesting.

Yes indeed, I Forgot to note that. I'm Running Further test to figure out some of the exact heights that create the ground detection bug. I will inform you when i have new information

With a 2 layer high snow (0.125 +y) above the slime, it always creates the ground detection bug. if you spawn a villager and push him off of the snow layers and onto the slime it always creates the villager gui bug.
Therefor the Villager GUI Bug is indeed directly related to this.

For Example:
if a villager falls from 1.125 y (1 block + 2 layers of snow) to 1 y (Onto slime) the GUI doesn't work correctly.

So in effect, the villager GUI bug is actually just this bug in relation to villagers.

The last part of the ticket describes MC-44352, though I don't believe that ticket covers everything here.

Is this still a concern in the current Minecraft version? If so, please update the affected versions 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.

Keep in mind that the "Resolved"-Status on this ticket just means "Answered", and that we are waiting for further information on whether this issue still exists or not. We will reopen it as soon as the requested information has been delivered.

Ticket resolved as incomplete, because no answer in a reasonable amount of time (1+ year), if it still happens, please update the ticket.
