 Description   

While testing MC-4167 discovered that XP Orbs would be invisible for one second "switching location" like described in MC-4167.

To reproduce:

  • Kill a mob, watch how no XP is visible right after the corps disappears in smoke particles
  • Mine a diamond ore, xp appears 1 second after mining it
  • breed animals
  • throw a bottle o' enchanting, same effect

Confirmed for release 1.8

Confirmed for 14w29b.

Solution (MCP Names):
in NetClientPlayHandler's handleExpOrb or something similar, the coordinates of the xp orb are retrieved from the packet and used in the constructor of a new EntityXPOrb. However, those coordinates are still 32x the actual coordinates (to aid in network communication)
So simply divide each coordinate by 32.0D and the problem is fixed

Still a concern in 14w08a.

Confirmed for 13w48b.

Confirmed in 1.7.1

Just wanted to point out that this issue describes XP being invisible for one second, but many linked duplicates are describing different behavior, including intermittent or no visibility at all.

Personally, in 39b I have never seen any XP.

present in 13w39b. I briefly saw some after I killed the ender dragon, but they disappeared before they hit the ground. Annoying because I'm not sure I collected it all.

Comment by WolfieMario [ 14/Sep/13 ]

Confirmed for 13w37b.

Comment by Rene Schindler [ 06/Jul/13 ]

still in 1.6.2 pre-release

Comment by Ben W [ 28/Jun/13 ]

Still in 1.6 prerelease.

Comment by fake fakes [ 19/Jun/13 ]

Still in 13w25b

Comment by Tom Willshire [ 19/May/13 ]

This is really annoying, I can't tell whether or not I picked up all the XP from something I killed and I have to go back.

Comment by Ben W [ 14/Apr/13 ]

Most noticeable to me when mining (the sounds play and the XP bar fills, but no orbs are visible; occasionally I'll see one if I'm far enough away), but I have observed with XP from mobs as well.

Confirmed.
