The client is improperly sending Item Name Packets to the server BEFORE
the click event. This causes the server to reset before the click event is processed
This breaks the ability to rename more than 1 item at a time.
See: https://bugs.mojang.com/browse/MC-111699
Spigot did not copy our version, and their version is not 100% correct.
The current state results in item meta and damage data value conversions clashing for control
For example on a horse egg, on itemstack creation, the 100 Damage is converted to 0 and sets EntityTag
SetItemMeta then drops the previous NBTTagCompound and makes a new one, which has no EntityType associated
to it as the previous stack had no metadata.
This change makes it so that itemstack conversion is delayed until after meta applies
Pretty much restores our previous implementation before Spigot tried to resolve it.
player.getVehicle() was returning null during the event. Paper had added lots of code to
cause the player to remount the entity on cancel.
I've simplified the diff and made player.getVehicle() work during the event by setting the
vehicle back during the event, and only set it to null if the event is not cancelled.
Take same approach we did for chunks, and only save player if its been X time since last save,
instead of doing it all in 1 tick.
This is even more helpful considering Player Saving is done sync for File IO.
Missed diff from old patch file was causing lava to always move at the
faster 'nether' speed, ignoring the slower overworld speed entirely.
This is why we use obfuscation helpers now.
Fixes GH-521
Every call to .isEmpty() made a horribly wasteful map lookup just to get the
reference to the Air Item for checking.
We will now cache a copy of that item
Allow configuring for cartographers to return the same map location
Also allow turning off treasure maps all together as they can eat up Map ID's
which are limited in quantity.
Make it so a Treasure Map does not target a structure outside of the
World Border, where players are not even able to reach.
This also would help the case where a players close to the border, and one
that is outside happens to be closer, but unreachable, yet another reachable
one is in border that would of been missed.
