Clean up implementation and firing of both of these events by routing
both unload and load behaviors to consistent method calls.
This fixes issues where a few places would not call Load or Unload events
when it should have.
Additionally, reduces diff by moving the neighbor marking code into these
consistent points.
Additional benefits of the change include improving the neighbor marking
methods to use getChunkIfLoaded instead of getLoadedChunkAt in some places,
as the latter will cause chunks to be marked active and not unload.
Finally, this also updates CraftWorld.loadChunk to use the new methods, as the
previous logic did not properly handle the new unload queue.
Adds an check for existing entities before selecting the location allowing
for hanging entities to be spawned in blocks where there already is an
hanging entity at the default rotation.
Fixes the CraftHanging setRotation function to use the new 1.8 logic.
Related to SPIGOT-206.
Currently HangingEntities should be located next to the block they are
hanging on. With the direction set to the opposite of the block they
are hanging from.
This code is modified to find the correct direction.
In commit 6efeddfe57, TALL_REDWOOD was used instead of the proper TreeType
of MEGA_REDWOOD. Additionally, this fixes an issue in CraftWorld with an
improper boolean flag related to the generation of MEGA_REDWOOD trees.
23 classes have been removed as they are no longer needed using the new
capture logic. This should help quite a bit with future MC updates.
BlockPlaceEvent Refactor
Before calling Item.interactWith, a recording flag is turned on for
setTypeAndData to capture a blockstate for each block that attempts to be set.
When a block place event is cancelled, the recorded blockstate, stack
size, and metadata will revert back to the captured state. If the event is
not cancelled, a notification will be sent to clients and block physics
will be updated.
BlockChangeDelegate Refactor
Now that we have the ability to capture blockstates through world, there
is no need to modify world gen classes with BlockChangeDelegate. Instead
we will simply capture blocks during world generation in order to "replay"
all of the captured blockstates to send back to delegates.
StructureGrowDelegate and BlockSapling.TreeGenerator have also been
removed as part of this change. BlockSapling and BlockMushroom will
capture blockstates the same as block placement and revert back any grow
events if needed.
Previously, when a skeleton was spawned via the spawn(...) function, the
resulting skeleton had no equipped bow and therefore could not properly
attack. This fix gives all skeletons the proper equipment and ensures that
they are able to attack.
