Up until Minecraft version 1.5 it was not possible to teleport entities
within vehicles. With the 1.5 update came the change in the Minecraft
teleportation logic to dismount before teleporting the entity, if
applicable.
This commit ammends the existing CraftBukkit logic for rejecting
teleportation for entities in vehicles to permit the action. Due to this
change, CraftBukkit is now in-line with Minecraft 1.5 teleportation logic.
When a player dies their inventory is normally scattered over the the area
in which they died. Plugins should be able to modify this behaviour by
defining whether or not the player's inventory will be dropped on the ground or waiting for the player when they eventually respawn.
This commit implements the methods included in the Bukkit half for the new
behaviour by acting upon the boolean flag. The boolean flag is tested
prior to clearing the inventory as well as prior to dropping the items on
the ground. If the flag is true (indicating "keep inventory"), the items
are not removed from the player's inventory and are not dropped on the
ground.
When using a "vanilla" Minecraft server using the "pick block" key on a
command block yields the invoker with a command block within their
inventory while in creative mode. Implications of the invalid items set
containing the command block also include having a "ghost" item that
cannot be placed due to it not actually existing.
This commit resolves the problem and brings Craftbukkit closer to vanilla
behaviour by removing the command block item ID, 137, from the invalid
items set.
Prior to this commit cancelling the PlayerFishEvent would cause various
states of the fishing routine to be incorrectly or wrongly fired. This
incorrect behaviour was due to the miscommunication between the server and
client regarding the fishing state. When the event was cancelled, the
bobber entity was removed and caused the client to incorrectly determine
what the "next state" was to logically be.
This commit resolves the issue by ensuring the client is made aware of the
correct changes at the correct time regarding the bobber entity, therefore
keeping the logical steps of "fishing" proper and in-tact.
Up until this commit the PlayerDropItemEvent, if cancelled, would return
items to the first available slot in the inventory - which is clearly
undesirable as a player and plugin author to deal with.
This commit changes that by ensuring that the item is returned to where
it came from in the player's inventory. This still supports modifying the
drop from the player and will default to "first available slot" if the
item has changed since the event was fired. Other remaining behaviour of
the event is still in tact and has not been modified.
This change improves the quality of life for plugin developers using
iterator iteration with side-effects. In the specified Guava patch, the
internal iterator no longer relies on the AbstractList iterator which
iterates by index, and will instead wrap the provided iterator in a
transformer given the Function.
Many chunk sections contain parts of their data that are the same for
every block they contain. In these cases we can save memory by saving
a single value instead of an array of 4096 copies of that value. Block light
and block data are most likely to be uniform followed closely by sky light
data. Block ids are far less likely to be uniform but give the largest
saving when they are. Because of this we use a compact format for every
part of the chunk. Memory saved from this technique will vary based on the
world but seems to be about 50% on normal Minecraft generated chunks.
