Skull blocks store their type in a tile entity and use their block data
as rotation. When breaking a block the block data is used for determining
what item to drop. Simply changing this to use the skull method for getting
their drop data is not enough because their tile entity is already gone.
Therefore we have to special case skulls to get the correct data _and_ get
that data before breaking the block.
On player death player PotionEffects need to be updated so that a player's
invisibility and other effects are removed, otherwise they will persist
after a respawn. This is a carry-over from our use of persistent player
entities.
Some features added in 1.4.2 use the difficulty value as an index to an
array so while before having it set to an invalid value would do nothing
or maybe cause an odd side effect somewhere it now crashes the server. This
patch ensures difficulty values are clamped between 0 and 3, inclusive.
Filtering item data is usually a good idea to make sure we don't have
invalid data or data on items that shouldn't have it. However, anvils
use item data in slightly different way and so running its code for
filtering here causes the data to be corrupted.
A couple method names were changed between 1.3.2 and 1.4.2 but were missed
in the update. One of these affects being able to enchant bows and the
other is used for updating player animations while firing.
Vanilla has its own handlers for plugin channel messages for things like
texture packs, books, and anvils. When vanilla handles one of these messages
we should not also pass it to plugins because they will be duplicating work
and potentially running in to situations our plugin system isn't setup to
handle. This is how 1.3.2 worked but was lost in the 1.4.2 update.
CommandMap now contains the functionality for tab completion. This
commit replaces the vanilla implementation and simply delegates it to
the Bukkit API.
This change affects the old chat compatibility layer from an
implementation only standpoint. It does not queue the 'event' to fire,
but rather queues a runnable that allows the calling thread to wait for
execution to finish.
The other effect of this change is that rcon connects now have their
commands queued to be run on next server tick using the same
implementation.
The internal implementation is in org.bukkit.craftbukkit.util.Waitable.
It is very similar to a Future<T> task, but only contains minimal
implementation with object.wait() and object.notify() calls
under the hood of waitable.get() and waitable.run().
PlayerPreLoginEvent now properly implements thread-safe event execution
by queuing the events similar to chat and rcon. This is still a poor way
albeit proper way to implement thread-safety; PlayerPreLoginEvent will
stay deprecated.
The implementation for the new methods mimics the old methods. The final
call for the old methods now maps to the new methods with an additional
call to get id.
If two players (or a player and any other entity) are teleported to the
same location in the same tick they will both get added to the other's
destroy queue then have a new entity spawn packet sent. Next tick the
destroy queue will be processed and they will then be invisible to each
other. To prevent this situation we remove the entity from the destroy
queue when sending out a spawn packet for them.
The new AI system introduced by Minecraft 1.2 no longer relies on the
target field in the entity so it is frequently out of sync with what the
entity is actually doing. This modifies the AI goal to update the target
so our API can return the correct information.
In 1.2.5 and older versions of CraftBukkit we allowed the use of data
values on bug mushroom and mob spawner blocks for use with plugins.
For the 1.3 update the mechanism for doing this was changed and I
accidentally used the wrong value when adding these, indicating that
they should not have data instead of our actual intent. This change
corrects this regression.
If a plugin calls player.hidePlayer(other); then player.showPlayer(other);
in the same tick the other player will be added to the entity destroy queue
then a spawn packet will be sent. On the next tick the queue will be
processed and a destroy packet will be sent that renders the other player
invisible. To correct this we ensure the destroy queue is in sync with use
of the vanish API.
In some situations an entity or tile entity can be added to the world but
have its own 'world' field be null or otherwise incorrect. As the entity
was added to this world to be ticked assume it actually is in this world.
An internal method for making the debug output for CraftScheduler's
async tasks was erroneously using the 'this' reference when the loop
should be referencing the current task.
This change was done to remove the internal sound names from the API.
Along with moving the internal names into CraftBukkit, a unit test was
added for any new sounds added in the API to assure they have a non-null
mapping.
