In the 1.7.5 update the diff that called book edit events when editing
books was accidentally dropped because of nms changes within the file.
This commit re-adds the craftbukkit call to restore event behavior.
Teleporting a player checks to see if the player is disconnected to
try to avoid creating ghost players. The check it uses, however, randomly
fails when the player is in the middle of joining the server. The check
that would work correctly here does not work correctly when the player
actually disconnects. To work around this we add a new flag which is
cleared on the first tick of the new player and assume they are connected
if the flag is set.
If a plugin causes an entity to be removed from the world while the
world is ticking entities the ticking loop gets out of sync and fails due
to trying to go beyond the end of the entity array. To ensure this doesn't
happen we store the loop position as a field so we can fix it up in the
entity remove method just like the tick method does when it removes an
entity.
Books can now recieve more than one enchantment. As such, breaking out of
the loop after only 1 enchantment is applied is not the correct behavior.
This commit also reworks some of the logic surrounding the application of
enchantments to the item. By checking if the event doesn't add any
enchantments rather than if the original enchantments list is empty, the
application code is only reached if enchantments are applied, rendering
the "applied" boolean no longer necessary. The ItemStack's Item should only
be set once, so it is now set outside of the loop based upon whether or not
"flag" is true (with "flag" being whether or not the ItemStack's Item is a
book).
Previously any entities spawned through dispensers (monster eggs) or
by nether portals were given the incorrect SpawnReason of SPAWNER_EGG.
This made it impossible to distinguish what exactly happened in regards
to the creature being spawned.
A method in ItemMonsterEgg has been added to further fine tune reasons
for spawning creatures. This permits the DISPENSE_EGG reason to be used
correctly and accuratly as well as the NETHER_PORTAL reason due to how
BlockPortal spawns the mobs.
The redirected method, a(World, int, double, double, double), is still
called by the ItemMonsterEgg itself and therefore uses the default reason
of SPAWNER_EGG. This does not change previous behaviour.
Prior to this commit, a player disconnected during a respawn event would
remain in memory. This causes a ghosting issue of players in the slot
count and player list, as well as a reference leak.
This commit avoids re-adding the player to the player list (and world) if
they are disconnected. This ensures that the remainder of the respawn
logic is completed as well as ensuring a duplicate player is not left on
the server.
This commit also saves the player's file at the end of the method if they
have been disconnected to ensure that their next login is accurate to the
respawn event's actions. A player that was revived and disconnected will
reconnect as revived.
Currently we use the async chunk loading system only when players trigger
chunk loading. If a chunk is loaded for any other reason it goes through
a separate codepath. This means if a player has trigged a chunk load and
before the chunk loads something else wants the same chunk we will load it
twice and throw away the second result. With this change we instead use
the sync processing feature of the AsynchronousExecutor to load the chunk
which will pull it out of the queue if it was already queued to load. This
means we only ever load a chunk once. Because chunk generation is not
thread safe we still fallback to the vanilla chunk loading system if the
chunk does not currently exist.
Previously we attempted to call interact events in cases that were missing
by modifying the arm swing logic. This, however, was too broad and started
triggering events in cases we already covered leading to duplicates. Since
the only case we can handle cleanly and the primary point of the previous
fix was fluids we now instead simply treat fluids as air for this check.
This also ensures we do not get duplicate events when the player is in a
fluid and hits a normal block, unlike the previous change.
This reverts commit 68b702f7 and replaces it with a better fix.
The block obtained and stored within the block object higher up does not
reflect the block at the location being hit, rather it is the air block
the arrow was previously in. Thusly when the variable is used to check
if the arrow is still in the block, it fails.
In 1.7, Minecraft changed Weighted Pressure Plates to allow players and
entities to interact with them, rather than simply changing redstone signal
based on the number of items on the pressure plate. This commit adds calls to
PlayerInteractEvent or EntityInteractEvent for every entity that steps on the
plate.
The method being called was renamed during the 1.4.2 update process
but the function call was not replaced accordingly, leading to a
missed diff from 314051580a0a8e4745d3a539f232b552916eb302.
When falling back to vanilla recipes in the iteration of recipes,
a check is necessary to ensure that vanilla recipes are present.
RecipeIterator has been modified to account for the multi-map setup.
In commit f94b7af8 I delay removing the block until after running the
block's cleanup code to avoid errors. However, this causes problems of
its own due to blocks not being written with this in mind. To avoid blocks
getting recursively removed we now only delay removing containers since
they are the only ones we had problems with to begin with.
When setting a block the server sets the new block ID, calls the cleanup
on the old block, then calls the placement logic for the new block. This
would normally work correctly but we have logic to prevent errors that is
causing one here. When trying to clean up the old block we notice the block
ID has changed and try to fix things, this causes the cleanup logic to
fail. To ensure cleanup happens correctly we now do all the cleanup before
changing the block which avoids triggering the fixup code.
Due to vanilla blanket comparing data values, and the unspecified
order of hashmap iterators, we need to run through custom recipes
first, and therefore separately, to ensure that they are actually
used. By not adding the custom results to the experience table, we do
not override the experience gains from vanilla smelting recipes.
Setting a horse's passenger to a non-living entity will cause a
server crash when the horse ticks, we need to check that it is
a living entity before casting, and skip otherwise.
With the update in 1.7 that improved the server ping, it was made to
include a long version string for CraftBukkit. This value is too long
for proper display so we now send a shortened string consisting of
the server implementation and the minecraft version.
When we first added the reach limiter in CraftBukkit there was no
difference between how far the client could reach in vanilla while in
Survival or Creative. At some point in Minecraft's cycle Creative was
given a block extra to work with and our protection was not updated to
account for this. We need to respect the possibility of different game
modes in Minecraft providing the client with varying reach distances.
Due to an incorrect mapping of this method to a friendly name, we're
unfortunately calling the wrong method within EntityPlayer.reset() to
reset attributes. Instead of what we've mapped as "removeAllEffects", we
should be calling EntityLiving.aP(). This mapping should be corrected in
the next naming version.
In the CraftBlockState implementation, updating the blockstate onto
a block will force the block state data value onto the block.
Unlike vanilla which relied on block data being set when the type
changed, we must instead explicitely set the data in the blockstate.
Commit c576054539790bdeb35285f62863d74b48c0782d removed the chunklist
collection stored in ChunkProviderServer, however it has been partially
restored in some places by 7e1ac0a77129b169704c1e222ff2deb3ab6cd2d2. As
not all references to this were restored, this has caused the chunklist
and chunks collections to become out of sync, resulting in a memory leak.
This commit removes chunklist from ChunkProviderServer again.
When ItemDye is used to place a Cocoa Block, the postPlace() method
should not be called, as data is handled within the ItemDye class.
However, if Cocoa is placed via its block item, postPlace() should
still be called to mirror vanilla behavior.
