Items that cause entities to change state, including tags, chest, and
leashes, do not update the client properly following the firing of
PlayerInteractEntityEvent. This change makes the item checks occur
before the event fires, to concur with the client's assumptions.
This commit implements the ability to set the scale of hearts that the
client renders. When the Packet44UpdateAttributes packet is sent, the
max health attribute is replaced with a scaled version, to preserve the
scaled health illusion clientside.
In order to accurately display the scaled health for players, a true
health is stored within CraftPlayer, and the datawatcher now stores the
scaled health. The getHealth() method for players still returns their
true health.
Changed setHealth() within EntityLiving to appropriately handle health
for instances of EntityPlayer. Inlined a call to
setHealth(getMaxHealth()) within the EntityLiving constructor to work
around CraftEntity instantiation.
Additionally fixes the health values sent when eating food within
FoodMetaData and ItemFood, which previously sent the unscaled health;
this commit alters them to send the properly scaled health.
Additionally fixes BUKKIT-4535, BUKKIT-4536, and BUKKIT-4127
This changes livingEntity.addPotionEffect(PotionEffect, boolean) to
construct the MobEffect using the constructor that includes the ambient
setting as supplied by the PotionEffect
This also changes livingEntity.getActivePotionEffects() to construct the
PotionEffects using the ambient setting supplied by the MobEffects.
This change makes it so that EntityHuman#setPassengerOf(Entity) invokes
its parent method when leaving vehicles so that VehicleExitEvent is fired
for players leaving vehicles.
This change also fixes BUKKIT-2110, making it so VehicleExitEvent
correctly handles cancellation. The implementation of VehicleExitEvent
completely ignored the cancellation state of the event, making it so that
cancelling the event had no effect. Cancelling a VehicleExitEvent now
causes the entity to remain inside of the vehicle, with no visual stutter.
API has been added to interface with Horses and to modify their inventories. Horse entities will now be recognized with the type EntityType.HORSE, and will no longer be UNKNOWN.
HorseJumpEvent, EntityDamageEvent, and EntityTameEvent are all correctly fired for horses.
This commit fixes BUKKIT-4393.
Cancelling InventoryDragEvent causes the placed items to be lost. This is
because the cursor is set to the result prior to the event taking place,
so the items are removed from the cursor. When the event is cancelled, the
items removed from the cursor aren't placed in the inventory, and are just
lost.
This change sets the cursor back to the original cursor when the event is
cancelled.
Cancelling an InventoryClickEvent for a single click causes the click not
to be processed by the clicked inventory. The server then doesn't
correctly identify their second click as being a double click, causing an
inconsistency between what the Player believes the inventory to be and
what the server believes the inventory to be.
This change forces an updateInventory call whenever an InventoryClickEvent
whose action is NOTHING is cancelled. Both clicks are considered
PICKUP_ALL, so updating the inventory after the second click fixes any
inconsistencies that could arise between the client and the server.
Currently, the method used for calculating the damage of zombies is scaled
to their health, but it uses the default max health rather than the real
max health value. If zombies have more health than the default max health
value, the amount of damage they deal becomes negative.
This is caused by EntityZombie.getMaxHealth() returning a hardcoded value of
20, which is the vanilla max health for zombies. Rather than using this value
when calculating zombie damage, the call is changed to instead use
((CraftLivingEntity) this.bukkitEntity).getMaxHealth(). This uses the true
maximum health of the Entity. "this.maxHealth" could be used instead of the
aforementioned method, however that creates a very unclear diff, and a
confusing change.
When a Player drops an ItemStack while in creative mode by placing it outside
of their inventory window, the slot number in the packet is -1. The check
that was added to avoid throwing InventoryCreativeEvent excessively didn't
take this into account, and would cause an ArrayIndexOutOfBoundsException to
be thrown when attempting to get the slot specified by the packet.
This change shorts the invocation of player.defaultContainer.getSlot(
packet107setcreativeslot.b) to only occur if the slot id is within the range
of the Inventory. This prevents attempting to get the slot from a location
that is actually outside of the Inventory.
This commit brings the InventoryClickEvent up to date with the new Minecraft
changes in 1.5.
InventoryDragEvent (thanks to @YLivay for his PR) is added to represent the
new "dragging" or "painting" functionality, where if you hold an itemstack and
click-drag over several slots, the items will be split evenly (left click) or
1 each (right click).
The ClickType enum is used to represent what the client did to trigger the
event.
The InventoryAction enum is reserved for future expansion, but will be used to
indicate the approximate result of the action.
Additionally, handling of creative inventory editing is improved with the new
InventoryCreativeEvent, and handling of numberkey presses is also improved
within InventoryClickEvent and CraftItemEvent.
Also, cancelling a creative click now displays properly on the client.
Adresses BUKKIT-3692, BUKKIT-4035, BUKKIT-3859 (new 1.5 events),
BUKKIT-2659, BUKKIT-3043, BUKKIT-2659, and BUKKIT-2897 (creative click events).
We only go through event creation and calling when dispensing filled buckets
if the bucket is able to place its liquid. However, the check for this is
incorrect so the event is not called when a block liquids can destroy is
in front of the dispenser. This commit fixes the check to match the checks
vanilla does when actually using the bucket.
The CraftBlock class is setting bit 0x4 of the update flag when bit 0x2
should in fact be set here. Bit 0x2 means "do updates"; bit 0x4 means
"don't do updates if the world is static, even when bit 0x2 is set".
Minecraft 1.5.2 changed mob spawning by ignoring persistent mobs from the
mob count. In CraftBukkit all mobs that previously used a separate hard
coded persistence system were ported to instead use this one. This causes
all animals to be persistent by default and thus never be counted. To
correct this issue we consider if the mob would be considered persistent
in the hard coded system as well when deciding if a mob should count.
Currently there are several cases where a player will have their inventory
screen closed client side but we will not call an event. To correct this
we call the event when the server is the cause of the inventory closing
instead of just when the client is the cause. We also ensure the server is
closing the inventory reliably so we get the events. Additionally this
commit also calls the event when a player disconnects which will handle
kicks, quits, and server shutdown.
As an optimization we don't do any movement processing on entities that
have not moved. However, players in minecarts trigger this condition when
the minecart is moving on its own. This causes issues with things that rely
on player collision like tripwires. To correct this and any future related
issues we always handle movement for passengers and their vehicles even
if one of the two hasn't moved since they are linked.
