To handle changes in 1.7.9 we changed skull meta to use GameProfile
instances instead of strings of player names. This reflects what vanilla is
actually storing for skulls now. As skulls still require a name our API was
not changed and we instead look up the rest of the profile information from
the name. The way this was implemented made it so that deserializing a skull
or setting its name potentially involved a network request. As skull meta
itself does not actually require a complete profile we now simply create one
that only contains a name and leave populating it to the server when it is
actually needed.
With the current API it is possible to create an inventory with a specific
type, but it is not possible to give such an inventory a title other than
the default.
The commit changes that by adding a method to optionally supply the title
for the given inventory type and holder, creating the functionality to
display any supported inventory type with a 32 character length String.
If the inventory title supplied is larger than 32 characters then an
IllegalArgumentException is thrown stating so.
The AnvilInventory reports its size as the sum of the ingredient and
result inventories, but when trying to access the slots, only the
ingredient inventory is used, leading to an ArrayIndexOutOfBounds exception.
This change overrides getItem(I) and setItem(I) to use both inventories,
with the slot number adjusted based on their size.
Previously, the SlotType for the last 4 slots in a player's inventory
returned QUICKBAR when it should have returned SlotType.CONTAINER. This
updates the code for determining slot type to return the proper value.
Previously, the SlotType for the 0 slot in a furnace returned CONTAINER,
when it should have returned SlotType.CRAFTING. This updates the code for
determining slot type to return the proper value.
When working with inventories you regularly end up with different
Inventory objects that have the same underlying Minecraft inventory.
Currently, even those these point to the same thing, they are not
considered equal. With this commit comparing any Inventory object that
represents the same inventory will result in equals(Object) returning
true.
ItemStacks do not stack if one has null for a tag, while the other has an
empty tag. In CraftItemStack, if you set an item to an empty ItemMeta, it
will create an empty tag for the internal ItemStack.
This changes the setItemMeta function to check for empty meta, and then
use null for the tag instead of an empty NBTTagCompound.
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.
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.
The recent Minecraft update rendered the
e20e50f85083dc53cb5456254bcf5781ef750daa fix incorrect by adding a
compound name to the base tag in some code. This fix changes all uses
of tag changes to explicitly use a name.
Opening a hopper inventory created by Server.createInventory will
currently have no effect as proper handling code is missing in
CraftEntityHuman for hopper inventories that aren't associated with a tile
entity or minecart. Initialization logic for hoppers is also missing from
CraftContainer, which is necessary for the opening of custom hopper
inventories.
This commit fixes the two aforementioned by adding proper handling to
CraftHumanEntity for opening inventories not associated with a tile
entity, and by adding initialization logic for hoppers to CraftContainer.
Custom inventories currently do not validate the titles provided. Null values
cause NPEs when writing packets. Values longer than 32 characters
disconnect clients.
This change throws and IllegalArgumentException for null titles or titles
longer than 32 characters.
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.
When an array of an inventory's contents is requested, we loop through the contents of the NMS inventory's ItemStacks in order to return Bukkit ItemStacks that can be used through the API. However, the NMS ItemStack can, in some cases, be larger than the physical size of the inventory. Using the size of the NMS array as a limit on the loop that follows can result in an ArrayIndexOutOfBoundsException because the Bukkit array's length is the actual size of the inventory, and thus will be smaller.
With this commit we use the smaller of the two arrays' length as the limit in the loop, thus eliminating the possibility that the smaller array will be asked for an index higher than its length.
When cloning an item, all references are copied to the new item. For
collections, this makes internal changes become visible in both the old and
new items.
In CraftMetaItem, clone was not making copies of the appropriate collections
and has been fixed for non-null values.
In CraftMetaEnchantedBook and CraftMetaPotion, clone was using possible empty
collection references and has been changed to explicitly null-check instead.
Fixes BUKKIT-3408, BUKKIT-3190, BUKKIT-3191, BUKKIT-3407
These changes relate mostly to semantical changes for serialization
contract, exception of changing the map scaling value from byte to boolean,
what it should have been in the first place. Appropriate unit tests were
added for CraftMapMeta, as they were missing.
An ItemStack gains the tag name "tag" when the stack is serialized
to NBT, however items don't have a tag *until* they are serialized at
least once. So to solve this, we remove the tag name when loading the
NBT data.
Another problem with NBT are TagLists, when transferring tag lists
between the server and the client the names are lost, and so we
simply don't add a name to the tag.
Some meta functionality is refactored into common methods.
CraftItemStack uses the ItemMetaKey identifiers for enchantments.
Refactored unit test to include extra functionality; initially only
checking the presence of the DelegateDeserialization annotation.
The purpose of the isSimilar method was designed to consider all NBT
data, not solely enchantments, without the need to have exact stack
size matches. The respective methods in CraftInventory were still
comparing enchantments instead of the ItemMeta.
