- Lots of itemstack cloning removed. Only clone if the item is actually moved - Return true when a plugin cancels inventory move item event instead of false, as false causes pulls to cycle through all items. However, pushes do not exhibit the same behavior, so this is not something plugins could of been relying on. - Add option (Default on) to cooldown hoppers when they fail to move an item due to full inventory - Skip subsequent InventoryMoveItemEvents if a plugin does not use the item after first event fire for an iteration

Subject: [PATCH] use CB BlockState implementations for captured blocks
|
|
|
|
When modifying the world, CB will store a copy of the affected
|
|
blocks in order to restore their state in the case that the event
|
|
is cancelled. This change only modifies the collection of blocks
|
|
in the world by normal means, e.g. not during tree population,
|
|
as the potentially marginal overheads would serve no advantage.
|
|
|
|
CB was using a CraftBlockState for all blocks, which causes issues
|
|
should any block that uses information beyond a data ID would suffer
|
|
from missing information, e.g. Skulls.
|
|
|
|
By using CBs CraftBlock#getState(), we will maintain a proper copy of
|
|
the blockstate that will be valid for restoration, as opposed to dropping
|
|
information on restoration when the event is cancelled.
