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.
