Subject: [PATCH] Allow Blocks to be accessed via a long key
|
|
|
|
The key can be retrieved via methods Location#toBlockKey() and
|
|
Block#getBlockKey()
|
|
|
|
World provides lookup for blocks by long key via method World#getBlockAtKey(long)
|
|
|
|
The formatting for the key is as follows:
|
|
|
|
10 bit y|27 bit z|27 bit x
|
|
|
|
The y value is considered unsigned while z and x are considered two's complement
|
|
|
|
Y range: [0, 1023]
|
|
X, Z range: [-67 108 864, 67 108 863]
