Subject: [PATCH] Improve Structures Checking
|
|
|
|
Improves performance by keying every chunk thats part of a structure to a hashmap
|
|
instead of only the first one.
|
|
|
|
This allows us to avoid iterating the entire structures value set to see
|
|
if a block position is inside of a structure.
|
|
|
|
This should have pretty decent performance improvement to any standard world
|
|
that has been around for a whilewith lots of structures due to ineffeciencies
|
|
in how MC stores structures (even unloaded chunks has structured data loaded)
