Subject: [PATCH] Fix incorrect status dataconverter for pre 1.13 chunks
|
|
|
|
Vanilla was setting non-populated OR non-lit chunks to empty, but
|
|
really this is just completely wrong. It should be set to "carved"
|
|
at minmum, because pre 1.13 chunks went through 3 distinct stages
|
|
of generation: carving, population, and lighting - in this order.
|
|
There is no "empty" status, because a chunk was simply carved
|
|
or it didn't exist. So mapping any chunk data to empty is simply
|
|
invalid.
|
|
|
|
If the chunk is terrain populated, then obviously it must be at
|
|
minmum "decorated." If the chunk is lit and populated, then it is marked
|
|
"mobs_spawned" (which is what Vanilla is doing, and this is the last
|
|
stage before moving to full so it looks correct).
|
|
|
|
So now here is a table representing the new status conversion:
|
|
|
|
Chunk is lit Chunk is populated Vanilla
|
|
F F empty
|
|
T F empty
|
|
F T empty
|
|
T T mobs_spawned
|
|
|
|
Chunk is lit Chunk is populated Paper
|
|
F F carved
|
|
T F carved
|
|
F T decorated
|
|
T T mobs_spawned
|
|
|
|
This should fix some problems converting old data, as the
|
|
changes here are going to prevent the chunk from being regenerated
|
|
incorrectly.
