Matthias Schiffer	fac2e4c8da	World: Chunk: add support for unordered sections ... MC1.18 doesn't always store sections sorted by their Y value, possibly related to "optimize world".	2021-12-12 12:18:18 +01:00
Matthias Schiffer	a2fe33ef1f	World: Section: add support for Int tag section Y values ... For some reason, MC1.18 sometimes uses Int instead of Byte tags for section Y values after "optimize world". Add support for this (but still only accept values that fit in a int8_t).	2021-12-12 12:15:31 +01:00

Matthias Schiffer	76e5d322b1	Resource: Biome: add biome palette name mapping ... For now we will continue to use the numerical biome IDs internally, as our biome storage format is based on these IDs.	2021-12-11 22:50:23 +01:00

Matthias Schiffer	457e993c92	Introduce separate types for block/section/chunk indices ... Newtypes are cumbersome in C++, so this is mostly documentation for now.

Matthias Schiffer	d4be401bcd	Resource: Biome: fix integer underflow ... Explicitly cast height value to signed integer to fix incorrect biome color values below a height of 64.	2021-12-11 22:28:22 +01:00
