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	d18e004743	World: Section: fix biome palette size check ... We were accidentally checking the block type palette size.	2021-12-12 10:28:17 +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. Also replace lots of questionable uses of size_t with int or types with explicit width and add a few comments for constants.	2021-12-11 22:50:23 +01:00

Matthias Schiffer	ae68c3bab4	Add quirk for stone_slab rename ... The old stone_slab block from pre-1.14 has been renamed to smooth_stone_slab, and the name stone_slab was reused for a new block. Resolve the palette entry depending on the chunk's dataVersion.	2019-05-25 19:51:28 +02:00
