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	aacea26716	World: add support for negative Y coordinates and MC 1.18 chunks ... MC 1.18 biomes are not handled yet.	2021-12-11 22:50:23 +01:00

Matthias Schiffer	0f6c467566	World: Chunk: replace division/modulo with shift/mask for height values ... Preparation for negative y coordinates.	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. 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
