public static class ChunkLightProvider.class_8531 extends Object
Methods for manipulating a set of bitflags with yet unknown functionality.
  • Bits 0 – 3 likely store a light level.
  • Bits 4 – 9 store a flag for each of the six directions.
  • Bit 10 stores whether the block at this position is trivial for lighting — if its opacity is not directionally dependent.
  • Bit 11 stores a flag with unknown function.
