From 7233a1228eb161cbcbb46c6e801cabd89ef3d2ab Mon Sep 17 00:00:00 2001 From: kwolekr Date: Sun, 4 Jan 2015 02:34:33 -0500 Subject: Lighting: Fix nearly all issues The cause of a single light source seemingly being lit without spread was due to its creation in the +Y mapblock boundary layer during map generation, which was ignored as the overtop. This overtop explicitly needs to be omitted during sunlight propagation, however. To accomplish this, Mapgen::calcLighting() was split into separate functions taking separate parameters. Additionally, do not diminish light too early during spread. This fixes the output inconsistency between Map::updateLighting and Mapgen::calcLighting. --- src/mapgen.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'src/mapgen.h') diff --git a/src/mapgen.h b/src/mapgen.h index aaa89d3bc..2ac66d354 100644 --- a/src/mapgen.h +++ b/src/mapgen.h @@ -156,7 +156,11 @@ public: void updateLiquid(UniqueQueue *trans_liquid, v3s16 nmin, v3s16 nmax); void setLighting(v3s16 nmin, v3s16 nmax, u8 light); void lightSpread(VoxelArea &a, v3s16 p, u8 light); + void calcLighting(v3s16 nmin, v3s16 nmax); + void propagateSunlight(v3s16 nmin, v3s16 nmax); + void spreadLight(v3s16 nmin, v3s16 nmax); + void calcLightingOld(v3s16 nmin, v3s16 nmax); virtual void makeChunk(BlockMakeData *data) {} -- cgit v1.2.3
