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_v5.cpp | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'src/mapgen_v5.cpp') diff --git a/src/mapgen_v5.cpp b/src/mapgen_v5.cpp index 24c81e56d..16fe4be5d 100644 --- a/src/mapgen_v5.cpp +++ b/src/mapgen_v5.cpp @@ -290,8 +290,7 @@ void MapgenV5::makeChunk(BlockMakeData *data) // Calculate lighting if (flags & MG_LIGHT) - calcLighting(node_min - v3s16(0, 1, 0) - v3s16(1, 0, 1) * MAP_BLOCKSIZE, - node_max + v3s16(0, 1, 0) + v3s16(1, 0, 1) * MAP_BLOCKSIZE); + calcLighting(node_min - v3s16(0, 1, 0), node_max + v3s16(0, 1, 0)); this->generating = false; } -- cgit v1.2.3
