From 0b23253447623cadf1c394984ce0eee977d54b9b Mon Sep 17 00:00:00 2001 From: Paramat Date: Fri, 8 Jun 2018 23:24:36 +0100 Subject: Mapgen flags: Add 'biomes' global mapgen flag (#7355) Previously the only way to disable biomes was to 'clear' the registered biomes in a mod, but this method causes large amounts of unnecessary processing: 1. Calculation of 4 2D noises. 2. Looping through all nodes of a mapchunk replacing nodes with identical nodes. The new flag disables those operations. --- src/mapgen/mapgen_valleys.cpp | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'src/mapgen/mapgen_valleys.cpp') diff --git a/src/mapgen/mapgen_valleys.cpp b/src/mapgen/mapgen_valleys.cpp index 843acb690..341ce3137 100644 --- a/src/mapgen/mapgen_valleys.cpp +++ b/src/mapgen/mapgen_valleys.cpp @@ -231,7 +231,8 @@ void MapgenValleys::makeChunk(BlockMakeData *data) updateHeightmap(node_min, node_max); // Place biome-specific nodes and build biomemap - generateBiomes(); + if (flags & MG_BIOMES) + generateBiomes(); // Generate tunnels, caverns and large randomwalk caves if (flags & MG_CAVES) { @@ -265,7 +266,8 @@ void MapgenValleys::makeChunk(BlockMakeData *data) m_emerge->oremgr->placeAllOres(this, blockseed, node_min, node_max); // Sprinkle some dust on top after everything else was generated - dustTopNodes(); + if (flags & MG_BIOMES) + dustTopNodes(); updateLiquid(&data->transforming_liquid, full_node_min, full_node_max); -- cgit v1.2.3
