From 47d07793654c1bdd92afbcb486e1ff1429f29a8f Mon Sep 17 00:00:00 2001 From: Paramat Date: Sun, 13 Oct 2019 00:18:23 +0100 Subject: [PATCH] Randomwalk caves: Reduce 'insure' value from 10 to 2 (#9035) This value reduces how far randomwalk caves can extend into the mapchunk padding, to avoid 'out of voxelmanip' cave nodes which cause flattened cave walls. Testing shows that a value of 2 (instead of 10) is enough to make 'out of area' nodes extremely rare. Reducing this value results in a higher chance of overlap and connection with caves of neighbour mapchunks. --- src/mapgen/cavegen.cpp | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) diff --git a/src/mapgen/cavegen.cpp b/src/mapgen/cavegen.cpp index fa34b7273..21540d7ce 100644 --- a/src/mapgen/cavegen.cpp +++ b/src/mapgen/cavegen.cpp @@ -364,9 +364,8 @@ void CavesRandomWalk::makeCave(MMVManip *vm, v3s16 nmin, v3s16 nmax, // Area starting point in nodes of = node_min; - // Allow a bit more - //(this should be more than the maximum radius of the tunnel) - const s16 insure = 10; + // Allow a bit more (this should be more than the maximum radius of the tunnel) + const s16 insure = 2; s16 more = MYMAX(MAP_BLOCKSIZE - max_tunnel_diameter / 2 - insure, 1); ar += v3s16(1, 0, 1) * more * 2; of -= v3s16(1, 0, 1) * more;
