From b8237099b269011f16a8055a61745876768f3f4d Mon Sep 17 00:00:00 2001 From: paramat Date: Tue, 20 Jun 2017 04:55:32 +0100 Subject: Mgv5/v7/fractal: Add 'large_cave_depth' parameter to replace fixed value The value cannot be fixed because we can shift terrain vertically. This also makes these mapgens consistent with mgflat and mgvalleys which have 'large_cave_depth' parameters. --- src/mapgen_fractal.cpp | 71 ++++++++++++++++++++++++++------------------------ src/mapgen_fractal.h | 4 +-- src/mapgen_v5.cpp | 5 +++- src/mapgen_v5.h | 4 +-- src/mapgen_v7.cpp | 5 +++- src/mapgen_v7.h | 2 ++ 6 files changed, 51 insertions(+), 40 deletions(-) (limited to 'src') diff --git a/src/mapgen_fractal.cpp b/src/mapgen_fractal.cpp index 6806b8cbf..a99b3006b 100644 --- a/src/mapgen_fractal.cpp +++ b/src/mapgen_fractal.cpp @@ -49,17 +49,18 @@ FlagDesc flagdesc_mapgen_fractal[] = { MapgenFractal::MapgenFractal(int mapgenid, MapgenFractalParams *params, EmergeManager *emerge) : MapgenBasic(mapgenid, params, emerge) { - this->spflags = params->spflags;
