From ea12da939fdb0a8fd13de885d104af3031ffc3ac Mon Sep 17 00:00:00 2001 From: paramat Date: Fri, 29 Jul 2016 03:44:58 +0100 Subject: [PATCH] Mapgen: Remove unused 'flat' and 'trees' flags from mg_flags When the 'flat' and 'trees' flags were moved into mgv6_spflags they were left in mg_flags in an attempt to support old mgv6 worlds. However their appearence in mg_flags causes confusion, also, later, old-world support was found to be broken for mgv6 worlds with 'notrees'. This commit cleans up the mess and comes a month after a thread warning of the change, and explaining the required action, was posted in the news subforum. Only old mgv6 worlds with 'flat' or 'notrees' are affected, a small minority of worlds, the required action being correctly setting these flags in mgv6_spflags. Disable a section of the 'map settings manager' unit test which is to be changed as it is causing problems for pull requests. --- src/mapgen.cpp | 2 -- src/mapgen.h | 4 ++-- src/mapgen_v6.cpp | 10 +++++----- src/unittest/test_map_settings_manager.cpp | 8 ++++++-- 4 files changed, 13 insertions(+), 11 deletions(-) diff --git a/src/mapgen.cpp b/src/mapgen.cpp index b6fda91ac..fd4f5858f 100644 --- a/src/mapgen.cpp +++ b/src/mapgen.cpp @@ -50,10 +50,8 @@ with this program; if not, write to the Free Software Foundation, Inc., #include "dungeongen.h" FlagDesc flagdesc_mapgen[] = { - {"trees", MG_TREES}, {"caves", MG_CAVES}, {"dungeons", MG_DUNGEONS}, - {"flat", MG_FLAT}, {"light", MG_LIGHT}, {"decorations", MG_DECORATIONS}, {NULL, 0} diff --git a/src/mapgen.h b/src/mapgen.h index 5fcf2a365..403fb7470 100644 --- a/src/mapgen.h +++ b/src/mapgen.h @@ -30,10 +30,10 @@ with this program; if not, write to the Free Software Foundation, Inc., #define MAPGEN_DEFAULT_NAME "v6" /////////////////// Mapgen flags -#define MG_TREES 0x01 +#define MG_TREES 0x01 // Deprecated.
