From 3955f512538ca7c6f2d2187f22d5a696da8e84d3 Mon Sep 17 00:00:00 2001 From: paramat Date: Mon, 13 Feb 2017 04:37:25 +0000 Subject: Objectpos over limit: Avoid crash caused by sector over limit Reduce the object limit by mapblock size, to avoid objects being added just inside the map generation limit but in a block and sector that extend beyond the map generation limit. Change notification of 'objectpos over limit' from red in-chat ERROR to in-terminal only WARNING, since this will happen often using mob mods near the world's edge. --- src/mapblock.h | 20 ++++++++++++-------- 1 file changed, 12 insertions(+), 8 deletions(-) (limited to 'src/mapblock.h') diff --git a/src/mapblock.h b/src/mapblock.h index 5a0ec937a..bec3b6f56 100644 --- a/src/mapblock.h +++ b/src/mapblock.h @@ -669,14 +669,18 @@ typedef std::vector MapBlockVect; inline bool objectpos_over_limit(v3f p) { - const float map_gen_limit_bs = MYMIN(MAX_MAP_GENERATION_LIMIT, - g_settings->getU16("map_generation_limit")) * BS; - return (p.X < -map_gen_limit_bs - || p.X > map_gen_limit_bs - || p.Y < -map_gen_limit_bs - || p.Y > map_gen_limit_bs - || p.Z < -map_gen_limit_bs - || p.Z > map_gen_limit_bs); + // MAP_BLOCKSIZE must be subtracted to avoid an object being spawned just + // within the map generation limit but in a block and sector that extend + // beyond the map generation limit. + // This avoids crashes caused by sector over limit in createSector(). + const float object_limit = (MYMIN(MAX_MAP_GENERATION_LIMIT, + g_settings->getU16("map_generation_limit")) - MAP_BLOCKSIZE) * BS; + return (p.X < -object_limit + || p.X > object_limit + || p.Y < -object_limit + || p.Y > object_limit + || p.Z < -object_limit + || p.Z > object_limit); } /* -- cgit v1.2.3
