From: kwolekr Date: Mon, 18 May 2015 02:14:26 +0000 (-0400) Subject: Record MapBlock modification reasons as flags instead of strings X-Git-Tag: 0.4.13~253 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=46684beec185d13f89c4a91aaa5dd2148ebb0273;p=oweals%2Fminetest.git Record MapBlock modification reasons as flags instead of strings This improves performance of MapBlock::raiseModified by a factor of 6. Also, clean up mapblock.h a bit and inline small functions. --- diff --git a/src/environment.cpp b/src/environment.cpp index 96353dffb..dc18fd58f 100644 --- a/src/environment.cpp +++ b/src/environment.cpp @@ -873,7 +873,7 @@ void ServerEnvironment::clearAllObjects() if(block){ block->m_static_objects.remove(id);
