From 71cd0199fda68a84c5f9a5252bf63e69712b177b Mon Sep 17 00:00:00 2001 From: "madmaxoft@gmail.com" Date: Wed, 27 Feb 2013 10:01:20 +0000 Subject: Made FAST_FLOOR_DIV work correctly, replaced all floorf() divisions with it. Still not perfect - chunk and region calculations can be made into a single CPU instruction - SAR - but not all compilers are known to support that (">>" operator on signed datatypes needs to perform arithmetic shift, C/C++ standard makes it implementation-specific; MSVC and GCC do what we need, LLVM unknown) git-svn-id: http://mc-server.googlecode.com/svn/trunk@1224 0a769ca7-a7f5-676a-18bf-c427514a06d6 --- source/WorldStorage/WSSCompact.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'source/WorldStorage/WSSCompact.cpp') diff --git a/source/WorldStorage/WSSCompact.cpp b/source/WorldStorage/WSSCompact.cpp index 87cf1d930..1d873add6 100644 --- a/source/WorldStorage/WSSCompact.cpp +++ b/source/WorldStorage/WSSCompact.cpp @@ -171,8 +171,8 @@ cWSSCompact::cPAKFile * cWSSCompact::LoadPAKFile(const cChunkCoords & a_Chunk) // ASSUMES that m_CS has been locked // We need to retain this weird conversion code, because some edge chunks are in the wrong PAK file - const int LayerX = (int)(floorf((float)a_Chunk.m_ChunkX / 32.0f)); - const int LayerZ = (int)(floorf((float)a_Chunk.m_ChunkZ / 32.0f)); + const int LayerX = FAST_FLOOR_DIV(a_Chunk.m_ChunkX, 32); + const int LayerZ = FAST_FLOOR_DIV(a_Chunk.m_ChunkZ, 32); // Is it already cached? for (cPAKFiles::iterator itr = m_PAKFiles.begin(); itr != m_PAKFiles.end(); ++itr) -- cgit v1.2.3
