Lua Projects: Xcode/MSVC

You can now find the lua project files up on github. I have modified the lua configuration to use floats instead of doubles. This change does have a few side effects.

Old luaconf.h

#define LUA_NUMBER_DOUBLE
#define LUA_NUMBER  double
#define LUA_NUMBER_SCAN     "%lf"
#define LUA_NUMBER_FMT      "%.14g"

Modified luaconf.h

//#define LUA_NUMBER_DOUBLE
#define LUA_NUMBER  float
#define LUA_NUMBER_SCAN     "%f"
#define LUA_NUMBER_FMT      "%.8g"
