For a long time, the script editor has had a bug where it would let you
put the cursor on a nonexistent script line, which would APPEAR to be
the last line of the script... but in reality, it WASN'T the last line
of the script, and in fact, the ACTUAL last line was the line ABOVE the
script.
So, if you typed anything on this nonexistent line, it would appear to
get erased when exiting the script. Thus, people have (erroneously)
misdiagnosed this as the script editor somehow being trigger-happy and
erasing lines when it shouldn't be, when in reality it should've have
let you gone onto that line in the first place!
The TinyXml functions to load and save files don't properly support
unicode file paths on Windows, so in order to support that properly, I
saw no other option than to do the actual loading and saving via PHYSFS
(or to use the Windows API on Windows and retain doc.LoadFile and
doc.SaveFile on other OSes, but that'd be more complicated and
unnecessary, we already have PHYSFS, right?).
There are two new functions in FileSystemUtils:
bool FILESYSTEM_saveTiXmlDocument(const char *name, TiXmlDocument *doc)
bool FILESYSTEM_loadTiXmlDocument(const char *name, TiXmlDocument *doc)
Any instances of doc.SaveFile(<FULL_PATH>) have been replaced by
FILESYSTEM_saveTiXmlDocument(<VVVVVV_FOLDER_PATH>, &doc), where
<FULL_PATH> included the full path to the saves or levels directory,
and <VVVVVV_FOLDER_PATH> only includes the path relative to the VVVVVV
directory.
When loading a document, a TiXmlDocument used to be created with a full
path in its constructor and doc.LoadFile() would then be called, now a
TiXmlDocument is constructed with no path name and
FILESYSTEM_loadTiXmlDocument(<VVVVVV_FOLDER_PATH>, &doc) is called.
