The game makes sure that the player entity is never destroyed, but in
doing so, it doesn't destroy any duplicate player entities that might
have been created via strange means e.g. a custom level doing a
createentity with t=0.
Duplicate player entities are, in a sense, not the "real" player entity.
For one, they can take damage and die, but when they do they'll still be
stuck inside the hazard, which can result in a softlock. For another,
their position isn't updated when going between rooms. It's better to
just destroy them when we can.
This is similar to what was reverted in 3011911 but this time should use
syntax available even before C++11, tested on Clang with
`-std=c++98 -Wall -pedantic`.
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) have been replaced by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.
There's now a thin layer of UTF-16 around the WinAPI functions to get
the path to the Documents folder and to create a new directory, so that
account usernames with non-ASCII characters do not result in no VVVVVV
folder being created or used.
Resizing the vector does the same thing that the loops did, it changes
the size for the vector and initializes it with default-constructed
elements (or 0 or its equivalent for POD types).
Where a specific value is needed, it is set with the second
parameter of resize().
The next official VVVVVV build removes 32-bit Linux (like all my other games),
and I need to get rid of the shell script on macOS at some point, so this
basically brings it up to what my other games are doing. Plus, this probably
fixes a bug where someone tries to run their executable away from the root...
- Return in Unlock Play Modes goes to Game Options instead of the main menu
- changing some Graphics Options settings no longer plays two menu select sounds, which was really loud :(
- Return in Game Pad Options plays the menu select sound
- turning off Screen Effects plays the menu select sound
Follow-up to #19 which did the change for macOS.
It appears to work as expected on Linux too.
Tested on a distro where XDG_DATA_HOME is undefined by default,
and `PHYSFS_getPrefDir` also resolves to `~/.local/share/VVVVVV/`.
The first organization parameter is unused on Linux and macOS.
Instead use PHYSFS_getPrefDir which does the same than the manual
concatenation done before. The organization name argument is required
but is not used on macOS.
