For some fucking reason, if you set an unsupported
SDL_GL_MULTISAMPLESAMPLES value on Windows (at least Win10 with Intel GPU
drivers, there 16 is unsupported), creating the Window and OpenGL context
will succeed, but you'll get Microsofts stupid GDI OpenGL software
implementation that only supports OpenGL 1.1.
Before these fixes, the GL3 renderer would just crash and the GL1 renderer
would fail to load, which caused the game to run in the background:
No Window, no Input, but sound was playing..
Now this problem should be handled properly and if initialization fails,
the rendering backend will be considered not working, and it will
try the gl1 backend next, and if that also fails it'll give up and exit
the game.
Until now the video menu enforced:
* fov set to 90 and horplus set to 1
* fov set to something other than 90 and horplus to 0
If the user hat configured another configuration through the console the
menu would reset it, even if only unrelated changes are applied. With
this change horplus is ignored by the menu and only fov is altered. The
rationale behind this is that most users want horplus enabled and all
others can disable it through the console.
This is believed to fix issue #225.
While here reimplement the same hack for baseq2/players, lost somewhere
on the way. This is just another searchpath f*ckup. For some reasons
paks have a higher priority than plain directories. We do not want that
for the maps.lst and players/ since id Software decided to put updated
versions of them directly into baseq2/...
This closes issue #217.
The variable yquake2RendererLinkerFlags is used to store the linker flags for opengl but the empty variable yquake2OpenGLLinkerFlags is used when linking libraries to the renderer.
Also there's no need to link the opengl libs to the opengl3 renderer when the glad extension loader is being used.
SDL_WINDOW_FULLSCREEN changes the display resolution if the requested
resolution is different to the actual resultion. SDL_WINDOW_FULLSCREEN_
DESKTOP doesn't do that, it places a smaller or bigger render area
somewhere inside the fullscreen area. This is somewhat nicer with modern
high resolution flatscreens.
This commit changes vid_fullscreen 1 from SDL_WINDOW_FULLSCREEN to
SDL_WINDOW_FULLSCREEN_DESKTOP. Additional vid_fullscreen 2 is
implemented, it uses SDL_WINDOW_FULLSCREEN to create the fullscreen
area.
TL;DR: Use vid_fullscreen 1 to keep the current resolution or use
vid_fullscreen 2 to switch the resolution.
Implementation details: The whole fullscreen stuff is a horrible mess.
Like generations of hackers before me I'm not desperated enough to clean
it up. GLimp_InitGraphics() is modified to take the fullscreen mode as
an integer and not as a boolean. That's a change to the renderer API.
In GLimp_InitGraphics() the needed SDL fullscreen mode flag is
determined once at the top and just used further down below. That saves
dome SDL1 <-> SDL2 compatibility cruft. IsFullscreen() was modified to
return the actual fullscreen mode and not just if fullscreen is enabled.
Several platforms - OpenBSD being a prominent example - don't provide a
way to get the executable path. Don't abort, just return the current
dir ./ executable dir. This is just a work around, of course. The user
needs to supply a script that calls ./quake2 in the correct directory.
The big problem with the old implementation was that stdout.txt and
stderr.txt on Windows became available when nearly all the low level
initialization was already done. Regardless if the client was in
normal or in portable mode.
Solve this by scanning the command line for the string '-portable'. If
it's not found, stdout and stderr are redirected as early as possible.
If found the global variable (*sigh*) is_portable is set to true. It's
evaluated later on to set the cvar 'portable', which in turn is used
be the filesystem to decide if the home directory should be added to
the search path.
Maybe we should remove the cvar and stick to the global variable.
While at it change the maximum path length for qconsole.log from
MAX_QPATH to MAX_OSPATH. At least on my Linux laptop MAX_QPATH is
too short.
This commit is still untested on Windows!
A new linked list fs_rawPath with nodes of type fsRawPath_t is added.
The new function FS_BuildRawPath() fills it at filesystem initialization
with the raw search path directories. Later FS_BuildGenericSearchPath()
and FS_BuildGameSpecificSearchPath() use it to derive the actual search
directories.
Remove all functions that are no longer used:
* FS_AddGameDirectory()
* FS_SetGameDir()
* FS_AddHomeAsGameDirectory()
* FS_AddBinaryDirAsGameDirectory()
While at it try remove as much global variables from filesystem.c as
possible. Also fix a small, longstandig bug: The download code should
treat .zip and .pk3 files as pak files and not as normal directories.
Refactor FS_SetGamedir() into FS_BuildGameSpecificSearchPath(). The new
function removes the specialized part of the search path if necessary
and create a new specialized part based upon the given directory. It
uses the FS_AddDirToSearchpath() function added in the last commit.
This moves the code used to add a directory and it's paks to the search
path into one well defined function FS_AddDirToSearchPath(). Also create
a new function FS_BuildGenericSearchPath() that builds the generic part
of the global search path. This obsoletes several other, specialized
functions. They'll be removed in a later commit.
This prevents Windows from scaling our (fullscreen) window to crap if
the whole desktop is scaled and we're rendering more than 1080p. This is
believed to fix#208.
if that cvar is set to 1, particles aren't rendered as nice circles, but
as squares, like in the software renderer or in Quake1.
Also documented it in cvarlist.md and fixed some typos there
Commit 883781c selected these paths for all OSs, but when linking to
a system copy of OpenAL for Linux distribution binaries we want the
normal OpenAL in /usr.
