This allows us to implement the global timing without an artificial
brake slowing the game unnecessary down. This is only partial working,
more changes and fixes are coming.
This is a no-op for now. We need this to get a much higher precision
when calculating the frame times. This changes the fixedtime cvar from
milli- to microseconds.
This is the same as the client does for it's realtime. It looks at least
somewhat more correct since it pevents rounding errors. And things are
simplified a litte bit since the server timing is now independent of the
global timing.
The old framecounter had two problems:
* It measured only the time of the current render frame, not the total
time spend between the last and the current render frame. Therefor the
calculated value was too high.
* It was based upon milliseconds and rather inaccurate.
This new frame counter solves both problems. The total time spend
between two render frames is measured and the measurement done in
microseconds.
There're three modes:
* cl_drawfps 1 displayes the average frame rate calculated over the last
60 frames.
* cl_drawfps 2 displays a nice string with minimal framerate, maximum
framerate and average framerate. All three values are calculated over
the last 60 frames.
* cl_drawfps 3 is the same as number 2 but with a second line showing the
raw values.
TODO:
* Discuss if cl_drawfps should be renamed to cl_showfps. All other
status displays are named cl_show*.
While at it remove several unsused drawing functions.
This is the same as the well known Sys_Milliseconds() but like the name
suggests with microsecond precision. To be used in the upcoming new
framecounter.
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.
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
The model shadows are rendered after all entities are rendered.
This fixes them making entity brushes below them translucent (#194)
The model rendering code used lots of global variables, many of them
totally superfluous (esp. currententity, currentmodel).
I refactored the code to use less global variables (this was at least
partly needed to render the shadows later).
So this looks like lots of changes, but many of them are just using
"entity" instead of "currententity" or "model" instead of "currentmodel"
Like GL1 gl_shadows + gl_stencilshadows: no shadow volumes, but looks
ok apart from standing over edges
The gl_stencilshadows cvar isn't used in GL3, it always uses the stencil
buffer if available (and if gl_shadows != 0)
This still needs performance optimizations: Like the GL1 impl it takes
lots of draw calls per model, it could be done with one per model like
when rendering the actual model.
