With this renamed cvars can be rewritten when config.cfg is first
loaded. Please note that once this was done older YQ2 versions can't
parse that config.cfg anymore.
gl_maxfps > 1000 breaks things, and cl_maxfps starts to behave weird
at >90, and while up to 125 or so you get the bugfeature of higher
jumping, beyond that things just get even buggier, at some point causing
bugs like #261
The original client used single precision mode on Windows and the
default mode on all other platforms. Most platform (at least OS X,
FreeBSD, NetBSD up to 6.0, OpenBSD and Solaris) set double precision
as default, Linux sets extended double precision... When playing a
network game there're several possibilities:
* Same precision on both sides: This one is okay, of course.
* single precision <-> double precision: This one is okay, too. I guess
this is because the code allows a small deviation between client and
server to work around imprecisions introduced be the network protocol.
* double precision <-> extended double precision: This one is okay,
likely for the same reasons given above.
* single precision <-> extended double precision: This one gives a lot
of misspredictions at client side.
All of these are more or less academic these days. Yamagi Quake II used
the platforms default mode for ages. And both gcc and clang default to
SSE2 math (with double precision as default on all platforms) when
compiling for amd64. So the only reasonable case is Linux/i386 on one
side and the original client or another source port on Windows/i386 at
the other side.
Work around this by forcing the x87 to double precision mode.
Miscframes are coupled to renderframes and are just checking for
renderer changes (very cheap) and advancing CD audio if implemented.
There's no reason not to that at every frame.
Until now the curtime variable was set at every call Sys_*seconds().
That's a little bit unfortunate because calls to that functions are
scattered around the code. Instead set it once every frame in
Qcommon_Frame().
Yes, this duplicates some code. But it's at least 100 times more
readable to have two distinct functions for distinct purposes instead
of about 25 #ifdef.
Having the server in an own timing zone seems to simplify things but
introduces slight timing discrepancies. The most visible effect is that
the game runs a little bit too fast, especially in the first cl_maxfps
frames.
Therefor: Remove timeframes, they're unnecessary. Track the time since
the last (client|server) frame instead and pass it to the client and
server when it's called.
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.
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.
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 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.
Resurrect support for render / refresher loadable libraries and use them to implement an experimental OpenGL 3.2 renderer. Please note that the new renderer interface is somewhat different from the original one, old render libraries will NOT work!
