this happens when you just copypaste and adapt r_lefthand
also did some minor changes to R_AliasDrawModel in the soft renderer
to make sure alias[xy]scale is reset properly in the early out cases
At high 'fov' values the weapon looked quite distorted.
Now it's rendered with an independent FOV, which looks better.
Note that the 'fov' cvar sets fov_x, while this is based on fov_y
(which is calculated from fov_x), so it's indeed different values:
r_gunfov seems to correspond to fov 90.
We use r_gunfov 80 as default, because it looks better.
The old code was working only when the client was connected to a local
server. The 'newgame' executed by the menu expands to a 'map', loading
a map ends in SV_InitGame() which calls CL_Drop() on the local client.
That calls CL_Disconnect() and everything is okay.
When the client is already connected to a remote server and no local
server is running the 'map' command spawns a new local server. This
new server thinks "Hey, I'm a new local server and no one is connected
to me. Let's pull the client in!". So it pull the already connected
client onto a new server without disconnecting, smashing it's state.
And everything goes down in flames.
The correct way would be to execute a 'disconnect' right before the
'newgame'. But the 'disconnect' cmd calls CL_Disconnect_f that throws
an ERR_DROP. ERR_DROP is implememted through a longjump(), jumping
around puts the process internal state in ashes... So bite the bullet
and add another hack: Call CL_Disconnect() before executing 'newgame'.
The 'game' command was more or less functional after the last commit.
We just need to reset the initialGame (renamed to userGivenGame) so we
don't revert back to the old game at server disconnect.
When connecting to a multiplayer game that runs a different mod
("game" cvar) than you are, it didn't load the corresponging configs
from the mod, but saved your changes to the config to the mod's config.
Which is doubly useless.
Now when the "game" cvar is changed, the configs are reloaded (from
the right directories for the mod), and when disconnecting the configs
are written, so the changes you did for a mod while playing MP are saved
before game is reset to the game you started with.
By default minizip uses fopen64(), fseek64() and so on. Those may not
be defined on all system, especially the BSDs. While FreeBSD already
has a special case, for example OpenBSD hasn't. Work around this by
forcing minizip to use fopen(), fseek() and so on everything that's not
Linux or Windows. This is not 100% correct, it may prevent the usage of
ZIPs lager than 2GB on Solaris and other rarely used systems. But I
doubt that anyone has such large ZIPs with assets, they would likely hit
other internal limits.
In the future Quake II should use off_t instead of int were applicable.
With that we could set -D_FILE_OFFSET_BITS=64.
This change is based upon a patch send by @devnexen in pr #279.
Until now we did an easy calculation to determine the frame timing:
1000000 microseconds (== 1 second) / targetframerate == delay between
frames. This works if the CPU and GPU are fast enough since the time
process to process the frame is negligible. But if one of them is too
slow or the GPU driver takes too long (see issue #277 for an example)
we render too few frames.
Work around this by calculating the average time used to process the
last 60 render oder packet frames and take that into account when
determining the delay between the frames. With this change even my
rotten AMD Radeon and it's broken Windows GL driver is able to hold
the displays famerate (enforced by vsync) just fine.
While here add a 5% security margin to our target packet frame rate if
the vsync is enabled. Just to be sure that we never process more render
than packet frames.
Modern LCD displays often haven't itegral refresh rates like 60hz but
fractional ones like 59.95hz. SDL communicates the refresh rate as
integer. On X11 the rate is rounded up or down with round(), but on
Windows it's (at least on my system with an AMD Radeon) truncated...
So on an 59.95hz display it's just 59hz, Quake II renders 0.95 frames
too few and the user sees microstutters.
And return the actual / requested display frame rate increased by one
to work around inaccuracies in Quake IIs internal timing. It should be
a problem if we're running a little bit too fast.
This is belived to fix at least a part of issue #277.
Refreshrate 2
The problem was that the cvars were only initialized (with CVar_Get())
if you opened the address book menu.
So if you start (and possibly run) and quit the game /without/ opening
that menu (or at least the "join network server" menu), the game will
not save those cvars to the config when it next writes it.
To prevent this, *always* initialize the cvars in M_Init().
There were two ways to implement this. One was to go with the stuff
already included in minizip and one to implement our own wrapper around
fopen(). This is the second options since @DanielGibson convinced me
that it would be safer.
