There's an "enable alt joy keys" command now. If a key is bound to that
command, all joystick buttons (incl. hat and triggers) are turned from
K_JOYx into K_JOYx_ALT, which allows two keybindings on the same key,
one with the altselector pressed and one without.
If there's no keybinding for K_JOYx_ALT, it will use the binding for
just K_JOYx as a fallback (if it exists).
This is especially handy to create direct bindings for all the weapons
on the (limited amount of) Joystick buttons.
Seems like AMDs Windows driver doesn't like it when we call
glBufferData() *a lot* (other drivers, incl. Intels, don't seem to
care as much).
Even on an i7-4771 with a Radeon RX 580 I couldn't get stable 60fps
on Windows without this workaround (the open source Linux driver is ok).
This workaround can be enabled/disabled with the gl3_usebigvbo cvar;
by default it's -1 which means "enable if AMD driver is detected".
Enabling it when using a nvidia GPU with their proprietary drivers
reduces the performance to 1/3 of the fps we get without it, so it
indeed needs to be conditional...
use GL3_BufferAndDraw3D() instead of glBufferData() and glDrawArrays()
in each place it's needed.
This by itself doesn't make anything faster, but it will make trying out
different ways to upload data easier.
The developers tested their maps without the fix and decided that it
looked good. Add a new cvar gl_fixsurfsky defaulting to 0 that enables
the fix if someone really want it.
The software renderer already did this, but not the GL renderers. Maybe
the logic was lost somewhere on the long way... Without this change a
fullbright lightmap is generated for SURF_SKY surfaces and without the
SURF_DRAWSKY flags the surfaces aren't skipped in RecursiveLightPoint()
and GL3_LM_CreateSurfaceLightmap(). This isn't a problem under real
skyboxes, but in cases were SURF_SKY is abused fpr interior lightning.
rmine2.bsp in rogue is a good place to see the problem
Reported by @m-x-d, fixes#393.
I guess it makes sense to apply gamma to the color, we do the same
for the standard round particles.
Also, this way the fragment shader for square particles references the
uniCommon UBO (gamma is part of it) - apparently the Intel HD4000
(from Ivy Bridge) GPU driver for Windows has a bug that uniform blocks
that exist in the shader source but aren't actually used can't be found
(with glGetUniformBlockIndex(prog, name)), which we treat as an error
in gl3_shaders.c initShader3D().
fixes#391
Apparently the lightsource for exploding rockets/grenades is very close
to the surface, so the dot-Product between surface-normal and the
vector between the light and the pixel returns 0, basically disabling
the dynamic light for that surface.
As a workaround, move the lightposition (only for that dot product)
a bit above the surface, 32*surfaceNormal looks good.
fixes#386
The real needed size can't be derived from the .bsp file size, because
* many generated structs contain pointers
* there's lots of data generated per face..
* _especially_ for warped faces that are subdivided
introduced FS_GetFilenameForHandle(fileHandle_t) for this
this helps if a map has been started with "wrong" case, which doesn't
immediately fail if it has been loaded from a pack, but will result
in invalid savegame names that (with case-sensitive FSs) will fail to
load (when going back to a formerly played level)
The r1q2 code prioritized pak files over all other files, e.g. as soon
as a pak file was requested no more file were added to the download
queue until it finished downloading. That way one could be sure that
assets included in the pak file weren't downloaded in parallel as single
files.
This is a better, bugfixed and more robust implementation of the same
logic. With this back in place we can switch back to parallel downloads
which gives a nice speedup on Windows. Maybe, just maybe some day
Microsoft will fix Windows crappy I/O...
Working with getter and setters was a good idea as long as we had one or
two quirks. Now we're at three with maybe more to come so it's easier to
use a struct to communicate quirks between the precacher and the HTTP
download code.
The stores it's text in the key_lines array which is NUM_KEY_LINES *
MAXCMDLINE chars long. The code never checked for overflows, it just
assumed that a line will never be longer then 256 chars * 8 = 2048
pixel. With modern displays we can have higher vertical resolutions,
so the array will overflow sooner or later.
Fix it by clamping the maximum line width to MAXCMDLINE - 2 chars (1
for the prompt and 1 for the terminating \0). While at it increase
MAXCMDLINE to 1024 chars * 8 = 8192 pixel, which is more then 8k
resolution and should be enough for the years to come.
This is belived tot fix at least a part of issue #368.
I'm not 100% sure if this is okay for q2pro, but at least in my simple
tests r1q2, q2pro and now yq2 generate the same URL. Nevertheless it's
somewhat inconssistent to search generic files at /moddir/... and the
filelist at /moddir.filelist
This closes issue #370.
Until now the softrenderer calculated the fov relative to a hard coded
aspect of 4/3. That's wrong, because we're supporting arbitrary aspects
and we aren't calculating a fov but just a scaling factor to the global
fov which takes the aspect into the account.
Fix this by not taking any aspect calculations into account. BUT: While
this renders the gun with a correct perspective it's positioned much
nearer to the camera / player then in the GL renderers. The GL renderers
work around that problem by enforcing a minimal Z distance of 4 units,
which can't do because we're just calculating a scaling factor...
The r1q2 URL generator was, like everything in this game, buggy. It took
cl.gamedir into account when generating the URLs, but overlooked that it
is only set when 'gamedir != BASEDIR'. So baseq2 assets ended up with
/maps/foo.bsp and mod assets with /mod/maps/foo.bsp. q2pro fixed that
to always include the gamedir...
Work around this by refactoring the HTTP -> UDP fallback logic to be
more generic: Count the number of iterations and depending on the
iteration set the gamedir to be used by the URL generator or force
UDP downloads.
Cleaning the download queue as soon as a file finished downloading leads
in combination with only one parallel download and multiple precacher
runs to an ugly problem: The generic filelist is requested several time
which can lead to cycles. Hack around this by rembering if we already
requested it and reset set reminder as soon as the precacher finished.
Yes, I'm feeling dirty.
If the server sends us an URL with trailing slash we're generating URIs
like http://example.com//maps/foo.bsp. While double // are perfectly
valid they might me rejected by some servers. So let's play save.
While at it replace the crappy Z_TagMalloc() with the standard malloc().
Z_TagMalloc() ist just a wrapper arround malloc(), there's no functional
change.
