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.

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.
While loading a savegame the global edict arrays is free()ed and newly
malloc()ed to reset all entity states. When the game puts the first
client into the server it sends it's entity state to us, so as long as
there's only one client everything's okay. But when there're more
clients the entity states if all clients >1 are dangeling. Hack around
that by reconnecting the clients >1 entity states "manually".
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...
This fixed bug #357 - the problem was that
client->resp.coop_respawn.weapon and .lastweapon (pointers to gitem)
were not properly initialized when loading a savegame.
Now those fields are saved (=> we had to bump the savegame version)
and for old savegames client->resp.coop_rewspawn is initialized
from client->pers, as a hack for backwards-compatibility.
Until now the UDP download code prohibited downloading of maps from all
pak files. That was some kind of copy protection, without the limitation
demo users could download assets from the full version. Don't apply that
protection for all paks, but only for numbered .pak files.
This could be enhanced by limiting the protection to pak0 to pak2 for
baseq2 and pak0 for both xatrix and rogue.
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.
This looks easy, but is rather hacky... Downloading is implemented
through the precacher. The server sends an asset list, while loading
the map another one is generated. CL_RequestNextDownload() goes
through this list, in the order models / maps -> sounds -> images,
calls CL_CheckOrDownloadFile() for each file. CL_CheckOrDownloadFile()
checks if the file is already there, return true if it is and false
if not. If the return code is false CL_RequestNextDownload() itself
returns, it's called again by CL_ParseDownload() as soon as the just
queued file finished downloading. This way all missing files are
downloaded one after the other, when CL_RequestNextDownload() finally
reaches it's end (all files are there) it send 'begin' to the server,
thus putting the client into the game.
HTTP downloads are parallel, so CL_RequestNextDownload() cannot track
which files are there and which are missing. The work around for that is
to queue the file but have CL_CheckOrDownloadFile() return true. So
CL_RequestNextDownload() thinks the file is already there, continues
with the next one, until all missing files are queued. After that it
polls CL_PendingHTTPDownloads() and sends the 'begin' as soon as all
HTTP downloads are finished.
If a HTTP download fails we cannot just queue it as UDP download,
because the precacher things that the file is already there. And we
can't tell the precacher that it's not because the precacher tracks
files only by the number of downloaded files per asste type and not
their name. Just decreasing the number of downloaded files isn't
possible since the precacher may have progressed to the next asset
type.
So: On the HTTP side it's tracked if there was an error or not. After
CL_RequestNextDownload() has queued all files and waited for all HTTP
downloads to finish it checks the HTTP error status. If there was an
error the precacher state is reset and CL_RequestNextDownload() recurses
into itself to take another run. All files that couldn't be downloaded
are queued again, this time as UDP downloads.
