This is the first step towards component-based entities.
There's still some transform-related stuff in the struct that needs to
be moved, but it's all entirely client related (rather than renderer)
and will probably go into a "client" component. Also, the current
components are directly included structs rather than references as I
didn't want to deal with the object management at this stage.
As part of the process (because transforms use simd) this also starts
the process of moving QF to using simd for vectors and matrices. There's
now a mess of simd and sisd code mixed together, but it works
surprisingly well together.
This is a big step towards a cleaner api. The struct reference in
model_t really should be a pointer, but bsp submodel(?) loading messed
that up, though that's just a matter of taking more care in the loading
code. It seems sensible to make that a separate step.
It now takes a context pointer (opaque data) that holds the buffers it
uses for the temporary strings. If the context pointer is null, a static
context is used (making those uses of va NOT thread-safe). Most calls to
va use the static context, but all such calls have been formatted
consistently so they are easy to find when it comes time to do a full
audit.
There's still some cleanup to do, but everything seems to be working
nicely: `make -j` works, `make distcheck` passes. There is probably
plenty of bitrot in the package directories (RPM, debian), though.
The vc project files have been removed since those versions are way out
of date and quakeforge is pretty much dependent on gcc now anyway.
Most of the old Makefile.am files are now Makemodule.am. This should
allow for new Makefile.am files that allow local building (to be added
on an as-needed bases). The current remaining Makefile.am files are for
standalone sub-projects.a
The installable bins are currently built in the top-level build
directory. This may change if the clutter gets to be too much.
While this does make a noticeable difference in build times, the main
reason for the switch was to take care of the growing dependency issues:
now it's possible to build tools for code generation (eg, using qfcc and
ruamoko programs for code-gen).
They take a pointer to a free-list used for hashlinks so the hashlink
pools can be per-thread. However, hash tables that are not updated are
always thread-safe, so this affects only updates. progs_t has been set
up such that it is easy for multiple progs within one thread can share
hashlinks.
It is now set to 0 when progs are loaded and every time
PR_ExecuteProgram() returns. This takes care of the default case, but
when setting parameters, pr_argc needs to be set correctly in case a
vararg function is called.
Only as scalars, I still need to think about what to do for vectors and
quaternions due to param size issues. Also, doubles are not yet
guaranteed to be correctly aligned.
I added Sys_RegisterShutdown years ago and never really did anything
with it: now any system that needs to be shutdown can ensure it gets
shutdown on program exit, and in the correct order (ie, reverse to init
order).
I've decided that setting pr.max_edicts and pr.zone_size as part of the
local progs initialization rather than in PR_LoadProgsFile makes more
sense. For one, it is unlikely for the limits to change every time progs is
reloaded. Also, they seem to be a property of the VM rather than the progs.
However, there is nothing stopping the caller from updating max_edicts and
zone_size every call.
While scan-build wasn't what I was looking for, it has proven useful
anyway: many of the sizeof errors were just noise, but a few were actual
bugs (allocating too much or too little memory).
The search for these files will stop in the vpath that contains the .bsp
file to which they belong. This will prevent problems with
id1/maps/start.lit being used for shadows/maps/start.bsp.
The data needed for the checks has been gone from QF for a very long time
(since Jan 2000), and good riddance to it, really: I suspect it's in
violation of id's copyright on the game data (ok, it might be fair use, but
still...).
Something is funny with Ubuntu such that -ldl needs to be specifically
added even though QFutil's .la specifies it. I don't know if it's a libtool
issue or not, but this does work.
More will probably be necessary, but this was sufficient to get prover to
the point where qfcc segged building qwaq (0.7.2).
Now the user can create and destroy IMTs at will, though currently
destroying IMTs is currently all or nothing (imt_drop_all).
An IMT is created via imt_create which takes the keydest name (key_game
etc), the name of the IMT (must be unique for all IMTs) and optionally the
name of the IMT to which the key binding search will fall back if there is
no binding in the current IMT, but must be already defined and on the same
keydest. This means that IMTs now have user determined fallback paths. The
requirements for the fallback IMT prevent loops and other weird behaviour.
Actual key binding via in_bind is unaffected. This is why the IMT name must
be unique across all IMTs.
The "imt" command works with the key_game keydest, but imt_keydest is
provided for specifying the active IMT for a specific keydest.
At startup, default IMTs are setup to emulate the previous static IMTs so
old configs will continue to work (mostly). New config files will be
written with commands to drop all of the current IMTs and build new ones,
with the bindings and active IMT set as well.
This fixes the flickering status bar for those renderers that use
scr_copyeverything correctly. sw and sw32. glsl flukes out by not touching
scr_copyeverything and gl is wrong by always clearing it to 0 and never
setting it later.
The cshift is now drawn before centerprint, console and the loading plaque.
Unfortunately, due to something odd going on, the sbar stuff is drawn by
the console rather than by Sbar_Draw :P.
This fixes the infinite loop in Sock's shadows mode. Thanks to Spike for
helping me with what should be happening. However, we're still uncertain
about just how the thinktime/sv.time logic should behave.
It turns out gcc has a way to force functions to inline even when it thinks
doing so would not be a good idea (call to a modest sized function unlikely).
When trying to get the client ent num from an entity's owner, it helps if
the owner field is used :P Fixes a segfault firing nails (and sometimes
rockets) in freewill's coop mod. Hopefully fixes his "trigger in clipping
list" bug.
Note that this is only a soft-limit and prevents excessive beams when only
one is expected. If more beams are desirned, just use 0 for the entity
number.
Really, when cl_nodelta is in effect (eg, .qwd demo recording and thus
playback). QW now uses the new shared entity state block as I'd intended.
Thanks to the cleanup of ghost entities (ie, entities that have been
removed but continue to be rendered), glsl overkill has gone from 157 to
163 fps :)
td_lastframe needs to be a float in qw. It seems the meaning changed from
nq to qw, but that's rather bogus. I need to look further into juat what's
going on, but at least now timedemo works.
Caused by an out-by-one error thanks to the insane way the sound list is
built. Came about when doing the model/sound list sanitation during the
GLSL project, but this one was sneakier as it resulted only in a missing
sound rather than a segfault.
CL_StopPlayback was incorrectly calling Key_SetKeyDest with key_game. As
CL_SetState calls Key_SetKeyDest with the appropriate parameter,
CL_StopPlayback calling Key_SetKeyDest is actually redundate, so just
change key_game_target back to IMT_0.
I guess it's just part of how qizmo works, but a few extra packets get into
the demo before the packet with the serverdata svc :/ More checking needs
to be done (only the initial connect packet is checked), but this works for
now.
NQ's client-side onground now works similarly to QW's: -1 = not on ground,
0+ = on ground (plane num?) but only 0 is used in NQ as the necessary
information is not sent over the network.
For certain values of "fix" ;). Both are brought back to life but
idealpitch is never set (always 0) and veiwheight is set in V_RenderView().
However, this brings the rest of the code in cl_view.c just that little bit
closer to merged :)
When the stufftext buffering was implemented, we forgot about
svc_serverdata...
While nq might normally not have the issue, I thought it best to implement
in nq, too.
I didn't like the way client/server code was poking around at the
implementation. Instead, provide a couple of accessor functions for the
same information.
nq now rejects anything that doesn't look like a .dem, and qw not only
rejects anything that looks like neither a .qwd nor a .mvd, but even
detects which one is being played by the contents rather than the file name
(foo.mvd.gz would be mis-detected as a qwd!!).
The change to nq SV_RunThink to match that in qw finally bit my bum. I
suspect it's really a bug in the honey progs (using ltime on a non-pusher),
but QF locking up is not very friendly. I want to keep the option of having
a think loop in the same frame for progs that expect it (using
self.nextthink = time), but also NQ's original method of running think
every frame. Hopefully no progs expect "self.nextthink = time" to run
every frame rather than loop within the current frame.
Now it doesn't matter if you get 22 fps or 72, you jump the same height,
which actually happens to be slightly higher than the previous 72fps jump.
Effectively, you jump the height you would if you got infinite fps ;)
One's an actual bug, the other a bit of error checking (not sure how
necessary it is, but it's in code that we don't /want/ to run, so it can't
hurt :)
The renderer now gets initialized and things sort of work (qw-client will
idle, though nothing is displayed). However, as the viddef stuff is broken,
it segs on trying to run the overkill demo.
Still, nothing will work: no plugins are loaded and they're all broken
anyway.
glx, sgl, glslx etc are going away, just the basics will be built: fbdev
(probably go away eventually), sdl, x11 and hopefully someday win. That's
actually the only reason anything links.
Just about to do a release, and I realized windows users wouldn't have any
way of checking out the new renderer. I'll add wglsl when I get a chance to
do some testing.
o All instances of LIBADD/LDADD have a corresponding DEPENDENCIES
specificatiion.
o libraries now use a lib_ldflags macro to keep things consistent
o duplication of source/lib names has been minimized (particularly in
the libraries; more work needs to be done for the executables)
o automake spec blocks have been organized (again, more work needs to be
done for the executables)
Most subsystems that depend on other subsystems now call the init functions
themselves. This makes for much cleaner client initialization (more work
needs to be done for the server).
The renderer should now be free of any direct access to client code. Even
3d rendering is now done via a function pointer.
The cshift code is done as a 2d screen function.
This seems to have been an optimization for QW since standard qw removed
monsters. However, since there are QW mods that brought back monsters,
this should be an improvement.
This has several benifits:
o The silly issue with alias model pitches being backwards is kept out
of the renderer (it's a quakec thing: entites do their pitch
backwards, but originally, only alias models were rotated. Hipnotic
did brush entity rotations in the correct direction).
o Angle to frame vector conversions are done only when the entity's
angles vector changes, rather than every frame. This avoids a lot of
unnecessary trig function calls.
o Once transformed, an entity's frame vectors are always available.
However, the vectors are left handed rather than right handed (ie,
forward/left/up instead of forward/right/up): just a matter of
watching the sign. This avoids even more trig calls (flag models in
qw).
o This paves the way for merging brush entity surface rendering with the
world model surface rendering (the actual goal of this patch).
o This also paves the way for using quaternions to represent entity
orientation, as that would be a protocol change.
After discussing things with Spike of FTE, it seems that not many clients
handle zero length mvd packets particularly well. While it the skip code
might be useful for qtv, getting the packets into one but not the other
seems to be not worth the effort at this stage.
There are some problems with menus and the console messing up the key_dest
state (they assume console/menu or game, nothing else), but otherwise
things seem to work.
I got rather tired of there being multiple definitions of mostly compatible
plane types (and I need a common type anyway). dplane_t still exists for
now because I want to be careful when messing with the actual bsp format.
Same as the rotating entities in NQ. Unfortunately, I have some problems
with certain entities doing really weird things during collisions. I'll
sort that out later.
It seems that QW already allowed explode-box jumping, but this makes code a
little more consistent. Still need to figure out what to do about the
player physics code: the client prediction is wrong, though the server gets
it right (before the change).
This also makes functionality consistent across the platforms, such as
adding support for -dedicated to sdl based nq, and various timing
calculations are now consistent.
As part of the work on getting nq to work on multi-homed nodes, I used the
existing recvmsg code in qw-master to check how things work. I figured it
might be worth keeping.
