The quake-specific enums are now in the client header, and the particle
system now has a gravity field rather than getting it from
vid_render_data (which I hope to eventually get rid of entirely).
I think the widespread use of recalc_refdef (and force_fullscreen) was
the result of a rushed merge of the renderer and video code (I do seem
to remember sprinkling them around). This cleans the two out of the
client code.
Only CaptureBGR is per-renderer as the rest of the screenshot code uses
it to do the actual capture (which is target dependent). Vulkan is
currently broken due to capture being an asynchronous process and the
rest of the code expecting capture to be synchronous (also, bgr vs rgb).
The best thing is all renderers now write the same format (currently
png).
While there's currently only the one still, this will allow the entities
to be multiply queued for multi-pass rendering (eg, shadows). As the
avoidance of putting an entity in the same queue more than once relies
on the entity id, all entities now come from the scene (which is stored
in cl_world in the client code for nq and qw), thus the extensive
changes in the clients.
The more advanced modes are rather broken (continuous spinning), but
they may have been for a while. The bulk of the various changes were due
to renaming viewstate's origin and angles to make their meaning more
explicit.
They've been near-identical for years, now they're only one. It proved
necessary to start merging the HUD code which for now is just a few cvar
declarations (not even init), but that should be a separate set of
commits.
Handling of view angles is a little hacky at the moment, but this gets
the chase camera code and most of the common input code into one place,
which will make cleaning up the camera code much easier.
This is the bulk of the work for recording the resource pointer with
with builtin data. I don't know how much of a difference it makes for
most things, but it's probably pretty big for qwaq-curses due to the
very high number of calls to the curses builtins.
Closes#26
It's not enforced a this stage, and it would be easy enough to handle,
but it turns out all the standard quake and quakeworld progs never used
... for the print functions: the behavior of PF_VarString was
undocumented and so... tough :P.
When doing the builtin params data change, I had somehow switch
multicast's number from 82 to 81. Fortunately, another builtin is also
81, so the VM told me off when I tried to run qw-server :)
This is part of the work for #26 (Record resource pointer with builtin
function data). Currently, the data pointer gets as far as the
per-instance VM function table (I don't feel like tackling the job of
converting all the builtin functions tonight). All the builtin modules
that register a resources data block pass that block on to
PR_RegisterBuiltins.
This will make it possible for the engine to set up their parameter
pointers when running Ruamoko progs. At this stage, it doesn't matter
*too* much, except for varargs functions, because no builtin yet takes
anything larger than a float quaternion, but it will be critical when
double or long vec3 and vec4 values are passed.
nq was just a bit of whitespace, but qw had an actual bug where the
parameters were not being reset before writing to them. It really
doesn't help that I don't know where to get progs suitable for testing
(really don't what to have to write my own).
And other related fields so integer is now int (and uinteger is uint). I
really don't know why I went with integer in the first place, but this
will make using macros easier for dealing with types.
They are both gone, and pr_pointer_t is now pr_ptr_t (pointer may be a
little clearer than ptr, but ptr is consistent with things like intptr,
and keeps the type name short).
I don't know why they were ever signed (oversight at id and just
propagated?). Anyway, this resulted in "unsigned" spreading a bit, but
all to reasonable places.
This has been a long-held wishlist item, really, and I thought I might
as well take the opportunity to add the instructions. The double
versions of STATE require both the nextthink field and time global to be
double (but they're not resolved properly yet: marked with
"FIXME double time" comments).
Also, the frame number for double time state is integer rather than
float.
And partial implementations in qfcc (most places will generate an
internal error (not implemented) or segfault, but some low-hanging fruit
has already been implemented).
This renames existing VectorCompCompare (and quaternion equivalent) to
VectorCompCompareAll and makes VectorCompCompare produce a vector of
results with optional negation (converting 0,1 to 0,-1 for compatibility
with simd semantics).
The server switching levels while the client is tracking a player (at
least a server client) seems to at least temporarily clear the player
slot and thus the name value pointer becomes null. This fixes the
resulting segfault.
This is a quick way to find the client number for an entity. It returns
-1 if the entity is not a valid client (either outside the client block,
or not currently in use by a client).
After yesterday's crazy marathon editing all the particles files, and
starting to do another big change to them today, I realized that I
really do need to merge them down. All the actual spawning is now in the
client library (though particle insertion will need to be moved). GLSL
particle rendering is semi-broken in that it now does only points (until
I come up with a way to select between points and quads (probably a
context object, which I need anyway for Vulkan)).
This is needed for cleaning up excess memsets when loading files because
Hunk_RawAllocName has nonnull on its hunk pointer (as the rest of the
hunk functions really should, but not just yet).
This is actually a better solution to the renderer directly accessing
client code than provided by 7e078c7f9c.
Essentially, V_RenderView should not have been calling R_RenderView, and
CL_UpdateScreen should have been calling V_RenderView directly. The
issue was that the renderers expected the world entity model to be valid
at all times. Now, R_RenderView checks the world entity model's validity
and immediately bails if it is not, and R_ClearState (which is called
whenever the client disconnects and thus no longer has a world to
render) clears the world entity model. Thus R_RenderView can (and is)
now called unconditionally from within the renderer, simplifying
renderer-specific variants.
I think this bug has been haunting us since we introduced lerping. I do
remember chasing bad pose indices 20 years ago and never finding the
cause. I guess we never thought to check the view model.
I'm not at all happy with con_message and con_menu, but fixing them
properly will take a rework of the menus (planned, though). Also, the
Menu_ console command implementations are a bit iffy and could also do
with a rewrite (probably part of the rest of the menu rework) or just
nuking (they were part of Johnny on Flame's work, so I suspect had
something to do with joystick bindings).
This allows id1/qw config files, and to a certain extent scripts, to
work with the new binding system. It does highlight just how limited the
original system was (many keys could not bound).
Mouse axis input does not work yet as that needs a little more work to
support +strafe and +mlook.
It turns out accumulate is not really suitable now that relative axis
accumulation is done in the binding processing, and was never suitable
for absolute inputs (in this context, of course: there are contexts
where accumulate is suitable for absolute inputs).
Combining absolute and relative inputs at the binding does not work well
because absolute inputs generally update only when the physical input
updates, so clearing the axis input each frame results in a brief pulse
from the physical input, but relative inputs must be cleared each frame
(where frame here is each time the axis is read) but must accumulate the
relative updates between frames.
Other than the axis mode being incorrect, this seems to work quite
nicely.
This should be a much friendlier way of "grabbing" input, though I
suspect that using raw keyboard events will result in a keyboard grab,
which is part of the reason for wanting a friendly grab.
There does seem to be a problem with the mouse sneaking out of the
top-right and bottom-left corners. I currently suspect a bug in the X
server, but further investigation is needed.
Right now, only raw pointer motion and button events are handled, and
the mouse escapes the window, and there are some issues with focus in
focus-follows-mouse environments. However, this should be a much nicer
setup than DGA.
I have no idea why it was necessary, and certainly should not be now as
any such portability issues should be tucked away such that the client
code never sees such.
Everything is set up so default recipes work as expected (by me) for a
3Dconnexion SpaceNavigator:
translation axes move quakeguy in the direction the puck is moved
tilting the puck forward pitches forward (look down)
tilting the puck to the left rolls to the left
twisting the puck clockwise (looked at from the top) turns quakeguy
to the right.
This does mean that the default pitch motion for a regular mouse is now
push forward to pitch forward (look down) (inverted from before).
Mouse scaling is out (too small), but that's because in_amp etc are
ignored for now (thinking about how to integrate cvars with axis
recipes). Joystick input will be the same.
There's now an internal event handler for taking care of device addition
and removal, and a public event handler for dealing with device input
events in various contexts In particular, so the clients can check for
the escape key.
Saving is not so important, but for loading, while the input system
doesn't make much use of cvars at this stage, it makes sense for them to
be loaded before the input system configuration is loaded.
The mouse bound to movement axes works (though signs are all over the
place, so movement direction is a little off), and binding F10 (key 68)
to quit works :)
This has smashed the keydest handling for many things, and bindings, but
seems to be a good start with the new input system: the console in
qw-client-x11 is usable (keyboard-only).
The button and axis values have been removed from the knum_t enum as
mouse events are separate from key events, and other button and axis
inputs will be handled separately.
keys.c has been disabled in the build as it is obsolute (thus much of
the breakage).
kbutton_t is now in_button_t and has been moved to input.h. Also, a
button registration function has been added to take care of +button and
-button command creation and, eventually, direct binding of "physical"
buttons to logical buttons. "Physical" buttons are those coming in from
the OS (keyboard, mouse, joystick...), logical buttons are what the code
looks at for button state.
Additionally, the button edge detection code has been cleaned up such
that it no longer uses magic numbers, and the conversion to a float is
cleaner. Interestingly, I found that the handling is extremely
frame-rate dependent (eg, +forward will accelerate the player to full
speed much faster at 72fps than it does at 20fps). This may be a factor
in why gamers are frame rate obsessed: other games doing the same thing
would certainly feel different under varying frame rates.
For now, the functions check for a null hunk pointer and use the global
hunk (initialized via Memory_Init) if necessary. However, Hunk_Init is
available (and used by Memory_Init) to create a hunk from any arbitrary
memory block. So long as that block is 64-byte aligned, allocations
within the hunk will remain 64-byte aligned.
The fact that numleafs did not include leaf 0 actually caused in many
places due to never being sure whether to add 1. Hopefully this fixes
some of the confusion. (and that comment in sv_init didn't last long :P)
This fixes some out-by-one bugs caused by there being an obo bug in the
original SV_CalcPHS: space was being allocated for numleafs leafs, but
numleafs does not count the world-surrounding solid leaf 0, but
SV_CalcPHS generates pvs and phs data (just the "everything" set) for
leaf 0, which is later used for broadcasts and the like.
Hunk_Alloc has a rather large per-block overhead. Also, small pvs sets
(64 leafs) will fit into just the basic set structure so no need to
allocate data for the maps.
Modern maps can have many more leafs (eg, ad_tears has 98983 leafs).
Using set_t makes dynamic leaf counts easy to support and the code much
easier to read (though set_is_member and the iterators are a little
slower). The main thing to watch out for is the novis set and the set
returned by Mod_LeafPVS never shrink, and may have excess elements (ie,
indicate that nonexistent leafs are visible).
The idle scale was 114.591559 time too big (forgot both half angle for the
quaternion and converting from degrees to radians for the idle rotations).
Also, take the intermission view position and rotation direct from the
player entity, not viewstate, as while viewstate.origin is the same,
viewstate.rotation is the player's input, not the rotation set by the
server. Fixes the unlocked view angle.
The recent changes to key handling broke using escape to get out of the
console (escape would toggle between console and menu). Thus take care
of the menu (escape) part of the coupling FIXME by implementing a
callback for the escape key (and removing key_togglemenu) and sorting
out the escape key handling in console. Seems to work nicely
This sorts out the unwanted use of R_EnqueueEntity, which will help with
removing another global (r_ent_queue), which is necessary for threaded
multi-pass rendering (ie, shadows).
The renderer's LineGraph now takes a height parameter, and netgraph now
uses cl_* cvars instead of r_* (which never really made sense),
including it's own height cvar (the render graphs still use
r_graphheight).
Ping ack (A2A_ACK) is always a 1-byte packet, so check that the A2A_ACK
is the only byte in the packet before passing the packet to the server
list code. Fixes the mysterious dropped packet every 256 packets as the
low eight bits of the packet's sequence number equalled A2A_ACK.
The uptime display had not been updated for the offset Sys_DoubleTime,
so add Sys_DoubleTimeBase to make it easy to use Sys_DoubleTime as
uptime.
Line up the layout of the client list was not consistent for drop and
qport.
conwidth and conheight have been moved into vid.conview (probably change
the name at some time), and scr_vrect has been replaced by a view as
well. This makes it much easier to create 2d elements that follow the
screen size (taking advantage of a view's gravity) which will, in the
end, make changing the window size easier.
This refactors (as such) keys.c so that it no longer depends on console
or gib, and pulls keys out of video targets. The eventual plan is to
move all high-level general input handling into libQFinput, and probably
low-level (eg, /dev/input handling for joysticks etc on Linux).
