This involved disabling sigils for hipnotic and rogue (not used),
adjusting the number of items views, and moving the two keys views for
hipnotic. Rogue is not yet using the correct status bar pics.
The functionality of the hipnotic and rogue weapon power-ups is now done
by a various mappings instead of separate functions. In theory, this
should make things more flexible, but most importantly, there's a lot
less code duplication.
Sigils can't be flashed as they don't have any animations provided, and
they're not normally as critical. I don't know why items weren't
flashed, but since the pics are there, might as well use them (and the
flashing keys do look pretty good).
I think this makes the purpose of the functions more clear and makes the
protocol logic less dependent on the meaning of some of the updates.
Most of the update functions are not fully implemented yet.
I had forgotten that the cl structs in nq and qw were different layouts,
which resulted in qw's sbar/hud being quite broken. Rather than messing
with the structs, I decided it would be far better in the long run to
clean up sbar's access to the cl struct and the few other nq/qw specific
globals it used. There are still plenty of bugs to fix, but now almost
everything is in the one place.
This includes moving the related cvars from botn nq and qw into the
client hud code. In addition, the hud code supports update and
update-once function components. The update component is for updates
that occur every frame, but update-once components (not used yet) are
for one-shot updates (eg, when a value updates very infrequently).
Much of the nq/qw HUD system is quite broken, but the basic status bar
seems to be working nicely. As is the console (both client and server).
Possibly the biggest benefit is separating the rendering of HUD elements
from the updating of them, and much less traversing of invisible views
whose only purpose is to control the positioning of the visible views.
The view flow tests are currently disabled until I adapt the flow code
to ECS.
There seems to be a problem with view resizing in that some gravities
don't follow resizing correctly.
While the libraries are probably getting a little out of hand, the
separation into its own directory is probably a good thing as an ECS
should not be tied to scenes. This should make the ECS more generally
useful.
This puts the hierarchy (transform) reference, animation, visibility,
renderer, active, and old_origin data in separate components. There are
a few bugs (crashes on grenade explosions in gl/glsl/vulkan, immediately
in sw, reasons known, missing brush models in vulkan).
While quake doesn't really need an ECS, the direction I want to take QF
does, and it does seem to have improved memory bandwidth a little
(uncertain). However, there's a lot more work to go (especially fixing
the above bugs), but this seems to be a good start.
The pitch cvars are taken from quakespasm because I ran into a button I
couldn't shoot with the 80 degree limit, but I figured I'd add roll
limits while I was at it.
I really don't know why I tried to do ring-buffers without gaps, the
code complication is just not worth the tiny savings in memory. In fact,
just the switch from pointers to 32-bit offsets saves more memory than
not having gaps (on 64-bit systems, no change on 32-bit).
Due to the mis-initialization of the union used to parse the color
vector, the intensity was incorrectly set to zero and thus the light
dropped, meaning that all lights in ad_tears were lost.
This gets ambient sounds (in particular, water and sky) working again
for quakeworld after the recent sound changes, and again for nq after I
don't know how long.
This is a particularly ancient bug, sort of introduced by rhamph when he
optimized temp entity model handling and later exacerbated by me.
However, I suspect the actual problem is limited to nq as qw's gamedir
handling would have caused the models to be reloaded, but nq doesn't
ever change game directories once running.
Moving the negation into the calculation of the sun angle prevents -0
getting into the vector (not that it makes much difference other than
minor confusion when reading the light data).
Maps specify sunlight as shining in a specific direction, but the
lighting system wants the direction to the sun as it's used directly in
shading calculations. Direction correctness confirmed by disabling other
lights and checking marcher's outside scene (ensuring the flat ground
was lit). As a bonus, I've finally confirmed I actually have the skybox
in the correct orientation (sunlight vector more or less matched the
position of the sun in marcher's sky).
Abyss of Pandemonium uses global ambient light a lot, but doesn't
specify it in every map (nothing extracting entities and adding a
reasonable value can't fix). I imagine some further tweaking will be
needed.
The parsing of light data from maps is now in the client library, and
basic light management is in scene. Putting the light loading code into
the Vulkan renderer was a mistake I've wanted to correct for a while.
The client code still needs a bit of cleanup, but the basics are working
nicely.
This replaces *_NewMap with *_NewScene and adds SCR_NewScene to handle
loading a new map (for quake) in the renderer, and will eventually be
how any new scene is loaded.
And use it for hud_scoreboard_gravity. Putting the enum def in view made
the most sense as view does own the base type and the enum is likely to
be by useful for other settings.
This is an extremely extensive patch as it hits every cvar, and every
usage of the cvars. Cvars no longer store the value they control,
instead, they use a cexpr value object to reference the value and
specify the value's type (currently, a null type is used for strings).
Non-string cvars are passed through cexpr, allowing expressions in the
cvars' settings. Also, cvars have returned to an enhanced version of the
original (id quake) registration scheme.
As a minor benefit, relevant code having direct access to the
cvar-controlled variables is probably a slight optimization as it
removed a pointer dereference, and the variables can be located for data
locality.
The static cvar descriptors are made private as an additional safety
layer, though there's nothing stopping external modification via
Cvar_FindVar (which is needed for adding listeners).
While not used yet (partly due to working out the design), cvars can
have a validation function.
Registering a cvar allows a primary listener (and its data) to be
specified: it will always be called first when the cvar is modified. The
combination of proper listeners and direct access to the controlled
variable greatly simplifies the more complex cvar interactions as much
less null checking is required, and there's no need for one cvar's
callback to call another's.
nq-x11 is known to work at least well enough for the demos. More testing
will come.
It seems clang defaults to unsigned for enums. Interestingly, gcc was ok
with the checks being either way. I guess gcc treats enums that *can* be
unsigned as DWIM.
Still work with gcc, of course, and I still need to fix them properly,
but now they're actually slightly easier to find as they all have vec_t
and FIXME on the same line.
I meant to do this a while ago but forgot about it. Things are a bit of
a mess in that the renderer knows too much about entities, but
eventually the renderer will know about only things to render (meshes,
particles, etc).
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.
