While the word-level text objects aren't used (because standard center
print messages are already flowed as such), using a passage object makes
dealing with the lines and incremental printing quite easy and
efficient (everything is counted just the once or twice, not every frame).
The text object covering the whole passage was not being initialized,
thus center print tried to print rubbish when (incorrectly) printing the
entire message.
Most of the update functions are scheduled by Sbar_Changed() using
tables to determine what update functions need to be called for which
view entities. As hud_updateonce is called, and an entity can have only
one of any component, this becomes a set of updates to call when during
hud/sbar rendering.
I'm not particularly happy with the way onresize is handled, but at this
stage a better way of dealing with resizing views and getting the child
views to flow correctly hasn't come to mind. However, the system should
at least be usable.
I'm not sure when things broke on my laptop (I thought I got warp and
fisheye working on my laptop), but it turns out things weren't quite
right, thus warp (and presumably fisheye) weren't working properly due
to GLSL errors that I only just noticed. This fixes water warp (and
probably fisheye).
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).
Now only the time portion updates every frame, and then only when the
scores are shown (no real change for that one). Not really a significant
optimization, as the information was updated only while the scores were
shown, but it's still nice.
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.
As the bookkeeping data is spread between three arrays, sorting a
component pool is not trivial and thus not something to duplicate around
the codebase.
It doesn't check that the entity itself is valid, but it does at least
check that the index fetched from the sparse array is valid. Fixes a
segfault when a valid entity never had the component.
It's not quite complete in that entities need to be created for the
objects, and passage text object might get additional components in the
hierarchy, but the direct use of views has been replaced by the use of a
hierarchy object with the same tree structure, and now has text objects
for paragraphs and the entire passage.
As an implementation detail, inserting null hierarchies (src hierarchy
is null) is supported for ease of hierarchy construction from data. No
component data is copied, only the child and parent indices and counts
are updated.
The resource functions assume the requested layers is correct (really,
the lighting code assumes that the resource functions assume such), but
QFV_CreateImage multiplies the layer count by 6 for cube maps (really,
the issue is in QFV_CreateImage, but I want to move away from it
anyway).
The check for the entity being the view model was checking only the
view model id, which is not sufficient when the view model is invalid by
never being set to other than 0s. A better system for dealing with the
view model is needed.
Another step towards moving all resource creation into the one place.
The motivation for doing the change was getting my test scene to work
with only ambient lights or no lights at all.
It seems this isn't needed any more (not sure why) as both glsl and
vulkan are happy without it. Also unsure why moving to ECS made gl and
sw change behavior regarding rendering the test models in my scene.
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 fixes the segfault due to the world entity not actually existing,
without adding a world entity. It takes advantage of the ECS in that the
edge renderer needs only the world matrix, brush model pointer, and the
animation frame number (which is just 0/1 for brush models), thus the
inherent SOA of ECS helps out, though benchmarking is needed to see if
it made any real difference.
With this, all 4 renderers are working again.
Since entity_t has a pointer to the registry owning the entity, there's
no need to access a global to get at the registry. Also move component
getting closer to where it's used.
It no longer initializes the new component. For that, use
Ent_SetComponent which will copy in the provided data or call the
component's create function if the data pointer is null (in which case,
Ent_SetComponent acts as Ent_SetComponent used to).
