Because demoplayback seen by the shared client code is in viewstate and
that's in cl, it gets set to 0 when connecting, thus the network icon
while playing demos.
With the hierarchy code fixed for intra-hierarchy parenting, there's no
longer any need to first pull the sub-hierarchy out of the main
hierarchy before changing the parent, resulting in less memory churn.
In the end, it was removal of the old entries that corrupted the parent
indices. Very nicely, most of the fixes involved removing code. Taking
advantage of the ECS to debug the hierarchies was fun, and the resulting
colorized entity names helped no end.
Even 37 objects is a lot, but it's a whole lot better than 180. Most
importantly, it reproduces the problem, which seems to be not all parent
indices getting updated. The child indices seem to be working nice, as
do the reference object indices (ie, the entity components). I suspect
its the parent indices getting corrupted that cause problems on the
second switch of the hud/sbar cvar as the parent indices are used to
find the child indices that need to be updated.
This improves the behavior of hierarchies when self-inserting, but nq's
sbar still crashes when trying to do so. However, its tree is a fair bit
more complex than the test case (that does pass now), so I need to try
to replicate the important parts of the tree with fewer objects (180 is
too many to work with).
As expected, reparenting a sub-hierarchy such that it (and possibly its
children) move up the arrays fails (this is why sbar needs to first
remove the sub-hierarchy then insert it).
Since test_build_hierarchy2 already tested removal of a sub-hierarchy
(once fixed), it seems test_build_hierarchy3 testing parenting within
the same hierarchy would be a good idea. Reparenting such that
everything moves to later in the arrays works nicely (not very
surprising).
Setting the parent to another object in the same hierarchy still causes
a segfault (worked around for now), but the mangled views were caused by
View_UpdateHierarchy not being called prior to the first call to
set_hud_sbar (why, though? I suspect something to do with oldlen). And
ECS_SortComponentPool finally gets used to ensure the sbar panels are
behind the info pics.
Its updates to the various indices were out, but this was missed due to
the tests being wrong. I wonder if I got interrupted while working on
them last and just assumed the removals were correct. This improves
sbar's behavior, but it's still wrong when pulling the armory view out
of the inventory. Very unsure what's going on, but the various indices
look ok, as do the view positions.
Ugh, things were quite bad, it turns out. It seems a lot of trouble
would have been saved if these tests had worked (however, something is
still not quite right as views are out of place).
This is the bug that sbar found when pulling a sub-hierarchy out of a
larger hierarchy: child indices not getting updated correctly for later
siblings and any niece objects.
The hierarchy-specific tests from the transform tests have been moved
into the ecs tests and the transform tests renamed appropriately. As
part of the process, hierarchies can now have a null type (ie, no
additional components maintained by the hierarchy). This should make
sorting out the issues highlighted by sbar a bit easier.
It should have always been here, but when I first created the hierarchy
and transform objects, I didn't know where things would go. Having two
chunks of code for setting an entity's parent was too already too much,
and I expect to have other hierarchy types. Doesn't fix the issues
encountered with sbar, of course.
Frags, minifrags and miniteam now work (mostly, the auto-switching
between them is not working yet). Switching between hud and sbar is
mostly working, except for some problems with the hierarchies corrupting
themselves: setting the parent of an object to another object in the
same hierarchy is just completely broken, and working with complex
hierarchies seems to mess up something (things getting out of phase). I
guess my unit tests were too simple.
For nq, all that remains is the various overlays (death-match,
intermission and finale) and rogue and hipnotic specific updates.
Fortunately, other than the death-match overlay, qw is just a subset of
nq for the hud (and even then, I imagine the info in qw would be nice in
nq).
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.
