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.
Since we clip the world properly even with skyboxes active, and the
'skybox' serverinfo doesn't do anything in any other engine I know of,
nuke the 'skybox' serverinfo entirely and use a nice short semi-standard
name ("sky") for the serverinfo containing the map's preferred skybox
(as potentially modified by the .ent file on the server).
This ensures that the map's sky is always used unless the client itself has
set its r_skyname cvar. The server's r_skyname cvar is now the default
name for the skybox for when the map does not specify one. The map's sky
worldspawn field overrides this. The r_skyname cvar is no longer a
serverinfo cvar.
in_dga -> 0 (until X is fixed)
gl_multitexture -> 1 (why was this 0? not enough support back then?)
cl_usleep -> 1 (seems to be ok)
host_mem_size -> 40 (even 32 isn't enough these days)
rate -> 10000 (we're not in the modem era any more)
cl_mem_size -> 32 (16 is not enough, 32 sounds better than 24)
nq's SV_CheckVelocity will be a little different (spherical rather than
cubical), but sv_maxvelocity defaults high enough for it to not matter to
most players. It might even improve play.
The remaining differences need some careful thought before the physics
merge is done.
This allows the pvs to be used on an antity no matter how many leafs the
entity is touching. Seems to work nicely, but it will leak memory every
time a map is loaded.
This reverts commit 10232acdfe.
The problem was really in the trace code, but it got fixed by "accident"
when I had similar problems in hipnotic a couple of years later. Now to
figure out just what the trace could really should be doing.
The efrags system's usage of ent->visframe clashes with that of
CL_LinkPacketEntities. As the latter is rather bogus, and potentially
visible entities are always inserted into the map (causing ent->efrag to be
non-null), a null ent->efrag is a good indication that the entity is newly
visible.
While reading the code, I noticed the comment stating that qw projectiles
(nails) are really temp entities, so I decided to make that true. The
client now supports unlimited projectiles.
Trying to cover very long times will probably cause more problems than it
fixes, so limit the length of time. Two seconds aught to be enough for
now. Need to look into proper handling of prevtime.
