of sector objects as whole groups of points and sprite angles.
The following goals are intended to be achieved with this code:
- Make it easy to let the user toggle sector object interpolation.
- Interpolate the angles of sprites carried by sector objects.
- Use the right amount of samples for interpolating a sector object,
depending on the players' locations, as done in the checks within
DoSector. Unfortunately, modifying DoSector itself to
unconditionally call MoveSectorObjects(sop, synctics) technically
changes the way sectors move (in the logical sense), and was
found out to make a specifically constructed user map unbeatable.
- Make it easy to disable interpolation of a whole sector object in
case of a need. This is especially important if such an object
is controlled by a player in multiplayer, mostly since this
isn't compatible with the way player prediction is working.
A known issue, which also applies to existing settings like the voxel
toggle, is that its value gets written to the saved game, and when such
a game is loaded, the its value gets overwritten by the one in the
saved game. Options should move to settings.cfg later, anyway.
similar manner to what's done in Duke3D (with the addition of the angle).
There seem to be some jitters with this, mostly in Master/Slave mode.
Decreasing PAKRATE in mmulti.cpp might also increase the frequency
of this occuring in Peer-2-Peer mode.
less dependent on the frame rate.
It would probably be better to update this from the game loop side,
like in Duke3D, but it's still better than the preceding situation.
DoPlayerTurn/DoPlayerHorizon while input is tied to the frame rate:
Introduce the new player flags PF2_INPUT_CAN_TURN and PF2_INPUT_CAN_AIM.
Set PF2_INPUT_CAN_TURN if DoPlayerTurn can be called outside
of getinput. Similarly set PF2_INPUT_CAN_AIM if DoPlayerHorizon
can be called in this manner.
getinput will only call DoPlayerTurn/DoPlayerHorizon
if PF2_INPUT_CAN_TURN/PF2_INPUT_CAN_AIM is set. These flags are reset
right before the call to the player's current DoPlayerAction function.
For one example in which this assists, it's not always the
case that DoPlayerDeathFollowKiller may call DoPlayerTurn,
even if we assume that pp->input.q16angvel is never zero.
This fixes truncations of q16ang in MovePlayer. One known
fixed issue is a minor micro-shaking effect, reproduced
while standing on a non-moving SO (e.g., the bus in level 1).
The latter is also related to the use of camq16ang.
Based in idea on patch from mjr4077au.
is non-null seems to resolve the newly introduced interpolation
issue for looking up/down while controlling a sector object.
We can also remove the PF_DEAD test, since
game.cpp:getinput should lock any kind of aiming.
src/src/game.cpp:getinput: We now, however, need to further
lock turning here while controlling a sector object.
sector. This re-introduces the angle interpolation in drawscreen
while sector object interpolation is in use.
A side-effect of this is that looking up/down is now less smooth
while controlling a sector object (e.g., a turret).
PACKED macro. This is more consistent with the current Duke3D codebase,
and further fixes build with older versions of MinGW GCC, in which
attribute packed is broken without specifying -mno-ms-bitfields.
draw.cpp: Fix the lack of interpolation while walking on a sector
object, like the bus roof or the floor of the train in Seppuku Station.
track.cpp: Make sure the player's location and angle aren't mistakenly
interpolated while standing on a moving sector object as a consequence.
While it is understandable that avel and horz came from Duke3D,
having both q16horiz and q16horz in the updated SW_PACKET struct
can be confusing, and the alternative notation is more consistent
with the original struct field names of angvel and aimvel, as well
as the differing uses of the name angvel still present in player.cpp.
for them to modify the player's camq16ang/camq16horiz field
instead of q16ang/q16horiz. Additionally, pass to them the
change in angle/horiz via a parameter, as an alternative
to direct access to the corresponding player input field.
Add the camq16ang and camq16horiz fields to the player struct.
With the exception of DoPlayerTurn and DoPlayerHorizon, whenever
code in player.cpp updates player's q16ang/q16horiz, also write
the updated values to camq16ang/camq16horiz. These variables'
preceding values are never used in these functions.
related to the definitions of RANDOM_NEG in bunny.cpp, ripper.cpp
and ripper2.cpp. Do so in a way that isn't re-introducing compiler
warnings. This partially fixes compatibility with demos made for SW 1.2.
Additionally, replace the 3 separate definitions of RANDOM_NEG
with a common one within game.h.

This reverts commit 31eb55c1fa.
- Define new boolean 'on_vehicle' in PLAYERp struct for use with interpolating while on vehicle and other checks.
- Move horizon code back into separate DoPlayerHorizon() function. Adjusting horizon while in vehicle must come at the end of the DoPlayerOperate*() function.
- Make DoPlayerHorizon() accessible in game.cpp.
- Change code in DoPlayerHorizon() to process according how 'pp->on_vehicle' is set.
- Make scaleAdjustmentToInterval available outside of getinput().
- Don't process input at frame-rate while on a vehicle. Vehicle code is too difficult to process outside of the game's clock.
Partially based on NY00123's upstream implementation of tying player input to frame-rate.
What 43ec16eb55 intends to do was already done via 2d73466425, however I applied the if statement in the opposite order so when it was cherry-picked again, the pathway was actually reversed - interpolating when alive and not when dead.
Rather than re-apply the opposite order, I've made the if statement match upstream for more consistency and to avoid further conflicts.
Let's see if this is breaking anything.

- Inline function returns a double, therefore we should use it and not potentially truncate the mantissa.
- Use divisors to get true numbers of some floats (3.333 -> 10/3, etc).
- Remove a few brackets/parentheses where possible from what are already exceedingly bracketed lines.
