1. Timing and Changes
|
|
---------------------
|
|
The current UQM timer runs on a 120 ticks/second clock, defined by the
|
|
constant ONE_SECOND (in timelib.h). Theoretically, all code has been
|
|
updated to use this constant where needed, so the timer precision can
|
|
be increased to 1000, for example, to match the native SDL timer
|
|
resolution.
|
|
|
|
The following functions and all variables and constants used with them
|
|
have been examined and patched where necessary.
|
|
|
|
Functions that have something to do with time:
|
|
XFormColorMap
|
|
XFormPLUT
|
|
CycleColorMap
|
|
FadeMusic
|
|
SeedRandomNumbers
|
|
WaitForNoInput
|
|
GetTimeCounter
|
|
SleepThread
|
|
SleepThreadUntil
|
|
|
|
Global vars:
|
|
GameClock
|
|
|
|
Constants changed:
|
|
BATTLE_FRAME_RATE (element.h)
|
|
NUM_DELAYS (clock.c)
|
|
ACCELERATION_INCREMENT (gameinp.c)
|
|
IP_FRAME_RATE (solarsys.c)
|
|
|
|
Constants added:
|
|
CLOCK_BASE_FRAMERATE (clock.c)
|
|
STEP_ACCEL_DELAY (pstarmap.c)
|
|
PLANET_SIDE_RATE (lander.c)
|
|
|
|
All alien comm animation definitions (frame rates) were patched to take
|
|
ONE_SECOND into account. So if some animations start to bug all of a
|
|
sudden, you know where to look ;).
|
|
|
|
The game-clock function SetGameClockRate() changed to use the rate
|
|
defined by CLOCK_BASE_FRAMERATE and does not use ONE_SECOND now (and is
|
|
not supposed to).
|
|
|
|
|
|
2. Possible Rate Changes
|
|
------------------------
|
|
The PLANET_SIDE_RATE and IP_FRAME_RATE can be safely adjusted at this
|
|
time. The BATTLE_FRAME_RATE needs more work.
|
|
|
|
|
|
3. Battle rate
|
|
--------------
|
|
The BATTLE_FRAME_RATE constant (currently 24 fps) can be adjusted only
|
|
after converting the rate counters for all ships used in melee. They
|
|
are expressed in frames and *must* take BATTLE_FRAME_RATE into account.
|
|
|
|
They are:
|
|
ENERGY_WAIT
|
|
TURN_WAIT
|
|
THRUST_WAIT
|
|
WEAPON_WAIT
|
|
SPECIAL_WAIT
|
|
|
|
There is probably more that needs to be done to make it work properly
|
|
with an altered BATTLE_FRAME_RATE. Expect more info to appear.
