* Measure afterburner cooldowns on the mission clock
afterburners_start()/afterburners_stop() timed the +Aburn Cooldown Time delay and
the player's 1.3 s re-engage delay with timer_get_milliseconds(), the real
clock. Under time compression a cooldown therefore lasted longer in mission
time than the table says, and it kept running while the game was paused. The
cooldown was added in 2020 and reused the retail re-engage check's real-clock
"now"; the rest of the file (ABURN_DECAY_TIME, the sound timers) already uses
mission timestamps.
Both delays now use the mission clock. The mission clock does not run outside
missions, so it can still be near zero when the first mission of a session
starts; the "last stopped" and "last started" times therefore start out
invalid instead of 0, so that no delay is in effect before the afterburner has
been used.
Without time compression or pausing, the delays behave as before.
* Drop stale afterburner comment and use fl2i for the cooldown cast
The comment described an earlier startup state rather than the current
behavior. fl2i is the project's float-to-int macro and truncates the same
way the old C-style cast did.
* Remove the remaining afterburner cooldown comment
Timestamps running on mission time is the common case, so it doesn't
need a comment.
Two updates to the energy transfer system.
1. Previously, for fighters missing a system (e.g. shields), the energy would be treated as if all energy from that system was routed to the other systems. So, for example, a fighter's typical speed would be faster without shields than with shields. A new AI profile flag now treats the other systems as if the energy had not been transferred.
2. At some point in development, Volition intended the `$Power Output` ships.tbl field to affect ETS. A new AI profile flag now treats the power output as a factor of energy applied to energy systems.
* Add Animation Instance Flags
* Add SEXP barebones
* Unify and simplify animation parsing
* Clean up animation calling and use new animationlist api
* Add missing break
The previous system was kind of hacky and made things a bit inflexible.
This improves that system quite a bit and also adds unit tests for the
hook variable functionality.
This maintains the type information which can be used for enforce
const-correctness and also for implementing more advanced ways of
handling the type information.
This is similar to the other changes I already posted. Here the sound
instance handles are converted to their own handle type which will make
it easier to use the sound API.
This adds a new class which allows to create type safe resource handle
types. At the moment, the engine uses ints pretty much everywhere for
providing handles to resources created by the specific subsystems. Since
all ints are the same to the C/C++ typesystem it is perfectly legal to
pass a sound handle to the graphics API as a buffer handle which will
obviously cause issues.
This adds a new type called "ID" which is a wrapper class for a generic
handle but with added type safety. An instance of this class cannot be
passed to a function expecting another type of handle which provided
compile-time type safety for these APIs.
As an initial test I converted the game sound handles to this new type.
I already found a bug in the mainhall system thanks to this new type.
The mainhall used the game sound handles as sound instance handles which
probably meant that that specific code never really worked right. I
removed the code since there was no better alternative for fixing it.
This introduces a new mechanism for handling bit flags. Instead of using an int (or two, or three) to write bits into, this uses the std::bitset in a wrapper class that accepts an enum class as input. This means that certain classes of errors we've had a few of in the engine, where a coder used the wrong set of flags or checked them against the wrong variable (SF_STEALTH vs SIF_STEALTH, for example) can now be detected at a compiler level rather than not at all.
Converts Ship_info from a ship_info[] to an SCP_vector<ship_info>. ship_info now has proper constructors, assignment operators, and a destructor. Num_ship_classes removed; various references to Num_ship_classes and/or MAX_SHIP_CLASSES (which remains for various other structures which need it) changed to Ship_info.size() instead.
This doesn't make the ship class limit dynamic, but it is a preparatory step to get there.
