When the code checks for the existence of an audio file, be sure to check all relevant extensions.
This fixes#4495. Tested with both ST:R personas as well as the Vasudan persona.
A few assorted fixes for timestamps:
1) The pre-player delay should be fast-forwarded by 1/4 second per frame regardless of time compression
2) If time compression is very slow, there could be a 0-millisecond change in timestamps, so don't adjust this
3) Properly handle a change in soundtrack that occurs during a mission, not just when the mission is parsed
The timestamp fix/cleanup in #3878 revealed a longstanding bug with music timestamps--the timestamps were never set to something valid later.
This is a widespread issue in the code, fortunately Goober is modifying the timestamp code to accommodate invalid timestamps.
Tested and works as expected. Fixes#3930.
a) add a new method gamesnd_game_sound_exists
b) add script support for this new method
c) use this method when checking for existence of ballistic rearming sounds
d) prevent "empty" and "none" sounds from triggering warnings
This system adds the code necessary for letting content creators specify
complex events by specifying a simple, program-like sequence of
operations that will be executed by the engine when a certain event is
triggered.
One small detail that was overlooked in PR #3021... KeldorKatarn's old code used `strtod` while the new code used `stuff_float`. This wouldn't be a problem except that a couple MVP models use annoyingly formatted floats like 8.9e-08. So I decided to convert `stuff_float` to use `strtof` and do some more upgrades while I was at it.
This PR refactors the function's name to something more indicative of what it actually does, and removes a call made to it from within freespace.cpp which, due to changes in how the soundtrack system works, is now redundant and doesn't actually do anything anymore.
The largest new feature is that it is now possible to include other
files into the RML by using the "include" tag. This is useful for making
markup files more modular.
Also added some more options for existing things (e.g. built-in detail
options).
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 converts the previous int handles to a strongly-typed wrapper
handle which will make the API more self-documenting and will ensure
that wrongly used handles are detected at compile time.
I already found a few mistakes with these changes which I also fixed
here.
If a sound did not receive a valid sound name then the parsing function
would exit early and not set the pitch range properly. This would cause
a divide by zero if the duration of the sound was queried.
This moves the initialization of the pitch range to the start of the
parsing functions which makes sure that the range is initialized even if
the function exits early.
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 can happen if a script tries to determine the length of a sound
before actually playing it. This fixes the assertion by loading the
sound when it is necessary.
For some reason, commit 8b43ed823c moved the consumption of the "#Soundtrack End" token out of parse_soundtrack(), when if a soundtrack needs to be skipped (e.g. because it's in a .tbm, flagged with +nocreate, and the original doesn't exist), it will skip straight past "#Soundtrack End" to reach the next "#Soundtrack Start". It also changed how music tables are parsed so that they'll skip any junk data that happens to be between sections, which is atypical of how tables are parsed. This commit changes both of these things: "Soundtrack End" is once again consumed near the end of parse_soundtrack(), and the while loop uses check_for_string() instead of skipping to the start of a section.
This adds support for specifying multiple sounds for a single game sound
entry. The engine then selects which sound will be played based on the
strategy provided by the game data. This required a few changes to some
of the game code since previously every game sound had exactly one sound
file attached to it. The most notable change is that it is no longer
possible to determine the exact duration a sound can have so instead the
new code computes the maximum duration a sound can have and uses that
where appropriate.
This also adds support for randomizing the pitch and volume of the sound
to provide a more varied experience even if only a single sound is used.
One possible issue that exists is that the "sequential" strategy only
works globally at the moment so if two sources use the same game sound
concurrently then the two sources will share the sequence of sounds
since there is no sound instance data at the moment. That can be added
in a future change but should not present a huge issue for most
use-cases.
Visual Studio on Appveyor somehow causes deprecation error on _our_
definition of vsprintf. I have no idea why these changes introduced this
warning but I won't debug Visual Studio compiler bugs that I can't
reproduce with my Visual Studio version so I just disabled those
warnings.
This makes it easier to determine what takes the most time while loading
the mission (loading models) and how we could optimize that load time
(optimize model loading).
This is not a bug fix but it also shouldn't cause any regressions since
there are no actual code changes so this could be merged before the
release of 3.8.
The codebase had quite a few instances of .size() being called and then checked to see if it was 0 or not (or less than 1, or greater-than-or-equal-to 1, which are basically equivalent), when .empty() could be called instead (negated or not, depending on what the original condition was).
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.
