Remove One Source of Client and Server having Different Timing
Multiplayer *must not* have its time affected by being in the background, because their clocks will come out of sync and movement from an out of focus multiplayer instance will appear to move in slow motion. This fixes the timing discrepancy by only doing os_sleep when unfocused when in single player.
For compatibility purposes some mods want alt names to truncate at the hash symbol. But we can't actually do that at mission load,
since we have to save them again in FRED. So this commit processes the names just before the mission starts.
To further complicate things, some mods actually want the hash to be displayed. So this commit introduces the double-hash as an escape sequence for a single hash.
This is necessary for multi to ensure that music is stopped.
common_select_close() would do this, but it's never inited for
these screens. So we need to manually do it if we aren't
transitioning to a screen with common_music.
* Object Update Refactor
1. Keeps the object update packet aligned, even if the ship is dying or has not yet arrived on the client.
2. Properly handles model point shields (yes, that's what was causing multi to crash the most!)
3. Reworks positional interpolation timing and adds rotational interpolation, by sending timing information with every object update packet in a header shared between objects.
4. Saves a lot of bandwidth by only sending data that is changing. (no more sending all subsystems once per second!)
5. Better handles out of order packets (but can still use their information if recent enough!)
6. Builds the basis for Rollback by beginning to record the positions and orientations and velocities of ships for the last 30 frames.
7. Adds subsystem rotation -- Yeah, you saw that right, subsystems will now spin in multi.
8. Waypoint movement is now enabled via sexp, and time to arrival of waypoints is updated on the target info gauge.
* Fix edge case crash and Incorporate feedback
* Clean Up Interpolate Angles Quick
* Restrain the client
* How was this still here???
* Make sure every part of OO uses OOC_INDEX_NULLPTR_SUBSYSTEM define
* Fix Way to Store Return Values
* Ok travis, we get it
* Ok travis.........
This is a follow-up to #2100. Don't pause/unpause the audio if we are moving from/to the Control Config or HUD Config screens. We could hit F2 and move around a bit before resuming the game, so we don't want the audio to resume until we're ready.
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.
Several things going on here:
1) refactor `get_display_string()` to `get_display_name()` to be more precise
2) likewise, refactor `alt_name` to `display_name`
3) automatically generate display names when parsing the ship, ship class, and weapon class for the first time
4) remove the on-the-fly truncation of names with hash symbols
Basically this subsumes the `end_string_at_first_hash_symbol` logic into the display name. Rather than truncate the name every time it's displayed, truncate it once when it's parsed. This takes advantage of the previous display name infrastructure, since display names are a superset of the case of truncating the hash symbol.
This also has the benefit of now allowing hash symbols within display names. When updating Destiny of Peace, I noticed that "Lockheed Shuttle #4" would no longer display properly; and it was not previously possible to fix this even with display names.
I could pull out the `get_display_string()` and `alt_name` renaming into a separate PR if desired.
This can be used for producing even leaner builds for standalone
servers. It also provides a nice architecture verification since now
using internal OpenGL functions will cause a compilation or linking
failure.
This adds an Antlr grammar for parsing argument lists instead of using a
hand written parser. This allows to write much more complicated syntax
constructs and have all the code being auto-generated. It will also
produce a much more correct parser instead of having all those hacks in
the hand-written one.
This also adds (in addition to supporting the previous syntax) support
for function types along with support for them in HTML and JSON output
formats.
The ANTLR generated parser is included in source form so that it is not
necessary to have an ANTLR installation around if you are not going to
change the grammar. Also includes the necessary runtime code from Antlr.
If a standalone has only one player connected in a dogfight mission it will crash. Not fully sure why this doesn't crash in other circumstances, but this check should just be here, anyway.
This adds a mechanism for running generic operations at specific points
of the frame execution. This can be used by any part of the code an not
just Lua since it simply executes std::functions. It also adds an
"execution context" concept that specifies in which situation an
operation should be executed.
This is then used by the Lua Coroutines code for resuming coroutines at
specific points instead of always when the awaited promise resolves.
This adds the capability to have a Lua script that does not need to use
our table syntax at all but instead defines the hooks by calling API
functions. This also makes it possible to add hook functions at runtime
if the script requires that.
Also clean up some unused debug stuff.
This updates #2299 and restores the use of `event_music_level_start(-1)` in `freespace.cpp`. This call was removed in #2299 because it was thought to be redundant but removal of that call resulted in music not playing upon mission restarts. This PR restores that call and fixes that issue.
This moves towards defining the hooks in the code module that executes
them. Also provides the API necessary for better documentation of hooks.
This only covers a few hooks as a test and demonstration of the new API.
If no issues are found with this it can be extended in the future.
