1. If the sample queue is too long, frames will be skipped. This
prevents bursting with a bunch of voice packets at once.
2. The Opus frame size is doubled to 20ms to reduce UDP overhead.
3. The Opus bitrate is reduced from its default to 10kbps, to prevent
potential UDP MTU size overruns.
4. The server will ignore Opus frames past a certain limit per tic from
each player, preventing excessive voice packet propagation
5. Push to talk no longer eats chat typing, and no longer responds while
chat mode is on.
This avoids an issue where the skins array takes up a fixed, but large
amount of memory at runtime. On x86_64 linux, that array is roughly 80
megabytes in memory, most of which is unused when the game is unmodded.
Instead, we treat `skins` as a dynamically resizing array, and it is an
array-of-pointers into separate allocated `skin_t`.
This is based on Lactozilla's skin limit MR for SRB2, but I've rewritten
it because RR has diverged quite a bit.
This was verified to check every access of `skins` by using clangd's
find-all-references function. However, I have only tested plain skins,
not Lua addons, so that could afford some extra checking.
Implemented using libopus for the Opus codec, same as is used in Discord.
This adds the following cvars:
- `voice_chat` On/Off, triggers self-deafen state on server via weaponprefs
- `voice_mode` Activity/PTT
- `voice_selfmute` On/Off, triggers self-mute state on server via weaponprefs
- `voice_inputamp` -30 to 30, scales input by value in decibels
- `voice_activationthreshold` -30 to 0, if any peak in a frame is higher, activates voice
- `voice_loopback` On/Off, plays back local transcoded voice
- `voice_proximity` On/Off, enables proximity effects for server
- `voice_distanceattenuation_distance` distance in fracunits to scale voice volume over
- `voice_distanceattenuation_factor` distance in logarithmic factor to scale voice volume by distance to. e.g. 0.5 for "half as loud" at or above max distance
- `voice_stereopanning_factor` at 1.0, player voices are panned to left or right speaker, scaling to no effect at 0.0
- `voice_concurrentattenuation_factor` the logarithmic factor to attenuate player voices with concurrent speakers
- `voice_concurrentattenuation_min` the minimum concurrent speakers before global concurrent speaker attenuation
- `voice_concurrentattenuation_max` the maximum concurrent speakers for full global concurrent speaker attenuation
- `voice_servermute` whether voice chat is enabled on this server. visible from MS via bitflag
- `voicevolume` local volume of all voice playback
A Voice Options menu is added with a subset of these options, and Server Options has server mute.
Allows the user to configure the mixing buffer size to reduce
latency at the cost of higher CPU usage, or vice versa.
This also raises the default buffer size from 1024 to 2048, to
address some underrun problems people have with the current buffer
size.
- `EncoreMusic` on mapheader
- Supports up to 3 alt musics, as with every other type
- Do not vape/nightcoreify if provided
- To avoid complicating the Alt Music logic too much, uses "side B" of the same Prison Egg CD
- That is to say, if there are 2 encore tracks and 3 normal tracks, the second Encore track will only play if you've gotten the CD associated with the second normal track
I haven't actually tested it *with* any Encore music, but I've triplechecked literally everywhere to make sure it didn't break standard play
- cursongcredit behaves the same as before
- Always compose song credit string
- g_realsongcredit always stores the song credit for the
current music, even if no song credit is displayed on
the HUD
Master volume should control after-mixing gain; the idea is the mixed
output of sfx and music's amplitude should never exceed
`cv_mastervolume`. Setting each submixer's gain independently will
still allow the master mixer to exceed that preferred volume, which was
the main issue with the SDL_Mixer backend. So, instead we use a separate
gain control that is applied after everything is mixed.
- The order that cvars appear in the config is messy, so
music appears before musicvolume
- When musicvolume is changed, music is forced to On,
which would ignore the config value
All courses are restricted in Match Race/Time Attack/Online if not visited in GP UNLESS:
- It is the first Race Course of a Cup
- Course has "NoVisitNeeded = True`
- The Controls Tutorial and Test Run are the only two stages that will need this
The above replaces:
- A lot of restricted courses having to be marked with `FinishNeeded = True`
- Hidden Palace
- Sealed Stars 1-14
- Once Special Mode is unlocked, it will now be possible to practice Sealed Stars before rematching them in GP
- Almost all Tutorial-specific behaviour, since it was heinously hacky
HOWEVER, `FinishNeeded = True` was left in specifically for future releases, and I reserve the right to use it on Adventure Example again before launch.
- Starts both stereo and stereo_fade in tandem
- Suspends the tune which is not to be heard
- Swaps suspension when toggling SEQ
- Special handling so fade-out can not be interrupted by
switching off SEQ
- Updates music and sound volumes simultaneously
- Changing music/sound volumes separately sets master
volume to highest of the two
- Visually distinct slider
If player is in one of these states:
- Invincibility
- Grow (K_IsBigger)
- Flame Shield dash
- Over 200% speed
And the other object:
- Does not have MF_DONTPUNT
Then, touching a solid object:
- Punts the object, unless the object has MF_ELEMENTAL
- Fizzles the object, if the object has MF_ELEMENTAL
Or, when an object damages the player:
- That object is punted, unless it has MF_ELEMENTAL
- The object fizzles, if it has MF_ELEMENTAL
Punting means:
- A copy of the object is made
- Both the player and copy receive 5 tics of hitlag
- The copy is thrust away from the player at a minimum of
60 FU, or 2x either the player's or object's momentum,
whichever is ultimately greater
- The copy despawns after 2 seconds
- The copy flickers constantly, while thrust away
Fizzling means:
- The object disappears completely
- A puff of smoke is spawned in place of the object
- No hitlag is applied to the player
Both punting and fizzling:
- Hide the original object (intangible and invisible)
- The original object reppears after 30 seconds
- For 2 seconds before reappearing, the object flickers
back in, but is still intangible
