This commit addresses a range of changes, within scummvm subproject.
- Audio files, like mididrv, remove U32String based name and identifier, because ASCII only.
- mididrv.cpp had some wrong format for warning messages, fix those
- Message dialogs were modified to use default arguments more often, but reverting back to the orignal to minimize changes.
- SetTooltip has a fake constructor that takes in a string, and use it.
- U32Format had some break statements missing, add those.
- RemapWidget: Use fake constructor for setLabel and setTooltip, to make minimal changes
- SDL: setting text in clipboard no longer uses SDL_iconv_string
- TTS: Override base class "say" with strings, so tts->say can be used with normal strings too.
- About dialog: fix incorrect code for u32string variables
- Fix some extra brackets
- Some buttons were incorrectly removed from using translated labels, revert those
- Message Dialog: Pass default and alt buttons as const references
- Saveload Dialog: Use translations in missing places, use const-references. Also, use translations in a correct manner.
- Use const references for tooltip in GraphicsWidget, EditTextWidget, error.cpp
- DomainEditTextWidget: Use U32String for text
- Use the fake constructor for message dialog less often
- solve errors regarding comparision between string and u32string in midi
- solve errors in testbed/speech related to ttsMan->say
- fix unsigned comparision warning in tab.cpp
- fix issue with static strings and translations in sdl-graphics
- Where necessary as in, where translated messages are used.
- GUIErrorMessage now takes in U32String
- error messages across some engines use U32Strings. they are changed because they show a message dialog.
This commit also includes some additional major changes.
- Return U32String from TransMan getTranslation()
- Change tooltips to be U32Strings
- Remove temporary code of convertToU32String
- U32 Support various dialogs (Browser, FileBrowser, Messages, Chooser, etc)
- U32 for music plugins
- U32 for OSD messages
- Add some helper functions to ustr.cpp
- Change default tooltips from nullptr & 0 -> ""
- Some runtime exceptions may occur when changing languages due to incorrect String::Format
When the MIDI parser wanted to stop all notes on a MIDI device, it would send
an All Notes Off message and, optionally, a Sustain off message on all 16 MIDI
channels. This is inefficient for devices like the MT-32, which uses only 9
channels. The MT-32 hardware is also quite slow, so it is more responsive if it
has to process less messages.
I've added a generic stopAllNotes message to the MIDI driver using the old
method, which can be overriden by more specific implementations in subclasses.
The Miles MIDI driver implementation sends All Notes Off only on the channels
used by the MT-32. There are probably also more efficient implementations
possible for f.e. AdLib.
* KYRA: Added GM initialization for Lands of Lore
The original interpreter of Lands of Lore uses two executables, which
both do initialization of MIDI devices. The main executable runs a
sysex file for GM devices; the intro executable does not.
ScummVM only does MIDI initialization once and it performs this like
the intro executable. I've added the GM initialization of the main
executable. Note that the initialization file consists mostly of
sysexes which alter the display of the SC-55, so it's not particulary
useful. Not many games did this though, so I thought it would be a
fun feature to include.
I also noticed that the check which distinguishes between the two
demo versions of LoL did not work properly; the useAltShapeHeader
flag was true for both versions. I've changed it to check for the
existence of a PAK file which was only included with one of the two
demos.
* MIDI: Delay parser after handling SysEx events
This changes the way delays between SysEx events in MIDI data are handled from
delaying the backend to delaying the MidiParser.
SysEx events require a delay between events to ensure correct processing by the
MIDI device. This is usually implemented by calling OSystem::delayMillis.
Some games use some form of MIDI sequence filled with SysEx messages to
initialize the MIDI device. This is handled by the MidiParser. Using the
delayMillis method causes the following MIDI events to be "bunched up" and be
executed in a shorter timespan than intended.
I've altered this by making the MidiParser stop parsing when a SysEx event is
encountered and not enough time has passed since the last SysEx. After enough
time has passed, the next SysEx is sent and parsing resumes. To facilitate
this, I've introduced an alternate sysExNoDelay fuction on the MidiDiver. This
does not execute the delay itself, but instead returns the required delay time,
so the parser can handle this instead.
I've currently only implemented this method for the Miles MT-32/GM driver. For
other driver implementations, this will call the regular sysEx method and
return a 0 delay time, so there will be no change in behavior.
This restores a sound effect at the end of the Legend of Kyrandia MT-32 MIDI
initialization. Before, the Note On and Note Off events would be transmitted
instantly after each other, causing the notes not to play.
* MIDI: Add instrument bank fallback
Some games rely on a feature of the Roland SC-55 v1.xx that corrects invalid
instrument banks. This feature was removed in later versions of the device and
not implemented in most other GM devices, causing some MIDI data (sound effects
mostly) to play incorrectly.
Specifically, this applies to Lands of Lore. For example, in the intro, the
sound effect of the ring sparkling uses an incorrect instrument bank. Depending
on how the MIDI device handles this, the sound will play correctly, with the
wrong instrument, or not at all.
This commit emulates the SC-55 functionality that corrects the invalid bank
numbers. I've implemented this (partially) on the MidiDriver, so that it can be
re-used for other games (Xeen 4 and 5 also have this issue with some sound
effects).
* KYRA: Start MIDI playback after selecting track
The MIDI parser would automatically start playback after loading MIDI data, but
KYRA engine games use MIDI files with multiple tracks. Because of this it was
necessary to immediately stop playback after loading MIDI data, and then select
the track that should be played for correct playback. The parser now has a
feature to disable automatically starting playback, so I've implemented this
for KYRA.
* KYRA: Improve stopping MIDI playback
In two places All Notes Off events were sent on all channels to stop MIDI
playback of the background music. However, this will also cut off any MIDI
sound effects which are playing. Where needed I've replaced this with simply
stopping playback of the background music; the parser will turn off any active
notes.
I've also made sure playback is stopped before freeing the music data
memory to prevent any issues.
I've added sending All Notes Off events when the game quits, just in case any
hanging notes are not ended by the parsers (should not really be a problem
though).
* MIDI/KYRA: Add pausing playback to MIDI parser
* KYRA: Fix invalid track selection
If a game would attempt to play an invalid track, the parser would start
playing the previously selected track. Fixed this so the parser will not start
playing.
* MIDI/KYRA: Add channel locking and GM to XMIDI
This improves support for XMIDI channel locking and moves it from the KYRA
engine to the generic Miles MIDI driver. To support this, a source parameter
is added to the XMIDI parser and Miles driver so the driver can distinguish
several XMIDI parser instances sending MIDI events. I've also added GM support
to the generic Miles MIDI driver.
The previous implementation of channel locking did not always track and restore
controller values properly when unlocking a channel. Specifically, at the start
of Legend of Kyrandia, when Brandon talks to the tree, the tree "creaking"
sound effect uses some channels from the background music. The volume of the
music channels was not correctly restored, resulting in some instruments being
much louder then others.
Another issue was that volume was not always properly set when locking a
channel. In the Legend of Kyrandia intro, when Brandon is lifted up to the
house, some sound effects were missing because MIDI channel volume was 0.
This new implementation fixes these issues.
* MIDI: Suppress Miles controller warnings
Several Miles controller MIDI messages generate warnings in the XMIDI parser,
even though they are handled by the Miles drivers. I've removed these.
* MIDI: Fix Codacy issues
Previously, a C-style cast was used to convert a
Common::Array<Plugin *>, populated with pointers to StaticPlugin
and DynamicPlugin instances, to a
Common::Array<PluginSubclass<T> *>, but PluginSubclass<T> is a
*sibling* class to StaticPlugin/DynamicPlugin, so this cast was
invalid and the results undefined. The methods for retrieving
subclasses of plugins can't be easily changed to just generate an
array of temporary wrapper objects that expose an identical API
which dereferences to the preferred PluginObject subclass because
pointers to these objects are retained by other parts of ScummVM,
so the wrappers would needed to be persisted or they would need to
just re-expose the underlying Plugin object again. This indicated
that a way to solve this problem is to have the callers receive
Plugin objects and get the PluginObject from the Plugin by
explicitly stating their desired type, in a similar manner to
std::get(std::variant), so that the pattern used by this patch to
solve the problem.
Closes gh-1051.
When clearing an existant object clear() should be used.
When constructing objects (or using default values for parameters) the
constructor of String without any argument should be used.
This changes only a few instances I noticed while looking over some recent
commit logs.
This eliminates nasty limitation of caping number of flags to 31.
Current code has limitation of 255 flags, though.
Only SCUMM engine is converted, rest do not even compile.
Detection of fan talkie MI is broken as it has to be implemented
differently.
This tries to make our code a bit more compliant with our code formatting
conventions. For future use, this is the command I used:
git ls-files "*.cpp" "*.h" | xargs sed -i -e 's/[ \t]*$//'
Silent fallback would occur if the user expressly selected a formerly available audio device which now has become unavailable (switched off, disconnected, no longer compiled in, etc.). A warning dialogue will now be displayed, before the fallback takes place.
This is an attempt to fix the problem Max described in his devel mail.
The presence of the rom files will now be checked in detectDevice().
In case of failure there will be fallback attempts.
The user will get notified of the detection failure if he has expressly selected the device that failed.
Please test with your platform / engine (with or without rom files).
