Adds missing fallback behavior that appeared in at least LSL6-Hires.
Removes a workaround that only addressed a symptom of this bug;
the buggy scripts only execute when a correct call to kResCheck fails.
- Clicking four times on lobby sign no longer crashes
- Sound effect now plays when quitting during end credits
Fixes bug #13549
We have several SCI32 script patches that replace kGetTime spin loops
with calls to kWait for the intended delay. This prevents blocking
the main thread and allows ScummVM to be responsive and update the
screen. But kWait isn't a simple sleep, it's a throttling function,
and the duration that it sleeps (if any) is determined by the time
since it was last called. kWait was only in SCI16 interpreters so it
had to be restored to SCI32 and this required a further workaround
for Phant2 compatibility.
Now we have a dedicated custom kernel function, kScummVMSleep, which
does a simple sleep so that SCI32 script patch delays are consistent
and the Phant2 workaround isn't needed. This approach is similar to
kScummVMSaveLoad.
kBitmap's kernel signature is incorrect and out of sync with the
signatures of its sub operations, causing valid calls to subop #1
(BitmapDestroy) to fail. BitmapDestroy allows an invalid reference
to be passed, which GK1 Mac does when decoding the Rada drums in
room 410, but kBitmap's signature doesn't.
Fixed by applying the correct signature, which is the same as kFileIO
which has a similar structure: require an integer for the subop and
then allow anything, including invalid references.
Implements kInputText, which displays a black and white utility dialog
with a title and a text box in a fixed position using the system font.
The only known game that uses this is Phantasmagoria 2 for several
easter eggs, which now work. This was probably used by internal scripts
during game development.
kEditText and kInputText share a function in Sierra's interpreter for
processing events, so that code has been factored out and placed in
GfxControls32::processEditEvent().
GfxText32 can now measure text pixel height as SSCI did by identifying
the tallest character height in the current text, which the newly added
titled font bitmap code requires.
Fixes bug #10570
Allows patching a Phantasmagoria 1 script to copy instead of rename.
Although most games can call this through their File:copy script, none
have been discovered yet that do.
Prevents Phantasmagoria 1 from crashing while in censored mode.
The "blob" subops pixelate rectangles during playback and are
currently being implemented.
Also gate them behind the presence of a 184.VOC resource instead of GID_CATDATE. This should not matter with regards to the remap effects -- the 2015 and 2016 demos had none, and the first that did has an unknown release status. Only the 2017 demo would fall, which would be easily fixed by dropping in a valid 184.VOC patch file.
Restarting was only supported in QfG4, GK1 and PQ4. Those three used
makeshift script code. The kernel call was stubbed out in SSCI as
well. Fixes bug #10681.
This subop is used only by RAMA.
The VMD objects in RAMA's game code contain a frame rate field,
which is usually -1, but occasionally is not. In the cases where
it is not -1, it appears to be either set for a video with sound
(so the value doesn't do anything to that video), or it is just
resetting back to the baked-in frame rate of the video file (so
it doesn't need to exist, except to fix videos broken by earlier
played videos with explicit frame rates).
Since this is a global state flag that does not get reset in SSCI,
the ultimate effect of kPlayVMDSetFrameRate in RAMA is that it does
nothing to any of the videos where the explicit frame rate is set,
but it does inadvertently cause *other* videos with no sound and no
explicit frame rate to have a different frame rate depending upon
what was played earlier in the game (and whether or not the engine
was restarted in the meantime).
This bad transferring of frame rates is most noticeable with the
exit-video of the vidmail player, which is played when you back out
after selecting a vidmail. Its nominal framerate is 10fps, but it
will play at whatever frame rate was last set by some other video
that happened to have an explicit frame rate, even if that frame
rate was bogus.
So, just ignore all calls to this subop, as it is fatally buggy.
Near the end of the game, RAMA will start trying to store some
invalid references. This does not affect the save game negatively
in any way, but it was causing the kernel to assert a signature
failure.
In the original interpreter, is it valid to pass a null reference
to both kArray(GetData) (it just acts as an identity function when
the passed argument is not an object) and to kString functions (it
always dereferences to an empty string).
Fixes Trac#10039.
Non-use of these kernel calls was assumed by reviewing script
disassembly by SV, but it turns out that SV was not picking up
script patches correctly in SCI3 games, so this data is no longer
considered reliable.
Upon investigation of Sound code across SCI32 games, it was
determined that there are actually (at least) 3 different
revisions, not just a single SCI2.1 version. This patch only
changes the parts of Sound code that are relevant to the correct
use of Audio32.
Fixes Trac#9736, Trac#9756, Trac#9767, Trac#9791.
This "fix" is more of a hack, in the interest of making the game
completable. The root cause is a combination of two problems in
the game scripts:
1. Blink::init expects to receive either 0 or 2 arguments, but
it assumes that if it received *any* arguments, it must have
received 2 arguments. This assumption is wrong, though,
because--
2. soTorinWhoAreYou::changeState(0) calls
poPecandEyes::setCycle(Blink) without including a second
argument (the blink speed).
This ends up with the second parameter being some garbage, and
that garbage gets sent to kRandom which then complains about
receiving garbage.
The correct fix for this would be to fix soTorinWhoAreYou (in
script 51400) to pass a second argument to setCycle, but there are
not enough obvious spare bytes for a quick and easy patch, so this
workaround will have to do for now.
Fixes Trac#9779.
