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.
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.
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.
This code is currently untestable and is almost certainly at least
partly based on guesswork & not actual reverse-engineering (as was
the case for all other pre-2015 SCI32 code), so future developers
interested in adding SCI32 Mac support should use it only as an
intermediate reference rather than as known good code.
This changes the syntax for bpk and logkernel:
Enable breakpoint on kernel call:
bpk FrameOut
Enable logging for kernel call:
bpk FrameOut log
For backward compatibility this has an alias: logkernel FrameOut
Removing a kernel call breakpoint is done with bp_del/bc now.
This change invalidates earlier SCI32 save games, which separated
arrays and strings in an incompatible manner. Old save games
contain invalid references to a string segment which no longer
exists, and contain incompatible array structures that lack
critical type information.
These were introduced in SCI3, and are used by RAMA. We don't preload
videos, so we don't really need kPlayVMDSetPreload, but
kPaletteSetGamma may need an implementation.
With these two stubs, the main menu of RAMA is working again
