The autosave refactoring that was done in
7adad5aaf5 used g_engine for identifying the
autosave slot. This worked for in-game save/load, but doesn't fit when
called from the launcher.
Fix by passing MetaEngine to SaveStateDescriptor ctor and using it for this
query.
Amends 7adad5aaf5.
Some engines call setAutosave and some don't. isAutosave is used to
determine if a saved game is an autosave, but in fact, on most cases it
just falls back to comparing the name to "Autosave".
This is wrong for several reasons:
* Older versions of ScummVM used Autosave 0.
* The name "Autosave" is translated, so if you change the language, it
won't be detected.
Instead of relying on the name, use the well-known getAutosaveSlot() from
Engine/MetaEngine.
Fixes#12735.
This employs a "lazy" approach: the "format" for the credits stays
exactly as it was, i.e., perl code. Of course one may want to change
this to another format (e.g. YAML, JSON, XML; or also shell script or
AWK, like `configure.engine` uses). But I deliberately kept it simple,
to get a minimal change that is easy to verify. Any further changes to
e.g. the format can be layered atop this.
For each engine:
- Make a new folder detection
- Move detection-related files inside the folder
- Add a new module "enginename/detection"
- Add DETECT_OBJS here
- Adjust the normal engine module to remove detect_objs
- Adjust every file for the new changes.
Up until last commit, everything was working fine but the amount of files changed was too large. This commit tries to reduce the changes.
- Add a fake constructor to Keymap, text-to-speech, setDescription (save-state)
- Redirecting functions for PopUpWidget::appendEntry, ButtonWidget::setLabel, GUIErrorMessage
- Use the above functions and constructors to reduce changes in Engines
- Fix warnings being in unicode. Only output english text in - Warnings, Errors, etc.
- Mark some strings as "translation" strings. (Not yet added to POTFILES)
- Remove some CP related things from po/modules.mk
- Previously used some Common::convertToU32 where it was not necessary, replace this with u32constructor
- 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.
After the initial changes just to scummvm/gui for u32, this commit includes the whole project
- Widget creations now always have u32 descriptions, labels, or tooltips
- Message dialogs make use of default arguments instead of providing the same argument explicitly
- encode String::format properly before passing on as argument where necessary
- Modify hugo utils (yesNoBox and notify box) to use u32
- Also provide fake constructors for the above which redirect to the u32 constructor
- Convert all keymap descriptions to u32 across all engines
- showConfirmationDialog in mohawk now uses u32
- showScummVMDialog also uses u32
- Scumm engine has dialogs now which use u32
- General fixes and wrapping convertToU32String for setLabels and related functions
- Add a fake constructor to MesssageDialog which redirects to the u32 constructor
This removes filename methods when it matched the Engine method.
Secondly, ensuring there was an overriden getSaveStateName method
for engines that didn't do the standard target.00x save filenames
This commit introduces the following changes:
1. Graphics::loadThumbnail()
Now returns a boolean and takes a new argument skipThumbnail which
defaults to false. In case of true, loadThumbnail() reads past the
thumbnail data in the input stream instead of actually loading the
thumbnail. This simplifies savegame handling where, up until now,
many engines always read the whole savegame metadata (including
the thumbnail) and then threw away the thumbnail when not needed
(which is in almost all cases, the most common exception being
MetaEngine::querySaveMetaInfos() which is responsible for loading
savegame metadata for displaying it in the GUI launcher.
2. readSavegameHeader()
Engines which already implement such a method (name varies) now take
a new argument skipThumbnail (default: true) which is passed
through to loadThumbnail(). This means that the default case for
readSavegameHeader() is now _not_ loading the thumbnail from a
savegame and just reading past it. In those cases, e.g.
querySaveMetaInfos(), where we actually are interested in loading
the thumbnail readSavegameHeader() needs to explicitely be called
with skipThumbnail == false.
Engines whose readSavegameHeader() (name varies) already takes an
argument loadThumbnail have been adapted to have a similar
prototype and semantics.
I.e. readSaveHeader(in, loadThumbnail, header) now is
readSaveHeader(in, header, skipThumbnail).
3. Error handling
Engines which previously did not check the return value of
readSavegameHeader() (name varies) now do so ensuring that possibly
broken savegames (be it a broken thumbnail or something else) don't
make it into the GUI launcher list in the first place.
Initializing Common::RandomSource's seed with a fixed value will always
yield the same sequence of pseudo-random numbers which is probably not
desirable. Since the constructor takes care of initializing the seed
properly doing so manually is not needed.
This flag is removed for a few reasons:
* Engines universally set this flag to true for widths > 320,
which made it redundant everywhere;
* This flag functioned primarily as a "force 1x scaler" flag,
since its behaviour was almost completely undocumented and users
would need to figure out that they'd need an explicit non-default
scaler set to get a scaler to operate at widths > 320;
* (Most importantly) engines should not be in the business of
deciding how the backend may choose to render its virtual screen.
The choice of rendering behaviour belongs to the user, and the
backend, in that order.
A nearby future commit restores the default1x scaler behaviour in
the SDL backend code for the moment, but in the future it is my
hope that there will be a better configuration UI to allow users
to specify how they want scaling to work for high resolutions.
Recently we started to use this as new semantics, although in the past
we used simly <engine>_H. Now these guard defines are consistent with
rest of the files which are used in the engines.
