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.
If the autosave slot doesn't yet have any file in it, when the
GMM save dialog is open, the autosave slot will show a default
'Autosave' entry which is write-only, to prevent users
accidentally making a savegame in that slot
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.
Despite what the comment says this does not seem to be in the original
game and I cannot replicate this in either the original or a current
ScummVM build. It is highly likely that this was one of several sprite
offset bugs which were present in our implementation earlier but which
have since been fixed.
If you don't have the appointment card yet and use the map to go to
Seedy Street Bud ends up being teleported back to the mall.
Because of the destination coordinates which warp Bud past x==583
Violet's logic, which makes him refuse Bud entrance to the dentist,
triggers. On top of that the graphics end up all garbled which
indicates that even worse things happen under the hood.
To work around this we only trigger Violet if Bud actually _walked_
past the trigger coordinates (as opposed to using the map).
This fixes Trac#10452.
When the 'mof' opcode was added in commit 1946dead77 it was implemented
as a NOOP, but what it actually should do is disable the mouse (set
_cursorState to kCursorStateDisabledHidden).
This is used in at least the Spanish and Polish versions of the game to
work around an earlier script bug which allowed the player to use the
mouse while freeing the professor in part two.
This commit fixes the 'mof' instruction so that the original script works
as intended in those versions that ship with the fix.
TODO: Add a workaround for those game versions which don't do the 'mof'
themselves.
This commit adds the 'buv' and 'c0v' opcodes which are used to set speech
volume. Because these only seem to be used once in the English demo and
we right now playback all speech at kMaxSoundVolume anyway we can treat
them as NOOPs.
This fixes a bug in said demo which resulted in Bud being unable to talk
to Del.
