With the addition of autosaving support, deleting saves
(via the gui) to slot 0 was disabled, but for saves that
have been previousl created by the user it make sense
that they should be allowed to delete a save in slot 0.
Fixes Trac#10536.
The previous logic was enabling autosaving if the metadata
file was not present, but saves from the original
don't have metadata. Now it checks if the non-metadata
file can be loaded to determine if the slot is empty.
The game will autosave to slot 0 using the save
period given in the scummvm config file
or when the user exits using the GMM.
Autosaves are only allowed when an autosave is
in slot 0 or there is no save in slot 0.
This will not override any saves the player
has previously put in save slot 0. If there
is a save in slot 0 that is not an autosave
then there will be no autosaving.
The global variable "ending" tracks various
states that Atrus can be in.
This variable determines what video of
Atrus will be playing and if the brother
books have been destroyed.
Despite this variable being called ending
there are other endings not captured by
this variable (like the brother endings).
Also change spelling of Dini to Dni for one
usage of ActiveAge from a previous commit.
This global basically tracks what age/book/stack
the player is in.
It is also used to change stacks via
MohawkEngine_Myst::changeToStack() by
being an index for MystScriptParser::_stackMap
and MystScriptParser::_startCard.
E.x., instead of _global.currentAge = 2
now _global.currentAge = kMystLibrary.
Also two of the endings are considered Ages
instead of being apart of _global.ending.
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.
Myst previously used the user provided description as the save filename.
This was not working when the user entered chacacters forbidden by the
filesystem.
The actual save format has not changed. Old saves are still compatible,
but must be renamed to 'myst-###.mys' and 'myst-###.mym'.
Fixes 7106.
This fixes a bug where the player could be stuck on Channelwood's
lower level with the elevator on the upper level.
This also turns the light off on Stoneship when entering the age,
since the battery is depleted.
Thanks to dtungsten for submitting this fix in PR#478.
