#8775 closed patch

Basic savestate plugin API

Cc: Game:


The attached patch implements a basic savestate plugin API. It is not yet quite ready for SVN, but I thought people might already want to have a peek at it or comment, so I am putting this into a tracker item for now.

Basically, it adds a new plugin API function, which can be used to query a plugin for a list of savestates for a given target. Currently, in the patch this is only implemented for a single engine (the SCUMM engine). My hope is that for other engines, the resp. engine maintainers will help out.

Eventually, this would make it possible to add a feature to the launcher where the user can directly load a specific savegame instead of first loading up a game, then navigating to its save/load system. However, this is not yet implemented, and one would have think about a good GUI for this, too. (For example, add a "load savestate" button which pops up a dialog with a list of all saves, and lets the user choose one. Or change the launcher to display a tree display, where all saveslots for a given target are displayed as children of that target in the main launcher list).

Right now, the only way the new API is used is via a hack to the --list-targets / -t command, which was extended to also list all savestates for each targets. This might eventually be turned into a separate --list-saves command, of course. It is only there to show how to use the API, and to demonstrate that it actually works.

Updated version of the patch, which also stores the filename in the SaveStateDescriptor. This makes it possible to e.g. delete a specific savegame/savestate from within the launcher.

BTW, we should probably fix the terminology at some point: savegame vs. savestate vs. savefile...

Maybe it would be better to put static SaveStateList Engine_XXX_listSaves(const char *target) to ADVANCED_DETECTOR_DEFINE_PLUGIN macro?

Otherwise the patch looks like an excellent start

comment:3 by fingolfin, 16 years ago

I don't see how that would be useful -- the advanced detector has nothing to do with the listSaves() functionality. They are completely independant of each other...

So I just commited an updated version to SVN, featuring a new "--list-saves" command line option (not yet documented).
