How could I open a save file with my unreal game?

Development Programming & Scripting

I want to make it so savegame files can be double clicked in order to open them with the unreal game-application.
Just like how a .txt files open with notepad, id like my savegame files to open with my unreal game.
Can anyone give me advice on how to go about that?

Can’t be done, I would say ( unless you want to edit the engine ).

I’d lay money on it.

How’s it supposed to work? How does know which map to load etc?

I imagined the path to the file your opening would be passed to the unreal game. You would use this path to read the save file. A save file can contain any information really, including the map name.

I don’t see why it can’t be done. You can use custom command line args to read and parse from within your code. You would create your own key-values and then process them, otherwise the engine won’t recognize them and they will be ignored.

Yes, technically it might be possible. But it’s not an ‘out of the box’ thing.

You’d also need to tell the operating system to run your game when a save game was double clicked.

Yeah you’d have to decide upon a custom file extension for your savegames (preferrably unique), then create a custom installer to set up windows registry to associate file extension with your game’s executable. All of this is not really UE realm.

Once properly setup, the operating system will run your exe with the double-clicked file as argument, which you can retrieve via FCommandLine functions.

Thanks that works. I used FCommandLine::Get()
