gomenne, i’m not too good in japanese.
into the “Object” pin you have to connect your savegame object, the one you actually save.
you create it with create object, then you save it with async save game, and load it with async load game.
please check the documentation.
it’s pretty much all you need.
i recommend you to have the load and save code grouped together in a class for the future. for example an actor that works as a “manager”.
