Saving & Loading
The save manager is in charge of loading, saving and all the rest of the logic (auto load, auto save, level streaming...). It will be initialized the first time GetSaveManager gets called. Usually at BeginPlay.
When we say slot we refer to the integer that identifies a saved game.
This slot identifies a saved game even during gameplay, meaning that if an slot gets loaded it will be "active" until we load another slot.
With this we can for example do "SaveCurrentSlot" to pick the current slot if any and save it.
Auto-Save will also save the current slot, and Auto-Load will load the last current slot
To save a game you can just get the Save Manager and then call SaveGame to Slot
Save to Slot
Save into certain slot
Save Current Slot
