Save Level And Widget

How do i save my game only level and widget so like a save and load system.

hey there !
you need to use the savegame system for that :
here is the documentation :

and a tutorial:

But i only want to save the level and the widget nothing else and there isn’t really a var for levels like he does in his vid.

what do you want to achieve exactly ? save the level the player is in ? if it s that, you can use the level name as a variable, save it and restoring it using the savegamesystem.
for your widget, what do you want to save exactly ?
