I’ve got a question for you.
Can I save the actually loaded Scene in the Runtime ?
I need it for my Game-In Level Editor.
As far as I know this isn’t possible, the thing you would want to do is:
Create a level editor which would write out all data about the stuff in the scene
Create a level loading scene which would take that data and build the scene again.
On how to save that data, it could be done using a number of options but that would depend on the complexity of your scenes.
Personally for smaller scenes like 2D levels, I like to use json and just parse everything I need to spawn, their locations and maybe other variables that I would need.
