"..more towards what you're after"
Well, that's what I suggested you could settle for, but with 1 var you can lose the separate backgrounds' positioning and the overlap checking
@Annisa12 Variables are worth reading up on anyway, they'll open up possibilities/simplify stuff.. and are often essential. The manual will explain better than me, but in short, they are just stored values of number or text.
In this context what I was getting at, was a global text variable:
on touching the slide button for day/night, set that variable to "Day" or "Night"
and then in place of the 'is overlapping DayBackground' you can have 'if variable = "Day"'
or 'if variable = "Night"'
But anyways, not a big deal if this is all the project entails, but as it gets more complex, you'll probably want to start using them.
