How do I pause a Layout, go to another, then resume the first Layout?

Im creating an educational game, wherein you play a side scroller and when you get to a certain point it cuts to another layout to answer a question. And then takes you back to the game.

So I'm trying to pause the first layout, and then resume it where it left off upon return?

A. Don't use a separate layout if you don't need to. You can use layers and visibility instead.

B. Use the persist behavior to keep object properties when switching layouts.

Pausing really depends on your project and what you need paused specifically. Generally speaking though, if you change layouts nothing is going to be happening on the previous layout so it's effectively paused by default.
