How to reset the game to the main level after some minutes that no one is touching the screen

Hello, I’m quite new in UE and I’m developing an app for touch-screen (Windows touch) to explore a sailing ship model with a camera orbiting around the model (multi level, you can change level from ui buttons). You find the blueprint and the app interface below. I would the main level to restart or reset when no one is touching the screen for a couple of minutes…how could I do that?..I started with the Event LevelReset node but then?Thanks in advance for suggestions.

Add a float variable called “Timer” or something. Connect it all up like the picture. Then Set the Timer variable to 0 any time there is any user input. That’s just one way you can do it.
