Trigger a scene when an element is on top of other element like pacman game

I did the things Mark advised me to do. They work great!

But I still struggle with two other things:

  1. I can't figure out why, when I go back to the main scene, the book rotation stops working;
  2. Triggering Go To Time In Timeline didn't work as I expected, but I wrote about that in another thread.
