Use spot command.
I dunno if you use Writer’s portal (which is the best way for advance coding) or mobile. But anyway.
You pick the character you need to exit. Take a note on her current spot position (1.193 213 -4)
Now you want to move her with the Spot Helper outside of the screen. There. Well, you will move character even further, but check her spot position. The second number is now in negative. (1.193 -36 8)
Just remember to keep the third number the same (if she walks straight of course) and don’t forget to put timing.
