Text label shows different messages in the direction you come from

I’m trying to make or find a script in which when a player passes over a part a text label will appear with “Now Entering: The Unknown” and then if you were to come back in you would instead get “Now Entering: Safe Zone”

I’m attempting to get something similar to the Zombie game “Alone” at 2:47.

In this scenario, I would use a transparent box to represent the zone and check if the player is inside of the zone by using magnitude.
