Forge Help

Hey guys!

I am a very avid forger and I need some help. I am not sure if I did it by accident, but in Halo 2 Forge I managed to create a script that will activate when you walk into a certain boundary (so if I walk on a specific 2x2 Block the door will start opening). Does anyone know how to create this same effect in Halo 5? I am trying to create an elevator that works simply by stepping in (it goes down) and then stepping out (it goes back to its original position).

Look up forge hub on YouTube, they have tutorials on how to set up triggers like that.
