How do i 'cook' a teleporter to be working in game

Another question.

I have a working teleported ‘pillars’ in game and able to use it level-based.

  1. How do i scripting in the object’s graph itself
  2. How do i assign ‘Names’ on each pillar to facilitate the teleporting
  3. Can i have a interaction menu by which if there are alot of pillars, i can assigned a destination pillar to the master pillar

All the necessary files are in the folder.

Thank you
