Help with Teleport Script for Puzzle Game

Hello everyone! I had a specific question about a teleport script for Unity. I have a very basic script you go through this door to get to this destination. If I wanted for example to have a teleport go through a door to another door to another door does anyone have a javascript I could use for that? A better example I have is if you played the old school Pokemon games they had a gym leader boss where you would go through one platform to another one and you had to figure out the path to get to the gym leader. If I'm making any sense I really appreciate this help I'm not an advanced scripter for Unity just yet. Thanks for the help!
