I started working on a cp map based in a snowy area, were I plan to have a two suspended cars (sort of like a ski lift, but more enclosed) that run in a loop, going from cp 2 to cp 4. I came up with the idea when I was playing with 'elevators' earlier, which use the door_func but instead of moving out of the player's way, they move with the player to push them. I just realized the problem with this however, which is that my elevator system can only move in one direction, and it is dependent on a player to activate it. With the trams I want the two cars moving in a more-or-less rectanglular loop 24/7, whether players are on the cars or not. Essentially, I'm trying to get an object (or a group of objects) to move in a continuous loop along a path. I don't know if Hammer Editor can handle paths though, since I did a couple quick searches but didn't find anything related to path constraints. It seems like there should be something to make it work though, because the bombs on push the cart maps do something similar(granted they don't run in loops, but they do run on a path). Is there a way to make this work, or should I scrap the idea?
