Hey, Basically I want the Payload cart to get to a certain part of the track (just before the last cap) and I want it to open the doors on the Red barn (shown below). Right now it's just a normal Trigger_Multiple that opens the doors when a player goes through the trigger. I assume it's definitely got something to do with the cart hitting a trigger_multiple which is connected to the doors. I just need to know how to do it properly. Any help would be great.
