I am working on an infection map. In this map, there are 4 stages. What I need to know is how to make doors to separate these stages. For example, at the 2 minute mark, something would spawn that would cause the door to open. I only it so that the doors can be opened at a certain time. I was thinking of spawning a Grav Lift at a certain time to lanuch you over the wall, but that isn't interesting at all. Can someone give me some suggestions?
I actually know how to make a fully functioning door that opens using a switch, and can be re-closed (well, respawns), and it doesn't use gravity lifts. I won't be on for a while (a week roughly) if you have patience to wait a week then I most definitley can help.
