I am working on a map where i want it so when red caps, a door opens for blu so they have a new entrance to the point and vice versa. Can anyone teach me how?
unlock and lock doors set to specific capture points, http://tf2maps.net/threads/valve-maps-decompiled.5952/ is a good place to understand the I/O set ups
First, put down a logic_relay near your point so that you can find it. The logic_relay is optional but really helps keep your logic under control. Next, name it something you can remember easily, for example i'll call mine "relay_capA" Go to the logic_relay's "Outputs" tab and add a new output to open your door: Lastly, go to the control point's "Outputs" tab and add an output to trigger the relay: (Your cap point name, and the team who captures it, will obviously be different) Alternately, you can bypass the logic_relay entirely and add an output to open the door directly from the capture point, but if you want your capture point to do multiple things then the logic_relay will help you keep them organized. Just think of it like a baton passing race.
Yes, you'd just have to add another output on the logic_relay that targets another door, and another output on the team_control_point with "my output named" OnCapTeam2, along with OnCapTeam1. That's to make it so it's symmetrical, which a KOTH map should be.
