Filters Flag Carrier

[Cereal_Killer]

Is there anyway to add a filter so that when a player has the flag he is unable to take certain routes. For example, there are 3 paths but when a player has the flag he can only take one of the paths. Any help?? please

See http://forums.tf2maps.net/showthread.php?t=538, that has a door that only opens for the flag carrier but it could be modified to be the opposite. You could also modify that so it is a func_brush instead of a door, and the wall is only solid when the flag is nearby. A different option might be to use a func_respawnroom brush to make players drop the flag if they try and enter a certain area.
