I took the liberty to add a small bit to the script above so it also includes the possibility of locking the doors.

Code:

/* Filename:           door_auto_close System:             miscellaneous Author:             WizardStorm Think Group (Development@WizardStorm.com) Date Created:       Oct 7th, 2006. Summary: Automatically shuts oDoor1 after an set amount of time. If oDoor1 is connected to oDoor2 via a transition, it will close oDoor2 at the same time. By default, doors close after 30 seconds, however you can override this by setting a local float variable on the door called AUTO_SHUT_DELAY. If AUTO_SHUT_DELAY equals -1.0, the door will never auto close. ----------------- 05.03.07 Hellcow Lock door function added. Set a (int) variable on the door named LOCK_DOOR with the value of 1 and the door will lock when it closes. ----------------- */ void main() {    object    oDoor1          = OBJECT_SELF;    object    oDoor2          = GetTransitionTarget(oDoor1);    float   fShutDefault   = 30.0;    float     fShutDelay       = GetLocalFloat(oDoor1, "AUTO_SHUT_DELAY");        if(fShutDelay == -1.0)       return;    else if(fShutDelay == 0.0)       fShutDelay = fShutDefault;           AssignCommand(oDoor1, DelayCommand(fShutDelay, ActionCloseDoor(oDoor1)));    AssignCommand(oDoor2, DelayCommand(fShutDelay, ActionCloseDoor(oDoor2))); if (GetLocalInt(OBJECT_SELF, "LOCK_DOOR"))     SetLocked(OBJECT_SELF, TRUE);     }
