I like to use interactive portals, as they open lots of complicated architectural possibilities.
However.
One limitation of these portals, is that the dormant monsters do not see you through them.
If you shoot (make a sound) in the area the portal is connected, this does wake the monster
up and it begins to act normally.
I have tried to use Thing_Activate (Among some others) in a script, so when player crosses a linedef the enemies would
be alert etc. As I do not want to force the player to make a sound.
But the enemies just stay dormant. Thing_Activate does not wake the enemies. (set them in their chase state.)
Any solution to make the enemies active so that you wouldn't encounter a blind monster standing in front of you on
the opposite end of a portal?

(One way could be to make the monsters patrol between points. But I would assume that
the same problem would persist as if they are in the other side of the portal, while patrolling, they still would not see the player
even if they would face directly to him.)
Thx in advance for any help!
