how to make monsters open other doors

[kassianoaguiar]

What is the flag that makes the monster manage to open and insist on opening any door? (my case is the ports that open sideways in UDMF format).

 

NOTE:
In this UDMF format I have already put on the opening doors that the monster that touches the door opens the door BUT THE MONSTER DOES NOT INSIST ON GOING THROUGH THE DOOR AND YES IT KNOCKS AND COMES BACK...

 

What to do?!?

The best thing I could recommend is to make a door opening line (to be activated by monster walkthrough) in some distance (maybe 64-128 units) far from the door.
