Monsters closed doors

menu
If a door is closed due to specific scenario rules, what happens if revealed monsters are stuck in a room with no enemies to attack?

Closed doors behave like walls. The monsters are still revealed, so they would still play a card at the beginning of each round, but, until the door is opened, they wouldn't be able to find a focus, and so would not move or attack and just perform any other abilities on their card, as per the normal rules.
