[SCRIPT] Door locks behind you! [Solved]

[ethics]

So i wanted to do a script event:
If you go into a certain room. the door will slam shut behind you.
I have already done that.

But now I wanted to lock the door behind you so you can't escape the room anymore and have to search for another way (in my case a hatch in the ground).

I found nothing related to this on the internet. I don't know many script commands, just getting started with my first custom story.

I hope you can help me!
