Can't name keys and other problems

[Litronom]

I guess you put out a "Sign" area, you find those in the list with scriptareas. just put it to cover the door, and edit the entity options there, make a category "signs" and call it "library" (In the Extra_english) so when the player looks at that signbox it will say "library" or "library door"

And if its bothersome after you've unlocked the door, put set entity false to disable it, along with the script to unlock the door,

If you place a sign area in front of the door, you cant interact with the door.
So, if you want to unlock it with the key, scale the sign area up to the doors size and use AddUseItemCallback in connection with the sign area.
