How to make Script puzzles?

[HumiliatioN]

From what i know from PAWN, is that you can make your own.

Just make a book collide with a Scriptarea (Like said above)
If that happened, just do something like: BooksPulled == 1);

No, I have NO idea how it works in Amnesia. but that should be a base.

Ugh. I dont have any clue how to do that?
