[SCRIPT] Sliding Shelf

[FlawlessHappiness]

You need to use the shelf, that is called something with secret door.
There are 2. One of them is grabable, and it's probably not that one you want.
The other one is a bit higher, and it uses SetMoveObjectState.

Now you say it moves in the wrong direction. I'm pretty sure other people have had that problem too.
First try searching for it.
Secondly, try opening the model in the modeleditor, and check how it works. Then try to make it on the Z-axis instead.

For the books:
There's nothing to do. Those books are static, and if they were movable, it would look strange because that would be large squares of books, moving.
What you could do is, to try to make it look realistic with movable books and stuff that could be on this shelf.

For shelves and secret doors, use a lever. You cannot do it with a script area.

A script area should not be the problem. SetMoveObjectState does not change whether it's used by a lever or a script area. It doesn't change anything in the script, except for some parameters.
