[SCRIPT] The books script

[The chaser]

So, I'm making a scene that requires a script. This is the situation:

For a reason I'm not going to tell, I want that when the books are touched (or the player grabs them and throws them) something happens.
The problem is, there are too much books, and making a single callback for each one would be a painful process.

Once I readed someone that wanted the same, more or less. I don't remember the thread, but I know it is something of for. How could I do it?
