And Player usually passes the message on to the player costume, so you 
have to know the internals of the costume to know what messages it have 
implemented. Costume is most usually a subclass of morph.

Sound is unusual as it does not have a morphic costume and the only 
visual representation is tiles.

I recommend playing around and testing stuff. Ask questions here and if 
you could document stuff you learn it would be great :-)

Its easy to add the scripts for most stuff. I spend most of the time 
understanding the internals of the morph I want to script, like finding 
the access point and what kind of data types are sent.
