Scripting an on/off radio

[TheGreatCthulhu]

@Amn: You know what you could try? You could create one huge script area that encompasses entire level, and then add a use item callback on that - if it's possible to do when you're standing inside the script area itself (didn't test). The player experience would be: use the cellphone to interact with "the air". If it's possible, than it would work out rather nicely, for what you want to do, I think.
