You can't script .dif files.
That reminds me: I remember, in v0002, there was a code to make objects spin. And we'd put the whole bedroom into it... Hilarious with the bedroom constantly spinning around us, although it got annoying and scary.

Shadows do not cast onto DTS and the lighting will look weird. I say just either leave it open or keep it closed.
Or, keep it closed and make those door windows breakable.
