you mean the Lua command to allign a character in a certain position?
That should be:
Characters["Name"].Direction = 0
(0 = right, 90 = up, ...)
Kind of, but they said they want to align the character to the mouse cursor, but that requires a bit of math & I can't remember what it is off the top of my head & the wiki server currently appears to be down - I'm sure I posted an example on there ages ago.
