What dir number is what direction? 9 is northwest I know, but what're the others?

I'm modifying the dir of turfs to allow for less icon_states.
just go into the compiler and do something like:

mob/verb/dir_nums()
src<<NORTH
src<<SOUTH
src<<EAST
src<<WEST
src<<NORTHEAST
src<<NORTHWEST
src<<SOUTHEAST
src<<SOUTHWEST


and you'll answer your own question
In the little window labeled "Object" below the minimap, right-click on the object and select "Generate Instances from Directions".
