well...........
H is the first spawn point of that type you put down
Then you have, N, NE*, E, SE*, S, SW*, W, NW*
*Shown as blanks
These have to be rotated in the correct direction, so north would be pointing north (which is the default anyway), and east would be pointing east,
get it?
ps, he's something i've been wandering, if you have multiple spawn points pointing the same direction, do you spawn randomly between them?
