Actually, you can just add a single dimensional array as a property within the "location" class which holds 10 integers, each one corresponding to a particular direction. For example, the array could be:
{N,E,W,S,NE,NW,SE,SW,Up,Down}
For a particular room, the array might read:
{1,0,0,1,0,0,0,0,1,0} which means that he can move north, south and up, but not anywhere else.
