Small note: When coming from NORTH/NORTHEAST/NORTHWEST M.dir is SOUTH/SOUTHWEST/SOUTHEAST

if(M.dir == NORTH || NORTHEAST|| NORTHWEST)


NORTHEAST and NORTHWEST are true; therefore, the if() statement continues regardless of direction. You need to keep saying M.dir == NORTHEAST || M.dir == NORTHWEST etc.

However, bitwise math would be better for this!

if(M.dir&NORTH) //if they have north in their direction
