I have a gate. I want to only be able to enter the gate from the south area of it(the icon), not from any other direction. Is there any way I can go about doing this?

  Enter(mob/M)   //  Calls when an object tries entering the turf.
    if(!ismob(M)) //  If a non-/mob tries to enter, it is DOOMED!
        del M

    if(M.dir & NORTH)  //  This is assuming that the gate is pointing southwards; a person entering northwards (N, NE, NW) can access the gate. If you want to check if they specifically come from the south, do M.dir == North
          M.loc = locate(THE VOID)
    return 0  // Deny access
