void  optionsOfDirection()
 {
     getDirection();
     int chooseADirection = Greenfoot.getRandomNumber(4);
     switch (chooseADirection)
     {
         case goUp: setDirection("up");
         break;
         case goDown: setDirection("down");
         break;
         case goLeft: setDirection("left");
         break;
         case goRight: setDirection("right");
         break;
     }
}
Where getDirection determines the direction you're going

Please show the code for the 'getDirection' method. If all it does is determine the direction and does not actually change anything, then I cannot see how it would have any influence on what the 'optionsOfDirection' method is doing. Also, lines 4 though 15, which is the final code in the method, will randomly choose any of the possible directions, regardless of which direction it was previously facing.
