Circle fish help

Question

hey i have a project and i need help with coding some parts. im supposed t oadd a CircleFish to the Marine Bio case study. this fish will always try to move up, then diagonally to the right, eventually moving in a circle.
Rules for Circle Fish Movement:
The Circle fish alternates between moving forward and to the right. It goes one cell forward, if possible. Next it moves diagonally to the right if that cell is empty, turning right at the same time. If either type of move is blocked because the target cell is not empty, then the CircleFish stays in palce but turns right. Whenever a CircleFish turns, it attempts to move forward next.
i can't figure out how to code the diagonall part
     protected Location nextLocation()
        Environment env = environment();
        Location oneInFront = env.getNeighbor(location(), direction());
        Location twoInFront = env.getNeighbor(oneInFront, direction());
        Debug.println("  Location in front is empty? " +
                        env.isEmpty(oneInFront));
        Debug.println("  Location in front of that is empty? " +
                        env.isEmpty(twoInFront));
        if ( env.isEmpty(oneInFront) )
            if ( env.isEmpty(twoInFront) )
                return twoInFront;
            else
                return oneInFront;
        // Only get here if there isn't a valid location to move to.
        Debug.println("  CircleFish is not moving.");
        return location();
    }if you need the other pieces of my code like the constructors i could paste them too. i just need help w/ direction because that code i wrote only to check if the space is empty. then it returns the circle fish's current location. plz help!

as i said before, this one wasnt updated. i did more
work and posted a new topic. whats so wrong?It cuts down on the effectiveness of responses, leads to people wasting their time answering what others have already answered, makes for difficult discussion, and is generally just annoying and bad form.
