Say I have a piece that is oriented eastward. Can I use (sites Distance) to get all sites reachable by that piece given a restriction that, after each step, it may turn to the right (clockwise) or keep it's orientation? So I get all sites reachable by a piece that cannot turn to the left, basically. I'm specifically thinking of turning as adding 1 to its rotation, then do mod the number of orientations.
Edit: I just found out what I should have tried before asking. I must try to set the rotation inside (step (then …)). I still haven't tried it, but I'm in the process of understanding these things now.
