The reference says that this proc takes obstacles into account. Well, there's a step_to and step_towards for going forward, but there's no way to make them step away without taking obstacles into account. I could really use this for Echelon, since the pieces need to be pushing eachother around, and when I want them to move away from the edge of the board, I can't get them to push any pieces that are in the way. Any chance of getting a get_step_away proc that doesn't take obstacles into account?
