Hmm. Right now I store the positions of my mobile piec elsewhere than in the world-list. Your function might be handy later on. I haven't yet decided if I want every actor of the world stored in the world (even if some of them might overlap), or store the mobile actors in a separate list.
Right now the thing about sokoban implementations that would interest me most is if you've done anything fancy to generate the output. Having an update of a 2d world scroll by ever so often makes it hard to track movement of a single character through this world. Did you work on that?
Since Arc is a language targeted for the web... have you considered the possibility of generating a web page for it, with maybe next >> and << prev links?
That might actually work, and just autorefresh the page every second or so :)
First priorities now are finishing the wandering algorithm for the animals so that they're no longer steered but steer themselves, and generalize the code I've some more so that adding more behaviours than just biting things is easy. I'll add the visuals-through webpage idea to that list :)
Sorry, not really. I just used a simple function to print out a 2-dimensional list and resized my terminal window so that the grid would be in the same place after every sequence of moves, which gives the illusion that the same grid is being redrawn.
