I was working on a mining script before I left, not sure if you guys already have something similar or if there's any interest in it.
What it does is scan tiles and figures out where the mountain wall is, pathfinds to it, mines, and moves to the next 8x8 block. It will follow the edge of the mountain regardless of shape, completely automagically. All you need to do is have a rune marked next to a mountain, it'll recall there, mine until full, recall back and dump ingots. I think it's even got smelt on beetle support. But it's far from finished, a lot of hardcoded stuff that I used for testing and so on.
Is this something the community here would be interested in? Has it been done already? Mainly talking to the resident scripters since you need to be able to read and understand the script to make use of it in it's current shape.
