I now have industries and trucks, and the trucks have pathfinding. In the screenshot below, red dots are industries (can be anything from a grain farm to a food store) and the blue dot is a truck.
I’m currently trying to figure out how the user interface should work exactly. My original idea will be quite a pain to implement I believe, so I’m trying to figure out if there’s any simpler approach. In the mean time, I will probably add lists at each industry that shows available/desired resources.
