I have an idea for a mod that is based upon your border changing, but I've been unable to find anything regarding this in the files - can anyone point me in the right direction?
Excellent information, can you describe the 'border closeness' also? I didn't understand what you meant.You might want to look at the tech that increases border size. It might have a call to the border itself that you can co-opt and play with. There are also modifiers on border closeness in the game so the calls in those files might also help.
