Hello everyone
ok so I added the self repair thing to my fortress
and it is working quite fine, but the thing is it is repairing it for free, what I want is to make it like isengard/minas tirith gates, it costs resources when you repair them, and if they are broken just a little, it repairs for little amount of resources, but if they are broken a lot, then the repairing costs alot
how do I do that resources thing, again, I have done everything but it is doing it for free.
thanks.
