The traffic management part of the pathfinding is very interesting to me.
The reason is that I like having 2 entrances to my fort.
One for the trade depot
One for everything else
That way I can mine traps on the external entry to the main door whilst leave the trade depot one free and just mining internally for that one.
I always used to have it at my front door but then due to trade caravans hating to make their way past traps, i came up with this idea.
It is great, if I can get the traffic management right.
As otherwise, my dorfs use either entrance and it doesn't let me be effective when i want to LOCK the caravan in when they arrive to avoid thieves... as when i do, i have a stream of haulers and if i get the timing wrong, broken bodies!
The only way to solve this is make the internal corridor to the Depot high traffic and the space around the external part of the depot door restricted traffic. I then have to do this on all slops above to avoid them skirting past my zoning of traffic. It works sometimes, sometimes it fails or just looks silly when they go out of their way to still find a way in.
Its not impossible to make work, just clunky.
So i wonder, is there a way (or should there be a way) to have a forbidden traffic zone instead of just difficult.
That way I just zone the 3 spots at the back door and my dwarves will never be able to go through that spot (just as if it was blocking terrain) and would HAVE to find a way through the pathing i want.
Just seems like this is missing from the options and wondered why... or if there is a wayaround?
