I don't know of many things that can be damaged by dwarves or destroyed walking over them, but two important ones that can be are spider webs and saplings. A simple solution is some options on the orders screen: Dwarves avoid/ignore webs/saplings. If one of these options is set to avoid, the pathing system treats tiles with a web/sapling as restricted traffic tiles. If you don't mind your dwaves taking a zigzag path through the forest, you'll have better regrowth of trees, and the same for caves and webs.

I certainly like this better than manually setting the pathing weights for each sapling you notice that you want to keep. However, I think "restricted" is a bit excessive here; just set them to "light" traffic and that should be entirely adequate.

[OneRaven]

Low traffic would be fine as well. Restricting individual saplings sucks, though.

e: Shrubs are also killed by traffic. While not as useful to the average fortress as saplings->trees, "Avoid Shrubs" should probably be an option too.

What also be neat, is if you can set pathing based dorf activity, and make it so that one square is for one direction.

Like making a one way street, or making a three wide hallway, where the middle square is for dorf hauling stuff.

The one-way-tile is an interesting idea, but how would you deal with dwarves attempting to path perpendicular/diagonally to the path?

I was thinking they could work like this:

Code: [Select]

hhh
n^n
lll
So for a tile oriented up, moving upwards in any way acts as if they're high-traffic, sideways is normal, and backwards is low.

[Warlord255]

A setting for traffic-marking shrubs, saplings and webs (each) would be very nice.

That said, expect lots of grass-trampling for the sake of FPS.

The problem with the one way tile is it throws out the concept of the connectivity map, since the pathing algorthm would now have to be aware of a direction, and not just a connection. Right now path restrictions just adds a precieved lenght to any path that has that tile, so any path that has a restricted tile simply adds 100 (or whatever) to any path that has that tile. Dorfs go around that tile because they want to use the shortest path. Since A* uses a simple fill to calculate best path you would need the pathing algorythm to hold data not just for individual tiles (what we have now) but also for adjacent tiles. This is also the problem multi-tile cretures have, since they also need to calculate adjacent tile data.

Grass trampling is a complete mess right now. If anything, it should be disabled entirely until it's reworked

[MMad]

Nice little suggestion.
