I want NPCs to try and follow roads as much as possible in my game. However roads in my game can be added/moved/removed by the player. Meaning I cant just set a certain penalty on areas that are not roads.
What I'm wondering is, is there some way to create an effect that is the opposite of penalty? i.e makes it MORE likely for the NPC to walk there, then I could put this on the road prefab and problem solved
