Drawing the road

(Machine translation warning). Right now, I can use the map to freely move wherever I want. In the future, I'd like to see areas I can't enter for various reasons (a cliff, a precipice, lava). I also like the idea of ​​adding route lines, either hand-drawn or generated, that would represent a road, a path, or something similar. So I could say, "I'm following the sign along the road toward Rucheynaya Village." And instead of randomly navigating to a location along the way, I'd simply move along the pre-drawn route.
