◆ adv_settlers_road_bonus()

adv_want adv_settlers_road_bonus	(	const struct civ_map *	nmap,

		struct tile **	best_tile,
		struct pf_path **	path,
		struct settlermap *	state
	)

Finds tiles to improve, using punit.

The returned value is the goodness of the best tile and action found. If this return value is > 0, then best_tile indicates the tile chosen, bestact indicates the activity it wants to do, and path (if not NULL) indicates the path to follow for the unit. If 0 is returned then there are no worthwhile activities available.

completion_time is the time that would be taken by punit to travel to and complete work at best_tile

state contains, for each tile, the unit id of the worker en route, and the eta of this worker (if any). This information is used to possibly displace this previously assigned worker. if this array is NULL, workers are never displaced.
