◆ city_desirability()

struct cityresult * city_desirability	(	struct ai_type *	ait,
		struct player *	pplayer,
		struct unit *	punit,
		struct tile *	ptile
	)

Calculates the desire for founding a new city at 'ptile'. The citymap ensures that we do not build cities too close to each other. Returns NULL if no place was found.

◆ cityresult_fill()

static struct cityresult * cityresult_fill	(	struct ai_type *	ait,

static

Fill cityresult struct with useful info about the city spot. It must contain valid x, y coordinates and total should be zero.

We assume whatever best government we are aiming for.

We always return valid other_x and other_y if total > 0.

static struct cityresult * find_best_city_placement	(	struct ai_type *	ait,
		struct unit *	punit,
		bool	look_for_boat,
		bool	use_virt_boat
	)

static

Find nearest and best city placement or (TODO) a city to immigrate to.

Option look_for_boat forces us to find a (real) boat before considering going overseas. Option use_virt_boat allows to use virtual boat but only if punit is in a coastal city right now (should only be used by virtual units). I guess it won't hurt to remove this condition, PF will just give no positions. If (!look_for_boat && !use_virt_boat), will not consider placements overseas.

Returns the better cityresult or NULL if no result was found.

static

Find nearest and best city placement in a PF iteration according to "parameter". The value in "boat_cost" is both the penalty to pay for using a boat and an indicator (boat_cost != 0) if a boat was used at all. The result is returned in "best".

Return value is a 'struct cityresult' if found something better than what was originally in "best" was found; else NULL.
