Function Documentation

adv_best_government()

void adv_best_government

(

struct player *

pplayer

)

Find best government to aim for. We do it by setting our government to all possible values and calculating our GDP (total ai_eval_calc_city) under this government. If the very best of the governments is not available to us (it is not yet discovered), we record it in the goal.gov structure with the aim of wanting the necessary tech more. The best of the available governments is recorded in goal.revolution. We record the want of each government, and only recalculate this data every ai->govt_reeval_turns turns.

Note: Call this before doing taxes!

adv_data_analyze_rulesets()

void adv_data_analyze_rulesets

(

struct player *

pplayer

)

Analyze rulesets. Must be run after rulesets are loaded, unlike _init, which must be run before savegames are loaded, which is usually before rulesets.

adv_data_city_impr_calc()

static void adv_data_city_impr_calc ( struct player *  pplayer, struct adv_data *  adv  )

static

Precalculates some important data about the improvements in the game that we use later in ai/default/daicity.c. We mark improvements as 'calculate' if we want to run a full test on them, as 'estimate' if we just want to do some guesses on them, or as 'unused' is they are useless to us. Then we find the largest range of calculable effects in the improvement and record it for later use.

adv_data_close()

void adv_data_close

(

adv_data_default()

void adv_data_default

(

pplayer

)

adv_data_get()

struct adv_data * adv_data_get	(	struct player *	pplayer,
		bool *	caller_closes
	)

Return a pointer to our data. If caller_closes is set, data phase will be opened even if it's currently closed, and the boolean will be set accordingly to tell caller that phase needs closing.

adv_data_phase_init()

bool adv_data_phase_init	(	struct player *	pplayer,
		bool	is_new_phase
	)

Make and cache lots of calculations needed for other functions.

Returns TRUE if new data was created, FALSE if data existed already.

Note: We use map.num_continents here rather than pplayer->num_continents because we are omniscient and don't care about such trivialities as who can see what.

FIXME: We should try to find the lowest common defense strength of our defending units, and ignore enemy units that are incapable of harming us, instead of just checking attack strength > 1.

adv_is_player_dangerous()

bool adv_is_player_dangerous	(	struct player *	pplayer,

There are some signs that a player might be dangerous: We are at war with them, they have done lots of ignoble things to us, they are an ally of one of our enemies (a ticking bomb to be sure), we don't like them, diplomatic state is neutral or we have cease fire.
