Function Documentation

adv_calc_cultivate()

static adv_want adv_calc_cultivate ( const struct city *  pcity, const struct tile *  ptile  )

static

Calculate the benefit of cultivating the given tile.

The return value is the goodness of the tile after the cultivating. This should be compared to the goodness of the tile currently. (see city_tile_value(); note that this depends on the AI's weighting values).

adv_calc_extra()

static adv_want adv_calc_extra ( const struct city *  pcity, const struct tile *  ptile, const struct extra_type *  pextra  )

static

Calculate the benefit of building an extra at the given tile.

The return value is the goodness of the tile after the extra is built. This should be compared to the goodness of the tile currently. (see city_tile_value(); note that this depends on the AI's weighting values).

This function does not calculate the benefit of being able to quickly move units (i.e., of connecting the civilization). See road_bonus() for that calculation.

adv_calc_plant()

static adv_want adv_calc_plant ( const struct city *  pcity, const struct tile *  ptile  )

static

Calculate the benefit of planting to the given tile.

The return value is the goodness of the tile after the planting. This should be compared to the goodness of the tile currently. (see city_tile_value(); note that this depends on the AI's weighting values).

adv_calc_rmextra()

static adv_want adv_calc_rmextra ( const struct city *  pcity, const struct tile *  ptile, const struct extra_type *  pextra  )

static

Calculate the benefit of removing an extra from the given tile.

The return value is the goodness of the tile after the extra is removed. This should be compared to the goodness of the tile currently. (see city_tile_value(); note that this depends on the AI's weighting values).

adv_calc_transform()

static adv_want adv_calc_transform ( const struct city *  pcity, const struct tile *  ptile  )

static

Calculate the benefit of transforming the given tile.

The return value is the goodness of the tile after the transform. This should be compared to the goodness of the tile currently. (see city_tile_value(); note that this depends on the AI's weighting values).

initialize_infrastructure_cache()

void initialize_infrastructure_cache

(

struct player *

pplayer

)

Do all tile improvement calculations and cache them for later.

These values are used in settler_evaluate_improvements() so this function must be called before doing that. Currently this is only done when handling auto-settlers or when the AI contemplates building worker units.
