Price

enum Price

Enumeration of all base prices for use with Prices.

The prices are ordered as they are expected by NewGRF cost multipliers, so don't shuffle them.

Definition at line 89 of file economy_type.h.

PriceCategory

enum PriceCategory

Categories of a price bases.

Enumerator
PCAT_NONE	Not affected by difficulty settings.
PCAT_RUNNING	Price is affected by "vehicle running cost" difficulty setting.
PCAT_CONSTRUCTION	Price is affected by "construction cost" difficulty setting.

Definition at line 198 of file economy_type.h.

ScoreID

enum ScoreID

Score categories in the detailed performance rating.

Enumerator
SCORE_TOTAL	This must always be the last entry.
SCORE_END	How many scores are there..
SCORE_MAX	The max score that can be in the performance history.

Definition at line 60 of file economy_type.h.

Variable Documentation

MAX_CARGO_SCALE

const int MAX_CARGO_SCALE = 300

static

Maximum allowed value of town_cargo_scale/industry_cargo_scale.

Above 340, callback-based industries would produce more than once per day, which GRFs do not expect. Towns use the same maximum to match.

Definition at line 38 of file economy_type.h.

MAX_INFLATION

const uint64_t MAX_INFLATION = (1ull << (63 - 32)) - 1

static

Maximum inflation (including fractional part) without causing overflows in int64_t price computations.

This allows for 32 bit base prices (21 are currently needed). Considering the sign bit and 16 fractional bits, there are 15 bits left. 170 years of 4% inflation result in a inflation of about 822, so 10 bits are actually enough. Note that NewGRF multipliers share the 16 fractional bits.

MAX_PRICE_MODIFIER

Definition at line 229 of file economy_type.h.

MIN_CARGO_SCALE

const int MIN_CARGO_SCALE = 15

static

Minimum allowed value of town_cargo_scale/industry_cargo_scale.

Below 13, callback-based industries would produce less than once per month. We round up to 15% because it's a nicer number. Towns use the same minimum to match, and because below this small towns often produce no cargo.

Definition at line 32 of file economy_type.h.

MIN_PRICE_MODIFIER

const int MIN_PRICE_MODIFIER = -8

static

Maximum NewGRF price modifiers.

Increasing base prices by factor 65536 should be enough.
