Variable Documentation

◆ DEF_CARGO_SCALE

const int DEF_CARGO_SCALE = 100

static

Default value of town_cargo_scale/industry_cargo_scale.

Definition at line 41 of file economy_type.h.

◆ INITIAL_LOAN

const int64_t INITIAL_LOAN = 100000

static

The size of loan for a new company, in British Pounds!

Definition at line 210 of file economy_type.h.

Referenced by DoStartupNewCompany().

◆ INVALID_PRICE_MODIFIER

const int INVALID_PRICE_MODIFIER = MIN_PRICE_MODIFIER - 1

static

Definition at line 231 of file economy_type.h.

◆ LEVELCROSSING_TRACKBIT_FACTOR

const uint LEVELCROSSING_TRACKBIT_FACTOR = 2

static

Multiplier for how many regular track bits a level crossing counts.

Definition at line 236 of file economy_type.h.

Referenced by AfterLoadCompanyStats(), CmdBuildRoad(), CmdBuildSingleRail(), CmdConvertRail(), CmdRemoveSingleRail(), and RemoveRoad().

◆ LOAN_INTERVAL

const int LOAN_INTERVAL = 10000

static

The "steps" in loan size, in British Pounds!

Definition at line 208 of file economy_type.h.

Referenced by CmdDecreaseLoan(), CmdIncreaseLoan(), CmdSetCompanyMaxLoan(), DoStartupNewCompany(), CompanyFinancesWindow::GetWidgetString(), and RecomputePrices().

◆ LOCK_DEPOT_TILE_FACTOR

const uint LOCK_DEPOT_TILE_FACTOR = 2

static

Multiplier for how many regular tiles a lock counts.

Definition at line 242 of file economy_type.h.

Referenced by AfterLoadCompanyStats(), CmdBuildShipDepot(), DoBuildLock(), and RemoveLock().

◆ 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 39 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.

Definition at line 222 of file economy_type.h.

Referenced by AddInflation(), and AfterLoadGame().

◆ MAX_LOAN_LIMIT

const int64_t MAX_LOAN_LIMIT = 2000000000

static

The max amount possible to configure for a max loan of a company.

Definition at line 212 of file economy_type.h.

Referenced by CmdSetCompanyMaxLoan().

◆ MAX_PRICE_MODIFIER

const int MAX_PRICE_MODIFIER = 16

static

Definition at line 230 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 33 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.

See also: MAX_INFLATION

Definition at line 229 of file economy_type.h.

Referenced by SetPriceBaseMultiplier().

◆ ROAD_DEPOT_TRACKBIT_FACTOR

const uint ROAD_DEPOT_TRACKBIT_FACTOR = 2

Definition at line 238 of file economy_type.h.

Referenced by CmdBuildRoadDepot(), and CmdConvertRoad().

◆ ROAD_STOP_TRACKBIT_FACTOR

const uint ROAD_STOP_TRACKBIT_FACTOR = 2

static

Multiplier for how many regular track bits a bay stop counts.

Definition at line 240 of file economy_type.h.

Referenced by CmdBuildRoadStop(), CmdBuildRoadWaypoint(), CmdConvertRoad(), RemoveRoadStop(), and RemoveRoadWaypointStop().

The max score that can be in the performance history.

The scores together of score_info is allowed to be more!
