Function Documentation

◆ GetMaskOfAllowedCurrencies()

Currencies GetMaskOfAllowedCurrencies ( )

get a mask of the allowed currencies depending on the year

Returns: mask of currencies

Definition at line 128 of file currency.cpp.

References _currency_specs, CF_ISEURO, CF_NOEURO, Custom, End, BaseBitSet< Timpl, Tvalue_type, Tstorage, Tmask >::Set(), and TimerGameCalendar::year.

◆ GetNewgrfCurrencyIdConverted()

Currency GetNewgrfCurrencyIdConverted ( uint8_t grfcurr_id )

Will return the ottd's index correspondence to the ttdpatch's id.

If the id is bigger than the array, it is a grf written for ottd, thus returning the same id. Only called from newgrf.cpp

Parameters

grfcurr_id currency id coming from newgrf

Returns: The corrected index, or Currency::End when invalid.

Definition at line 118 of file currency.cpp.

◆ ResetCurrencies()

void ResetCurrencies ( bool preserve_custom )

Will fill _currency_specs array with default values from _origin_currency_specs Called only from newgrf.cpp and settings.cpp.

Parameters

preserve_custom will not reset custom currency

◆ _currency_specs

EnumIndexArray<CurrencySpec, Currency, Currency::End> _currency_specs

Array of currencies used by the system.

◆ _origin_currency_specs

const EnumIndexArray<CurrencySpec, Currency, Currency::End> _origin_currency_specs

static

The original currency specifications.

◆ _ttdpatch_to_ottd_currency

const Currency _ttdpatch_to_ottd_currency[]

Initial value:

                                          = {
  Currency::GBP,
  Currency::USD,
  Currency::FRF,
  Currency::DEM,
  Currency::JPY,
  Currency::ESP,
  Currency::HUF,
  Currency::PLN,
  Currency::ATS,
  Currency::BEF,
  Currency::DKK,
  Currency::FIM,
  Currency::GRD,
  Currency::CHF,
  Currency::NLG,
  Currency::ITL,
  Currency::SEK,
  Currency::RUR,
  Currency::EUR,
}

This array represent the position of OpenTTD's currencies, compared to TTDPatch's ones.

When a grf sends currencies, they are based on the order defined by TTDPatch. So, we must reindex them to our own order.
