Function Documentation

◆ GetMaskOfAllowedCurrencies()

uint64_t GetMaskOfAllowedCurrencies ( )

get a mask of the allowed currencies depending on the year

Returns: mask of currencies

Definition at line 124 of file currency.cpp.

References _currency_specs, CF_ISEURO, CF_NOEURO, CURRENCY_CUSTOM, CURRENCY_END, SetBit(), CurrencySpec::to_euro, and TimerGameCalendar::year.

◆ GetNewgrfCurrencyIdConverted()

byte GetNewgrfCurrencyIdConverted ( byte 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

Definition at line 115 of file currency.cpp.

References lengthof, and TTDPatch_To_OTTDIndex.

◆ 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

Definition at line 159 of file currency.cpp.

◆ TTDPatch_To_OTTDIndex

const byte TTDPatch_To_OTTDIndex[]

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.
