Enumerations | |
enum | { CURR_GBP, CURR_USD, CURR_EUR, CURR_YEN, CURR_ATS, CURR_BEF, CURR_CHF, CURR_CZK, CURR_DEM, CURR_DKK, CURR_ESP, CURR_FIM, CURR_FRF, CURR_GRD, CURR_HUF, CURR_ISK, CURR_ITL, CURR_NLG, CURR_NOK, CURR_PLN, CURR_RON, CURR_RUR, CURR_SIT, CURR_SEK, CURR_YTL, CURR_SKK, CURR_BRL, CURR_EEK } |
These enums are only declared in order to make sens out of the TTDPatch_To_OTTDIndex array that will follow Every currency used by Ottd is there, just in case TTDPatch will add those missing in its code. | |
Functions | |
byte | GetNewgrfCurrencyIdConverted (byte grfcurr_id) |
Will return the ottd's index correspondance to the ttdpatch's id. | |
uint | GetMaskOfAllowedCurrencies () |
get a mask of the allowed currencies depending on the year | |
void | CheckSwitchToEuro () |
Verify if the currency chosen by the user is about to be converted to Euro. | |
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. | |
StringID * | BuildCurrencyDropdown () |
Build a list of currency names StringIDs to use in a dropdown list. | |
Variables | |
static const CurrencySpec | origin_currency_specs [NUM_CURRENCY] |
CurrencySpec | _currency_specs [NUM_CURRENCY] |
const byte | TTDPatch_To_OTTDIndex [] |
This array represent the position of OpenTTD's currencies, compared to TTDPatch's ones. |

byte GetNewgrfCurrencyIdConverted | ( | byte | grfcurr_id | ) |
Will return the ottd's index correspondance 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
grfcurr_id | currency id coming from newgrf |

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.
preserve_custom | will not reset custom currency (the latest one on the list) if ever it is flagged to true. In which case, the total size of the memory to move will be one currency spec less, thus preserving the custom curreny from been overwritten. |

const byte TTDPatch_To_OTTDIndex[] |
{ CURR_GBP, CURR_USD, CURR_FRF, CURR_DEM, CURR_YEN, CURR_ESP, CURR_HUF, CURR_PLN, CURR_ATS, CURR_BEF, CURR_DKK, CURR_FIM, CURR_GRD, CURR_CHF, CURR_NLG, CURR_ITL, CURR_SEK, CURR_RUR, CURR_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.
