This enum gives the currencies a unique id which must be maintained for savegame compatibility and in order to refer to them quickly, especially for referencing the custom one. More... |
Functions | |
uint64 | 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=true) |
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. | |
byte | GetNewgrfCurrencyIdConverted (byte grfcurr_id) |
Will return the ottd's index correspondence to the ttdpatch's id. |
Variables | |
static const int | CF_NOEURO = 0 |
Currency never switches to the Euro (as far as known). | |
static const int | CF_ISEURO = 1 |
Currency is the Euro. | |

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
grfcurr_id | currency id coming from newgrf |
