Grundkonzept

Die Sponge Economy API hat ein paar grundlegende Komponenten, mit denen Entwickler vertraut sein sollten:

  • EconomyService

  • Währung

  • Konten

  • Transaktionen

Der EconomyService

Der EconomyService ist die Basis der Economy API. Dieser wird verwendet um mit der Economy API zu interagieren, speichert zudem die dazugehörigen Währungen und bietet Methoden zum Account-Management an.

Warnung

Sponge stellt keine Standardimplementierung für den``EconomyService`` bereit. Es liegt an den Plugins selbst, die ‚Economy API‘ zu implementieren. Das heißt, dass du ein anderes Plugin brauchst, das diesen Service implementiert, oder dass du die ‚Economy API‘ selbst implementieren musst, wenn du von ihr Gebrauch machen möchtest.

Währung

The Currency object represents a form of Currency. Currency stores a display name (plural and singular), a symbol, the number of fractional digits, and whether the currency is the default currency for the economy. If the economy plugin chooses, it can support multiple currencies.

Konten

Accounts are used to store economy information about a specific player or other object (i.e. bank, business, entity). There are two account types in the Sponge Economy API:

Virtuelle Konten

Virtual accounts are tied to an identifier, which is stored as a string. Virtual accounts can be tied to almost anything, but are commonly used for things such as banks, or non-players. To get the id of a virtual account, use identifier().

Einzigartige Konten

Unique accounts are tied to a UUID, usually a player. To get the UUID of an unique account, use uniqueId().

Transaktionen

Transactions represent an account’s change in balance. There are currently three types of transactions:

  • Deposit: Occurs when an account has funds added to it

  • Withdraw: Occurs when an account has funds removed from it

  • Transfer: Occurs when an account exchanges funds with another account

When a transfer occurs, the EconomyTransactionEvent is fired. Using this event, you can get the TransactionResult. The TransactionResult stores data about the transaction that occurred, including:

  • Account involved

  • Currency involved

  • Amount of currency involved

  • Art der Transaktion

  • Ergebnis der Transaktion

You can view all possible transaction results on the ResultType JavaDocs page.
