public class Card extends Entity implements HasChooseOneActions
The Card class is an entity that contains card information.

Cards are typically in the hand, deck or graveyard. They are playable from the hand or as hero powers. They may be created by other cards. Like all entities, they have attributes and are mutable.

  • Method Details

    • minion

      public Minion minion()
      Creates a minion from the attributes written on the card.

      By default, all the attributes written on the card except those contained in IGNORED_MINION_ATTRIBUTES are copied onto the minion created here. The Attribute.REMOVES_SELF_AT_END_OF_TURN attribute is also removed if it was present on the card.

      Text is applied using the applyRace(Actor) method, which works for all actors.

      Returns:
      A new Minion instance.

      public Hero hero()

    • clone

      public Card clone()
      Clones a card's base fields, like name and description, and its current attributes. The entity ID and location match the source object and are not cleared. getCopy() is typically more appropriate choice for when copies of cards are needed.

      Returns:
      An exact clone.

    • getBaseManaCost

      The base mana cost of a card.

    • getCardId

      public String getCardId()
      Gets the card's ID as it corresponds to the card catalogue. This is the base definition of the card.

      The hero classes (the gang)

    • getCopy

      public Card getCopy()
      Gets a copy of the card with some attributes like its attack or HP bonuses and mana cost modifiers removed. The ID and owner is set to unassigned.

      Typically you should use the GameLogic.receiveCard(int, Card) method in order to put a copy into e.g. the player's hand.

      Take a look at its logic to see how to assign an ID and an owner to a card for other uses of copies. A copy can become valid for play like this: Card copiedCard = card.getCopy(); int owningPlayer = player.getId(); copiedCard.setId(getGameLogic().getIdFactory().generateId(); copiedCard.setOwner(owningPlayer); <p> // Add to an appropriate zone. For example, to add the card to the end of the owning player's deck... context.getPlayer(owningPlayer).getDeck().add(copiedCard);

      Specified by:
      getCopy in class Entity
      Returns:
      A copy of the card with no ID or owner (and therefore no location).

      Returns:
      The value of the Attribute.DESCRIPTION on this Card, if it is not null. Otherwise, the CardDesc.getDescription() field.

      Returns:
      An Spellsource.EntityTypeMessage.EntityType

      Returns:
