Direct Known Subclasses:

SwapCardsInHandAndDeckSpell

public class SwapCardsSpell
extends Spell

Swaps the card pointed to by SpellArg.SECONDARY_TARGET with the target Card.

For example, put this text on a card to swap it with one in your deck while the card is in your hand:

     "passiveTrigger": {
          "eventTrigger": {
              "class": "TurnEndTrigger",
              "targetPlayer": "SELF"
          },
          "spell": {
              "class": "SwapCardsSpell",
              "secondaryTarget": "SELF",
              "target": "FRIENDLY_DECK",
              "randomTarget": "true"
          }
      }
 

passiveTrigger indicates a Enchantment that is active while the host entity (in this case, a card) is in the player's hand.

Method Details

onCast

protected void onCast(GameContext context,
 Player player,
 SpellDesc desc,
 Entity spellSource,
 Entity spellTarget)

Description copied from class: Spell

Implementations of onCast are the meat-and-bones of a spell's effects. This should actually call a variety of methods in GameLogic, generate cards using SpellUtils.getCards(GameContext, Player, Entity, Entity, SpellDesc), interpret SpellArg keys in the desc, etc.

Observe that subclasses of Spell mostly just need to implement this function. Also, observe that instances of Spell are stateless: all the state is provided as arguments to this function.

Specified by:

onCast in class Spell

Parameters:

context - The game context

player - The casting player

desc - The collection of SpellArg keys and values that are interpreted by the implementation of this function to actually cause effects in a game

spellSource - The entity from which this effect is happening (typically a card or a minion if it's a battlecry).

spellTarget - The particular target of this invocation of the spell. When a spell hits multiple targets, like an AoE damage effect, this method is called once for each target in the list of targets.

 Card card1,
