public final class AddDeathrattleSecondaryAsTargetSpell
extends AddDeathrattleSpell

Gives the target the SpellArg.SPELL as a deathrattle.

Resolves the SpellArg.SECONDARY_TARGET and puts it as the SpellArg.TARGET of the SpellArg.SPELL (the deathrattle).

This is useful for "saving" the player's choices or a state of the board. For example, to implement a battlecry, "Battlecry: Choose a minion. Deathrattle: Destroy it.":

   "battlecry" {
     "targetSelection": "MINIONS",
     "spell": {
       "class": "AddDeathrattleSecondaryAsTargetSpell",
       "secondaryTarget": "TARGET",
       "target": "SELF",
       "spell": {
         "class": "DestroySpell"
       }
     }
   },
   "deathrattle": {
     "class": "NullSpell"
   },
   "attributes": {
     "BATTLECRY": true,
     "DEATHRATTLES": true
   }
 

Observe that the "secondaryTarget" is EntityReference.TARGET, which is the player's chosen target (the minion). This effect then resolves EntityReference.TARGET and puts it into the DestroySpell's SpellArg.TARGET. Observe also that the minion's "deathrattle" is a NullSpell; if other effects try to cast its deathrattle from the deck, for example, it will correctly do nothing.

Method Details

onCast

protected void onCast(GameContext context,
 Player player,
 SpellDesc desc,
 Entity source,
 Entity target)

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.

Overrides:

onCast in class AddDeathrattleSpell

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

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

target - 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.
