Class OverrideTargetSpell
java.lang.Object
net.demilich.metastone.game.spells.Spell
net.demilich.metastone.game.spells.OverrideTargetSpell
- All Implemented Interfaces:
Serializable
,HasDesc<SpellDesc>
Overrides the target of the next
GameLogic.targetAcquisition(Player, Entity, GameAction)
call.
Overrides are always cleared at the end of evaluating a game action (not necessarily at the end of a sequence).
Use in combination with a TargetAcquisitionTrigger
to override
player-chosen targets. For example, this code will implement the text, "Whenever a Fireball is cast, cast it
instead on the enemy hero."
"trigger": { "eventTrigger": { "class": "TargetAcquisitionTrigger", "actionType": "SPELL", "fireCondition": { "class": "CardPropertyCondition", "target": "EVENT_SOURCE", "card": "spell_fireball" }, "sourcePlayer": "BOTH", "targetPlayer": "BOTH" }, "spell": { "class": "OverrideTargetSpell", "target": "ENEMY_HERO" } }

onCast
protected void onCast(GameContext context, Player player, SpellDesc desc, Entity source, Entity target) Description copied from class:Spell
Implementations ofonCast
are the meat-and-bones of a spell's effects. This should actually call a variety of methods inGameLogic
, generate cards usingSpellUtils.getCards(GameContext, Player, Entity, Entity, SpellDesc)
, interpretSpellArg
keys in thedesc
, etc.Observe that subclasses of
Spell
mostly just need to implement this function. Also, observe that instances ofSpell
are stateless: all the state is provided as arguments to this function.- Specified by:
onCast
in classSpell
- Parameters:
context
- The game contextplayer
- The casting playerdesc
- The collection ofSpellArg
keys and values that are interpreted by the implementation of this function to actually cause effects in a gamesource
- 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.- See Also:
