public class ModifyMaxManaSpell
extends Spell

Adds or destroys SpellArg.VALUE mana crystals. Gives the player full mana crystals when SpellArg.FULL_MANA_CRYSTALS is true.

This example shows the text "Transform your Mana Crystals into 2/2 minions. Recover the mana when they die." Observe that a GameValueProvider is used to only destroy as many mana crystals as the player has empty minion spots, but before the minions themselves are summoned. This ensures everything occurs in the right order.

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.

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

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.
