Examples with AbilitiesImpl mage.abilities.AbilitiesImpl used on opensource projects

Example 1 with AbilitiesImpl

use of mage.abilities.AbilitiesImpl in project mage by magefree.

the class StackObjectImpl method chooseNewTargets.

/**
 * 114.6. Some effects allow a player to change the target(s) of a spell or
 * ability, and other effects allow a player to choose new targets for a
 * spell or ability.
 * <p>
 * 114.6a If an effect allows a player to "change the target(s)" of a spell
 * or ability, each target can be changed only to another legal target. If a
 * target can't be changed to another legal target, the original target is
 * unchanged, even if the original target is itself illegal by then. If all
 * the targets aren't changed to other legal targets, none of them are
 * changed.
 * <p>
 * 114.6b If an effect allows a player to "change a target" of a spell or
 * ability, the process described in rule 114.6a is followed, except that
 * only one of those targets may be changed (rather than all of them or none
 * of them).
 * <p>
 * 114.6c If an effect allows a player to "change any targets" of a spell or
 * ability, the process described in rule 114.6a is followed, except that
 * any number of those targets may be changed (rather than all of them or
 * none of them).
 * <p>
 * 114.6d If an effect allows a player to "choose new targets" for a spell
 * or ability, the player may leave any number of the targets unchanged,
 * even if those targets would be illegal. If the player chooses to change
 * some or all of the targets, the new targets must be legal and must not
 * cause any unchanged targets to become illegal.
 * <p>
 * 114.6e When changing targets or choosing new targets for a spell or
 * ability, only the final set of targets is evaluated to determine whether
 * the change is legal.
 * <p>
 * Example: Arc Trail is a sorcery that reads "Arc Trail deals 2 damage to
 * any target and 1 damage to another target creature or player." The
 * current targets of Arc Trail are Runeclaw Bear and Llanowar Elves, in
 * that order. You cast Redirect, an instant that reads "You may choose new
 * targets for target spell," targeting Arc Trail. You can change the first
 * target to Llanowar Elves and change the second target to Runeclaw Bear.
 * <p>
 * 114.7. Modal spells and abilities may have different targeting
 * requirements for each mode. An effect that allows a player to change the
 * target(s) of a modal spell or ability, or to choose new targets for a
 * modal spell or ability, doesn't allow that player to change its mode.
 * (See rule 700.2.)
 * <p>
 * 706.10c Some effects copy a spell or ability and state that its
 * controller may choose new targets for the copy. The player may leave any
 * number of the targets unchanged, even if those targets would be illegal.
 * If the player chooses to change some or all of the targets, the new
 * targets must be legal. Once the player has decided what the copy's
 * targets will be, the copy is put onto the stack with those targets.
 *
 * @param game
 * @param targetControllerId       - player that can/has to change the target of
 *                                 the spell

 *                                 targetId
 * @param onlyOneTarget            - 114.6b one target must be changed to another
 *                                 target
 * @param newTargetFilterPredicate restriction for the new target (null - can select same targets)
