Collectible Card Game Headquarters

Hi, I'm trying to implement Debt of Loyalty

I thought the best way to implement its effect would be to subclass RegenerateTargetEffect. The regeneration still works in my subclass but the take control part doesn't seem to be functional. Is there something obvious that I'm missing?

Code: Select all

class DebtOfLoyaltyEffect extends RegenerateTargetEffect {
        public DebtOfLoyaltyEffect ( ) {
            super();
            this.staticText = "Regenerate target creature. You gain control of that creature if it regenerates this way.";
        }

        public DebtOfLoyaltyEffect(final DebtOfLoyaltyEffect effect) {
            super(effect);
        }
       
        @Override
        public boolean apply(Game game, Ability source) {
            Permanent permanent = game.getPermanent(targetPointer.getFirst(game, source));
            if (super.apply(game, source) && permanent != null) {
                GainControlTargetEffect effect = new GainControlTargetEffect(Duration.EndOfGame);
                effect.setTargetPointer(targetPointer);
                game.addEffect(effect, source);
                return true;
            }
            return false;
        }
    }

If it helps the rest of the Debt of Loyalty class is here:

More Code | Open

Code: Select all

public DebtOfLoyalty(UUID ownerId) {
        super(ownerId, 127, "Debt of Loyalty", Rarity.RARE, new CardType[]{CardType.INSTANT}, "{1}{W}{W}");
        this.expansionSetCode = "WTH";

        // Regenerate target creature. You gain control of that creature if it regenerates this way.
        this.getSpellAbility().addTarget(new TargetCreaturePermanent());
        this.getSpellAbility().addEffect(new DebtOfLoyaltyEffect());
    }

    public DebtOfLoyalty(final DebtOfLoyalty card) {
        super(card);
    }

    @Override
    public DebtOfLoyalty copy() {
        return new DebtOfLoyalty(this);
    }

Alright, after a lot of debugging and creating a test file I figured out what was wrong. I forgot to override the copy method in DebtOfLoyaltyEffect.

Hopefully my mistake will be helpful to others in the future.
