I think it always return false, maybe you should return true somewhere after the case.

I thought the same, but that simply results in a null event...
I tested other cards using the same event.setAmount and they all work. It may be that life gain is not using it.

I fixed both GAIN_LIFE and LOSE_LIFE events, now updated amount should be taken into account.

Also in replacement effects that _updates_ the event you should always return false. True should be returned only when one event is replaced by another or removed totally: usually it is used for effects saying that you do something different instead (e.g. "if a player would gain life, it loses that much life instead" or "players can't gain life").

Working on Spelltwine. The following code does not exile any of the cards. Does anyone see the issue?

Hi,

First of all, the card you cast can't be exiled inside effect because it will go to graveyard on resolution anyway. What you need in such cases is PostResolveEffect to be implemented that will exile it instead.
And for "exile {this}" effects there is PostResolveEffect already created so all you need is just to add:

Code: Select all

this.getSpellAbility().addEffect(ExileSpellEffect.getInstance());

Take a look at Temporal Mastery as an example.

Next is about the cards you target in graveyard, exile and copy.
Whenever you call card.copy() you create exact copy of the card. You don't create a clone copy, but just make another reference to it. So your code exiles the same card, but then you cast it that again according to rules puts it to the graveyard so that's why it looks like the exile effect doesn't work: but it works, the game just puts the same card back to graveyard.

What should be done in such cases is giving new id to the copied card and adding it to the game so it could track it:

Code: Select all

if (cardTwo != null) {
                cardTwo.moveToExile(null, "Exiled card from opponent's graveyard", source.getId(), game);
                Card copyTwo = cardTwo.copy();
                copyTwo.assignNewId();
                copyTwo.setControllerId(source.getControllerId());
                Set<Card> cards = new HashSet<Card>();
                cards.add(copyTwo);
                game.loadCards(cards, source.getControllerId());
                you.cast(copyTwo.getSpellAbility(), game, true);
            }

I'll add method to the Game interface for copying card, so it will be shorter and look like:

Code: Select all

Card copyTwo = game.copyCard(cardTwo, source, newController);

Best Regards,
Noxx

Working on Kederekt Parasite. The following code does not treat the ability as optional. Does anyone see the issue?

Do you still need a help with the card or was it finally implemented?

BR,
Noxx

I moved on. It never did work. On a side note, alternative costs text does not display. Example: Firewild Borderpost

Didn't know about Firewild Borderpost alternative cost not displayed.

Finally commited a failing test for it and made fix for rule text displayed that ignored alternative costs.

I made an attempt at Ali Baba and I'm iffy on these lines.

Code: Select all

private static final FilterCreaturePermanent filter = new FilterCreaturePermanent("Wall");
   

    static {
        filter.add(new SubtypePredicate("Wall"));
     
    }

Ability ability = new SimpleActivatedAbility(Constants.Zone.BATTLEFIELD, new TapTargetEffect(), new ColoredManaCost(Constants.ColoredManaSymbol.R));
        ability.addTarget(new TargetCreaturePermanent(filter));
        this.addAbility(ability);
    }

The rest of it is basically Mons's Goblin Raiders save for the imports.

I have no experience with Java only MATLAB but am I on the right track so far?

Hi,
I created some new cards. Can you add it to the main projet. If you want, I can create more cards.

Thank you Plopman. I'll look over them and commit them to the project.

As for the second part, please do create more cards.

I create 10 new cards
