Also, consider these changes to your apply section (the formating is messed up, but it is readable. I just took your code and "tried" to modify it in the code block:

Code: Select all

@Override
    public boolean apply(Game game, Ability source) {
Player you = game.getPlayer(source.getControllerId());
if (you != null) {
        FilterCard filter = new FilterCard();
        Player damagedPlayer = game.getPlayer(this.getTargetPointer().getFirst(game, source));
        if (damagedPlayer != null) {
            filter.add(new OwnerIdPredicate(damagedPlayer.getId()));
            Target target = new TargetCardInGraveyard(filter);
if (you.chooseTarget(Outcome.Neutral, target, source, game) {
UUID exileId = CardUtil.getCardExileZoneId(game, source);
            game.getPermanent(target.getFirstTarget()).moveToExile(exileId, "Zombie Canibal", source.getSourceId(), game);
return true;
        }
}
}
        return false;

Having an issue with Unstoppable Ash.
The "Predicates.or" within the ChampionAbility class does not seem to work for this, yet it looks okay. The Champion ability will not allow any targets to be chosen. Permanents in play that I control include both the Treefolk and Warrior subtypes, namely Bosk Banneret and Cat Warriors.

You use the wrong signature to create the champion ability.
Instead of
this.addAbility(new ChampionAbility(this, "Treefolk, Warrior"));
use
this.addAbility(new ChampionAbility(this, new String[]{"Treefolk", "Warrior"}));

I fixed a bug and submitted the changes:
SetPowerToughnessAllEffect - Fixed a bug that the effect did not work correctly for static abilities.

Was this your problem (the effect of Godhead didn't work for creatures that entered the battlefield after Godhead)or what exactly did not work?

Your fix worked great. The problem before the fix: When GOA entered the battlefield, the P/T were not changed. Subsequent cards entering the battlefield were not changed either.

[/code]

It does not trigger because the event CAST_SPELL is only used for replacement effects. So only game.replaceEvent() is called and you have to create a replacement effect to react to it.
Chorus of the Conclave's ability isn't a triggered ability.

Chorus of the Conclave creates an additional cost that must be added to the spell ability by a replacement effect.

Ahh. I noticed Molten Disaster which uses the same event check within a TriggeredAbility and thought it would work.

You selected a bad template in this case.
I guess Molten Disaster add split second ability won't work as intended.
I add it to my list of cards that have to be fixed.

Hello everyone,

I am completely new to Java and probably should have started with a less difficult card implementation, but since this one is one of my favourite commanders I thought maybe give it a shot.

So I tried implementing Scion of the Ur-Dragon, hamstering code examples from Entomb and Sarkhan's Triumph. The one thing I cannot get working right away is the correct ability implementation, so it copies the searched card once it's been put into the graveyard.

Since I (still) cannot post my code because it would make my post look "too spamy for a new user" (thanks, forum engine) here's the pastebin link: pastebin[dot]com/xEQTg2EE

Could someone fix it or tell me how to fix it please?

Maybe you're right.

You can look at the code of Dimir Doppelganger or Lazav, Dimir Mastermind that should be good examples. Easy to find if you use the Card Tracker where you can filter e.g. only implemented cards (use % as wildcard for rule search).
But copy effects are always a bit hard and for sure there are still some quirks or better said some details in existings codes that don't work correctly in such effects.

You can starting with post number 5. So it shouldn't be a problem now. I also added your code to your post.

And use the Perl script gen-card.pl to generate the card frame, it's helpful believe me.
E.g. you can remove the color setting from your code it's done automatically now.

If you have more questions don't hesitate to post.

Sorry for the newbie question, but once I have finished the coding of a card how do I get it to show up in the deck editor/game for testing? Card is Rootwater Diver Creature - Merfolk with Tap, sac: return target artifact from your graveyard to your hand. Code is

Package and imports removed do to spam protection on the forum. File name is a java file named Rootwater Diver inside mage-sets-tempest under Mage Sets->Source Packages. I Committed the file, cleaned Mage root, Mage Client, and Mage Server before doing a Build with Dependencies and running the server and client. Not sure what I'm missing. Thank you.

1) Use always the perl script gen-card.pl to create the java class frame. It's much easier than doing it by manually and helps to prevent some simple mistakes. See here to get some info about how to instrall and use it: https://github.com/magefree/mage/wiki/Developer-Getting-Started#perl

2) You don't you see your newly implemented card because the card is not added to the client H2 db. The deck editor works with the H2 client db to show the included cards.
After adding new cards in the IDE you have to check the "force database update" check box in the connect dialog window of the clinet to get the client db updated. Alternatively you can delete all files in the db folder of the client before connecting leading also to a db copy of the server db.
As the xmage server program is started, all missing card entries for the card db are generated from the card classes. For all already existing card records nothing happens this way.
That means if you change the implementation of a card that has influence of the db record, you have to delete the db files of the server before starting the xmage server, so the changes to the card class will be reflected to the db file of the server.
