Collectible Card Game Headquarters

Finally assembled this keyword.. I had begun working on it a couple months ago.

Right now it only handles basic discards, where the targeted player or opponent chooses. The reveal and choose type are next, and will be part of the same keyword.

Syntax:

Code: Select all

spDiscard[Tgt|Opp]:[TgtChoose|OppChoose|AtRandom|Hand]:<numCards>:<Drawback:Spell Description:StackDescription>


When using "Hand" as the discard method, the number of cards may be 0 or any number... because it's ignored.

Code: Select all

        {
           int n = hasKeyword(card, "spDiscard");

Surging Dementia was the only one already implemented. Someone got clever with the spDamage keyword, using it with 0 damage and a Drawback of Discard.

You're version of Forget seems to allow a player to draw two cards if it is the last card in his hand. This should not be possible with the oracle wording.

Syphon Mind has the same problem.

good catch. Forget about Forget.

I merged my local copy up to r1390 and noticed a warning in CardFactory.java. The local variable Opp is never read. This is line 468.

Code: Select all

        if (hasKeyword(card, "spDiscard") != -1)
        {
           int n = hasKeyword(card, "spDiscard");
           
           String parse = card.getKeyword().get(n).toString();
           card.removeIntrinsicKeyword(parse);
           
           String k[] = parse.split(":");
           final boolean Tgt = k[0].contains("Tgt");
           final boolean Opp = k[0].contains("Opp");

`
Some of the cards you list use the Opp rather than the Tgt in k[0] … so I wild hold off on adding new cards or converting over the existing cards for the moment.

No, go ahead with it. The "Opp" flag may become useful for the next stage.

Could this keyword also work for "(You) Discard a card" as a cost? With Self as an option for the target. This could work great for spellshapers.

It may be easier for parsing to have the keyword just be spDiscard and let the first parameter be who is discarding.

Ex.
spDiscard:[Tgt|Opp|(Self)]:[TgtChoose|OppChoose|AtRandom|Hand]:<numCards>:<Drawback:Spell Description:StackDescription>

As for the second parameter, what is the difference betwen TgtChoose and OppChoose? It seems they might be "Discarding player chooses" and "Opponent of discarding player chooses". Maybe they can be clarified to OwnerChoose and OpponentChoose?

Although, I feel like that still may be confusing since the Opponent in the first parameter is different than the Opponent in the second parameter. Unless I'm confused myself.

No, discarding as a cost should be done as a cost. The AI for this assumes the intention is to make the player discard. Discarding as a cost should have AI that doesn't so much care about the discarding, more about the ultimate effect.
Same goes for how using "spDamageTgtP:0:Drawback$TgtDiscard:1" achieves the mechanical effect of "target player discards a card". However the AI for it assumes it's trying to deal damage to the player, so it would likely play the spell (if the AI calculation using zero damage even gets that far) even when the player had no cards in hand.

Tgt goes with TgtChoose and Opp goes with OppChoose. They're distinct effects - you could choose yourself if it's "target player" but not if it's "target opponent". However, we could probably drop the OppChoose, because the target player is set specifically to the opponent if not Tgt.

Rob Cashwalker wrote:No, go ahead with it. The "Opp" flag may become useful for the next stage.

OK, no prob. I will add the cards and pic urls. Several cards will need to be converted. While I am at it I will put in a suppress warning.

Ok, so this currently wouldn't handle a card like Coercion, because the Caster is the one who chooses (and not the target)?

Right... RevealYouChoose will be the next method implemented.

The cards.txt entries that use the spDiscardOpp form of the keyword are causing a null error.

Hmm...

When the card's being created it has no controller... duh.

fixed it in r.1393

Plus, I make use of Opp, so no more warning.

Thank you Rob.

I will merge in the new code and will then run a test to see if I am still having trouble adding Mind Peel. Mind Peel gave me an error in reference to the mana cost of the SVar Buyback:

I converted the 5 existing cards from code based to keyword-ed and they have been merged. All but 2 of the new cards have also been merged. So, all of the cards listed have been taken care of except for:

Forget
Mind Peel

I fixed the addManaCosts method to correctly handle adding a mana cost with no numeric component. Mind Peel costs B, so Integer.valueOf("") apparantly is the number format exception.... In VB Val("") is 0.
