etbDestroyTgt keyword

by **Rob Cashwalker** » 04 Sep 2010, 15:15

Cards that destroy target ____ when they enter the battlefield. It supports a "May" clause, "NoRegen", "Evoke" and drawbacks.

Follows the basic syntax of the spDestroyTgt keyword:
etbDestroyTgt{May}:{ValidCards}:{NoRegen and/or Drawback}

Use SVar:Evoke:{cost} to enable Evoke.

CardFactory:

Code: Select all: // Generic enters the battlefield destroy target if (hasKeyword(card, "etbDestroyTgt") != -1) { int n = hasKeyword(card, "etbDestroyTgt"); String parse = card.getKeyword().get(n).toString(); card.removeIntrinsicKeyword(parse); String k[] = parse.split(":"); final boolean May[] = {false}; if (k[0].contains("May")) May[0] = true; String Targets = k[1]; final String Tgts[] = Targets.split(","); String tmpDesc = card.getSpellText(); int i = tmpDesc.indexOf("destroy target "); tmpDesc = tmpDesc.substring(i + 15); i = tmpDesc.indexOf("."); tmpDesc = tmpDesc.substring(0, i); final String Selec = "Select target " + tmpDesc + " to destroy."; final boolean NoRegen[] = {false}; final String Drawback[] = {"none"}; if (k.length > 2) { if (k[2].equals("NoRegen")) { NoRegen[0] = true; if (k.length > 3) Drawback[0] = k[3]; } else Drawback[0] = k[2]; } if (!Drawback[0].equals("none")) { String kk[] = Drawback[0].split("\\$"); Drawback[0] = kk[1]; } final boolean Evoke[] = {false}; if (card.getSVar("Evoke").length() > 0) Evoke[0] = true; card.setSVar("PlayMain1", "TRUE"); card.clearSpellAbility(); // over-rides the default Spell_Permanent // enables the AI to play the card when appropriate SpellAbility spETBDestroyTgt = new Spell_Permanent(card) { private static final long serialVersionUID = -1148528222969323318L; @Override public boolean canPlayAI() { Random r = new Random(); CardList hCards = new CardList(AllZone.getZone(Constant.Zone.Play, Constant.Player.Human).getCards()); hCards = hCards.getValidCards(Tgts); if (hCards.size() > 0) return true; CardList cCards = new CardList(AllZone.getZone(Constant.Zone.Play, Constant.Player.Computer).getCards()); cCards = cCards.getValidCards(Tgts); if (cCards.size() == 0) return true; else { if (r.nextInt(100) > 67) return true; } return false; } }; card.addSpellAbility(spETBDestroyTgt); // performs the destruction final SpellAbility saDestroyTgt = new Ability(card, "0") { @Override public void resolve() { Card c = getTargetCard(); if (c == null) return; if(AllZone.GameAction.isCardInPlay(c) && CardFactoryUtil.canTarget(card, c)) { if(c.isToken()) AllZone.getZone(c).remove(c); else AllZone.GameAction.destroy(c); if (!Drawback[0].equals("none")) CardFactoryUtil.doDrawBack(Drawback[0], 0, card.getController(), AllZone.GameAction.getOpponent(card.getController()), c.getController(), card, c); } } }; saDestroyTgt.setStackDescription(card.getName() + " - destroy target " + Selec + "."); // when the card enters the battlefield, enable the human to target // or the AI decides on a target Command etbDestroyTgt = new Command() { private static final long serialVersionUID = 9072052875006010497L; public void execute() { CardList hCards = new CardList(AllZone.Human_Play.getCards()); CardList cCards = new CardList(AllZone.Computer_Play.getCards()); hCards = hCards.getValidCards(Tgts); cCards = cCards.getValidCards(Tgts); if(hCards.size() > 0 || cCards.size() > 0) { if (card.getController().equals(Constant.Player.Human)) { Input inDT = CardFactoryUtil.input_targetValid(saDestroyTgt, Tgts, Selec); AllZone.InputControl.setInput(inDT); if (May[0] == true) ButtonUtil.enableOnlyCancel(); else ButtonUtil.disableAll(); } else { Card c = new Card(); CardList dChoices = new CardList(); if(hCards.size() > 0) { for (int i=0; i<Tgts.length; i++) { if (Tgts[i].startsWith("Creature")) { c = CardFactoryUtil.AI_getBestCreature(hCards); if (c != null) dChoices.add(c); } CardListUtil.sortByTextLen(hCards); dChoices.add(hCards.get(0)); CardListUtil.sortCMC(hCards); dChoices.add(hCards.get(0)); } c = dChoices.get(CardUtil.getRandomIndex(dChoices)); saDestroyTgt.setTargetCard(c); AllZone.Stack.add(saDestroyTgt); } else if (cCards.size() > 0 && May[0] == false) { for (int i=0; i<Tgts.length; i++) { if (Tgts[i].startsWith("Creature")) { c = CardFactoryUtil.AI_getWorstCreature(cCards); if (c != null) dChoices.add(c); } CardListUtil.sortByTextLen(cCards); dChoices.add(cCards.get(cCards.size() - 1)); CardListUtil.sortCMC(cCards); dChoices.add(cCards.get(cCards.size() - 1)); } c = dChoices.get(CardUtil.getRandomIndex(dChoices)); saDestroyTgt.setTargetCard(c); AllZone.Stack.add(saDestroyTgt); } } } } }; card.addComesIntoPlayCommand(etbDestroyTgt); // handle SVar:Evoke:{cost} if (Evoke[0] == true) { String EvCost = card.getSVar("Evoke"); SpellAbility evDestroyTgt = new Spell_Evoke(card, EvCost) { private static final long serialVersionUID = 5261598836419831953L; @Override public boolean canPlayAI() { return false; } }; card.addSpellAbility(evDestroyTgt); } } // etbDestoryTgt

Nice keyword, Rob!

Most of the cards were possible with the whenever keyword, but the targeting for the AI caused an error when using destroy.

I agree with adding simple keywords to replace some of the wheneverkeyword's functionalities. It will make the AI more easily improveable.

I'm not up to date with isValidCard, but shouldn't
etbDestroyTgt:Creature.nonArtifact.nonBlack
be
etbDestroyTgt:Creature.nonArtifact+nonBlack
?

used in:

Code: Select all: Bone Shredder 2 B Creature Minion When Bone Shredder enters the battlefield, destroy target nonartifact, nonblack creature. 1/1 Flying Echo:2B etbDestroyTgt:Creature.nonArtifact.nonBlack

and Nekrataal

Hope you had a good vacation, Sloth.

Here is the cards.txt entry for Terror:

It certainly is....

Figures.. I recently put together the reference topic, and didn't even notice that.

Would a "etbDestroyAll" keyword be a waste of time with all the changes taking place? I would like to add Desolation Angel and Desolation Giant.

Yep. Once triggers are in place we should be able to do that.
