Collectible Card Game Headquarters

This is by far my most involved keyword development ever. It is also the most modular keyword - it has to support a wide variety of slight differences in the "Draw n cards" mechanic.

syntax:
spDrawCards[Tgt]:num:drawback

where num is:
a number.. like 1, 2, 3
Domain
NumCardsType/type/zone
where type is any single card type (artifact, creature, elf)
where zone is:
YouCtrl, InPlay, InYourYard or InAllYards

where drawback is:
Discard/{num | X}[/[AtRandom | UnlessDiscardType/type]]
LoseLife/{num | X}
NumToLibrary/{num | X}/{Top | Bottom | TopOrBottom}
NumOppDraw/{num | X}
where X really means "X" and will take on the number of cards calculated.

If you include "Tgt" to form "spDrawCardsTgt:" then it will request player targeting prior to resolution.

These are all the draw spells already included:

It's important to note that I wrote an AI for discarding cards that can be applied throughout, where the AI currently discards randomly. The Hand to Library code uses the same logic for now.... I think there should be a difference in logic, but I just wanted to get this done, and it seemed as good as any.

The hand to library "TopOrBottom" function puts BOTH cards either on the top or the bottom. The usual wording of the general mechanic allows the top or bottom decision for each card. But the version of it that's used on a draw spell does specify BOTH. So until the basic code is hacked for the other form, to be used in other spells (scry anyone?) just be aware that it asks once for top or bottom, and then the second (or third, or last) card you select will be the very top card, followed by the prior cards.

The spells are playable by the AI. It will only play them to refill the hand as long as after the discard drawback, its hand will be less than 7. So if it has 5 cards, it won't play Ancestral Recall, but it would play Brainstorm or Sift, when it's added.

Also, I chose 8 as the cut-off for losing life drawbacks. I don't recall any gain life (self or opponent) "drawbacks" on drawspells, but I could easily add it just in case it does show up at some point, or to help support possible fan-made cards.

For targeted spells, the AI will always choose itself... unless and until milling is a viable strategy. (hint hint add the check in SBE, it's so easy)

I'd rather do those with dedicated life gain spells, since the primary AI on them would be related to gaining life, not drawing cards. BTW, if you specify any negative number other than -1 (used in handling "X") you could effectively make the gain life work as is....
And this keyword doesn't cover permanent abilities.

Wow, as always, great stuff Rob! This one seems to cover a lot... and must've taken a long time to implement.
I'll merge this asap, and release a new version in the next few days.

One problem with merging: you created a function sortCMC in CardListUtil:

Code: Select all

CardListUtil.sortCMC(tHand);

Could you post the changes you made in CardListUtil as well ?

Code: Select all

         Card b = (Card)b1;
         
         int cmcA = CardUtil.getConvertedManaCost(a.getManaCost());
         int cmcB = CardUtil.getConvertedManaCost(b.getManaCost());

I didn't analyze the computer's AI on discard, so I wasn't positive that this sort worked in the correct order (lowest to highest).

Great work Rob, hopefully you didn't pull out any hair.

No.. no hair loss that I'm aware of. But I did lose a little sleep.

Funny enough, while I complain about my wife's facebook habits in marriage counseling, she's equally complained of my coding habits for MTGForge. While she has virtual farms and virtual mafias to her credit, I've gotten hundreds of cards added to the game.

I have been fairly busy in recent days. I'm sure that Dennis would like to release the next version in the near future. Rob has done a wonderful job with this keyword, and I have to agree that the syntax is complicated.

I did a search on the word "Draw" and was surprised to see so many hits. I grabbed eight cards that can be implemented for the next version. These cards are fairly simple in syntax. There are still many candidates that are not yet implemented/submitted. Some of these will require a more complicated form of the syntax.

The cards that I am submitting are:

@ Dennis:

I will pm the card data and the jpg urls to you.

Those look good. Yeah, there are a lot of hits if you're just searching for "Draw"....

When I was doing the research for the different forms, I found it best to filter the phrase "Draw a card", since it's a tack-on effect, and present in "cycling", another tack-on. I didn't think of it at the time, but also filter "whenever" or "next", as there were some spells that created triggers. Also limit the search to just instants and sorceries.

If you come across any additional variations that seem simple, logical or popular enough, then let me know and I'll add it.

Once I filtered out the cantrip and cycling cards the list became a wee bit easier to handle. There was still a third type which states:

Draw a card at the beginning of the next turn's upkeep.

This one looks like it should be a separate keyword and might be somewhat similar to the cantrips.

Yeah.. those were the ones I was talking about... I'm not about to try to figure out a delayed trigger of that magnitude....

Don't get me started on therapists.

I think that I have figured out how to add an additional 15 cards. Many of these 15 cards require a fairly complicated form of the syntax, but I think that I have the following cards figured out.

I may have missed a number of cards that can be included, if anyone else figures out a few more of these cards, that would be great.

My fiancee just got started on Facebook, and she has a farm now too. It's quite pointless IMO but so are my games I suppose. I think her time is better spent cooking me food and rubbing my feet.
