Collectible Card Game Headquarters

I just added a new random deck generator. It allows the user to specify the colors.

At the moment it doesn't handle dual lands, nor does it add any artifacts.

It attempts to promote a slight mana curve, and most cards should not be singleton.

A better random deck generator sounds great. Sometimes the current deck generator (which I wrote) is too random since it doesn't consider a mana curve at all. (I think the old deck generator did create decks with at least 12 creatures.)

Thanks of the update because I enjoy using and playing against generated decks. (I turn on the AI Land Stack option in order to make it more challenging.)

Made some changes this weekend.

First off, I added support for dual lands in the 2-color generator.

Then I changed how both the them deck generator and the 2-color generator count mana colors for the ratio of lands. It now counts each mana symbol.

I also changed the NewGame screen. Instead of listing all the different deck generators, I left only one "Generate Deck". It then presents a list dialog with the different generators.

Finally, I added a property to enable/disable the display of the 2-color deck list. "showdeck/2color=true"

For Hybrid Mana do those count as half mana or full mana?

Alas, I still haven't decided how those should count. For now, they count full.

Rob Cashwalker wrote:Alas, I still haven't decided how those should count. For now, they count full.

How about this?
2/R counts as a full.
R/G in a red/green deck count as a half each.
R/G in a red/black deck counts as a full.

R/G in a R-B THEME deck, I guess... but how to know that the deck is supposed to be R-B, when there's G in a mana cost..?
R/G in a R-B GENERATED deck, will never occur, because of the color-selection filter - it removes any card that has a mana symbol outside of the decks two chosen colors.

In the long run I don't think it makes a huge difference:

given the mana costs for a simple R/G deck:
R
1 R
R R
2 R
G
1 G
G G
2 G
R/G
1 R/G
R/G R/G
2 R/G

colors always count as full: 10R + 10G = 20total (50%R 50%G)
hybrids count as half: 7.5R + 7.5G = 15total (50%R 50%G)

Since the 1002 release I find myself, when not questing, playing allot of the 2 colour generated deck mode. I really like it & it seems very well balanced.

Just saw that dual lands are now included. Is there a way to eventually get a smattering of Artifacts in the mix too? Maybe colour specific Arty's like Scepter of Fugue when playing Black as one of your colours as an example. Would Arty's with a specific mana colour cost make it easier for them to be included and for randomization of those picks as well?

In any event, I really like the balance I've seen with this so far Rob, thanks very much for all the work!

I think if artifacts came into the mix, then it would end up diluting the colored cards.... This generator tries to promote card multiples.
I was also trying to think of an easy way to eliminate on-color cards with off-color activations, and I couldn't think of a simple, universal way, since not all abilities provide the activation cost, and not all cards include them in the card text.... Plus, how to differentiate "W" as a mana cost and not as a character in the word "Whenever".
Definitely something to look at at some point.

I played a number of matches with both players using these 2 color decks, and the computer was doing a kick-ass job, much better win % than the original generator.

I'm going to add a color option to the color list - "Random".

I get what you mean about artifacts & it's no big deal not to have them.

I too have noticed that the AI is performing at a higher level then before. I find the games closer and the AI making more logical choices with the cards in hand vs what is already played to the table. I also find that the deck compositions are well balanced and that the randomization of the cards in the decks in multiple replays are very fair and playable.

As I said earlier, I find myself playing this more & more & enjoying it immensely!

Rob Cashwalker wrote:I was also trying to think of an easy way to eliminate on-color cards with off-color activations, and I couldn't think of a simple, universal way, since not all abilities provide the activation cost

Uh, they don't? Since when is getManaCost() depreciated?

Heh... you know, I was so busy working at this from the card level, I didn't really think about the SpellAbility.getManaCost(). On the other hand, some abilities (and most future ones) use the Ability_Cost, maybe the mana portion is copied to the SpellAbility?

Ability_Cost sets the ManaCost during creation of an ability.

Code: Select all

    public Ability_Activated(Card sourceCard, Ability_Cost abCost, Target tgt) {
        super(SpellAbility.Ability, sourceCard);
        setManaCost(abCost.getMana());
        setPayCosts(abCost);
        if (tgt != null && tgt.doesTarget())
           setTarget(tgt);
    }


Even if it didn't we could have getManaCost() check if abCost was set, and return the ManaCost from there instead of the unintiated ManaCost.

I am getting an exception generating a 5 color deck:

I pick a constructed deck for human and generate Deck for AI, then choose 5-color -> OK -> exception.

-slapshot5

I'm getting that too, on my work pc that hasn't been updated in a couple weeks, since before my updates. I didn't make any changes to the 5 color generator.

I'm suspecting it might be due to the changes involving card color.
