Defense of the Heart

[jpb]

I recently completed a set of Urza's Legacy, and to celebrate here is the code for Defense of the Heart. Currently creatures you select do not have their come into play effects honored. This is because of a limitation in MTG Forge which would require quite a bit of work to get right.

Add this before Black Vise's entry in GameActionUtil.java's executeUpkeepEffects()

Code: Select all

upkeep_Defense_of_the_Heart();

Add this after GameActionUril.java's executeUpkeepEffects()

    //check if opponent has 3 or more creatures in play

    CardList opponentList = new CardList(opponentZone.getCards());

       //they do not have 3 or more creatures in play, so Defense of the Heart would not be able to be sacrificed.
       return;

At the beginning of your upkeep, if an opponent controls three or more creatures, sacrifice Defense of the Heart to search your library for up to two creature cards and put those creatures into play. Then shuffle your library.


I did not test this well at all. I also didn't add AI since I haven't looked into adding AI for cards not in CardFactory.java. AI wouldn't be too hard for this card. Just need to have the AI select the 2 highest costing creatures in it's library. Other than that it is the same code as what is there.

This card is very situational and it seems like the AI would be hard put to make GOOD use of it. Finding the highest casting cost creatures doesnt necessarily sound like good plays...as I said its highly situational. But good work on coding this. Now to get all your codes into a compiled version for the rest of us to use

[jpb]

The AI of MTG Forge is not the best. Everyone admits that. In most of the cases dealing with creatures it values them based on their cost or power and if it has flying. This is the most bang for the buck in terms of programming. It take about 1 minute to code something to determine the best creature based on cost, power, and flying. It would take a whole new AI approach or many hours of programming to determine the best creature for the situation.

I am not going to compile or distribute MTG Forge. Things will get messy if the code forks. I will leave that up to forge himself to put the code in and release a version. He has been pretty good at getting my changes in quickly.

Great job, looks like a fun card to play! I'll test it out myself.

I looked through your code as well, I think there might be one mistake (easy to fix though), because you have it fizzle whenever you only search for one creature. It says "up to two creatures", so I think you should be able to only fetch one creature and put it into play.

[jpb]

You are right. So this should not fizzle if you select 0 or 1 creatures. I will change the code tomorrow and repost it. Nice catch!
