1.34 will support using Groovy to write card scripts

[melvin]

Have you thought about using something like Groovy as a dynamic scripting language, so new cards with new card-logic could be added on the fly?

Yes! Unfortunately I'm not familiar enough with Groovy to check if it can be used to create classes like those we use for card code. I suspect it can, but then I couldn't figure out how to have groovy load a script and get back a class. I'd appreciate any advice on this topic.

As part of work, I looked at Groovy again. One of our projects is using Gradle, the build system written in Groovy. I did some quick searches and came across http://groovy.codehaus.org/Embedding+Groovy The latest version of the Groovy language supports most of Java, so I did a quick integration. Imagine my surprise when I took one of the card code, rename it to .groovy and it worked without any modifications. I took the opportunity to simplify the Groovy version a little so it was easier to integrate and write.

Below is the card I tested with. Note that change in the last property from requires_card_code to requires_groovy_code. A preview of 1.34 with groovy scripting is available via our hourly build @ https://buildhive.cloudbees.com/job/mel ... a-1.34.zip

Thanks to smoof for reminding me about Groovy. Look forward to your comments/suggestions for this feature.

As comparison, here is the original card code, src/magic/card/Lord_of_Extinction.java

Code: Select all

package magic.card;

import magic.model.MagicGame;

public class Lord_of_Extinction {
    public static final MagicCDA CDA = new MagicCDA() {
        @Override
        public void modPowerToughness(final MagicGame game,final MagicPlayer player,final MagicPowerToughness pt) {
            final int amount=game.getPlayer(0).getGraveyard().size()+game.getPlayer(1).getGraveyard().size();
            pt.set(amount,amount);
        }
    };

I picked up a Groovy book at the used bookstore and it looks awesome. Groovy is like Java minus the icky syntax and boilerplate code.
