Open source rules engine for Magic: The Gathering

• forge

  32 806 10.0 Java

  An unofficial rules engine for the world's greatest card game. (by Card-Forge)

  

In case anyone is curious, it uses Scryfall for the card art https://github.com/Card-Forge/forge/blob/forge-1.6.59/forge-... and I wish they'd offer a torrent (or IPFS) because I can't imagine the amount of bandwidth it must cost them and I would seed the hell out of any such thing

Now, one possible reason would be copyright something-something but as it currently stands it's not like one needs to log in to download the card art one at a time, so ... I struggle to think of what risk they're driving down

  Drools is a rule engine, DMN engine and complex event processing (CEP) engine for Java.

  

That's interesting, thank you. It seems what's old is new again: I had a lot of contact with CLIPS early in my career but I found that most of the programming tasks weren't heavy rules based as much as CRUD and reporting apps. Given that Forge is in Java, they may enjoy Drools <https://github.com/apache/incubator-kie-drools#readme> (which used to be a JBoss project but I guess has been donated to the Apache Foundation)

• muzero-general

  MuZero

I went looking for MuZero implementations in order to see how, exactly, they interact with the game space. Based on this one, which had the most stars in the muzero topic, it appears that it needs to be able to discern legal next steps from the current game state https://github.com/werner-duvaud/muzero-general/blob/master/...

So, I guess for the cards Forge has implemented one could MuZero it, but I believe it's a bit chicken and egg with a "free text" game like M:TG -- in order to train one would need to know legal steps for any random game state, but in order to have legal steps one would need to be able to read and interpret English rules and card text

I find the CardScript repository very interesting to look at: https://github.com/ProjectIgnis/CardScripts

  Magic: The Gathering, but in Ruby (by radar)

I’ve done some work on something “less serious” in Ruby:

https://github.com/radar/mtg

I view it as a wide project full of little interlinked code katas.

I’ve thought about the card parsing stuff but that’s beyond my ability.
