Works for me here. (The card loading, unable to test the card currently) Try copy pasting from your post into the card file, there may have been an extra line somewhere that mucks things up.

It works, I copy the post and test this card (River Kelpie) on forge. It functions well (with persist, flashback, etc...).The only problem I found is when a play lands from my graveyard (with Crucible of Worlds), the first trigger ability of the River Kelpie don't work.
Why? The first trigger ability of the River Kelpie would must works how it is scripted.

I've tried the search function, but it appears that it's not working or what I'm looking for is not here. So, I'll just ask...
Is there any document explaining how to script cards?

Start here: http://www.slightlymagic.net/wiki/Forge_API

It's not 100% up-to-date but it's a good start. Also, reading existing card scripts can give you an idea of how it works.

Find a card you like. Search for a similar card that is already scripted. Bear in mind that pretty much all the "easy" cards are done.

I see in forge not exists cards like Comet Storm, Conflagrate, Rock Slide, Magmatic Core, Meteor Shower, etc...
Cards that deals X damage divided as you choose among any number of target creatures (and/or players)

Exists any impediments to script then?

Thanks

Check out the java-coded Fireball. No way to script these just yet.

Fireball is actually a different scenario since the number is divided evenly. (I think Fireball might be actually scriptable)

The cards Iran is talking about are "Divide as you choose." We do have a few cards that "fake" this like Pyrotechnics, but this only works for a known amount of damage. It'd be nice to have a "Divided" parameter for Damage and for any other AF that uses it. (PutCounter I think, maybe Pump)

I agree with you, several cards I see use "Divide as you choose" and not known amount of damage that cards causes.

Anyone knows if the parameter RememberDiscarded was placed in AF_Discard?

thanks

Exists in forge any keyword or AF that have the effect below?

Target creature blocks CARDNAME this turn if able.

I would like to script Sisters of Stone Death. With her i can do a Gorgon Deck with Gaze of the Gorgon, Gorgon Recluse, Infernal Medusa, etc...

Other card that can use the effect above is Matsu-Tribe Decoy

Thanks

Well, the AF that Gideon Jura uses is meant for this.

Nope, check that. That was for attacks. I'd need to write another AF for blocks in a similar fashion. I'll do that sometime this weekend, but the Brewers are on right now, so it won't be now!

For the AB$ Destroy, Defined$ Targeted doesn't work. Do I need some kind of Triggered variable here?

If you use Defined$ TriggeredSource, Will this works?

[slapshot5]

No, it doesn't. I'm not even sure a triggered variable works here. I don't think that all gets set up in a DelayedTrigger.

I believe Defined$ Targeted is what is desired, but is possibly not preserved (or can't be traced back through) the DelayedTrigger.

It would be nice if "remembered" was extended to all the AB's.
