Hello all. I'm new to Decker. I'm building a deck that has differently themed groups of cards. I'd like to intercept field hyperlink clicks such that clicking a link from one card to another card within the same group navigates as normal, while clicking a link to a card in a different group plays a transition. How can I achieve this? Thanks!

Since you're overriding this behavior on many cards, it's easiest to define an overload for the link[] event at the deck level; see Deck -> Properies... -> Script... via the menu. I'll assume for the sake of this example that cards are named with a "group_cardname" convention, so we can use the portion of the name preceding the underscore to determine whether two cards belong to the same group:

on link x do
 on groupname x do
  first "_" split x
 end
 if groupname[deck.card.name]~groupname[x]
  send link[x]
 else
  go[x "BoxIn"]
 end
end

Make sense?

You may have a different method of distinguishing groups, like invisible metadata fields on cards; I'd be happy to clarify how to adapt this approach to your deck, if needed.

Thank you. That was very helpful. Here's what I ended up using:

on link x do
target: deck.cards[x]

  if target
  if !(target.widgets.channel.text = card.widgets.channel.text)
  go[x "Wink"]
  else
  go[x]
  end
  else
  send link[x]
  end
end

What about go["Back"]? I want to keep the simplicity of go["Back"], but need to ensure that my transition plays when going back to a different card group. Thanks again!

Hmm. Tricky.

How about something like this?

on link x do
 here:deck.card
 send link[x]
 there:deck.card
 if !(here.widgets.channel.text=there.widgets.channel.text)
  go[here]
  go["Back" "Wink"]
 end
end

Sorry for the confusion. I have links and buttons in the mix. Your answer solved the link issue. However, I also have buttons with the Back action. I need to make sure that if a back button from a channel one card would go back to channel two card, it plays the transition.

In that case you might want to consider giving the buttons a script that delegates to your link[] logic:

on click do
 link["Back"]
end
