Using Tarot cards on Roll20?

Who has used tarot cards on Roll20 before? What has been your experience with it?

I've not really used them, but I can tell you one problem you may run into: You'll never get an inverted card.

Would there be a way to connect a simple coin flip action result with each card that is dealt to a player? Heads as Upright and Tails as Reversed.

Yes, with the API it would be trivial, but that would require a Pro Subscription.

If you were to create your own custom deck, you could double the number of cards, and include each one twice, one normal, one inverted.

Or simply have another table set up with "Normal" and "Inverted" as potential results and 'roll' on that after each draw to allow you to rotate the last card pulled or not... might break the flow a little bit though :/

Ziechael's suggestion sounds better to me, because each draw - whether normal or inverted - removes that card from the deck. If you're using two decks, you dont get that happening. Of course, if you're using tarot cards for a game where they replace dice, whether the card is inverted or not might not be important at all.

I was just coming here to ask about this. The Crimson Cutlass Omnibus was just released and it uses Tarot, and the reading of each card is based on whether or not the card was inverted. Because of other decks I have used, I knew that inversion didn't happen in shuffling on Roll20, at least not from any settings I had seen. That would be a nice optional checkbox on decks.

If you want an API script to automatically randomly invert played cards, let me know. 

Hi The Aaron, I would be interested in having access to randomly inverted cards when drawn from a custom deck.  :-)

You’d have to have a pro subscription to take advantage of the API method. If you want to see it it’s worth it yo you, I could create a game for you to try it in. 

Here's the script: on('ready',()=&gt;{ on('add:card',(obj)=&gt;{ if(randomInteger(2)===1){ obj.set('rotation',180); } }); }); Here's a game where you can try it out:&nbsp; <a href="https://app.roll20.net/join/3666748/GymU8Q" rel="nofollow">https://app.roll20.net/join/3666748/GymU8Q</a>

Aaron, how would you change that script so its only triggered by a single deck, say with the name Tarot. I often have extra decks in a game, used for things like one-use items and hero point tokens.

It gets slightly complicated, but not too bad: on('ready',()=&gt;{ const flippingDeckIds = []; findObjs({type: 'deck'}) .filter( (d) =&gt; /^Tarokka/i.test(d.get('name')) ) .forEach( (d) =&gt; flippingDeckIds.push(d.id) ); const isFlippingDeck = (cardid) =&gt; { const lookup = {}; if( lookup.hasOwnProperty(cardid) ) { return lookup[cardid]; } let card = getObj('card',cardid); lookup[cardid] = flippingDeckIds.includes(card.get('deckid')); return lookup[cardid]; }; on('add:card',(obj)=&gt;{ if( isFlippingDeck(obj.get('cardid')) &amp;&amp; randomInteger(2) === 1 ) { obj.set('rotation',180); } }); }); I build a list of the deck ids in flippingDeckIds.&nbsp; I'm using findObjs() to get all decks, then .filter() is checking the name (here I'm seeing if they start with Tarokka as I have those available for testing), then add the ids to the list. When a card is added to the table, it actually comes in as a graphic of the subtype card, so I built a function called isFlippingDeck() and pass the cardid from the graphic to it.&nbsp; That function does some caching, but basically gets the card from the card id and looks to see if its associated deck id is in the list of flippingDeckIds, returning true or false. The rest of the logic is the same.

Thanks. I'm glad I asked. That's more complicated than I expected! Also, FlippingDeck makes me giggle, thats a clever name.

Cool. Does a member have to upgrade their account in order to implement OR to actually use the provided script?

You need to be a Pro user to be able to create campaigns that use API scripts like this.&nbsp;

Okay, so if I wanted to have a game that included this functionality, I would have to be a Pro Subscriber. Would any other people/players who played in this game need to be a Pro Subscriber too, or not?

All features - dynamic lighting, scripting, etc., are dependent just on that one person's subscription level.

Only the creator of the game (not necessarily the same thing as the DM) needs to have a subscription in order for the API to function within that game. Some scripts do require coding to ensure that players can trigger an event, but I'm guessing this is not the case with this script, since it triggers on a card pull, which anyone can do. Aaron can answer that last part definitively, though.

keithcurtis said: &nbsp;I'm guessing this is not the case with this script, since it triggers on a card pull, which anyone can do. Aaron can answer that last part definitively, though. Absolutely right.&nbsp; Anyone pulling one of those cards to the table causes it to have the chance to be inverted. Interestingly enough, if you only wanted certain players to trigger that behavior, it would be impossible with the API.&nbsp; The add:card &nbsp;event (and all events that aren't chat:message, actually) contains no information about who instigated the event.&nbsp; This is why scripts like TokenLock must infer who could have caused an event. (In TokenLock's case, if a token has a controlled by, it might have been a player, so it disallows movement, but things without a controlled by can be moved willy-nilly as only a GM could have done that.)

Thanks to all. I've upgraded to Pro and have successfully included the shared script for my game. I was worried that I was going to need to redo all 78 cards, but it's working as is.&nbsp; :-)

GREAT!&nbsp; Let me know if you have any other API questions!
