Fairly simple. There is some automation as far as keeping track of miles traveled and keeping track of player’s scores but nothing too complicated.
In this case, when a mileage card is placed on the table top, it’s given a command to add it’s dynamic property value (the number of miles) to a global property called “Player[x]Miles” with x being the player side. There’s a text label that sits above the mileage area that displays the value of “Player[x]Miles”. That’s it …except that what it displays to me is different that what it’s displaying to my buddy.
I have changed the manner in which miles are kept track of but I haven’t caught my buddy online to playtest it yet. I’ll give you and update later.
