Dealing with large number of triggers/varriables and states - Using Cards

You can use text fields in Storyline as arrays... Here is an old sample of mine showing how you can setup a textfield in Storyline to act as an array.

When you showed some element of the array, its easy to remove with this code..so it never will show again.

var array = [1,2,3,4,5,6,7,8,9,0];

function arrayRemove(arr, value) { 
    
        return arr.filter(function(ele){ 
            return ele != value; 
        });
    }
    
    var result = arrayRemove(array, 6);
    // result = [1, 2, 3, 4, 5, 7, 8, 9, 0]
