Thanks for letting me know about that, Jonathon. I’ve updated my permissions. I will also post the commented custom javascript code I wrote below.
Begin Experiment:
//define the Fisher-Yates shuffle function
function shuffle(array) {
var currentIndex = array.length, temporaryValue, randomIndex;
// While there remain elements to shuffle...
while (0 !== currentIndex) {
// Pick a remaining element...
randomIndex = Math.floor(Math.random() * currentIndex);
currentIndex -= 1;
// And swap it with the current element.
temporaryValue = array[currentIndex];
array[currentIndex] = array[randomIndex];
array[randomIndex] = temporaryValue;
}
return array;
}

Also begin experiment:
var test_trial = 0;
Execute at the beginning of each trial loop:
var curr_trial = trials[test_trial];
switch (curr_trial) {
case 0:
var shape1 = s1a[test_trial];
var shape2 = s1a2[test_trial];
break;
case 1:
var shape1 = s1a[test_trial];
var shape2 = s2a2[test_trial];
break;
case 2:
var shape1 = s1b[test_trial];
var shape2 = s1b2[test_trial];
break;
case 3:
var shape1 = s1b[test_trial];
var shape2 = s1c2[test_trial];
break;
case 4:
var shape1 = s1b[test_trial];
var shape2 = s1b2[test_trial];
break;
case 5:
var shape1 = s1b[test_trial];
var shape2 = s2c2[test_trial];
break;
}
curr_mask = masks[test_trial];
//thisExp.addData("Trial_Type", curr_trial);
//thisExp.addData("Item1", shape1);
//thisExp.addData("Item2", shape2);
//thisExp.addData("rotation", rotate);
test_trial = (test_trial + 1);
