Do drop targets have states recording if drag object have been dropped into them?
I'm working on a somewhat complicated drag and drop interaction that, frankly, is probably a bit silly, but I am using it as an exercise to see if I can get it to work in Storyline 2.
My screen has 4 statements which learners must evaluate as either true or talse. There is a drop target to the right of each statement, and to the side, 8 drag objects: 4 labeled True and 4 labeled False. The idea is to not let the learners know how many of the statements are true or false by counting the number of True and False drag objects. So there are enough of each to fill all 4 drop targets (i.e., 4 True and 4 False).
I have the whole thing working under normal circumstances, but it fails if someone drops, say, a True drag object to a correct drop target, and then drops another True to the same drop target. I have triggers which count how many correct drops have occurred, and this count gets messed up if someone drops two correct drag objects to the same drop target.
My question: Can I check the state of the drop targets somehow to see if they are empty or have something dropped in them? If so, what are the names of those states? If not, what would you suggest instead as a work-around?
