Reset Drag-and-Drop Incorrect Choices w/ Motion Paths in Articulate Storyline 360

Hi, Jerry. 

Let's go back to the drawing board on this! Here's a suggestion that might be a good workaround for you: instead of using the Drag and Drop freeform question, let's use Pick one. 

The idea is, we'll tell Storyline to pick Correct (which is the green oval to the left of the slide view) if the objects are in the correct targets and Incorrect (the red oval) if that's not the case.

We will also use five hotspots instead of one, so we can have the object snap to center, and it will work like the Tile option under Drag and Drop.

Feel free to add more hotspots if you'd like to allow the user to drop additional objects.

The Try Again layer will have the same triggers you had previously, connecting the incorrect objects to the Motion Paths. 

Finally, I created four True/False variables (representing each of the four correct objects, and they turn True when the objects are dropped on the hotspots). I did this to delay the drop correct state (turning the textbox green) until the submit button is clicked.

The explanation might make more sense when you take a look at the attached .story file.

Let me know if you have additional questions!
