Articulate Storyline 360 - How to make a analog stick for interactive menu navigation

You have two problems.One is that the motion paths are for the system, so you can't really force the user to drag an object on a specific path.  The other is that when you are dragging an object, it always sticks to the cursor, no matter what happens, until the mouse is released. (You can see this in action by removing one of the Masks and dragging the stick to that spot.) So the real trick is to get the learner to release the mouse at the appropriate moment. The attached sample shows one way to do that. I left outlines on the rectangles to illustrate how it is done, but you can take them off. I only did states and triggers for three options. Just copy them and make the necessary changes for the other three.  If you want it to wrap around, you could change the triggers to do that, too.

By putting the triggers on layers, I avoided having to create copious amounts of conditions to decide which trigger to fire when.
