Drag and Drop that Shows Slide Background
I want to create a slide in which the learner drags a shape (looking like a magnifying glass) across an image and reveals different items as they do it.
I am thinking a drag drop interaction with a slide background image containing the items, then the same image on top without the items and a shape set to show background.
When I preview, as soon as I click the shape it is permanently filled with the background image where it was placed. I can move it all over the screen but the image inside the shape remains the same.
Advice? Link to a slick tutorial?
Thanks in advance!
