I’ve been working on a flash simulator to show what our night vision product would look like in the dark. I have been successful in making it work with the following code below. Yet I cannot add a “reticle” image (or symbol) to the draggable mask to make it work. Can someone help me with the code? I looked for hours on the internet and I cannot get it to work. I am new to Flash but am starting to learn as much as I can.[/FONT][/COLOR]
