I would like to designate certain locations on a scrolling background to appear. The background will only scroll through once, so it will not be repeating. I have made images appear on a static background by using the choose() methods to make the image appear at particular x - y combination, like so:
choose (100, 200, 300, 400)
choose (150, 250)
Using this method, the images appear at the particular spots I want, but the spots where the images can appear can only be in a grid format. I would like to have more variation in the image locations, and I want scrolling backgrounds as well.
I have briefly looked at image points to designate these spots on a large background image that is several times the width of the viewport, and when that part of the background comes into view, then that spot may receive a new image (randomly selected). Do you think something like that would work, and is there a method to determine if an image point is within the viewport? Or perhaps a different method?
