The above subject and this video clip explains what I am trying to do for a similar project.
I made nine red square sprites and placed them over the previous background and I'd like them to randomly flash yellow like in the video clip shown. When a button is pressed to stop the flashing, I'd like only that flashed square removed with the press of another button. Along with another button to reveal the whole picture.
If anybody as some information for me, I'd greatly appreciate it.
