I located the following Actionscript 3.0 Class which performs the task of horizontally scrolling a picture in a continuous loop. Once it reaches the end of the picture, it then immediately starts over from the beginning of the picture. I am interested in making it so the picture fades in, scroll horizontally and then when it reachs the end of the picture, it fades out… It would then fade back in after a period of time and begin the process again of scrolling horizontally… Continuous loop. Can you please help me with adding those features to this Actionscript 3.0 Class? I would greatly appreciate it if you could directly augment the following code to in order to achieve this objective. I thank you very, very much.
