Use a tweening engine or the flash built in Tweening classes to move the .swf on the X axis. you need to time it accordingly so it looks like it's really moving..
Thanks for the reply. Any Actionscript 3.0 example code to achieve it.
Here a tutorial on how to use the Flash internal tween classes.
You know how to load an external swf right? If not see here: http://www.iheartactionscript.com/loading-an-external-swf-in-as3/
To achieve what you want to do...you'll ned to scroll the background.
The guy stays in place...i mean hes walking, but the background scrolls.Creates an illusion of a guy walking or whatever.....
I can post a fla fo you...just let me know where to.
If you want to make things easier, you can also copy all of the frames you have for the walking man and paste them into a movie clip. Doing that, you can not only put multiple instances of the walking man on the stage, but also move him around the stage without having to worry about moving each individual part together. In order to see the movie clips move you'll have to do a publish preview or test movie. Simply playing withing flash won't show the movie clip moving.
You can also put the scrolling background within a movie clip so it will repeat continually so long as the main timeline of the movie itself is still playing.
