hey guys
been a follower for a long time (from a distance) but a client has suddenly pushed a problem onto me and i need to get it fixed, i’m hoping someone is helpful enough, so i’ve signed up 
basically i have an image 700 pixels long.
350 pixels are masked and viewed
arrow left, arrow right.
arrow right scrolls the image one way slows down to a stop, arrow left the other way.
however, i am struggling with this as i cant get it to work properly.
i realise i need to use a simple tween.class but i havent done it before and i’ve been trying to work it out all day 
if anyone could post up some simple code, i’d be really grateful.
thanks in advance
