Moving Movie clip with button

Question

Hello AS wizards everywhere. Can anyone help with this. I
have a movie clip which displays a very long horizontal line of
thumbnail movie clips which will eventually have actions attached.
Right now, I'm trying to find a way of moving the long line to the
left or right by 165 pixels. The movie clip I want to move has an
instance name "scrollalong" and is part of a movie calIed "scroll
thumb nails". I wish to do this with 2 buttons residing on the main
timeline called "go left" and "go right". Once I've got to a
certain point with the "scrollalong" clip I want to disable the
button action so that it won't move.

thank you from a frustrated musician

You'll need to define the right limit point and the left limit point of the scrollalong clip. I'm guessing that the left limit point will be the starting point of the clip. And, that the right limit point will be 165 X the number of thumbnails in the clip.

So you could use something like this from the main timeline:

var leftLimit:Number = scrollThumbNails.scrollalong._x;
var rightLimit:Number = leftLimit + (165 * number of clips);

leftButton.onRelease = function() {

if (scrollThumbNails.scrollalong._x > leftLimit) {
scrollThumbNails.scrollalong._x -= 165;
}
}
rightButton.onRelease = function() {
if (scrollThumbNails.scrollalong._x < rightLimit) {
scrollThumbNails.scrollalong._x += 165;
}
}
