horizontal scroll

[nigel]

I have a small flash movie that the user can control with their left / right
arrow keys.

I want to be able to stop the user scroll past the end of an image that I
have in there. How do I limit it.

The code i am using at the moment is as follows.

onClipEvent(enterFrame) {

if(Key.isDown(Key.LEFT)) {
this._x--;
}
if (Key.isDown(Key.RIGHT)) {
this._x++;
}
}

Why not just use the built-in ScrollPane UI component? No code needed at
all then.

I did the scroll on [url]www.emasavahl.com[/url] based on the mouse position relative
to the screen, but it can easily be done with a KeyPress command. The
limiting factor, as you put it, is the _x coordinate of the graphic on the
screen. As long as object._x is less than 10, it can scroll right, and as
long as object._x is greater than (-1*(object._width - stage._width)) it can
scroll right. (I think the concept's correct -- not the code -- someone can
correct me or I will march back with my tail between my legs and put the -1
where it belongs.)

basically, keep the left edge of the object within the screen (I use x =
10), and keep the right edge of the object in the screen, by subtracting the
screen width from the object width, and multiplying by -1. The code was
pretty short.

correction: should read:
