How to stop scrolling mc disappear off edge of stage?

[lilymayhew]

Help!

I've being going crazy trying to work out how to stop a scrolling movieclip stop scrolling when it reaches the edge of the stage, using Flash 8.

I've been trying to work out an IF function that detects if the ._x is =< 1, which - if I could get it to work, would either

A) Simultaneously stop the scrolling and make the right scroll button disappear

or

B) Seamlessly generate a copy of the scrolling movieclip appear at the end of the disappearing one to give the impression that it was endless

Can any one PLEASE help?

try this:

1.) change yo FPS to NOT be 12..use something like 33

2.) you mov_thumbs.. edit it.. so its not in the middle/centered..have the edge start at X:0

3.) use this code:

stop();
but_right.onRollOver = function() {
    mov_thumbs.onEnterFrame = function() {
        this._x += 4;
        if(mov_thumbs._x >= 0){
            trace("edge reached");
            delete mov_thumbs.onEnterFrame;
        }                    
    };
};
but_right.onRollOut = function() {
    delete mov_thumbs.onEnterFrame;
};

but_left.onRollOver = function() {
    mov_thumbs.onEnterFrame = function() {
        this._x -= 4;
        if((mov_thumbs._x + mov_thumbs._width) <= Stage.width){
            trace("edge reached");
            delete mov_thumbs.onEnterFrame;
        }
    };
};
but_left.onRollOut = function() {
    delete mov_thumbs.onEnterFrame;
};
