X-axis scrolling gallery AS2

[DavidLeeCo]

Hey guys and gals!

I have been creating a gallery and there are some specific task's it needs to do.

1) scroll only X-axis when user clicks image
2) when release images move with inertia
3) if images are not resting in final position then the image must move.

so I guess the first thing I have been having trouble with is using

startDrag() but to specify only the X-axis??

any help would be nice!

Little more about the project. Images must scroll off the stage.. Images are all lined up in a row on the x-axis. user can sellect images and scroll feature is implemented when selecting a thumb OR user drags to the left to reveal no image coming in from the right.

I am trying to disable the y axis move so it only scrolls X-axis.

MovieClip.prototype.onPress = function() {
this.drag = true;
this.startDrag(false);
this.xPos = this._x;
this.yPos = 0;

this.onEnterFrame = function() {
if (this.drag) {
this.xSpeed = this._x - this.xPos; // x mouse speed
this.ySpeed = 0; // y mouse speed
this.xPos = this._x;
this.yPos = this._y=0;
} else {
this._x += this.xSpeed;
this._y = 0;
this.xSpeed *= 0.8; // decrease x speed by 20%
this.ySpeed *= 0; // decrease y speed by 20%
if (Math.abs(this.xSpeed) < 0.1 && Math.abs(this.ySpeed)< 0.0) { // if almost no movement, end enterframe loop
delete this.onEnterFrame;
}
}
}
}

MovieClip.prototype.onMouseUp = function() {
this._y=0;
this.drag = false;
this.stopDrag();
}

MovieClip.prototype.onRollOut = function(){
this._y=0;
}
