....fla....too...large....to....DL......

you say you want random y movement from a clip moving from left to right? Is this what I understand?

As far as I hear it you've got the movement going but you want to be able to check if the object is yet at a set _x. Is that right? That's a simple getProperty loop...

ok so i got these enemys that scroll across the screen but they olny can move in a straight line along the x cord i want it so they still move along the x cord but i want them to have an up and down mothion when the enter the screen (making it a little harder

[Jesse]

OK here's some code I threw together to make an MC move up or down:
onClipEvent (load) {
this.upper = 180;
this.lower = 280;
this._y = (upper+lower)/2;
this.yDir = random(10)>5 ? 1 : -1;
}
onClipEvent (enterFrame) {
if (upper>this._y) {
this.yDir = 1;
} else if (lower<this._y) {
this.yDir = -1;
}
this._y += 4*this.yDir;
}
The upper and lower variables define the top and bottom _y. You can make them random...
